On 14 October, the company has successfully installed the new 700t processing unit onto the platform, which is situated 230km northwest of Aberdeen.

The Kinnoull field, one of three reservoirs that are being developed as part of the rejuvenation of the Andrew area, will be connected to the Andrew platform.

BP North Sea business regional president Trevor Garlick said the Kinnoull project is significant to the comapny’s North Sea business.

"Advances in our understanding of the reservoir structure, deployment of the very latest in UK subsea engineering skills and a major upgrade of the Andrew platform are key success factors of this development," he added.

"The other important point about this project is that investment is occurring largely in the UK, with around 90% of the £700 million being invested in England and Scotland. At its peak the project has created employment for over 1,000 people in the UK."

The project also installed a new subsea system and caisson onto the Andrew platform to access the new reservoir.

Four subsea pipeline bundles with a total length of 28 km – the longest bundle system in the world – will carry the fluids to the Andrew platform for processing and onward export, the company said.

BP holds 77.06% interest in the project while its partners, Eni (16.67%) and JX Nippon (6.27%) own the remaining stakes respectively.
