From individual components to complete turnkey packages, Lankhorst’s and OIL’s experience and reputation for excellence positions them at the forefront of today’s offshore specialists. Weak Links Weak links, if fitted, should be selected such that the recommended bow chain stopper, chafe chain, hawser or connection to the SPM do not constitute the weakest yield strength of MBL component of the entire system. Weak links, if fitted, should be designed, manufactured and tested under a certification scheme. Support Buoys When the berth is...

l.ankhorst Ropes HAWSER DATA - DOUBLE BRAID CONSTRUCTION Rope with a braided sheath over a braided hollow core (also called 2 in 1 and Braidline). Material: NYLON Construction: Double braided ropes are constructed by braiding a sheath over a braided hollow core. They have 32 core strands and 64 sheath strands with an equal number of left and right hand providing a perfectly torque free rope. Double Braid is acknowledged as the best rope construction manufactured to absorb the enormous dynamic forces generated at SPM's. Manufactured, inspected and supplied in accordance with the OCIMF 2000...

OFFSHORE liinkhorst Ropes HAWSER DATA - GAMA 98® (PARALLEL STRAND) CONSTRUCTION Material: NYLON Construction: The GAMA 98® ropes are made from high efficiency sub-rope cores laid parallel within an outer braided jacket. Each sub-rope is computer monitored during manufacture to ensure all sub-ropes have equal tension and length. The GAMA 98® has become the industry standard for FPSO/FSO offtake mooring hawser arrangements. Manufactured, inspected and supplied in accordance with the OCIMF 2000 "Guidelines for the Purchasing & Testing of SPM Hawsers" GAMA 98® Nylon...

HAWSER DATA - ASTRALINE® 8-STRAND MULTIPLAIT CONSTRUCTION Rope construction of two pairs of stands with right hand twist and two pairs of left hand twist, braided together in such a way that pairs of strands of opposite twist overlay one another. ASTRALINE® Dia Size Weight NDBS NDBS Material: COMPOSITE YARNS (POLYESTER HIGH TENACITY / POLYVER] Construction: Astraline® is an 8-strand multiplait constructed rope, comprising of a polyver® core and a high grade polyester cover. This composite yarn has been proven to give excellent performance in resisting abrasion. Manufactured,...

HAWSER FLOTATION SPM Hawsers typically manufactured from nylon (SG 1.14) will not float naturally in seawater. A hawser which sinks will foul the catenary moorings of a CALM buoy or other subsea equipment. We have a range of flotation methods. • Lace-on hawser floats • Integral hawser flotation • Tubular floats Please ask us for detailed data sheets on the below flotation types. Lace-on hawser float The integrity of the mooring hawser depends on the floats sustaining hawser buoyancy. All our floats feature a double outer layer manufactured from high abrasion resistant ballistic...

Integral Flotation It has been reported by operators using mooring hawsers with conventional lace-on floats, that during the lifetime of the hawser the floats tend to suffer damage and can be ripped away from the rope. This can be costly to the operator having to secure replacement floats and organise maintenance crews to replaced damaged / missing floats. Our Integral Flotation system overcomes these issues, and in addition offers many other operational benefits. Mooring hawsers incorporating our Integral Flotation system are wrapped in closed cell buoyancy foam, ensuring sufficient...
