The air-gas mixture will be sparked-off by high pressure MGO injection. Read more about Sleipnir's sustainability here. A double shell (1.50 metres) protects the outer areas, complying with rules for mobile offshore units. The ballast system is designed for control of draft and stability, as well as trim and heel during lifting operations at maximum load. Crew: up to 400 persons. The vertical LNG cylinder tanks are built-in within the column structures, taking into account dynamic forces as well as buoyancy forces resulting from possible compartment flooding. Sleipnir's scale is hard to imagine, standing at 220 meters long, 102 meters wide, with the room to accommodate 400 employees, and weighing 119,000 tons. Sleipnir was contracted to install a total of 38,000-ton of operational units. HMC has now chosen for smaller tanks for lifting assistance only.

The vessel also has two 10,000-tonne revolving cranes which can lift loads of up to 20,000 tonnes in tandem.

Sustainbility is a big part of Heerema’s responsibility and is an essential component of the company’s management philosophy on all levels.

A helicopter deck is mounted on the aft side of the deckhouse, along with check-in/out rooms. Today, on Sunday, March 22, we welcomed Sleipnir to The Netherlands. Sustainability is a strategic priority for Sembcorp Marine. Semi-submersible crane vessel (SSCV) Sleipnir is a large lifting ship owned and operated by Heerema Marine Contractors. Sleipnir can accommodate 400 persons and will be deployed globally for installing and removing jackets, topsides, deep-water foundations, moorings and other offshore structures. The ballast system is designed for control of draft and stability, as well as trim and heel during lifting operations. At its peak, the construction of Sleipnir involved up to 3,700 workers in a single shift. The vessel has dual-fuel engines that enable Sleipnir to run on LNG, drastically reducing harmful emissions. Heerema Marine Contractors' giant semi-submersible crane vessel Sleipnir has broken its recently set heavy lifting record with the removal of Shell's 10100 … The vessel will leave for sea trials shortly and is scheduled for delivery to Heerema soon afterwards. We know that from experience. When sailing, the Sleipnir can operate with various combinations of engine rooms and power generators.

The dual fuel engines are MAN 8L51/60DFs. The columns are rounded to reduce wave interactions, and the pontoons are streamlined to reduce drag.

Interconnecting LNG and gas lines are all double walled and made of stainless steel. Sleipnir’s innovative capabilities will place Heerema even firmer at the forefront of developments in the offshore oil, gas and wind energy industry for both installations and decommissioning.”, Mr Heerema added: “Sembcorp Marine in Singapore was chosen to build Sleipnir for their professionalism and dedication to the project. HMC’s vision on required crane capacity developed from 2 x 8000 to 2 x 10,000 tonnes, along with the need of a very large deck area of 12,000 m2. A symmetrical twin-pontoon semi-submersible with four columns on both sides, proved superior operability. Oops! [10] Cruising speed is rated at 10 kn (19 km/h; 12 mph). To download high-resolution images accompanying this press release, please click here. When submerged to operating draft, the hydrodynamic forces interacting on the hull parts result in minimum motion. [16], During sea trials, SSCV Sleipnir reached a speed of 12.2 kn (22.6 km/h; 14.0 mph).

Using the auxiliary hoist, objects can be lifted and lowered from 50 m (160 ft) below the waterline to 165 m (541 ft) above it when SSCV Sleipnir is operating at its maximum 32 m (105 ft) draft. No other existing crane vessel has this capability.

Other dimensions of the deckbox follow the requirements of the vessel arrangement. Wave loads are a major factor in the structural design of semi-submersibles. Nevertheless, it takes a scavenger hunt to find them on the SLEIPNIR. Sleipnir’s innovative capabilities will place Heerema even firmer at the forefront of developments in the offshore oil, gas and wind energy industry for both installations and decommissioning.” Mr Heerema added: “Sembcorp Marine in Singapore was chosen to build Sleipnir for their professionalism and dedication to the project. In DP3 mode, eight thrusters are operating at 75 per cent rating. Each switchboard feeds power to two of the eight thrusters and to one of the two slip rings per crane (fifty per cent of crane power).

In the last 7 months, Sleipnir has been involved in various projects, including: During this project Heerema’s SSCV Sleipnir set a new world record, completing a 15,300 tonnes lift, installing the topsides for Noble Energy’s Leviathan development in the Mediterranean.

The sturdy, rounded bow resembles the shape of large bulkcarriers with proven resistance characteristics. Check out the below video below for a helicopter and inside view of this amazing vessel: Projects Heerema’s SSCV Sleipnir, the world’s largest crane vessel, completed a 15,300 tonnes lift this weekend, installing the topsides for Noble Energy’s Leviathan development in the Mediterranean. Sleipnir ballasted down to 32 meters draft during sea trials, getting ready to mobilize to her first job This, however, couples the pitch and heave motions in long swells, altogether affecting vessel operability. Additionally, the vessel is fully outfitted with LED-lighting, has a hot/cold energy recovery system, and is ready to be powered by clean electricity when moored in the Caland Canal following the completion of the Shore Power project.

The transparency of a multi-column structure allows passing of waves with lesser wave breaking and refraction. A symmetrical twin-pontoon semi-submersible with four columns proved superior operability. Crane installation at Sembcorp Marine, Singapore.

The units are designed for a bollard pull of more than 1030 kN, but can also be used for steering and propulsion.

Heerema’s SSCV Sleipnir installed the jacket for the new Peregrino C platform.

The braces are structurally redundant, one extra to a pair.

The deepwell pump line and the boil-off line are connected here. Heerema Marine Contractors (HMC) is a world leading marine contractor in the international offshore oil and gas and renewables industry. Celsiusstraat 32

[20][21], In March 2015, Heerema Offshore Services B.V. signed a letter of intent with Jurong Shipyard Pte Ltd to build NSCV in Singapore; Jurong's parent Sembcorp Marine announced the contract, worth US$1 billion, had been awarded on July 15, 2015. A minimum freeboard prevents waves hitting the columns when sailing. The mess rooms, galley and food stores are located below the deckhouse on the tweendeck. The largest dual-fuel crane vessel in the world. HMC transports, installs and removes all types of offshore facilities. Heerema Marine Contractors (HMC) brings more than 50 years of specialized skills to the offshore oil, gas and wind industry and excels at transporting, installing and removing offshore facilities. The vessel is essentially a large platform supported by eight columns (four on each side), with one pontoon per side.

After its completion in 2019, SSCV Sleipnir succeeded Heerema's earlier SSCV Thialf as the largest crane vessel in the world. The excellent cooperation between Heerema and Sembcorp Marine ensured that the project was executed smoothly, on budget and according to the best possible safety and quality standards.”. Netherlands-based Heerema Offshore Services’ new-generation self-propelled, semi-submersible crane vessel, named Sleipnir, is being built by SembCorp Marine at its Tuas Boulevard Yard in Singapore. Named after the Norse God Odin’s eight-legged stallion, and newly completed at Sembcorp Marine’s Tuas Boulevard Yard, SSCV Sleipnir has a 220-metre by 102-metre reinforced deck area, making it the largest crane vessel to be built. The detailed design and construction phases followed in 2015 at Sembcorp Marine in Singapore. The Thialf was Heerema’s largest semi-submersible crane vessel in operation before the Sleipnir and the previous world record holder in its class. With extended cranes the vessel is more than 85 metres taller than the London Eye. We are proud to be part of this amazing teamwork.

The sterns are reinforced by skeg structures. Singapore, May 24, 2019 – 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.
