Engineering firm Bakker Sliedrecht is to supply power packages for the world’s first LNG-fuelled offshore installation vessel, Orion.
The multipurpose vessel will feature a Class 3 Dynamic Positioning (DP3) system and will be deployed by GeoSea, a subsidiary of dredging specialist DEME, for the installation of offshore windfarms, marine construction projects, oil and gas industry services and decommissioning of offshore installations.
“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,” Wouter Eyckmans, head of DEME’s newbuilding and automation department, said.
Delivery scheduled for 2019
The Orion will be equipped with total installed electrical power of 44,180 kilowatts to drive a heavy-lift crane with lifting capacity of 3,000 tonnes at more than 50 metres. It is scheduled for delivery
“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,” a spokesperson for Bakker Sliedrecht said.
Finnish manufacturer Wärtsilä is to supply the dual-fuel LNG engines that will power the Orion. These include four 9-cylinder Wärtsilä 46DF dual-fuel electric propulsion engines, and two 6-cylinder Wärtsilä 20DF dual-fuel engines.
CSD order builds LNG portfolio
Earlier this year, Bakker Sliedrecht was awarded a separate contract to supply similar electrical power systems for the world’s first LNG-fuelled cutter suction dredger (CSD) vessel. The Spartacus is under construction by shipbuilder Royal IHC and will also be delivered to DEME in 2019.
The Spartacus will likewise feature a 44,180 kilowatt power system for which Bakker Sliedrecht will provide all engineering, delivery, and commissioning services. The vessel was designed in close cooperation with DEME, Vuyk Engineering Rotterdam, an IHC unit and IHC.
