British Polar Engines

Extended inspection, test bed and storage facilities contribute to increased output of finished engines.

In 1911, the first motor vessel to cross the Atlantic, the Swan Hunter-built ore-carrier Toiler, was powered by a Polar engine.

[3] At about the same time Roald Amundsen in the Fram was conquering the South Pole, and it is from that successful expedition that the engine derives its name.

British Polar engines were of the two-cycle type, built under licence from Nydqvist & Holm, Trollhättan, Sweden.

This early design has been developed and extended to a wide range of engine sizes covering powers from 300 to 4,000 bhp (220 to 2,980 kW) without supercharging.

The British Polar Engines Diesel Motors of the Oberon -class submarine HMS Ocelot . The engines charged the batteries for the silent electric propulsion of the ship. HMS Ocelot is now a museum ship in Chatham Dockyard.
