Cargotec’s MacGregor has developed technology for handling lightweight fiber rope and is about to install the world’s first subsea crane to use fibre rope In January.

MacGregor is delivering the world’s first subsea knuckle-jib crane equipped with a system for fibre rope handling, which will be installed on the subsea vessel Havila Phoenix. The 250 tonne Hydramarine active heave-compensated (AHC) offshore crane is designed with a 250 tonne/3,000m single-line winch and is prepared for a 250 tonne single-line fibre rope. 

“MacGregor’s technology for handling lightweight fibre rope rather than traditional steel wire rope offers several advantages that will meet the ever-increasing demands of the offshore industry as operators move further into deeper and more remote territories,” said Øystein Bondevik, sales director in MacGrefor's Offshore division. “For example, due to the neutralisation of the weight of the fibre rope in the water, much heavier loads can be handled without strain to the crane at unlimited depths. Consequently, overall safety is improved due to the lighter equipment, which can still carry out heavy work operations.”

“The new generation of MacGregor Hydramarine subsea technology with operational capacity of up to 600 tonnes at depths down to 10,000m ensures indispensable precision, efficiency and safety in extreme conditions during year-around operations,” Bondevik said.
