Heerema has already secured contracts to deploy the vessel in various offshore energy developments, including: Leviathan topsides installation in the Mediterranean Sea Tyra jackets and topsides installation and removal in the Danish North Sea Brae B jackets and topsides removal in the UK North Sea as well as transportation and installation of the Hollandse Kust Zuid (HKZ) Alpha HVAC platform in the North Sea, off the Dutch coast. Coupled with an IMO- and US Coast Guard-approved ballast water management system, Sleipnir will operate sustainably across all environmental jurisdictions. The vessel further stands out as the world’s first crane vessel with dual-fuel engines running on Marine Gas Oil (MGO) and Liquefied Natural Gas (LNG). Importantly, with its single-lift capability catering to larger integrated structures than previously possible, Sleipnir will minimise offshore assembly work and raise operational efficiency to a new level, while not compromising the flexibility and robustness of traditional installation methodologies. Sleipnir can accommodate 400 persons and will be deployed globally for installing and removing jackets, topsides, deep-water foundations, moorings and other offshore structures. No other existing crane vessel has this capability. The vessel also has two 10,000-tonne revolving cranes which can lift loads of up to 20,000 tonnes in tandem. Named after the Norse God Odin’s eight-legged stallion and newly completed at Sembcorp Marine’s Tuas Boulevard Yard for owner Heerema Marine Contractors, SSCV Sleipnir has a 220-metre by 102-metre reinforced deck area, making it the largest crane vessel to be built. Singapore, – The world’s biggest semi-submersible crane vessel (SSCV) is set to blaze a trail when it enters into service in the coming months, armed with the strongest pair of revolving cranes for offshore oil, gas and renewable energy installation and decommissioning jobs.

The vessel is also the first dual-fuel crane vessel, with engines running on MGO and LNG for sustainable operation across all environmental jurisdictions.

SSCV Sleipnir is a new-generation semi-submersible crane vessel with a pair of revolving cranes that can lift 20,000 tonnes in tandem – no other existing crane vessel has this capability.

Note: To protect the health of Heerema’s onboard crew during the COVID-19 (coronavirus) outbreak, no visitors are permitted to visit the vessel.Sembcorp Marine completes world’s biggest and strongest semi-submersible crane vessel for Heerema The vessel is due to depart at the end of March for the first of several jobs. 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 arrives to prepare for future decommissioning work across the North Sea. Sleipnir arrives following a successful project execution in Trinidad, having already worked in Brazilian and Israeli waters. 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. 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. What is especially unique about Sleipnir is that it has ‘dual fuel’ propulsion and can, therefore, run entirely on the emission-reducing fuel LNG. Image Credits: Heeremaĭue to Sleipnir’s two large streamlined floats, the vessel can sail relatively quickly (on average, twenty kilometers per hour) with limited fuel consumption. 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. The semi-submersible vessel has two cranes onboard, each capable of lifting 10,000 metric 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.

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. Since then, the vessel has been busy across the globe. Sembcorp Marine, a Singaporean ship and offshore builder, completed the construction of Heerema’s Sleipnir in July 2019. The world’s largest semi-submersible crane vessel Sleipnir will arrive in the Port of Rotterdam for the first time on Saturday, March 21.
