Heerema’s newest semi-submersible completes sea trials, systems tests

Sleipnir, Heerema Marine Contractors’ newest semi-submersible crane vessel and the world’s first LNG-powered construction vessel, has successfully completed sea trials and crane load tests.

Tests were conducted on all of the major systems including its two 10,000-tonne revolving cranes. A speed of 12.2 knots was reached when all eight of the vessel’s thrusters were fully deployed.

Sleipnir will soon commence its maiden voyage to southern Spain where it will be prepared for its first installation project in the Mediterranean.
