Dutch contractor Heerema is preparing its massive new crane vessel Sleipnir for its first ever voyage.

Sleipnir has two cranes capable of lifting 10,000 metric tonnes each and a deck area 220 metres long, making it the “largest and strongest” semi-submersible of its kind in the world.

Constructed in Singapore, and passing sea trials earlier this month, the vessel will take on its first voyage this week.

It will set course for Spain in a journey which is expected to last 45 days, rounding South Africa’s Cape of Good Hope along the way.

Sleipnir also runs on magnesium oxide and liquefied natural gas, which Heerema said significantly reduces carbon emissions.

Chief executive Koos-Jan van Brouwershaven, said: “Not only is Sleipnir the world’s largest and strongest vessel, it is also first of its kind as far as sustainability goes.

“We are making offshore history. No other vessel has such numerous features. Our LED lights and shore power electricity are only a few examples of Heerema’s ambition in this area. Sustainability is an integral part of HMC’s identity, embedded in our daily work practices.”
