Huisman to deliver crane for Green Jade

Huisman has been contracted by CSBC Corporation for the delivery of a 4,000 ton Offshore Mast Crane (OMC) to be installed on heavy lift vessel Green Jade. The crane will be built at a production facility in China and is scheduled for delivery in 2022.

With a lifting capacity of 4,000 tons at 125m above deck, and outfitted with specific auxiliary systems for handling tall structures, this high-tech OMC will enable the vessel to install the next generation of foundations and wind turbines. The crane is prepared for a super fly jib with lifting capacity and a whip hoist which allows lifting of smaller components up to a height of 185m above deck.

In addition to the main crane, Huisman will deliver a 65 ton Knuckleboom Crane for general lifting purposes. Both cranes will be installed and commissioned at the CSBC shipyard.

Huisman stated the crane combines a very large lifting height with a small footprint on deck. A large capacity for dynamic loads is required for high workability of the vessel continuously operating in diverse weather conditions. The small footprint comes with a small minimum radius, which leaves a maximum amount of space for project cargo.

A crane with such lifting height impacts the vessel’s stability because of the large weight of the crane and the high centre of gravity. This impact is minimised by the Mast Crane concept, whereby the winches are located at deck level instead of at the level of the slew platform.

Anne de Groot, Project Director at Huisman: “We are very pleased with the confidence shown in Huisman by awarding us this contract. We are committed to deliver value adding assets to CBSC and its partners for the installation of future generation offshore wind turbines.”

Green Jade will be operated by CSBC-DEME Wind Engineering (CDWE) which took the Final Investment Decision (FID) for the construction of the vessel last month. She will be built at CSBC in Kaohsiung and is set to be delivered in 2022. At 216.5m long, the vessel will be able to accommodate a crew of up to 160 people.

EPCI contractor CDWE was established in February 2019 and is a joint venture of CSBC, one the largest shipbuilders in Taiwan, and European marine contractor DEME Offshore.

In October last year, CDWE signed a large-scale Balance of Plant (BOP) Preferred Supplier Agreement with the Hai Long Offshore Wind Project. This was followed by the signing of two contracts with Zhong Neng Wind Power Corporation Preparatory Office for the 300 MW Zhong Neng offshore wind farm project. The contracts comprise the transportation and installation of foundations, as well as a Preferred Bidder Agreement for the transportation and installation of the wind turbines. CDWE stated that Green Jade will be deployed on both projects.
