Abstract
An arrangement for laying non-rigid product offshore that includes a dual long grip length clamp arrangement installed vertically into a tower in a similar manner to a J-lay trolley/clamp system. The invention differs from a J-lay arrangement in that two clamps are used and the clamps are configured for use with non-rigid product, i.e. they have a long grip length in order to spread the load evenly. Each clamp is mounted on a trolley and can travel vertically up or down. The upper clamp is arranged with a distance between it and the lower clamp such that the upper clamp can lower the non-rigid product a suitable distance before the lower clamp grips the non-rigid product so as to create as close as possible continuous movement as practical.
