Engineers to Meet to Discuss Electric Installations on Ships
The Institute of Electrical and Electronic Engineers (IEEE) is updating the IEEE 45 standard for electrical installations on ships. This is a big undertaking because so much has changed with new power systems on ships, from the cruise industry to integrated electric propulsion systems on warships. “With new voltages, power distribution systems and casualty power arrangements, the standard really needs a refresh,” says Moni Islam, an electrical engineer who is chairing the IEEE committee reviewing and revising the standard. Islam is asking qualified electrical engineers, to include maritime experience if possible, to contact him. He is inviting any and all interested parties…
Optimal Electric Ship Propulsion Solution
Throughout the history of shipbuilding, the key challenge too often has been how to build the right ship around a given propulsion system, rather than creating tailored propulsion system for the ship. That was true when the best propulsion "engines" available were sails, and it is also true for today's diesel, gas turbine and electric hybrid systems as well. The ideal, of course, is to allocate cargo space, cabin space, the shape of propulsion units, and even the shape of the ship's itineraries around the needs of the marketplace rather than around the limitations imposed by the ship's propulsion system. Factors that remain in the path of that ideal include the underlying efficiency across a broad operational range with which chemical energy is turned into mechanical energy…
Alstom Presents Integrated Electric Propoulsion at Euronaval
ALSTOM will present its latest developments in the field of electric propulsion at this year's Euronaval Naval Defence and Maritime Exhibition and Conference. In particular, its Mermaid™ electric propulsion system to be fitted on the future Landing Helicopter Docks (LHDs) for the French Navy. Mistral & Tonnerre will be the first military vessels ever to be propelled by this type of propulsion that has already been tried and tested in several merchant vessels. The manoeuvrablity and availability of the LHDs will therefore be improved considerably. ALSTOM will also present the Advanced Induction Motor (AIM), which was selected by the Royal Navy for its three new T45 destroyers currently under construction.
