UK-headquartered energy heavyweight Shell has spent years ticking off items from its decommissioning list for an asset in the North Sea, which is seen as one of the deepest offshore oil fields in the world. The arrival of the field’s fourth and final platform to Able Seaton Port (ASP) in Hartlepool marks a new milestone in this undertaking.

Shell embarked on the long-term decommissioning planning activities for the Brent field in 2006, after the field life was extended beyond expectations with the redevelopments that enabled the asset to be served by four large platforms – Alpha , Bravo , Charlie , and Delta .
