This is the first use of polyester ropes for a spar based floating production system and a first for a permanent mooring system in the Gulf of Mexico, said Marlow.
The milestone contract is another world record for Marlow Ropes which has pioneered the manufacture of synthetic deepwater tethers.
The Mad Dog spar, moored in 1.34km water depth with an 11 taut leg system, will employ Marlow Superline polyester ropes.
"With a design minimum spliced breaking strength of 1752 tonnes, these polyester ropes will have the highest strength ever produced for deepwater mooring. The major rope segments, together with spares and test insert pieces, total nearly 25.6km and will be delivered into the Gulf of Mexico by October 2003," the company said.
