Offshore rope manufacturer, Lankhorst Euronete Brasil (LEB), has been awarded a contract by OOGTK Libra GmbH & Co KG to supply the Polyester Mooring Ropes for a Floating Production, Storage and Offloading (FPSO) unit in the Libra oil field, a large ultra-deepwater oil prospect located in the Santos Basin, 143 miles (230 km) off the coast of Rio de Janeiro, Brazil.
The FPSO will be moored at 7,900 feet (2,400 m) water depth by means of an external cantilever turret comprising nine mooring lines, arranged in 3 groups of 3 mooring lines each (3 x 3 clusters). Each mooring line will consist of 4,000m long hybrid chain-fibre rope-chain line. In total Lankhorst is supplying 58,800m of Cabral 512 Deep Water Polyester Mooring Rope with a minimum breaking strength of 12,300 kN.
The mooring system is designed as a taut catenary system, where each mooring line is connected to the FPSO via a chain stopper at its upper end, and to a torpedo pile through a pile shackle at the lower end.
