When Ulstein Verft, a leading shipbuilding company headquartered in Ulsteinvik in Norway, required specialist marine alternators for a consignment of new offshore wind Construction Service Operation Vessels (CSOVs) it was building, it looked to STAMFORD | AvK to deliver what was needed.

The 30th SMM took place in Hamburg 6 to 9 September, for the first time in 4 years. With over 2,000 exhibiting companies and 30,000 industry visitors from more than 100 countries, the exhibition is key in the Marine market.

Dunkirk Little Ship Restoration Project Ltd, based in Hartlepool, approached Generator Solutions for a compact alternator for their small vessel as part of its restoration.

The ship, which is now 86 years old, was built in Great Yarmouth, UK in 1935, known as the M.V. Coronia and was taken over by the Admiralty for war duties and renamed H.M.S. Watchful on September 16, 1939.

H.M.S. Watchful sailed to Dunkirk and returned three times, saving 900 lives in the mass evacuation process.

Application overview

In marine applications, Shaft Electrical Machines (SEM’s) are connected to the vessels propulsion engine and are often required to operate in a multi-function role. They operate as an alternator providing the vessels primary electrical power supply, or as an electric motor providing a short term power boost alongside the propulsion engine, or as an independent method of propulsion, when the engine is out of commission. This article sets out to give an overview of the different modes of operation and the various methods of control.
