BP is ramping up its West of Shetland operations with the UK government approval to push ahead with the second phase of its giant Clair field development, Clair Ridge. Plans to redevelop the Schiehallion and Loyal fields with a new floating production, storage, and offloading vessel (FPSO) are also gathering pace.

The Clair reservoir is the largest known hydrocarbon resource on the UK Continental Shelf (UKCS), occupying an area of 220 sq km. It is located approximately 75 km west of the Shetland Isles in 459 ft of water. Because of its size and complexity, it is being developed in phases.

Clair Ridge, in UKCS Block 206/8, lies to the northeast of Clair Phase 1 and will be tapped with a pair of bridge-linked platforms–a drilling and production (DP) facilities platform and an accommodation and utilities (QU) platform.
