Development Propulsion

Load profiles in the merchant marine sector typically have engines running at maximum continuous rating for days and even weeks. A harbour tug is more like an excavator or forklift truck on land, travelling at reduced load from one workplace to another. Niigata Power Systems set out to realise the fuel, emissions and wear savings possible by applying a hybrid drive system in a tug.

Environmental impact of harbour vessels

Reducing the environmental impact of ships has become a very important issue in recent years with the enforcement of environmental regulations becoming stricter worldwide. Tugboats are small vessels which assist the departure and arrival of large ships in ports, and many are deployed around the world. Since seaports are often surrounded by populated areas, and many ships arrive and leave, attention has focussed on reducing the environmental impact of ship’s engines on surrounding areas.

Although the hull of the tugboat is small, a highly powered main engine is applied...
