Alstom Alspa Drive Fitted on Reasearch Vessel

Alstom installed its latest generation ALSPA drives in a new research vessel, which is being built by Alstom Leroux Naval, in Lorient, France. The deep sea research vessel, Pourquoi Pas, owned by Ifremer, will be the first ship to be fitted with the new ALSPA MV7000 converters as part of a contract for an electric propulsion system. The 344-ft. (105-m) vessel, which will operate at a service speed of 13.3 knots, is due to be delivered to Ifremer in Spring 2005. It will be used for both civil deep-sea oceanographic- going expeditions and hydrography missions.

The Pourquoi Pas will feature two shaftlines, driven by two 1,650 kW at 148 rpm induction motors, supplied by three-level medium voltage PWM Press-Pack IGBT ALSPA MV7000 converters.

The ALSPA MV7000 has been specifically designed for marine applications.

It is particularly suitable for induction motors up to 30MW at 6.6kV and offers a substantial reduction in underwater motor noise - particularly beneficial for research activities - which avoids the need for filters.
