The Sleipnir is a semi-submersible floating crane . With a length of 220 meters and a width of 104 meters, it is the world's largest semi-submersible crane ship, displacing the Thialf to second place. It is named after the eight-legged stallion Sleipnir of the Germanic god Odin .

Procurement and use

The Sleipnir, until December 18, 2015 NSCV ( New Semi-Submersible Crane Vessel ) Sleipnir (development name: GVA 20000 HLV), is a semi-submersible floating crane planned in 2013 and currently in operation with a lifting capacity of 20,000 tons using both Cranes. In 2013 GVA was commissioned to carry out a design study. The main design and feasibility study took seven months to complete. The Letter of Intent was signed on March 30, 2015 by William Gu, General Manager Offshore of Jurong Shipyard, and Jan-Pieter Klaver, CEO of Heerema Marine Contractors. Construction began on July 15, 2015 with an order value of 1 billion US dollars (around 896 million euros). After the Sleipnir was completed at the shipyard in Singapore , it was christened Sleipnir .

The Sleipnir is the world's first work ship to run on LNG ; In addition, low-sulfur marine diesel oil can also be used. After the test drives and crane load tests, she went on her maiden voyage to southern Spain, where she was being prepared for her first installation project in the Mediterranean.

Structure and drive

construction

The Sleipnir is designed as a semi-submersible and can therefore increase its draft during work by flooding ballast tanks. The hull consists of two floats, which are each connected to the deck structure by four columns; these also contain the 1,000 m³ LNG tanks.

Crane systems

The two tubular slewing cranes, each with a lifting capacity of 10,000 tonnes, and a 100 t base-mounted crane were designed and built by Huismann Equipment in China.

drive

The drive consists of 12 MAN 8L51 / 60DF generators. Each of these generators has a continuous power output of 7.8 MW (10,500 hp) at an average speed of 500 rpm (revolutions per minute) and an output of 8 MW (11,000 hp) at a maximum speed of 514 rpm. The generators have the dimensions of 10.1 m × 3.2 m × 5.3 m and a weight of 135 tons each. All generators drive 8 propeller pods with the type designation WST-65RU and an output of 5.5 MW each; 4 of the 8 gondolas are retractable. Together with the feed mechanism, these are 6 m wide × 5.5 m deep × 20 m high (including electric motor) and weigh 133 t; they are at the stern of the ship.

Dynamic positioning and anchor system

With the help of the dynamic positioning of class III, the ship should be able to hold its position even in the most adverse conditions at sea. The system was supplied by the Norwegian company Kongsberg .

The anchor system was supplied by Rolls-Royce . The system consists of three 12 t heavy anchors of the type "Stevpris Mk-6" in each corner of the ship. The anchors hang on 1750 m long steel cables.

Hot water supply

In order to ensure the warm water supply of the Sleipnir, two warm water boilers were built by Headmaster and installed on the ship. These have the dimensions of 2.5 meters in height and 7.5 meters in length; the diameter is 2 meters. The weight of the two hot water boilers is 12,500 kg each.
