Bakker Sliedrecht has been contracted for the engineering, delivery, and commissioning of the main electrical power package of 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. The Orion will be deployed by DEME’s subsidiary GeoSea for the construction of the largest offshore wind farms and deliver offshore construction services.
The Orion will have a total installed electrical power of 44,180 kW and be equipped with a high-tech crane with lifting capacity of 3000 tonnes at more than 50 m. The loads can be lifted to more than 170 m. Deck space has been maximised to provide high transport and load capacity. The vessel can take the heaviest monopiles, jackets, wind turbine components and structures in a single shipment and will be able to install the next generation of giant multi-megawatt wind turbines.
The highlights of Bakker Sliedrecht's 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 including construction supervision
- Commissioning and sea trials
Powerful Low Voltage Multidrive System
The Orion will be equipped with the new ABB ACS 880 liquid-cooled low voltage multidrive system. ABB's new model has a very high power density, yielding a lot of power out of a small footprint. The system is maintenance friendly and already compliant with future regulations.
The Orion will be delivered to GeoSea in 2019.
