The Orion is a construction vessel for the coming generations of offshore wind turbines. It was built at COSCO in China for the Belgian group of companies Dredging, Environmental and Marine Engineering ( DEME ) and delivered in 2019.
description
The special feature of the new, 216.5-meter-long installation ship Orion , sailing under the Panama flag, is the heavy-duty ship crane with a nominal load of 3000 tons at a radius of 50 meters and a lifting height of around 170 meters above sea level. So can the ship is not only the most serious Jackets , Monopiles of future generations of components and offshore - wind turbines will be installed, but also the future decommissioning of offshore wind turbines are to be so. Modules and building structures of the HVDC platforms or the oil and gas production platforms to be dismantled can thus be lifted.
Ballast water can be pumped around inside the ship to keep it level when the crane is under load.
In November 2019 began at Liebherr MCCtec in Rostock the construction of the heavy-duty crane type HLC 295,000 of the company Liebherr . The 145 meter long boom was installed on the slewing ring at the beginning of April . On May 2, during a lifting test of a 5500 ton pontoon filled with water, the crane hook broke under a load of 2600 tons; the crane boom overturned and broke. The damage is estimated at a high double-digit million amount. Twelve people were injured, two of them seriously. At the time of the accident, 120 people were on board.
| Hub | Lifting capacity |
Max. off charge |
Max. Lifting height above deck |
|---|---|---|---|
| Main hub | 5000 tons | 35 meters | 135 meters |
| Auxiliary lift 1 | 1500 tons | 70 meters | 165 meters |
| Auxiliary lift 2 | 200 tons | 151 meters | 175 meters |
The total installed power of the ship is 44,180 kW. This means that the Orion can reach a speed of around 12 knots. It was equipped with DP 3 capability as no lifting legs were installed. The ship has dual-fuel engines and can run on diesel oil or natural gas ( LNG ). For economical consumption, exhaust gas boilers and heat exchangers were installed in order to use the thermal energy from the exhaust gases and the cooling water for power supply and heating or hot water supply.
The ship has facilities for a crew of around 131 people, which can be expanded by around 100 seats.
