How can we help you?

The world's largest semi-submersible crane vessel Sleipnir will arrive in the Port of Rotterdam for the first time on Sunday, March 22. Sembcorp Marine, a Singaporean ship and offshore builder, completed the construction of Heerema's Sleipnir in July 2019. Since then, the vessel has been busy across the globe.


Named after the Norse God Odin's eight-legged stallion, the vessel stands at 220 meters long, 102 meters wide, can accommodate 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 semi-submersible vessel has two cranes onboard, each capable of lifting 10,000 metric tons. This ability makes it suitable for the largest offshore jobs, such as building wind turbines at sea, dismantling old platforms, or constructing the most significant offshore structures.


Due to Sleipnir's two large streamlined floats, the vessel can 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.


Heerema actively invests in sustainability measures, most recently trialing alternative fuels on Thialf, a semi-submersible crane vessel with a 14,200 metric ton lifting capacity. Alongside, the ongoing Shore Power Caland Canal project in collaboration with Eneco to provide 100% renewable energy to Heerema vessels that moor in the Port of Rotterdam.

Sleipnir arrives following a successful project execution in Trinidad, having already worked in Brazilian and Israeli waters. 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.

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