DEME’s new offshore installation vessel Orion joins the fleet
DEME's revolutionary offshore installation vessel Orion officially joins its fleet. This next-generation vessel brings a game-changing installation concept to the offshore energy market, according to the company's release.
Orion is equipped with a powerful, 5,000-tonne crane and is designed to handle the enormous turbines and foundations of the future. With a total installed power of 44,180 kW and at 216.5 m long, the vessel has a large unobstructed deck and a deadweight that has been maximised so it can handle the heaviest components.
To enable the new installation vessel to handle the future generations of giant turbines and foundations, ‘Orion’ is also equipped with an integrated Motion Compensated Pile Gripper (MCPG), which has been designed by DEME’s and Huisman’s expert engineers.
Coupled with the vessel’s DP3 capability, the MCPG allows the monopiles to remain vertical and stable during installation in the seabed, despite waves and motions of the vessel, and crucially, to be installed without the use of mooring anchors.
Combining these engineering technologies and ability to transport the new giant turbines, jackets and components in a single shipment, Orion will speed up installation times dramatically, making the vessel an extremely cost-effective solution for wind farm developers.
Orion has dual fuel engines enabling it to run on LNG or alternative clean fuels, a Green Passport and Clean Design notation. Another environmental innovation is a waste heat recovery system that converts heat from the exhaust gases to electrical energy. The evaporation of LNG also cools the accommodation with a cold recovery system.
Orion will shortly set sail for its first project in Germany, where XL foundations will be installed at the Arcadis Ost 1 offshore wind farm. This will be followed by a decommissioning project in the UK. ‘Orion’ will also be deployed for the installation of 176 foundations at the Coastal Virginia Offshore Wind Farm in the US, one of the largest offshore wind developments in the world.
DEME is a world leader in the highly specialised fields of dredging, solutions for the offshore energy market, environmental and infra marine works. The company can build on more than 140 years of know-how and experience is a front runner in innovation and new technologies.
