July 11, 2019. Sleipnir, Heerema Marine Contractor’s semi-submersible crane vessel and the world’s first liquefied natural gas (LNG) powered construction vessel, is set to embark on its maiden voyage from Singapore.

Sleipnir, which completed its sea trials and crane load tests last month, is set to leave Singapore this week and start its 45-day trip towards Spain.

The vessel itself is designed to work on large offshore projects such as installing and removing jackets, topsides, deep-water foundations, moorings and other offshore structures, such as wind turbines.

This is the largest crane vessel ever built with a pair of world’s strongest revolving cranes and is the first vessel of its kind with dual-fuel engines running on MGO and LNG.

The last two days of LNG bunkering took place 12 miles off the coast of Indonesia with Heerema being the first company to perform LNG bunkering in this area of the world. Heerema selected Dutch company Titan LNG to help in this operation.

For this purpose, Titan LNG chartered a ship commercially managed by Dutch shipping firm Anthony Veder.

Sleipnir will now set sail for Spain, rounding South Africa’s Cape of Good Hope. In the Mediterranean, Titan LNG will again supply Sleipnir with LNG using the Coral Fraseri that will pass through the Suez Canal.

The vessel is equipped with two 10,000-tonne revolving cranes which can lift loads of up to 20,000 tons in tandem. During the recent sea trials, the cranes managed to lift loads of 11,000 tons per crane – 110% of its capacity.
