Imagine the costs of a project like this. SLEIPNIR is ready to lift a complete offshore deck. It’s cold, the ocean may be angry, calm or something in between. We test, we guard quality, and we test again. Multiple demands need to be orchestrated from many angles. We find answers for ever so many questions the shipyard fires at us. Safety regulations, striving for structural cost reduction and protection of marine biology. Then we start consultations with the client and the shipyard. Hundreds of documents and numerous drawings.

How to build a heat system for an LNG driven vessel this size? First we read.

A journey that we made together with Heerema Marine Contractors and Sembcorp Marine Shipyard. A special project like this starts with basic engineering and evolves gradually in customisation to the production of a unique hot water system. Nevertheless, it takes a scavenger hunt to find them on the SLEIPNIR. With a weight of 12,500 kilo per boiler, height 2,5 metres, length 7,5 metres and diameter of 2 metres they are not exactly petite boilers. Heatmaster built two hot water boilers for Sleipnir. The vessel stands out as the world’s first crane vessel with dual-fuel engines running on Marine Gas Oil (MGO) and Liquefied Natural Gas (LNG). With extended cranes the vessel is more than 85 metres taller than the London Eye. Two heavy-lifting offshore cranes, each with 10,000 tonne lifting capacity. You can’t begin to grasp it until you have actually witnessed the size and strength of this massive ship that is equipped for commissioning and decommissioning in the offshore oil-, gas- and windenergy industry. Named after the Norse eight-legged legend: SLEIPNIR, this vessel is the strongest and biggest of all crane-vessels in the world. A jaw dropping strong and big semi-submersible vessel, ordered by Heerema Marine Contractors (Leiden, The Netherlands). The largest dual-fuel crane vessel in the world. During the last four years you could see it materialise, almost like a mirage, levitating above every conceivable expectation.
