Offshore rope manufacturer Lankhorst Ropes has been awarded a contract by Hyundai Heavy Industries and Technip USA consortium (HHITECH) to supply the mooring lines for Statoil’s Aasta Hansteen Spar platform to be located in the Norwegian sector of the Norwegian Sea. According to Lankhorst, it is the largest single order for deepwater mooring ropes, and believed to be the largest ever order in the global synthetic fiber rope industry.
Located in the Aasta Hansteen field, approximately 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 a water depth of approximately 1,300 m. Lankhorst Ropes is supplying 36 rope lengths totaling over 43,000 meters of Lankhorst’s Gama 98 polyester deepwater mooring rope with minimum breaking strength of 1,905 T (4,200 kips).
Integral with the rope construction is a cut resistant jacket (based on Dyneema fiber) developed by Lankhorst Ropes to meet Statoil’s stringent requirements to minimize the potential damage of trawl wire impact.
The Gama 98 ropes will be manufactured at Lankhorst’s state-of-art factory, dedicated to the production of offshore mooring systems, in Viana do Castelo, Portugal. Delivery is scheduled for first quarter 2015.
Aasta Hansteen Spar Platform
The Aasta Hansteen Spar platform will be the first Spar in Norwegian waters, the first Spar concept chosen by Statoil and the largest ever built with a total hull length of 198 meters.
The Aasta Hansteen field is a green field development and will host tiebacks from the Aasta Hansteen, Haklang, and Snefrid South fields. Statoil serves as the operator, holding a 75% interest; OMV holds 15%; and ConocoPhillips 10% interest.
