Huisman's 5000 mt Offshore Mast Crane, fitted aboard 'Seven Borealis' nominated for Innovation of the Year award.
Huisman, the specialist in lifting, drilling and subsea solutions, successfully delivered world’s largest Offshore Mast Crane onboard the Seven Borealis. The crane, with the top of the mast reaching 150 m above the main deck when in upright position, features a full heave compensated deepwater lowering system which will make it an efficient tool for the installation of heavy loads required for deepwater subsea production systems.
The 5,000 mt crane was installed, commissioned and load-tested at Sembawang Shipyard in Singapore. Besides the two 2,500 mt main hoisting blocks the crane has a 1,200 mt auxiliary hoist which is equipped with an active and passive heave compensation system and is capable of storing up to 6,000 m hoisting wire. The tip of the fly jib has an additional 110 mt whip hoist. The total installed motor power is approximately 15 MW. The crane revolves on an in-house designed and fabricated slew bearing with a diameter of 11 m. The crane provides unique features that enable unparalleled services.
Huisman’s 5000 mt Offshore Mast Crane aboard Subsea 7’s flagship and strategic enabler Seven Borealis has been nominated for the Innovation of the Year Award. The award winner will be revealed during the Annual Offshore Support Journal Conference on 19-20 February in London.
