LANCASTER, UK – Retrieval and pull-in of a submerged turret production (STP) buoy is complete at the Maersk Peregrino FPSO offshore Brazil.
In 100 m (328 ft) of water, Peregrino field is in Campos basin block BM-C-7. The buoy is held in place by 10 mooring lines, each attached using Ballgrab mooring line connectors. For this job, a male Ballgrab connector connected to the female connector within the top of the buoy.
Prior to the FPSO arrival, the male Type III Ballgrab (MBL 1,200 metric tonnes), attached to the pull-in rope, was lowered into the female connector on the STP buoy by the installation vessel Maersk Attender. Once the FPSO was in position, the buoy, held 22 m (72 ft) below the surface, was pulled into the vessel's mating cone module. With the STP buoy locked in position, the FPSO is permanently moored at its location.
The Peregrino buoy pull-in shows the Ballgrab connector as the buoy enters theMaersk Peregrino FPSO's moonpool.
