Asahi Tanker unveils design of electric bunker tanker

Japan’s Asahi Tanker Co and Exeno-Yamamizu Corporation Tokyo have jointly developed an electric zero emissions bunker tanker set for commercial launch in the last quarter of 2020.

The model development of this 500-dwt electric bunker tanker of “e5” design is underway for all bunker tankers operating in Tokyo Bay, Japan’s main bunkering port.

The project is also working on creating “e5” coastal bunker tankers that can sail over longer distances.

ClassNK has been appointed to make give technical advice on the ship design and electric propulsion.

Asahi Tanker stated that the “e5” concept aims to offer solutions to issues such as shortage of crew, vessel demand balance and environmental regulation, so as to contribute to the overall sustainability of the domestic shipping sector.


The pure electric bunker tanker is expected to reduce emissions such as CO2, NOx and SOx, along with minimising noise and vibration.

The operation will also be efficient through the installation of digitalised systems and tools, coupled with automated equipment to reduce manual work for the crew.
