Heerema's Sleipnir Passes Sea Trials with Flying Colors
Sleipnir, Heerema Marine Contractor’s newest state-of-the-art semi-submersible crane vessel and the world's first LNG powered Construction Vessel, has successfully completed her sea trials and crane load tests.
During Sleipnir’s sea trials all major systems performed according to specifications or even better:
Sleipnir’s speed was tested and when fully deploying all eight thrusters, a speed was reached of 12.2 knots, approximately 22.6 km per hour, significantly reducing Sleipnir’s transit time to projects around the world.
The vessel’s two 10,000-tonne revolving cranes which can lift loads of up to 20,000 tonnes in tandem, were also put to the test. Being the largest crane vessel in the world, Sleipnir can lift huge loads and the tests showed she can easily meet the cranes’ specifications. Operational tests were carried out successfully with loads of 11,000 tonnes per crane (110% of its capacity) and the cranes passed the tests with flying colors.
The Dynamic Positioning system performed even better than the specifications and the system can keep Sleipnir stationary within the footprint of a garden tile of 30 x 30 cm during operational work.
Sleipnir will soon commence its maiden voyage to southern Spain where it will be prepared for its first installation project in the Mediterranean.
Heerema Marine Contractors has signed a new contract to support the construction of a wind farm project, this time in Taiwan. Assigned by the Taiwan branch of Jan de Nul, Heerema will take on the installation of 21 jacket foundations (4 legged) for the Changhua project. The Changhua Taiwan Power Company Windfarm Phase 1 project is situated in Taiwanese waters and is a project of the Taiwan Power Company (TPC) and executed by a consortium of Jan de Nul and Hitachi. The installation will take place 8 km off the coast of Changhua county, at a water depth of 18 to 28 meters.

This week, Heerema’s newest vessel Sleipnir will begin her maiden voyage. Sleipnir, the world’s largest and strongest semi-submersible crane vessel (SSCV) was built in Singapore and will set course for Spain. The trip will take about 45 days. This unique vessel is the largest crane vessel yet built. It has the strongest pair of revolving cranes and also is the world’s first crane vessel with dual-fuel engines running on MGO and LNG, dramatically reducing harmful emissions.The last two days bunkering of LNG took place 12 miles off the coast of Indonesia. Since LNG is not yet obtainable worldwide, Heerema is the first to perform an LNG bunkering in this area of the world. Heerema has selected Dutch company Titan LNG to help in this undertaking. Titan LNG has chartered a ship commercially managed by Anthony Veder, also Dutch, thus resulting in a unique Dutch cooperation.
