Posted on August 23, 2004

MAN B&W Diesel A/S, Holeby, Denmark, has announced the recent test and supply of a package consisting of two 8L21/31 and two 6L21/31 gensets. The gensets, which comply with the Gemran Blue Angel standard, will power an advanced diesel-electric research vessel for the State Ministry of Education & Science of Mecklenburg-Vorpommern, Germany. The vessel, Maria S Merian, is now under construction at the Lürssen-Krögerwerft, Rendsburg, Germany, and is scheduled for delivery towards the end of this year.

The vessel will have a length of 94.8 m, a breadth of 19.2 m and a draft of 6.5 m. A total main engine output of 5600 kW provides for the vessel’s hotel load and a maximum speed of 18 knots – and a service/cruising speed of 15 knots. The diesel-electric power for the vessel is supplied by the four L21/31 gensets. The gensets are integrated in a propulsion system, driving thrusters and a pump jet. STN ATLAS, Hamburg is supplying the electrical equipment for the drive system for two podded 1900 kW propulsors, as well as the electrical drive system for a 1600 kW pump jet in addition to transformers, generators, cable network, switchboards, and a complete power supply assembly for both the vessel and its scientific operations.
