and tensioning. The rope took quite a beating, but fnished the job without failure. Once the Kwame Nkrumah was secured in place, the Turbo-EPX rope was reinstalled on the winch and ready to pull in the risers.

Only one of the three Turbo-EPX lines was used to pull the 11 risers.

According to one Technip installation engineer, the rope was still in good shape after the job was complete.

These examples demonstrate how synthetic ropes can replace steel-wire ropes, creating more effcient and safer operations. One of the barriers to using synthetics can be initial cost. Synthetic ropes can be 2-4 times more expensive than wire rope.
