Fibre rope crane (FRC)

Working better deeper. The new fibre rope crane with a range of up to 400t is designed for continuous operation in a tough and corrosive offshore environment with focus on efficient and safe load handling.

A range of offshore cranes up to 400 tonnes load using field proven fibre rope handling technology is now launched. The crane structure has an integrated operator cabin and the fibre rope runs over large diameter sheaves. Below deck is a compact CTCU (cable traction control unit) which forms the crane winch, provides active heave compensation and stores the rope on a reel. This system has a proven track record of more than 10 years. Particular attention has been made to ease of access and maintenance of all main components.

Because the selected rope has neutral buoyancy, the crane can handle loads to its full rated capacity down to 4,500 metres water depth. Cranes using heavy steel wire must begin derating at depths more than about 700m, so by 2,500m a 400t wire crane can only handle the same load as a 250t FRC.

Our rope management system monitors rope condition enabling abraded or damaged sections to be easily repaired by splicing onboard.
