Brent Topsides Decommissioning Programmes
After detailed technical and engineering studies, it was decided that the Brent topsides would be removed using the new single lift vessel (SLV) Pioneering Spirit commissioned by Excalibur AS (part of the Allseas Group) and transported to the Able Seaton Port (ASP) facility at Teesside, operated by Able UK Limited (Able), for dismantling, recycling and disposal. This single lift technique will substantially reduce the risk, cost and environmental impact of the operation.
As part of the phased programme of offshore work, it was recognised that the Brent Delta topside would be ready for removal ahead of the formal approval of the wider Brent Field DP. It was agreed with the UK Regulator that a separate Brent Delta Topside Decommissioning Programme would be submitted
Following a thirty-day public consultation in early 2015, the Brent Delta Topside DP submitted by Shell recommending that the 24,200 tonne ’topside’ of the platform is removed in one piece by the SLV Pioneering Spirit was approved by the UK Government in July 2015.

The approval was a milestone for the project which began in 2006 and has seen engagement with stakeholders from over 180 organisations, including NGOs, academic institutions and independent scientific experts.
Following completion of the thorough topside preparations, the Brent Delta topside was removed on 28th of April 2017 and transported in May to the Able Seaton Port (ASP) facility at Teesside. Able processed the materials from the topside including asbestos, LSA/Norm and large amounts of steel.
Dismantling of the topside was completed in February 2019, and ultimately 97% of the Brent Delta topside by weight was either reused or recycled.
The Brent Delta Topside Close-out Report describes the offshore and onshore programmes of work to cut, lift, remove, dismantle, reuse, recycle and dispose of the Brent Delta topside. This report also covers the work to fit concrete caps and Aids to Navigation (AtoN) on top of the legs of the gravity based structure (GBS).

The Brent Field Decommissioning Programmes document described proposals for decommissioning the facilities in the Brent field, including proposals for decommissioning of the topsides of Brent Alpha, Brent Bravo and Brent Charlie (the Decommissioning Programme for the Brent Delta topsides having previously been approved in 2015).
The consultations provided the opportunity for consultees to raise comments on our remaining three topsides proposals. In accordance with UK decommissioning procedures BEIS had sight of our response to the comments raised by consultees in relation to the topsides, and informed us that they were satisfied that they have been addressed appropriately, and that no further consideration of proposals for the topsides was required as full removal is mandatory under OSPAR Decision 98/3.
As is to be expected when decommissioning involves large steel jackets or concrete gravity based structures, BEIS consideration of decommissioning proposals for these structures occurs over an extended timeframe to enable a robust review. Removal of topsides has no bearing on identified options for decommissioning of the Brent Alpha jacket or the Brent Gravity Based Structures, and for the management of materials in the base of the GBS legs.
In these particular circumstances, and given the timeframe involved, BEIS recognised that the execution of the remaining topsides removals can allow decommissioning to be executed cost effectively, to the benefit of the taxpayer, and without prejudice or compromise to the feasible decommissioning options for the jacket or GBS.
To this end, BEIS agreed that our topsides decommissioning proposals for Brent Alpha, Brent Bravo and Brent Charlie could be removed from the current Brent Field Decommissioning Programmes document and form a separate Brent Field Topsides Decommissioning Programme. We submitted this to BEIS in July 2018 and it was subsequently approved in August 2018.

There is no change to the OSPAR consultation process for the rest of the Brent Field Decommissioning Programme, and there is no change to any of the recommendations. We remain confident that our recommendations for the full field are safe, technically achievable, financially and socially responsible, and environmentally sound.
Following extensive topside preparation works, the Brent Bravo topside was removed on 18th of June 2019 using the SLV Pioneering Spirit. It was transported to the Able Seaton Port (ASP) facility at Teesside, where it is currently being dismantled by Able UK Limited.
The Brent Bravo Topside Decommissioning Progress Report describes the offshore programme of work carried out to cut, lift and remove the Brent Bravo topside and fit the caps and Aids to Navigation on top of the legs of the gravity base structure (GBS).
A final close out report will be submitted within twelve months of the completion of all the onshore operations to dismantle, recycle and dispose of the topside.

Brent Pipelines Decommissioning Programme
Having completed public and statutory consultations in 2017 for the Brent pipelines, as part of the Brent Field Decommissioning Programmes document, BEIS have since agreed that the proposals for the pipelines could be removed from the main document to form a separate Brent Field Pipelines Decommissioning Programme. We submitted this to BEIS in February 2020 and it was subsequently approved in March 2020.

Alpha Jacket Decommissioning Programme
Having completed public, statutory and OSPAR consultations for the Brent Alpha jacket as part of the Brent Field Decommissioning Programmes document, OPRED agreed that the proposals for the Alpha Jacket could be removed from the main document to form a separate Brent Alpha Jacket Decommissioning Programme. We submitted this to OPRED in April 2020 and it was subsequently approved in July 2020. We remain confident that our recommendations for the full field are safe, technically achievable, financially and socially responsible, and environmentally sound.
