For Damen Shipyards Group, Bakker Sliedrecht is delivering a silent electrical propulsion system for a state of the art fishery research vessel. The vessel is being built for the Angolan Ministry of Fisheries and will be used to help develop and preserve the important Angolan fishing industry.
In order for a research vessel to be successful, it has to operate extremely quietly. Therefore, this ship has to comply with the ICES 209, the international standard for silent sailing. To achieve this, two silent Indar propulsion motors in tandem configuration will be coupled directly to the thrusters. Furthermore, the brand new ABB ACS 880 water-cooled inverter modules will be used to create a frequency converter with a special filter to comply with all requirements.
