![]() ![]() 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). 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. It is armed with the strongest pair of revolving cranes for offshore oil, gas and renewable energy installation and decommissioning jobs. The world’s biggest semi-submersible crane vessel (SSCV) has a 220-metre by 102-metre reinforced deck area, making it the largest crane vessel to be built. We are eager to inform you about the possibilities.Sembcorp Marine has finished construction of the SSCV Sleipnir for owner Heerema Marine Contractors. Would you like to get more information about our HVAC solutions for crane vessels? Don’t hesitate to get in touch. As a result, the systems are fully customized to meet the strict offshore requirements. The HVAC system is based on the following design conditions: Summer conditionsĪll relevant systems are installed in compliance with LRS, NMA, DSB, USPH, NIPH, Lloyds ECO/notation and Eurovent, where applicable. In total, 285.000 man-hours were utilized in a period of 36 months to complete the project. The main challenge was the collaboration between the client, shipyard and equipment suppliers in the various integration phases to complete and handover the project within the project schedule. This translates into a higher system efficiency which lowers the operational costs. All the pumps are variable speed controlled which regulates the pump speed according to the systems demands. Next to that, a variable primary flow (VPF) system is adopted for the chilled water system. To meet the requirements, each air handling unit is equipped with an enthalpy wheel to recover waste energy. The HVAC system had to be energy-efficient, work fully automatic and operate safe while meeting the strict offshore requirements. Heinen & Hopman supplied the HVAC system, which consists of six different zones that comprises of twelve chillers serving twenty-two main air handling units. The vessel is also the first dual-fuel crane vessel, with engines running on MGO and LNG for sustainable operation across all environmental jurisdictions. The vessel can accommodate up to 400 persons and will be deployed by Heerema Offshore Services for installation and decommissioning of major offshore facilities worldwide. Sleipnir is a new-generation semi-submersible crane vessel with two revolving cranes that each can lift 10.000 tonnes and 20,000 tonnes in tandem – no other existing crane vessel has this capability. Sleipnir is legendary for its strength, courage and speed. It is named Sleipnir, after Odin’s eight-legged stallion from the Norse mythology. The vessel is 220 meters in length, with a width of 102 meters, constructed by Sembcorp Marine. Heinen & Hopman Singapore has, with support from Heinen & Hopman Headquarters, successfully delivered the HVAC system for world’s largest semi-submersible crane vessel.
