The vessel stands at 220 meters long, 102 meters wide, is able to welcome 400 employees, and weighs 119,000 tons. As equally impressive as its mythical namesake, the vessel has already broken lifting records for crane vessels with a 15,300 lift in September 2019.

The vessel is equipped with two cranes onboard, each capable of lifting 10,000 metric tons. Therefore, it  is able to conduct the largest offshore jobs, such as building wind turbines at sea, dismantling old platforms, or constructing the most significant offshore structures.


Moreover, the vessel includes two large streamlined floats, which make it sail relatively quickly (on average, twenty kilometers per hour) with limited fuel consumption. What is especially unique about Sleipnir is that it has 'dual fuel' propulsion and can, therefore, run entirely on the emission-reducing fuel LNG.

The port states that Heerema is investing in sustainable measures, such as it's latest project concerning trialing alternative fuels on Thialf, a semi-submersible crane vessel with a 14,200 metric ton lifting capacity.

It is highlighted that

To protect the health of Heerema’s onboard crew during the COVID-19 (coronavirus) outbreak, no visitors are permitted to visit the vessel.

Sleipnir will call the port, after a project in Trinidad. The vessel arrives to prepare for future decommissioning work across the North Sea. By using Sleipnir, Heerema is working on cleaning up retired drilling platforms in the cleanest possible way with their use of emission reducing LNG. The vessel is due to depart at the end of March for the first of several jobs.
