Huisman heavy lifting expertise for Subsea7

The fully electric crane will be installed on one of Subsea7’s pipelay vessels and will be deployed for deep water installations.

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

Active heave

The 500mt OMC 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 has upgraded its heave compensation system with a variety of new control modes to extend the operational window.

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.

Cranes are renowned for being lightweight, built up from high tensile steel, eliminating the need for ballast weight. Furthermore, the exceptional height of the mast provides a superior load curve.

Huisman Mast Cranes have been used within the industry for over 30 years and have become a standard in the design and construction of heavy lift cranes.

The company boasts a track record of nearly 50 OMCs successfully deployed for offshore construction and ultra-deepwater operations, reaching depths of up to 5,000 metres.

Subsea7’s new crane will be built in Huisman’s production facility in Schiedam, the Netherlands.
