16 October 2017

Bakker Sliedrecht has been awarded a contract for the engineering, delivery, and commissioning of the main electrical power package of the offshore installation vessel Orion. 

The DP3 vessel will feature an unrivalled combination of exceptionally high transport and load capacity, impressive lifting heights and green technology. The vessel will be built at COSCO Qidong in China. Orion’ will be deployed by DEME’s subsidiary GeoSea for the construction of the largest offshore wind farms and deliver offshore construction services.

Empowering the first next generation offshore installation vessel

With a total installed electrical power of 44,180 kW, ‘Orion’ will be equipped with a high-tech crane with lifting capacity of 3,000 tonnes at more than 50 meters. The loads can be lifted to an unrivalled height of more than 170 m. Deck space has been maximized to provide exceptionally high transport and load capacity. The vessel can take the heaviest monopiles, jackets, wind turbine components and structures in a single shipment. With this unmatched combination of high load and lifting capacity, ‘Orion’ can transport and install the next generation of giant multi-megawatt wind turbines.

Highlights of our scope of work are:

  • ​4 x Indar generators
  • 4 x Indar main propulsion electrical motors
  • 2 x Retractable thruster motors
  • 2 x Tunnel thrusters
  • 2 x 11 kV switchboard
  • 2 x 690 V switchboards
  • 4 x 440 V switchboards for DP essentials
  • 2 x LV electrical drive systems for eight point mooring system
  • 4 x LV electrical drive systems for azimuth thrusters
  • 2 x LV electrical drive systems for bow thrusters
  • 2 x LV electrical drive systems for retractable thruster
  • Integrated automation system
  • Electrical system integration incl. construction supervision
  • Commissioning and sea trials

Powerful ABB ACS 880 low voltage multi-drive systems

The Orion will be equipped with the brand-new ABB ACS 880 liquid-cooled low voltage multidrive system. The new model of ABB has a very high power density, yielding a lot of power out of a small footprint. The ABB ACS 880 is maintenance friendly and already compliant with future regulations.

Experienced with building DP offshore installation vessels

Jan Gabriël and Wouter Eyckmans, heads of DEME’s newbuilding and automation departments: “We look forward to working with Bakker Sliedrecht on a ship that is breaking boundaries. Our experience with Bakker Sliedrecht, gained during earlier projects, and the experience of Bakker Sliedrecht with delivering complex electrical systems for DP offshore installation vessels strengthens our confidence in a great project execution.”

Delivery in 2019

The Orion will be delivered to GeoSea in 2019.
