In September we have a new location, De Machinist, for our lectures in Rotterdam. Location: De Machinist, Willem Buytewechstraat 45, Rotterdam. Special attention will be given to the LNG system, with which Sleipnir is equipped, and the challenges of bunkering LNG at the scale and locations required for Sleipnir. The vessel is equipped with two revolving cranes built by Huisman Equipment B.V. It is named for Sleipnir, the eight-legged horse ridden by Odin in Norse mythology. And despite the large dimensions and high weights, sometimes tolerances in the order of tenths of millimeters had to be respected when the crane parts were integrated into the hull. SSCV Sleipnir is a semi-submersible crane vessel (SSCV) owned and operated by Heerema Marine Contractors. Furthermore, castings for the crane hooks had to be made with weights in excess of 200 mt, which proved to be very challenging. For instance, 95,000 mt of steel had to be fabricated, 3000 km electrical cable had to be pulled and over 80,000 pipe spools had to be fabricated and installed. Furthermore, Heerema will provide an overview of the design and building process of the vessel and cranes, highlighting the challenges that had to be met in engineering, construction and commissioning. During the design process, a number of innovations were integrated into the designs of the vessel and cranes, which will be presented.

With a planned 165-turbines, Hornsea Two, located around 55 miles off the Yorkshire coast, will be the biggest offshore wind farm in the world when it becomes fully operational in 2022. HMC is expected to return to the development in 2021 to complete its scope. It brings to an end around two years of work between HMC, Ørsted, fabricator SMOE in Batam, and transportation subcontractor Biglift.

In August, the 1500 metric ton RCS jacket and 5000 metric ton OSS jacket set sail from Batam in Indonesia bound for the project site, a journey which took around 50 days. It follows the installation of the platform for the offshore substation (OSS) earlier this month. The Dutch-headquartered company’s Sleipnir offshore crane transported and fitted the foundations for the project’s reactive compensation station (RCS) platform in the Southern North Sea. Heerema Marine Contractors (HMC) has successfully completed jacket installations for Ørsted’s major Hornsea Two offshore wind farm development. Loading Spinner An icon of a loading spinner.
