Brent Field Decommissioning

Title: Brent Alpha MASTER

Duration: 13:05 minutes

Description:

The Brent oil and gas field, lying north east of the Shetland Islands, has been a cornerstone of the UK's hugely successful oil and gas industry. The next step in the life cycle is to decommission the Brent Field's four platforms and their related infrastructure.

This video describes the single-lift removal of the Brent Alpha platform topside and jacket, as well as the jacket’s removal to a Norway for recycling.

186 kilometres off Scotland’s Shetland Islands stands Shell’s Brent Alpha platform.

[Video footage]

Slow zoom-in on a Brent platform in deep water, cloudbank visible low on the horizon. Cut to a closer view, on level with the topside, of the platform. Another view, in moody lighting, of the platform on level with the topside.

[Voiceover]

After almost half a century, this giant structure is being dismantled.

[Video footage]

Low-angle view looking up at the Brent Alpha platform, followed by a view of two lifeboats suspended on the side of the platform just below a sign reading Shell/Esso Brent A. Next, we see a distant aerial view of the platform, with two small ships close by. Time-lapse footage of the platform in the distance as seen from the bows of a vast, twin-hulled construction vessel Pioneering Spirit. Then reverse-angle view of three men in the bridge, looking out across the water to the nearby platform. One of the men is using binoculars. Cut to footage looking directly down through an out-of-focus grate at four huge tube-like structures surrounded by a network of rusty pipes and a choppy sea.

[Voiceover]

It’s an epic engineering challenge ten years in the planning...

[Video footage]

A series of close-up angles of a man in full safety gear lighting an acetylene torch and then cutting through a huge metal tube, a spray of bright sparks flying as he works. Next, we see footage of the man now crouched low working beside the now sawn-through tube. Other men in safety harnesses and gear stand by. The ocean swell rises and falls just a few feet below the temporary scaffolding platform on which they work. Cut to footage of two men using acetylene torches to cut through dismantled tubes on the deck. Interior footage of a man closely observing a bank of screens.

[Voiceover]

Safely lifting almost 30,000 tonnes from the North Sea, one of the most hostile environments on earth.

[Video footage]

Low-level cloud clears to reveal aerial footage of the Pioneering Spirit, two helipads visible. Cut to high-level aerial footage of the Iron Lady barge and the Sleipnir in turn, each moving across deep, dark open ocean, leaving a pale blue wake. A bird’s-eye view of vast open ocean and low cloud cover, with the Sleipnir in the foreground, enormous twin cranes on the ship’s bows bearing a massive steel structure of pipes and beams. Next, aerial footage as the camera pans slowly along the length of the Sleipnir in a quiet harbour flanked by steep hills. Next, we see a small vessel, dwarfed by the Sleipnir, leaves a wake that trails from the Sleipnir’s aft as it makes its way across the glassy-surfaced harbour. Then, from deck level, looking down into rough sea between the Pioneering Spirit’s twin hulls.

[Engineer]

Whoa! Man, that’s something!

[Video footage]

Waves battering two massive semi-submerged pipes on the vessel’s side. Next, a close-up of a grinning engineer in safety gear, standing in front of a forest of rusty pipes, speaking to camera.

Brent Alpha…

[Video footage]

Low-level aerial view across a moody seascape, patches of sunlight breaking through the low cloud cover to create bright silver patterns on the flat sea.

[Voiceover]

It’s the third of four Brent Field oil and gas platforms being removed by Shell.

[Video footage]

Close-up of a Brent platform against a shimmering sea and a pale blue sky. Extreme wide-angle footage of the four Brent platforms faintly visible as pinpoints stretched across the horizon where cloudy blue skies meet dark blue ocean.

[Voiceover]

Built during the 1970s energy crisis, Alpha’s construction is unique among the Brent platforms.

[Video footage]

A series of clips of archival footage of a Brent platform in its heyday. First, from a helicopter passenger’s viewpoint, as we fly slowly by, we see the platform in operation below, a massive flame issuing from a gas flare on its side. Another platform without the topside on it can be seen in the water just metres from the first platform. Next, from sea-level, a hazy scene of a platform in the foreground, with various other platforms and structures receding towards the left of the frame. Flames are visible issuing from the gas flares of two of the structures. Next, from a helicopter passenger’s viewpoint, as we fly slowly by, we see a close-up of the aft of a huge construction vessel alongside a platform. A large crane and lowered ramp are visible at the vessel’s aft. Cut to a sea-level close-up of framework of steel pipes under a platform.

[Voiceover]

Its sister platforms Bravo, Charlie and Delta each sit on concrete legs buried deep in the seabed.

[Animated sequence]

Computer-generated imagery allows us to see both the platform topsides, as well as the support system underneath each of the four Brent platforms. Bravo, Charlie and Delta platforms each has a massive submerged concrete gravity structure as its foundation. Alpha has a massive submerged splayed steel frame surrounding a huge central tube.

June 2019 Brent Bravo Decommissioning

[Video footage]

Close-up footage of a lift system lifting the Bravo platform free of its platform legs. Cut to reverse-angle view of William Lindsay, in full safety gear, observing from behind a railing the platform being lifted. He turns to camera, looking pleased. Cut to crew applauding from behind the railing.

[William Lindsay]

There we go.

[William Lindsay]

We brought them shore and we recycled the topsides. The construct of Alpha is slightly different. It sits on a steel structure called a jacket. That allowed us not only to lift the topsides and bring to the shore for recycling, but also that steel structure.

[Video footage]

Camera zooms slowly across red dunes towards the Brent Bravo platform in a small, quiet harbour, fluffy white clouds and bright blue sky in background. Next, we briefly see a closer view of the platform topside aboard a massive barge lying in harbour. The sunlight flashes briefly through a gap in the superstructure as the camera pans slowly left and down. Cut to a large marine salvage yard where men in red jumpsuits and safety gear are using acetylene torches to cut up steel parts from the platform. Close-up of the acetylene torch cutting through a curved metal sheet, sprays of red-hot sparks bursting from it. Cut back to a close-up of William Lindsay talking to an offscreen interviewer, and then a medium view of him talking to camera, seen against a blurry background.

[William Lindsay]

Bravo and Delta sit on three very large legs. We had the opportunity of going inside the legs and cutting from the inside.

[Video footage]

Close-up footage of William Lindsay speaking to camera, seen against a blurred background. Next, we see high-angle close-up footage of waves pounding against a concrete platform leg.

[Animated sequence]

Computer-generated video of three large semi-submerged platform legs. A bright blue laser-like line cuts horizontally through the circumference of each leg. The camera zooms out a little.

[William Lindsay]

With Alpha, it's a smaller platform which sits on six narrower legs. We're not able to cut it from the inside, so we had to figure out a way of how we were going to cut the legs.

[Finlay McPhail]

To get to the legs of the Brent Alpha Jacket and cut them, we use rope access techniques. Jon and the team will gear up and abseil down over the North Sea.

Medium footage of Finlay McPhail, clad in safety gear, talking to camera, against a sunny seascape. Then, a close-up of a man in safety gear, donning a climbing harness, underneath his feet a metal grate through which the sea can be seen just metres below. A close-up as the man tugs hard on a strap on the harness to secure and tighten it. Close-up of two men in safety gear and climbing harnesses, one of whom climbs over a railing on the metal grate above the sea. Looking up, we see a close-up of ropes and pulleys and a man’s hands clipping rope into a carabiner. Camera pans to the right, past a rusty metal column, to show sea swirling around the platform frame just above the waves. Next, looking directly down through a gap in the steel frame, we see a man suspended in harness just above the lowest portion of steel frame above the swirling sea.

Medium footage of a grinning Jon Morgan, clad in safety gear, talking to camera, seen against a background of infrastructure on a level beneath the topside. Then, first-person footage of feet rappelling down a rusty steel column which disappears into the blue swell below. Next, a scene from a distance away of two men rappelling rapidly down one of the four enormous corner columns of the platform steel frame, dark-blue ocean swirling metres below.

[William Lindsay]

Even on a flat day there’s swell of 1.5 metres. It’s never flat calm out there, so you need real nerve to abseil on top of sea which is moving.

[Video footage]

Close-up of William Lindsay’s face as he talks to an offscreen interviewer, followed by medium footage of him talking to camera, seen against a blurry background. He makes a dipping and rising motion with his hands to indicate the ocean swell. Next, looking directly down, we see swirling dark-blue ocean, followed by footage of two men in abseiling gear about on the lowermost part of the steel frame just metres above the surging swell. One of the men kneels on a scaffolding board suspended across a part of the platform’s steel frame, while the second man, clipped to belaying rope, swings past him and lands on the pipe.

[Finlay McPhail]

Rope access is a very technically challenging specialised skillset which allows us safe access to some very hard-to-reach places.

[Video footage]

Reverse-view close-up looking directly down on the back of a man in abseiling harness as he kneels on a narrow scaffolding plank next to a huge steel column, shimmering black sea below him. Rapid zoom-in downwards to show the two men in abseiling gear suspended by ropes as they work on flimsy scaffolding around the huge steel column, swirling sea metres below. First-person view of a gloved hand clipping a belay clip onto a rope encircling a huge steel column, swirling sea just below. Next, from a short distance away, looking across a framework of metal columns and pipes, we see the two men in abseiling gear still setting up, surging swell just below where they work. Then, looking directly down through a gap in metal girders, following belaying rope dangling through the gap and attached to a man making his way along a large steel pipe below, swirling sea just below him.

[Tristin]

We’re down the bottom of the leg, about nine or ten metres down. Warren is watching Jon’s back whilst he’s doing the hot work.

[Video footage]

Close-up of a man in safety gear and abseiling gear lighting an acetylene torch, ocean surface just below and behind him. Then, from a distance, looking past a huge metal column, we cut back to the two men working on scaffolding just metres above the sea, followed by footage from directly above of the two men working at the bottom of the huge metal column just above sea-level. Medium footage of Tristin first peering down the platform leg and then turning to talk to camera. Cut back to footage, looking directly down at them, of the two men working on the scaffolding just above the sea. Next, a close-up of one of the men applying an acetylene torch to the steel column, sprays of bright sparks flying as he works. A first-person close-up of the acetylene torch cutting through the steel column, leaving a scorched black incision, while the second man seen swings past to land on a pipe just above the sea.

Interview with Genevieve Martin

[Title]

Brent Health, Safety and Environment Manager

[Genevieve Martin]

I personally wouldn't want to be hanging five metres from the North Sea. It's very cold. You're looking at about five degrees. So, if someone does fall into the sea, we need to get to them within a matter of minutes and get them out safely.

Cut back to the two men in abseiling gear working on the large steel column just above sea-level. First-person footage, looking past rope and rappelling device, of the man using an acetylene torch to cut through the steel column.

[Finlay McPhail]

We have an emergency response-and-rescue vessel on standby at all times. If someone falls in the water, they’re able to pull them out in under four minutes.

[Video footage]

From just above the helipad of a ship, we see a small craft approaching rapidly across open ocean, cloudy grey sky in the background. Medium footage of Finlay McPhail talking to camera, small emergency craft in the distance, cloudy blue skies and deep, blue ocean beyond. Cut back to footage of the men working on the steel column just above the ocean surface. Close-up of rusty metal pipe surrounded by swirling black sea. Cut back to a close-up of the man using an acetylene torch to cut through the huge steel column. Next, a first-person view as we lean in to peer through a gaping, charred hole in the column to see a fiery, hazy view of the acetylene torch cutting through the opposite side of the column. The image blurs, leaving a red-hot, glowing patch in the inky blackness of the column’s interior.

[Voiceover]

It’s not just the chill of the North Sea posing a risk to the decommissioning team.

[Video footage]

Looking directly down through an out-of-focus grate at four huge tube-like structures surrounded by a network of rusty pipes and a choppy sea. Cut back to close-up footage of the man cutting through the steel column with an acetylene torch. Next, from a distance, across the water, we see the Brent Alpha platform in heavy swell, low cloud cover in the background.

[William Lindsay]

When there’s a big storm comes through, there's very large waves, up to 50 feet. So, if we cut the legs straight, then if a wave hits the platform, we could have some catastrophic outcomes.

[Video footage]

Medium footage of William Lindsay talking to camera, seen against a blurry background. Next, from a distance, across the water, we see the Brent Alpha platform in rough dark-grey seas, grey sky in the background. Looking directly down onto black, surging, rough sea.

[Voiceover]

Simple horizontal cuts don’t provide enough resistance against the force of storm waves.

[Animated sequence]

Computer generated imagery depicts a zoom in on the platform, shown in white against a blue-and-white grid depicting the ocean surface. As we zoom-in further to the legs, blue arrows showing the direction of travel of storm waves travel under the platform. The points at which the legs would be cut are highlighted in red, and red arrows travel from them in the same direction as the blue arrows.

[William Lindsay]

We have to develop another way of cutting the legs so that it can be lifted without it moving in the horizontal direction.

[Video footage]

Medium footage of William Lindsay talking to camera, seen against a blurry background. Cut back to footage of the two men in abseiling gear working on the flimsy scaffolding at the bottom of the steel column just metres from the sea surface.

[Finlay McPhail]

We’ve made what’s called a castellated cut. These castellations ensure that the topsides cannot slip off the legs.

[Video footage]

Reverse-view close-up of one of the men cutting through the steel column with an acetylene torch. First-person view of the acetylene torch cutting into the metal, bright sparks flying. First-person view of the back of the man cutting through the steel column, a blackened, smoking incision visible to his right.

[Voiceover]

Cutting interlocking notches and slots increases resistance, preventing the topside from sliding, while allowing it to be lifted vertically.

[Animated sequence]

Computer-generated footage zooms in on a pale blue depiction of one of the platform’s steel legs just above a grid depicting the ocean surface. Another animation shows us the cutting pattern in the leg. White arrows travel under the platform, and behind the leg a fan-shaped area glows white to show the deflected force. Then, an upward-pointing white arrow appears on the leg as the animation shows the upper section of the leg being lifted off.

[Voiceover]

For two weeks the team work around the weather...

[Video footage]

Close-up of waves battering two steel columns on the platform’s frame. Looking down from a little way off, we see crew rappelling down the steel legs of the platform, rolling swell below them.

[Finlay McPhail]

We’ve got a storm moving in. And it’s snowing again.

Next, looking out through a wet window at the choppy seas and grey skies, the helipad rises and falls dramatically with each swell. Fade to black.

[Voiceover]

It’s an historic moment in the life of Alpha. With cutting complete, the final personnel leave the platform.

[Video footage]

A series of scenes of Brent Alpha moored in vast open ocean. View from alongside the Brent Alpha platform of a crew member entering a covered walkway spanning the gap between the platform and an offscreen vessel.

[Finlay McPhail]

That’s the last man off Brent Alpha forever.

[Voiceover]

The challenge now is to lift the platform, using the largest construction vessel on the planet.

[Video footage]

Aerial view of the Brent Alpha platform some way off, a large vessel to the right beyond it, as well as a low cloudbank on the horizon to the right. Looking through the railings of a flight of stairs on a ship’s deck, the Brent Alpha platform stands moored centre-screen in deep ocean a little way off, seen against a blue sky.

[Voiceover]

Alpha’s jacket weighs in at around 10,000 tonnes, meaning, with a successful lift, Sleipnir will beat her own record. But before the team can lift, they need to cut.

[Video footage]

Slowly downward-panning footage of the twin cranes on the Sleipnir’s bow, blue sky and seas beyond. Aerial footage pans slowly downward following an array of cables dangling from one of Sleipner’s cranes, blue sky and seas beyond. Aerial footage draws slowly upwards and away from Sleipnir anchored in a vast, glassy blue ocean, blue skies beyond. Aerial footage pans towards Sleipnir’s bow and cranes, blue sea and grey skies beyond.

[William Lindsay]

It’s not just the six legs that we have to cut. There are a large number of supporting bracings which keeps the structure strong. And there's conductors and there's risers as well. So there’s in total 43 subsea cuts to be done.

[Video footage]

Medium footage of William Lindsay talking to camera, seen against a blurry background. Looking over a ship’s railing, we see a reinforced steel cage housing cable and other equipment being lowered into the sea alongside. First-person close-up of a steel frame hitting the water’s surface and submerging amidst a flurry of bubbles. Three onscreen displays fill the frame, each showing a different underwater aspect of Alpha’s steel support framework, fish swimming slowly by in one screen, with various readings and indicators displayed on each screen.

[Pieter Hendricks]

It’s a really exciting part of the project, because we’re going to use the world’s largest diamond wire-cutter. And, basically, we’re going to position it around the legs, and the diamond wire will slice through the leg.

[Video footage]

Medium footage of Pieter Hendricks, clad in safety gear, on the Sleipnir’s deck, talking to camera, seen against a backdrop of infrastructure. Looking up from the Sleipnir’s deck towards one of her cranes, we see a metal contraption, the diamond wire-cutter, being lifted slowly above the deck. Looking up at the diamond wire-cutter suspended by cables against an overcast sky. Medium footage of Pieter Hendricks talking to camera from the Sleipnir’s deck. Underwater footage of the diamond wire-cutter positioned against one of Alpha’s legs, then a close-up of the wire-cutter and the leg, followed by a close-up of a spinning belt on two pulleys.

[Voiceover]

In place, 85 metres under water, the cutter loops a thin steel wire over seven metres long around each segment. Encrusted with industrial diamonds, one of the toughest synthetic substances known, the cutter sets to work slicing.

[Animated sequence]

Computer-generated image depicting a section of Alpha’s legs, shown in white and pale blue, where the leg joins a horizontal bracing pipe. Slow zoom-in on an animation of a pincer-like device encircling the leg, just before the diamond wire-cutter positions itself just above the device. Two white arrows indicate the direction of movement as the arrows and diamond cutter slide forward, forcing the wire-cutter’s wire through the leg, and the top of the leg lifts up leaving the bottom half still clamped by the wire-cutter and pincer-like device.

[Video footage]

A monitor’s onscreen display fills the frame. On it we see three different aspects of the diamond wire-cutter working underwater as it cuts through the barnacle-encrusted Alpha platform leg.

[Voiceover]

But with four cuts remaining, they must call a halt.

[William Lindsay]

We have a hold point because it is a point of no return. We have what’s called a green cut and a red cut. So the green cuts means that if you cut through, then the jacket still has structural integrity, it will still sit there by itself.

[Video footage]

Title: Brent Bravo Lift MASTER (youtube)

Duration: 11:46 minutes

Description: 

This video describes the single-lift removal of the Brent Bravo platform topside, including the transport, towing, dismantlement and recycling of the topside.

Brent Bravo Lift MASTER (youtube) Transcript

[Background music plays]

The Sound of Shell orchestral adaptation plays as an intro, and adaptations of The Sound of Shell continue to play throughout the video.

[William Lindsay]

40 years ago, no one really thought about how they were going to be dismantled.

[Video footage]

We open on close-up aerial footage of the ocean as the shot tracks over the face of the waters.

[Voiceover]

After decades of service, the four Brent Field platforms are being decommissioned.

[Video footage]

The shot rapidly tilts up to a bird’s eye view of one of the concrete-legged Brent platforms in deep water, below a cloudy blue sky. The shot slowly zooms in, then we cut to a closer view of the topside, then back to a wider view of the platform.

[Kenny Thomson]

We got NASA to come and give us a hand, and they were blown away with what we were doing.

[Video footage]

High angle reverse view footage of an operator in a control room, seated in front of a bank of screens, his left hand on a joystick as he watches the footage and data displaying on screens facing him. This cuts to an extreme close-up in reverse view of a man watching footage displayed on one of the control room’s screens. Then we see aerial footage of a yellow inspection vehicle being lowered into the water. Next, close-up of Kenny Thomson speaking to an off-camera interviewer; in the background, we see the ocean and a deepwater platform topside is partially visible at frame-left. We cut back to high angle reverse view footage of an operator in a control room, seated in front of a bank of screens, his hands operating controls as he watches the footage and data displaying on the screens.

[Bethan Vasey]

We needed to be able to lift the platform up from underneath. It was never designed to be lifted in that manner.

[Video footage]

Close-up footage of Bethan Vasey speaking to the off-camera interviewer, seen against a blurred background. Next, we rapidly pull back on low-angle panning footage of the underside of a platform topside. Then we see high-angle close-up footage of waves pounding against concrete platform legs, followed by wide angle footage of the Brent Delta platform in deepwater below blue skies.

[Voiceover]

In 2017, Shell set a world record when Brent Delta was lifted intact…

[Video footage]

Panning bird’s eye view of the Brent Delta platform in deep water below cloudy blue skies. Next, we see alternating low-angle and high-angle time-lapse footage by night of the vast, twin-hulled Pioneering Spirit moving into position around the Brent Delta platform. We then see front-view wide-angle footage of the Pioneering Spirit moving through the ocean with the topside straddled aboard.

[Voiceover]

And taken away for recycling.

[Video footage]

Low angle footage of a lift system lifting the Delta platform free of its platform legs, followed by a bird’s eye view of the tops of the three platform legs protruding from calm, deep blue waters.

[Paul Corr]

Shell’s idea, which was the right idea, was just bring it in, the whole lot, as it stands.

[Video footage]

We see a bird’s eye view of the Pioneering Spirit moving through the ocean, bearing the Delta topside. Next is close-up footage of Paul Corr speaking to the off-camera interviewer; behind him, we see a pile of dismantled metal and industrial materials. Then we see time-lapse footage of the Delta platform at Able UK’s Able Seaton Port, being dismantled.

[Voiceover]

Now its Bravo’s turn

[Video footage]

Slightly panning aerial close-up of the surface deck of Brent Bravo.

[Bethan Vasey]

You’ve done it once. How are you going to do it again, and how are you going to do it better? And that’s the challenge that we’ve set to the team.

[Video footage]

We see close-up footage of an LED countdown clock, displaying days, hours, minutes and seconds. Next, we see reverse view footage of a crewmember rappelling down beneath the underside of the Bravo platform. This is followed by time-lapse side-view footage of the Bravo platform, the outer sections of the platform topside visible at frame-right while, in the background, we see the sun at the horizon and clouds racing overhead. Then we see high angle footage of Bravo crewmembers gathered in a room, mostly standing against the far wall on which a line of control panels is mounted.

[Voiceover]

So how do you turn 25,000 tonnes of steel…

Bird’s-eye-view footage of a shimmering sea surface fills frame.

[Voiceover]

The discovery of the Brent oil and natural gas field in the 1970s had a crucial impact on Britain’s economy.

[Video footage]

As though projected onto a screen, we see archival footage of a small vessel moving through the ocean, and we see the faint outline of an oil platform in the distance. This is followed by wide-angle footage of the deep water platform itself, then by ever closer shots of the topside, with the waves pounding against its cement legs.

[Voiceover]

Now Brent field has come to the end of its life, Shell is rising to a new challenge – safely dismantling its four huge platforms.

[Video footage]

Reverse view footage of a crewmember looking out over the ocean to the line of Brent platforms in the distance. This cuts to extreme wide-angle footage of the four Brent platforms faintly visible as pinpoints stretched across the horizon, at which point we see cloudy blue skies meeting the dark blue ocean.

[Animated sequence]

Computer generated imagery shows a slightly zooming wide view of the four platforms alongside one another in the ocean, base structures visible beneath the surface. Light flares across the frame in a transition effect.

Interview with William Lindsay

[Title]

Shell Brent Decommissioning Project Director

[William Lindsay]

There’s three main elements of decommissioning. One is isolating the reservoir.

[Video footage]

We transition to a wide-angle side view of the Bravo topside in deep water.

[Text displays]

William Lindsay

Shell Brent Decommissioning Project Director

[William Lindsay]

And we do that, what’s called plug and abandonment. So we basically seal all of the wells so that at no point can the hydrocarbons come out of the reservoir to surface. The next element is we have to get everyone off the platforms.

[Video footage]

Medium footage of William Lindsay speaking to the off-camera interviewer, seen against a blurred background. This cuts to reverse view footage of two operators in a control room, seated in front of a bank of screens, their hands on controls as they watch the footage and data displaying on the screens. Next, we see a close-up of the underwater footage displayed on the screens, followed by a high angle close-up of waves pounding against the platform legs.

[Voiceover]

The final stage is dismantling, and the decision was made not to attempt this onsite but to remove the entire upper platform, the topsides, as one unit.

[Video footage]

Low angle footage of a helicopter in the air, rotor blades turning against a deep blue sky. This cuts to high-angle footage of the Pioneering Spirit moving through the ocean with the topside straddled aboard.

Interview with William Lindsay continued

[William Lindsay]

We lift the topsides and we transport them to shore, and there, we dismantle. And then, as much as possible, we try and recycle. So, on Delta, for instance, we’re managing to recycle over 97%.

[Video footage]

Medium footage of William Lindsay speaking to the off-camera interviewer, seen against a blurred background. Next, we see wide-angle footage of several workers at the Able Seaton Port, working with welding torches as they dismantle steel components; piles of dismantled metal can be seen in the background and foreground. We cut to a close-up of the flame of a welder’s torch being applied to a seam in a piece of metal. Next, we see an Able UK excavator moving through the yard, followed by low angle footage of a claw dumping dismantled metal parts onto a pile of dismantled metal and industrial materials. Then we pull back on aerial footage of a pile of dismantled parts.

[Voiceover]

The whole Bravo lift has been streamlined to give a 70% reduction in preparation work.

Bethan Vasey

Shell Brent Decommissioning Project Manager

[Bethan Vasey]

We looked back on Delta and said okay, it was a success, but how can we do it even better, so that then, when we come to do it for Bravo, there was less work offshore. So, it was safer, it was more efficient, and it really meant that the overall removals part of the project was a step change.

[Video footage]

Close-up footage of Bethan Vasey speaking to the off-camera interviewer, seen against a blurred background. We cut to low angle footage of the platform topside seen against blue sky. Next, we see aerial footage of a vessel anchored alongside the platform, one crewmember standing in the visible corner of the surface deck closest to the vessel. Next, we see medium footage of a crewmember controlling a hoisted load of steel rods as it moves off the platform. This is followed by time-lapse footage of the camera moving across the steel grating floor of one of the platform’s decks.

Close-up footage of Kenny speaking to the off-camera interviewer; in the background, we see the ocean and the platform topside is partially visible at frame-left.

[Voiceover]

Bravo is firmly fixed to its 150-metre-high base. A new method was developed to cut it free without installing the steel bracing used in Delta.

[Video footage]

Close-up of Keana Jardine speaking to the off-camera interviewer, seen against the blurred background of a platform deck.

[Keana Jardine]

So this was done by core drilling into the concrete walls of the legs. This core was then removed, and a 300kg steel shear key was put in its place. Once these were all in place, a diamond wire cutter was then put in between each key and this then cut through the concrete wall.

[Animated sequence]

Computer generated imagery depicts a zoom in on the top of the platform legs, shown in white. These become partially transparent and we see the core drilling location and direction depicted in blue, then the core being removed, and the shear keys being inserted, depicted in yellow. The imagery zooms on a closer view of the shear keys at the top of one of the concrete legs as a diamond wire cutter, depicted in light blue, is inserted alongside a shear key. As the shot slowly zooms out, a light blue line encircles each platform leg at the point of the yellow shear keys, depicting the diamond cutter cutting through the concrete.

[Voiceover]

Shear keys play a vital role in securing the platform.

Shell Brent HSSE Manager

[Genevieve Martin]

We’ve got the gravity downwards force that holds us, but the shear keys also help us from a sideways perspective. If we have any large waves that come through here in the height of the winter or in the spring, then those shear keys hold us in position and stop any sideways or lateral force.

Interview with Keana Jardine continued

[Keana Jardine]

We learned a lot from Delta. There was a lot of welding involved with that kind of project. But on Bravo, we did the concrete lift points. So this reduced a lot of the welding under deck and, yes, reduced the man hours too, so a lot less risk of someone getting injured during the work.

We transition to close-up footage of a lift system lifting the Delta platform free of its platform legs. This is followed by close-up footage of Keana Jardine speaking to the off-camera interviewer, seen against the blurred background of a platform deck. Next, we see low-angle, tilting footage of a tall rectangular cement column, marked ‘LP5’, lift point five, followed by close-up footage of the underside of the Bravo platform in deep water, and a sign indicating ‘LP5 north face.’

[Voiceover]

Unwanted equipment is cleared away.

[Video footage]

Close-up of a note indicating ‘Decommissioned’ pegged to a piece of equipment on a lower deck of the platform.

Interview with Genevieve Martin continued

[Genevieve Martin]

We’ve been going around the whole platform bit by bit and, as you can see, the platform is looking quite bare now and lots of things have been backloaded by vessel and gone back to shore.

[Video footage]

We see panning wide angle footage of the bare interior of a lower deck of the platform. This cuts to aerial footage of a lifting hook lowering equipment onto a waiting vessel. Next, we see time-lapse bird’s-eye-view footage of loads being hoisted onto the vessel anchored alongside the platform, and we see the vessel moving off through the deep blue waters.

[Voiceover]

The crew prepares to leave, or Down Man.

[Video footage]

Low angle footage of a helicopter moving ever closer, rotor blades turning against a deep blue sky.

Interview with Kenny Thomson continued

[Kenny Thomson]

The Down Man process over the next week is all about making the platform safe and tidy in preparation for the lift, and so we get to a point where we have what we call the Golden Chopper, which is the final chopper that leaves the platform. As the chopper arrives, we will TPS, which is Total Platform Shutdown. So I’ll be in the control room, push the final button and then walk up to the chopper and get on the chopper. Then that’s us.

[Video footage]

Close-up footage of a sign attached to a slender chain strung across a section of platform, indicating ‘No Access, module cleared and secured for single lift.’ This cuts to close-up footage of Kenny Thomson speaking to the off-camera interviewer, seen against the blurred background of the control room. Then, we see footage of a similar ‘No Access’ sign pinned to a slender chain strung across a section of the lower deck of the Bravo platform, followed by circling high angle footage of a crewmember standing on the helideck, wearing a headset with microphone. Next is wide-angle footage of the helicopter on the helideck, rotor blades turning against the blue sky; several crewmembers are seen standing at various points around the chopper on the helideck. Again, we cut to close-up footage of Kenny speaking to the off-camera interviewer, seen against the blurred background of the control room. We cut to a close-up of a dial on a control panel, the sign below it indicating ‘Total Platform Shutdown.’ Next, we see slow-motion footage of crewmembers approaching and boarding the helicopter waiting on the helideck, followed by a close-up of the wheels/landing gear of the helicopter as it lifts off the helideck; in the background, we see Brent Charlie at some distance.

Interview with Genevieve Martin continued

[Genevieve Martin]

When people get on that final chopper and it flies away, that’s quite an emotional thing. We are saying goodbye to an iconic platform here.

[Video footage]

Low angle footage of the helicopter moving over the ocean, seen as a pinpoint against the blue sky. This cuts to time-lapse footage of the ocean glistening with shimmering light from the setting sun, and in the foreground, a corner of Bravo’s topside fills frame-left. Next, we see more time-lapse footage of night falling over the ocean and, in the foreground in frame-right, we see the silhouette of a section of Bravo’s topside, before fading to black.

We switch to time-lapse bird’s-eye-view footage of the Pioneering Spirit moving through shimmering ocean waters, approaching the shot, then slow to real speed.

Interview with William Lindsay continued

[William Lindsay]

So, as we approach the field we slow down and then we’re ballasting down at the same time, so going deeper in the water, because we’ve got fit underneath the platform.

[Video footage]

Slow-motion medium footage of William Lindsay walking along a deck of the Pioneering Spirit, then cutting to profile-view footage of William looking out the windows of the deck through binoculars. This is followed by extreme wide-angle footage of the Bravo platform in deep water at some distance while, in the foreground, we see some of the vast infrastructure comprising the Pioneering Spirit. Next, we see low-angle profile-view footage of William standing at the vessel’s windows, speaking to the off-camera interviewer.

[Voiceover]

Positioning the giant ship takes four hours.

[Tony Waites]

From now, we are in a standoff position outside the 500m zone. The next step is to move into close proximity around the platform, go underneath the platform with the bows of the ship, connect all of the lift points and then the next stop will be ready to fast lift.

[Video footage]

We see bird’s-eye-view footage of the Pioneering Spirit moving through shimmering ocean waters, approaching the shot, then cut back to close-up footage of Tony speaking to the off-camera interviewer, seen against the background of the bridge of the Pioneering Spirit. Next, we see medium footage of crewmembers working on the bridge of the Pioneering Spirit, then bird’s-eye-view footage of the Pioneering Spirit moving through the ocean, seen in side-view. This cuts to a wider view from the same angle, the twin hull of the vessel approaching the platform legs. Next, we see time-lapse footage of the twin hull with lifting arms moving into place on either side of the concrete legs of the Bravo platform, followed by high-angle footage of the tops of the platform legs as the Pioneering Spirit’s twin hull approaches. We cut to more bird’s-eye-view time lapse footage of the twin hull with lifting arms moving into place, straddling the Bravo platform legs and topside. This is followed by a slightly zooming bird’s-eye-view footage of the Pioneering Spirit with twin hull straddling the Bravo platform at dusk.

Interview with William Lindsay continued

[William Lindsay]

This whole operation requires very close coordination between a number of different departments. So one is the marine department, so the people who drive the vessel, if you like. One is the dynamic positioning department, so the people that control the thrusters that keep the vessel steady.

[Video footage]

We cut to a wider bird’s eye view of the Pioneering Spirit straddling the Bravo platform at dusk. This is followed by a video montage of different sets of crewmembers working in various control areas on the bridge of the Pioneering Spirit, where we see banks of screens displaying graphics and data. This cuts back to more bird’s-eye-view footage of the Pioneering Spirit straddling the Bravo platform at dusk.

12 GPS thrusters

80 tonnes

[William Lindsay]

And then we have the ballasting department. So these are the people that manage and ensure that the ship’s weight stays constant or according to plan…

[Video footage]

We see medium footage of crewmembers in a control area on the bridge of the Pioneering Spirit, followed by a close-up of a screen displaying graphics and data. Next, we see bird’s-eye-view footage of the Pioneering Spirit in the ocean, seen in side-view.

[Text displays]

87 ballast tanks

700,000 tonnes

[William Lindsay]

So that it doesn’t go left or right, up or down. And then we’ve got the people who manage the topside lift system itself. So the coordination of those four departments is absolutely the key in this. And that’s why they are all in the one big area on the bridge. It’s a very large bridge, but it’s actually four different departments working together.

[Video footage]

Close-up footage of William Lindsay standing at the vessel’s windows, speaking to the off-camera interviewer, followed again by medium footage of crewmembers working in a control area on the bridge of the Pioneering Spirit. Next, we see time-lapse close-up footage of the lifting arms on the Pioneering Spirit’s twin hull moving into place underneath Bravo’s topside. We then cut to close-up footage of William Lindsay standing at the vessel’s windows, speaking to the off-camera interviewer. Next, we cut back to bird’s-eye-view footage of the Pioneering Spirit straddling the Bravo topside.

[Video footage]

Extreme wide bird’s eye view of the Pioneering Spirit straddling the Bravo platform, surrounded by a shimmering sea.

Interview with Tony Waites continued

[Tony Waites]

In all weather conditions that we plan to do the lift, we don’t want the ship to move by more than plus or minus half a metre which accounts for the wind, waves, wave direction. So that all goes into the limitation of doing the lift.

[Video footage]

Time-lapse footage of the Pioneering Spirit’s twin hull moving in either side of Bravo’s concrete legs underneath the topside, seen from the point of view of the Pioneering Spirit. Next, we see medium reverse view footage of Tony and another crewmember standing at the bridge of the Pioneering Spirit, looking out towards the Bravo topside. This is followed by low-angle footage of the Bravo topside, and the Pioneering Spirit’s twin hull straddling it, cutting back to close-up footage of Tony Waites speaking to the off-camera interviewer, seen against the background of the bridge of the Pioneering Spirit.

[Voiceover]

Pioneering Spirit deploys cutting edge technology to connect its lifting arms to Bravo.

[Video footage]

Point of view footage of the sun rising at the horizon, seen through a porthole.

Interview with Tony Waites continued

[Tony Waites]

The innovation of the dynamic positioning and the active heave compensation which allows a ship that’s moving in the world to connect to something that’s fixed is impressive.

[Video footage]

Close-up low-angle footage of a lift arm connecting with the underside of the Bravo platform, cutting to wide low-angle footage of the lifting arms connected to the underside of the Bravo topside. Next, we see medium footage of crewmembers on the bridge, facing banks of screens displaying footage, graphics and data. This is followed by a video montage of time-lapse low-angle footage of lift arms moving in and connecting with the underside of the Bravo platform. Then we cut back to medium footage of crewmembers gathered on the bridge of the Pioneering Spirit.

[Crewmember]

I can confirm we are within half a metre.

[Video footage]

High-angle close-up of a crewmember’s hands on a document resting on a control panel, his index fingers holding place on the document. Next, we see a video montage of shots of crewmembers on the bridge, observing data on screens, and then, in response to a crewmember’s confirmation, some crewmembers approach the shot as they exit the area.

[William Lindsay]

Lots of people coming down the stairs, so it’s going to happen soon.

[Video footage]

Medium footage of William Lindsay standing at the railing of the Pioneering Spirit, speaking to the off-camera interviewer; in the background, we see the lift arms in place underneath the Bravo topside. Again, we see a montage of shots of crewmembers working on the bridge and observing data on screens.

[William Lindsay]

There we go!

Then we cut to close-up footage of Jeroen van der Sman speaking to the off-camera interviewer, seen against the background of the lifting Bravo topside. Again, we see footage of William Lindsay standing at the railing of the Pioneering Spirit, watching the Bravo topside being lifted, and we hear the crew applauding in the background. We fade to black.

PART 3 Tow – Skid

[Voiceover]

The final stage of Bravo’s journey is about to begin.

[Video footage]

Panoramic footage of the sun rising over the ocean. We cut to high-angle footage of the swirling and shimmering blue ocean waters, then to bird’s-eye-view footage of the Bravo topside aboard the Pioneering Spirit, shown in side-view, moving through the misty ocean.

Interview with Tony Waites continued

[Tony Waites]

Once we’ve lifted the topsides, that’s the point of no return, because you can’t put the topsides back down again. So basically, we have a clock that starts to tick. We have to sea fasten the topsides so it’s stable as we transport, and then we’ll turn around and install the leg caps with the navigational aids. That has to be done, including the 32-hour travel window, all within a 72-hour period.

[Video footage]

Again, we see low-angle time-lapse footage of the Bravo topside being lifted clear of its concrete legs by the Pioneering Spirit’s lifting arm system and then moving away from the legs as we track the Pioneering Spirit’s movement. This is followed by bird’s-eye-view footage of the Pioneering Spirit moving away from the concrete legs with the Bravo topside aboard. We cut to wider-angle time-lapse footage of the Pioneering Spirit manoeuvring as it turns around beside the concrete legs. Next, we see a close-up of a leg cap being lowered on top of one of the Bravo platform’s concrete legs. Then, we see wide-angle bird’s-eye-view footage of the Pioneering Spirit anchored alongside the concrete legs, now with the leg caps installed. We cut back to close-up footage of Tony Waites speaking to the off-camera interviewer, seen against the background of the bridge of the Pioneering Spirit.

High-angle footage of the shimmering surface of the ocean as the shot pans across the face of the waters. This is followed by a front-side bird’s eye view of the Pioneering Spirit moving through the ocean with the topside aboard.

Interview with Bethan Vasey continued

[Bethan Vasey]

The Pioneering Spirit sails down from the Brent field towards Hartlepool, and there, we carry out a transfer operation where the Iron Lady, which is an enormous barge in itself, comes and essentially docks within the Pioneering Spirit structure, and the two vessels work together so that the Brent Bravo topsides will be landed on top of the Iron Lady.

[Video footage]

Close-up of a ‘Brent B’ sign displayed against a corner of the Bravo topside as it moves through the ocean aboard the vessel. We cut to aerial footage of the topside aboard the Pioneering Spirit, and ocean water swirling below the moving vessel. Next, we see a close-up of a piece of equipment mounted at a corner railing, seen against a background of shimmering ocean waters. This is followed by close-up footage of Bethan Vasey speaking to the off-camera interviewer, seen against a blurred background. We next see aerial footage of the Iron Lady barge in the ocean, with tugs near each corner of the barge, and this cuts to wide-angle reverse view footage of crewmembers on the bridge of the barge, seen through large windows, as the barge moves into position. Next, we see low-angle footage of crewmembers working on the surface deck of one of the vessels; in the foreground, we see ropes and the railing and steel infrastructure at the side of the vessel. This is followed by time-lapse footage, by night, seen from various angles, of the topside aboard the Pioneering Spirit, and the tugs manoeuvring the Iron Lady barge in between the twin hull of the Pioneering Spirit.

[Voiceover]

The Bravo is lowered onto the Iron Lady by pumping out thousands of gallons of water ballast from the Pioneering Spirit, reducing the ships’ height by as much as 18m.

[Bethan Vasey]

Then, Allseas need to tow in the Iron Lady barge through the Seaton Channel towards the Able Facility.

[Video footage]

We see a video montage of the Bravo topside atop the Iron Lady, being manoeuvred down the Seaton Channel by the tugs.

[Bethan Vasey]

Now the barge doesn’t have its own propulsion. So we need four tugs to basically manoeuvre it down this channel safely, with the topsides sitting on top of it, at the right tidal conditions…

200 metres long

57metres wide

[Video footage]

The video montage continues, as we see, from various angles, the Bravo topside atop the Iron Lady, being manoeuvred down the Seaton Channel by the tugs.

[Bethan Vasey]

So that we can sail all the way in, in one operation. And then, Allseas will manoeuvre it in and moor it alongside the quay at Able.

[Video footage]

We see wide-angle bird’s eye view of the Bravo topside aboard the Iron Lady, being manoeuvred into Seaton Port. This cuts to aerial footage of the surface deck of the topside aboard the barge moving through port waters. Next, we see wide-angle side view footage of the topside aboard the barge, surrounded by the tugs manoeuvring the barge through the port waters; overhead, we see white clouds in a brilliant blue sky, and in the foreground, seagulls fly and swoop over the port waters.

Interview with William Lindsay continued

[William Lindsay]

The barge is just coming in and we’re trying to line up the middle of the barge with that yellow stick. So the gentleman standing with the radio, green hat, blue coveralls, he’s the barge master, he is in control, he’s the only guy that’s communicating to the four tugs. And at the moment, they’re manoeuvring into the right place. We have to get this very accurate because we’re going to install the bridges to bring the whole lot down.

[Video footage]

Circling aerial footage of the barge with topside lining up alongside the quay at Able. This cuts to medium footage of William Lindsay on the quay at Able, speaking and pointing towards the Iron Lady as it lines up at quayside. We cut to a closer view of the Iron Lady manoeuvring to line up with a yellow stick at quayside, then back to medium footage of William standing on the quay, pointing towards the Iron Lady as he speaks. Next, we see medium footage of the barge master and other crewmembers standing on the deck of the Iron Lady, as the barge master speaks into a two-way radio. This cuts to aerial footage of the tugs manoeuvring the barge, then to a side view of a tug moving next to the barge, and finally, to another aerial view of the tugs manoeuvring the barge.

[Voiceover]

It takes ten hours to push the Bravo ashore so that recycling can begin.

Interview with Bethan Vasey continued

[Bethan Vasey]

The Brent Field has been obviously part of oil and gas history for 40 years. And now, it’s amazing to see it both, first of all, come onshore, and then the way that it’s been processed and essentially sent away again in smaller pieces to be recycled is already pretty impressive sort of recycling of history.

[Video footage]

Extreme wide-angle time-lapse footage of the topside being moved along the tracks of the skidding system at Seaton Port, the entire process seen in daylight, then as night falls, and then in daylight again. Next, we see wide-angle footage of several workers at the Able yard, working with welding torches as they dismantle steel components; piles of dismantled metal can be seen in the background and foreground.

[Bethan Vasey]

And just being part of that journey, the final part of Brent, for me is like a massive honour and responsibility, to take it apart, to do that successfully and to show the industry that we can do a single lift dismantlement.

[Video footage and graphic]

We cut to close-up footage of Bethan Vasey speaking to the off-camera interviewer, seen against a blurred background. Finally, we close on time-lapse footage of the topside at the Able yard, starting to be dismantled; we see a crane moving about in the foreground as clouds race overhead.
