ABERDEEN-- Advanced Production and Loading (APL) has awarded First Subsea a contract to supply mooring line connectors and a buoy pull-in connector for the FPSO Peregrino submerged turret production (STP) buoy.

The Peregrino STP buoy will be moored in 100 m (30 ft) of water, 85 km (53 mi) offshore Brazil. The FPSO is operated by Maersk FPSOs Brazil.

First Subsea is providing ten Ballgrab ball and taper connectors with a minimum breaking load (MBL) of 10,600kN for its 30 year life. The female Ballgrab connectors are attached around the side of the buoy ahead of tow out. Once in position the male Ballgrabs and mooring lines are connected subsea with assistance by ROV, avoiding the need for divers, the company says.

APL is also using a Ballgrab buoy pull-in tool to pull the 600-metric-ton (661-ton) STP buoy into the FPSO. The female part of the connector is integrated within the top of the STP buoy. Once the FPSO is in position, the Ballgrab male connector is lowered into the female connector on the STP buoy, locked into position, and the buoy pulled into the FPSO's mating cone.
