Huisman to build 500 tonne offshore crane
22 January 2024
Dutch crane and engineering specialist Huisman has been awarded a contract from Subsea7 for the delivery of a 500 tonne offshore mast crane.
The fully electric crane will be installed on one of Subsea7’s pipelay vessels and will be deployed for deep water installations.
The 500 tonne offshore mast crane will be equipped with a state-of-the-art 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 said.
Huisman has upgraded its heave compensation system with a variety of new control modes to extend the operational window.
The crane will be built using high tensile steel in Huisman’s production facility in Schiedam, the Netherlands.
David Roodenburg, CEO of Huisman said, “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 500 tonnes, showcasing our dedication to innovation and client satisfaction.”
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, Huisman said.
Huisman boasts a track record of nearly 50 offshore mast cranes successfully deployed for offshore construction and ultra-deepwater operations, reaching depths of up to 5,000 meters.
