Huisman has been contracted by CSBC Corporation to deliver a 4,000-tonne offshore mast crane for the heavy lift vessel Green Jade
The vessel is being built for a joint venture, CSBC-DEME Wind Energy (CDWE), who will operate the vessel in the Taiwanese offshore wind market.
The crane will be built at the company’s production facility in China and is due for delivery in 2022.
With a lifting capacity of 4,000 tonnes 125 m above deck and outfitted with auxiliary systems for handling tall structures, the crane will enable Green Jade to install the next generation of foundations and wind turbines.
The crane is prepared for a super fly jib with significant lifting capacity and a whip hoist which allows smaller components to be lifted up to a height of 185 m above deck.
In addition to the main crane, Huisman will deliver a 65-tonne knuckleboom crane for general lifting purposes.
Huisman said its crane combines lifting height with a small footprint on deck. The small footprint comes with a small minimum radius, which leaves the maximum amount of space for project cargo.
A crane with this kind of lifting height has an influence on a vessel’s stability because of the weight of the crane and its high centre of gravity, but this impact is minimised in the mast crane, in which the winches are installed at deck level instead of at the level of the slewing platform.
In June, Riviera held a series of webinars on offshore wind. These are available to view in our webinar library
