Offshore rope manufacturer Lankhorst Ropes has been awarded a contract by HHITECH (Hyundai Heavy Industries and Technip USA consortium) to supply the mooring lines for Statoil’s Aasta Hansteen Spar platform.
The platform is destined for the Norwegian Sea. Lankhorst says the order will be the largest single order for deepwater mooring ropes, and it believes it is the largest order in the global synthetic fibre rope industry.
Located on the Aasta Hansteen field, about 300 km west of Bodø, the Spar platform will be moored with 17 polyester mooring lines in groups of 6, 5, and 6 lines at about 1300m water depth.
Lankhorst Ropes is supplying 36 rope lengths, totalling more than 43,000m of Lankhorst’s Gama 98® polyester deepwater mooring rope, with minimum breaking strength of 1905 T (4200 kips).
Integral with the rope construction is a cut resistant jacket (based on Dyneema fibre) developed by Lankhorst Ropes to meet Statoil’s requirements to minimize the potential damage of trawl wire impact.
The Gama 98 ropes will be manufactured at Lankhorst’s factory, dedicated to the production of offshore mooring systems, in Viana do Castelo, Portugal (pictured). Delivery is scheduled for Q1 2015.
The Aasta Hansteen spar platform will be the first spar in Norwegian waters, the first spar concept chosen by Statoil, and the largest spar built with a 198m total hull length.
The Aasta Hansteen field is a greenfield development and will host tiebacks from the Aasta Hansteen, Haklang, and Snefrid South fields.
Statoil is the operator, holding a 75% interest; OMV holds 15%; and ConocoPhillips 10% interest.
