RIO DE JANEIRO -- Installation is complete for the mooring line connectors at the Peregrino field submerged turret production (STP) buoy offshore Brazil, according to supplier First Subsea.
The mooring system for the STP buoy, in 100 m (328 ft) of water in block BM-C-7 in the Campos basin, comprises 10 mooring lines arranged in three clusters anchored to the seabed.
These lines each consist of a driven pile and bottom chain attached to a spiral strand wire segment and a male Ballgrab mooring line connector. Each male connector was connected by an ROV to female connectors mounted around the side of the buoy.
APL has supplied the STP buoy and mooring system, which will be linked to Peregrino’s turret-moored FPSO, owned and operated by Maersk.
On arrival of the FPSO at the field, the STP buoy will be pulled in using a male Ballgrab buoy pull-in connector tool. This will be lowered into a female connector integrated within the top of the 600-metric ton (661-ton) STP buoy, pulling the buoy into the vessel integrated mating cone module.
Once the STP buoy has been pulled in and locked, the FPSO will be permanently moored.
