There is no platform or rig in the vicinity, but occasionally fishing vessels may pass near the site. The guard vessel will ensure a safe distance is maintained between any passing vessel and the site.
Shell became aware of this unexploded ordnance in 1993. Since that time the company has regularly inspected the site and sought professional advice on how best to proceed. The consistent advice the company received was to leave the mine in position and continue to monitor it periodically.
The development of new technology means that Shell believes it may now be possible to remove the mine. Shell is considering technical options for the safe removal and disposal of the unexploded ordnance. A decision on how best to proceed is expected before the end of the year.
