Goliat mooring lines restrict FPSO movement

Offshore staff

HAMMERFEST, Norway – Lankhorst Ropes Offshore has overseen installation of the mooring ropes for Eni’s Goliat FPSO, 85 km (53 mi) offshore northern Norway in license areas PL229 and PL229B in the Barents Sea.

The cylindrically shaped Goliat FPSO employs a semi-taut leg mooring system to limit movement of the vessel, due in part to local metocean conditions.

The mooring system comprises 14 Gama 98 polyester mooring lines configured in three clusters of four, four, and six lines in 400 m (1,312 ft) of water. Two clusters have longer mooring lines to provide the lateral restoring force needed to keep the production vessel on station.

To minimize potential damage caused by trawl wire impact, Lankhorst Ropes developed a trawler wire-resistant rope jacket for the polyester rope lines, and supplied buoyancy elements which are secured on elongated shackles, providing an uplift of 19 tons, in order to prevent the mooring lines from touching the seabed.
