Concept Design for World’s First Pure-Electric Tanker Revealed


Published Jan 30, 2019 5:23 PM by The Maritime Executive

Asahi Tanker Co. and Exeno-Yamamizu Corporation Tokyo have developed a new domestic shipping tanker design which incorporates zero emission electric propulsion using lithium ion batteries.

Commercial model development of the “e5” design is underway for bunker supply vessels trading in Tokyo Bay. The first vessel is expected to be launched in the fourth quarter of 2020. 

The project partners are also working on the development of “e5” coastal vessels with longer cruising range. 

ClassNK will provide technical advice on ship design and electric propulsion.

The use of electric propulsion controls emissions of CO2, Nox and SOx and also minimizes noise and vibration on the vessel. The design offers economic efficiency through the use of the internet of things and digital tools coupled with improved propulsion performance from using electricity. A simple hull construction and the use of automated equipment on board will reduce the work load for the crew.
