From Concept to First Project
KNVTS Afdeling RotterdamThursday 26 September 2019Speaker: Sipke Schuurmans, Project Director SSCV Sleipnir, Heerema Offshore Services
Semi-Submersible Crane Vessel “Sleipnir”, the world’s largest and most sustainable heavy lift vessel, sailed away in July from Sembcorp Marine’s Tuas Boulevard Yard in Singapore to execute its first installation project in Israel. Sleipnir is equipped with two 10,000 mT cranes, built by Huisman.
The journey of constructing Sleipnir started in 2012, when Heerema started to develop the first concept designs of Sleipnir. During the design process, a number of innovations were integrated into the designs of the vessel and cranes, which will be presented. 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. 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, castings for the crane hooks had to be made with weights in excess of 200 mt, which proved to be very challenging. 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.
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.
