Polyester mooring ropes are highly engineered, critical components in deepwater oil and gas exploration and production. The Tahiti Spar deepwater mooring project called for the largest polyester ropes ever made. Lankhorst Ropes altered its production line to meet Chevron’s requirements. Among the requirements was a reduction in rope length tolerance, enhanced traceability, and recording of splicing. The production line alterations were carried out and the mooring rope produced on schedule. The authors describe the design requirements for the ropes and the methods used to produce them.
