Constructed in 2019 by
Constructed in 2019 by Sembcorp Marine in Singapore, SSCV Sleipnir is considered the biggest crane ship in the world.
It is owned and operated by Heerema Marine Contractors and has 2 revolving cranes with a lifting capacity of 10,000 tonnes each, totalling 20,000 tonnes when both cranes are operated alongside each other.
The largest crane vessel is like a massive platform that has 8 columns, four on each side and one pontoon per side.
Conventional SSCVs have bigger columns under cranes to offer support but it leads to severe pitching in rough waters whereas SSCV Sleipnir has symmetrical columns, providing for calmer motions during rough weather conditions at sea.
Additionally, the columns are round to decrease wave impact and the pontoons are streamlined to offer drag reduction.
The vessel’s LNG storage and ballast tanks are present in the 8 columns, each 23.7 m high with a staircase linking the deck with the pontoon below.
