bp has handed the Subsea Integration Alliance responsibility for the Murlach Field (ex-Skua) development in the UK central North Sea, 240 km east of Aberdeen.
The EPCI work scope covers installation of the subsea pipelines (SURF) and subsea production systems (SPS), the latter marking the first deployment of OneSubsea’s standard, configurable, vertical monobore tree systems in the UK North Sea. Both will be deployed from a vessel to reduce drill rig days, said partner Subsea7.
Altogether, OneSubsea will provide two vertical monobore trees, a two-slot manifold and associated topside controls for the host ETAP platform.
According to Subsea7, the Subsea Integration Alliance worked with bp to develop a solution using OneSubsea’s field-proven standard equipment, said to be simpler to design and faster to install than traditional "configured-to-order" subsea systems.
Subsea7 will install 8 km of rigid flowline, tied back to ETAP, along with two flexible jumpers and associated subsea infrastructure. The company will fabricate the pipes at its spoolbase at Vigra, Norway, and expects to perform offshore operations during 2025.
This is bp’s third fully integrated EPCI project with the alliance.
