Babcock is to manufacture and deliver over 70 subsea structures as part of the major Quad 204 offshore redevelopment project, some 130km west of Shetland, UK, under a £30m+ contract awarded by BP.

The complex and highly technical Quad 204 project consists of a new Floating Production System Offshore (FPSO) to replace the existing Schiehallion FPSO; an extension of the existing subsea system with 15 new or replacement flow lines and 21 new or replacement risers; and 14 new wells in addition to the 52 existing wells. This major project will access the remaining hydrocarbon reserves in the Schiehallion and Loyal fields, extending production through to 2035.

Under the contract Babcock will be fabricating 74 modules in carbon steel for the subsea system. These include 44 process fluid handling structures (including manifolds, flowline and riser terminations, and subsea isolation valve structures), and 30 control distribution structures (such as assemblies and umbilical terminations), amounting to a total of some 2,300 tonnes of fabrication.
