HOUSTON – InterMoor reports that it has completed the tow and hook-up of the floating production unit (FPU) Argos.
InterMoor provided mooring engineering and offshore support for Subsea 7, the main contractor for the EPCI portion of the project on behalf of bp. The FPU was built for the Mad Dog 2 field in the deepwater Gulf of Mexico, in water depth of about 1,360 m.
Subsea 7, with InterMoor’s support, first performed the mooring line pre-lay, installing over 8,220 m of chain. The team then towed the FPU from Ingleside, Texas, to its final offshore site in the Green Canyon area, and hooked up the FPU to the pre-laid mooring lines using Island Offshore’s anchor handling vessel Island Victory.
InterMoor’s work scope also included equipment marshalling and dock services from their shore base in Fourchon, Louisiana.
The mooring system is a 12-point mooring system with three lines arranged in each corner of the FPU. Each mooring line consists of a suction anchor, a 171-mm R4S ground chain segment, two polyester rope segments, and a 171-mm R4S platform chain segment.
