In any marine application, the need for highly dependable electrical generation is critical. Seagoing vessels generate electricity by using geared generators driven by gas turbines, internal combusting engines or steam turbines. These power generation units are heavy and take up considerable space.

By contrast, a DDS alternator is directly coupled to the turbine which eliminates the need for a gearbox, takes up less space, is quieter and is more dependable than conventional power generation methods. Perhaps the most important need aboard a ship that a DDS alternator fulfills is that it is significantly lighter in weight and smaller in size than a conventional generator. A traditional 8MW alternator and gearbox unit weighs around 50,000 lbs. A similarly rated DDS alternator weighs only 10,000 lbs.

Attracted by the weight savings, efficiencies and the durability of the DDS permanent magnet product, the United States Navy and Royal Navy have expressed considerable interest in using DDS power generation products in a planned fleet of all-electric ships, as well as for retrofit work in the current fleet. Whether for Naval or Merchant Marine seagoing vessels, DDS has the right solution for you.
