Hybrid Rotortug

Published in category: Innovation

On 18 May, the Damen-built ART 80-32 Hybrid Rotortug RT Evolution was named at the Greenwich Ship Tier in London. Kotug operate the vessel in the Port of Rotterdam, for ship handling and escorting operations. Her hybrid propulsion is perfectly suited to the port’s large area of operations. RT-1078_1300_770

The RT Evolution was developed by Kotug in cooperation with Damen, Robert Allan Naval Architects and Rotortug. The vessel was built at Damen Shipyards Galati, in Poland. Damen is very confident in the design of the new hybrid tug and is building more on stock.

RT Evolution is fitted with three Caterpillar 3512C-HD main engines and Teco-Westinghouse 500 kW electric motors and can be operated electrically 80% of the time. As a result of the hybrid propulsion configuration, the vessel offers considerable savings in fuel efficiency of between 25-30%.

The RT Evolution has a bollard pull of 85 tonnes and a dynamic pull of 110 tonnes, giving her all the power of a large tug, but with all the manoeuvrability of a smaller vessel. Additionally, she is built for comfort, with an ergonomically arranged bridge, galley, cabins and mess room as well as extremely low noise and vibration levels.
