Huisman to build 4,000-tonne crane for Boskalis

Dutch crane and offshore engineering specialist Huisman will supply a 4,000-tonne crane for Royal Boskalis Westminster N.V.

The offshore mast crane will be installed on the Boskalis vessel Bokalift 2, currently under construction. It follows Huisman’s delivery of a 3,000 tonne OMC for Bokalift 1 in 2017.

The 4,000-tonne capacity is available up to 100 metres above the deck which allows wind turbine jackets to be lifted off it. Adding the fly jib allows smaller components to be lifted 125 metres above the deck. Monopiles and other long loads can be upended from horizontal to vertical.

Huisman designed its OMC to have a small footprint and no tail swing, maximising space on deck for payload. Its capability will future proof it for installing current and future generation offshore wind turbine foundations. In addition, it should find work in offshore oil and gas, decommissioning and salvage.

Royal Boskalis Westminster N.V. (Boskalis) has announced their involvement in a new offshore wind project off the coast of Taiwan on 29th October 2019. Together with Taiwanese partner Hwa Chi Construction Co. Ltd. they have been awarded the foundation scope for the Taiwanese Changfang and Xidao offshore wind farm (CFXD OWF) project owned by Copenhagen Infrastructure Partners (CIP). The project includes the transportation and installation of sixty-two three-legged jacket foundations and the accompanying 186 pin piles. The contract value for Boskalis is substantial (For Boskalis, a “substantial” contract is between EUR 150 million and EUR 300 million) and is subject to financial close of the CFXD OWF project by CIP due later this year.

CFXD OWF will be the launching project for the new Bokalift 2 crane vessel. Similar to the successful Bokalift 1, Boskalis will convert an existing hull to create the Bokalift 2 crane vessel. The DP2 vessel with accommodation for 150 persons will boast 7,500 m2 of free deck space and a 4,000t revolving crane capable of lifting structures more than 100 meters high. The Bokalift 2 will be a flexible value-adding asset, well-positioned for the installation of current and future generation offshore wind turbine foundations as well as oil and gas structures in addition to serving the decommissioning and salvage market.
