ABB, the leading power and automation technology group, will supply the power, propulsion and energy storage solution for two of the most innovative vessels operating in the offshore oil and gas sector. The specialised vessels require an advanced propulsion and power generation system to perform its operation. The new Azipod D will help the vessels safely achieve millimetre precision at open sea.
The Azipod D is the latest generation of ABB’s award winning podded electric propulsion system. The vessels will each feature two 4.2 MW units. A hybrid cooling system using combination of direct seawater cooling and internal air cooling increases electric motor performance by up to 45%. Overall, the Azipod units will have a substantial impact on the ships fuel efficiency. Maneuverability and station keeping is the key for the vessels and the Azipod propulsor’s 360o steerable propeller makes it ideal for their requirements.
The Onboard DC Grid will cut fuel consumption by up to 27%. It allows the ships’ four 3600 kW generators, also supplied by ABB, to operate at variable and optimum speed. The vessel is also equipped with batteries, which will further optimise use of the power plant and reduce energy consumption.
“The solutions we are providing will make these ships incredibly flexible and efficient to operate,” says Juha Koskela, Managing Director of BU Marine and Ports. “The Azipod D, Onboard DC Grid and energy storage are cutting edge technologies which match the demanding conditions often experienced in the offshore sector.”
In line with the high technology equipment onboard, the ships will also be equipped with ABB’s Remote Diagnostic Service. This system will connect the vessels to ABB’s shore side technical support centers where the technicians can monitor the performance of the vessel and ensure necessary support.The vessels will measure 90 m x 20 m and is designed to accommodate 36 persons onboard. They are designed by the Arendal, Norway based firm Cefront Technology, and will be built by COSCO. The vessels are designed to operate globally.
