Huisman has recently been awarded a contract by Subsea7 for the delivery of a 500 metric-ton offshore mast crane. The crane, which will be fully electric, is going to be installed on one of Subsea7’s pipelay vessels and will be used for deep water installations.

The 500 mt Offshore Mast Crane will be equipped with a passive and active heave compensation system on the main hoist to counter-act the vessel’s heave motion when landing a product onto the seabed. Huisman has upgraded its heave compensation system with a variety of new control modes to extend the operational window.

The crane will be built in Huisman’s production facility in Schiedam, the Netherlands.

“We are delighted to announce this contract of our valued client, Subsea7. Our pursuit of continuous improvement has led to the upgrade of our Offshore Mast Crane to an impressive 500mt, showcasing our dedication to innovation and client satisfaction,” David Roodenburg, CEO of Huisman said.

The small rectangular footprint of this crane allows for easy integration with the vessel’s steel structure and direct installation of the crane on the stern, achieving a large effective outreach and reducing integration costs.
