World’s largest crane vessel put to the test

‘Sleipnir’, Heerema Marine Contractor’s newly launched semi-submersible crane vessel and the world’s first LNG powered Construction Vessel, has successfully completed her sea trials and crane load tests.

Sleipnir’s speed was tested and when fully deploying all eight thrusters, a speed was reached of 12.2 knots, approximately 22.6km per hour, significantly reducing transit times 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 colours.

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 her maiden voyage to southern Spain where she will be prepared for her first installation project in the Mediterranean.
