Client: BP

Location: Central North Sea, UKCS

Scope: Duty Holder in decommissioning

In 2016, Petrofac was awarded a Duty Holder contract from BP to support the late life management and decommissioning of the Miller platform.

Within this scope Petrofac managed all aspects of on and offshore activities in support of BP’s decommissioning programme.

The last day of production on Miller was in July 2007. BP undertook well abandonment and topsides clean up on the asset before the project team completed the topside removal in June 2018. Successful removal of the jacket followed in August 2018.

Our responsibility as Duty Holder enabled BP – as licence owner – to remain focused on removal activities, while we ensured safe operations, asset maintenance and integrity throughout the preparatory and removal works.

Collaboration is key

Early engagement was key to our approach. It allows us to support clients in optimising the planning and execution of decommissioning services and support the transition of risk between operator and contractor. It also offers the opportunity for open dialogue around roles and responsibilities.

Once an asset moves to the decommissioning phase, mind-sets must also transition, from an ‘operations’ to ‘project-led’ culture. This ensures that decommissioning activity is not hampered by systems and processes designed for ongoing operations, and that removal is conducted safely and efficiently within the Safety Case environment.

By engaging early with BP, we could help facilitate fit-for-purpose on and offshore organisation and service structure. In addition, we developed an integrated team culture with the heavy lift vessel contractor, working together during the preparation phase across logistics, onshore/base/storage, waste management, permit development and job planning to allow for a tailored execution model.

By working collaboratively in this way, using project specific on and offshore management and delivery teams, we achieved many key successes for the Miller project.
