ABB Azipod Propulsion for Orange Marine Cable Ship
Integrated ABB power and propulsion package win from Colombo Dockyard brings milestone Azipod installation for advanced cable-laying and repair vessel that will support offshore wind farms. The high-tech vessel will be delivered by Sri Lanka’s leading shipbuilder in 2023, joining an Orange Marine France fleet which now accounts for 15 percent of the world’s specialized cable laying and repair ships. The 100-metre vessel will feature a full power, propulsion and automation package from ABB, including the landmark Azipod® system. Financial details of the contract were not disclosed.
The vessel, needed for both cable laying and repair, has been developed by Norway’s Vard Design, a Fincantieri Company, to meet specific priorities on power consumption and performance. Station-keeping accuracy and maneuverability are essential for what can be complex cable laying and repair operations, while the ship also needs relatively high speeds to achieve rapid or urgent deployment.
The twin 1.8 megawatt Azipod units selected to meet the shipowner’s requirements for high transit speeds with maximum fuel efficiency while providing the 360-degree maneuverability to ensure station-keeping performance even in challenging weather conditions. Also integral to the package is an ABB energy storage system enabling electrical power back-up using 500 kWh batteries, which will reduce fuel consumption during cable work and ensure continuity in the event of an unexpected shutdown.
The overall power setup will be controlled by ABB's Power and Energy Management System, which will also increase fault tolerance and provide a high degree of reliability while ensuring the maximum lifetime for the batteries.
