Norway based Offshore Heavy Transport (OHT) teams up with Dutch design company Ulstein Design & Solutions to build a new heavy lift transport and installation vessel.
The first vessel (with options for up to another 3 units) will be constructed by China Merchant Heavy Industry (CMHI) and available for construction and installation activities from early 2021.
What makes this dynamically-positioned, 48,000 DWT vessel exceptional, is the ability to perform heavy lift crane operations with the main deck submerged. The patent-pending design combines the benefits of a semi-submersible transport vessel with a large, 3,000 mt lifting capacity main crane from Liebherr.
The vessel’s capabilities match the future requirements of the offshore wind industry, allowing her to transport and install upto 10 x 1,500t ultra-large jacket foundations or 11 x 2,000t XXL monopiles plus transition pieces for the largest anticipated Wind Turbine Generators.
