FPSO HYSY113 Tower Yoke
Scope of Work
SOFEC designed and procured a tower yoke mooring system for the HYSY113 FPSO.
The FPSO, named HYSY113, is deployed in the BZ25-1/S field approximately 150 kilometers southeast of the Port of Tanggu in Bohai Bay and is a replacement for a previously operating mooring system.
The tower yoke mooring system is an interface between the BZ25-1/S wells and the FPSO and will provide for the transfer of well fluids, water injection and provide Medium Voltage power to the well head platforms.
