Asahi Tanker Co. Ltd and the Exeno-Yamamizu Corporation say they have jointly developed a new tanker design that incorporates “zero emission electric propulsion”.
Their ‘e5’ design has been developed for the construction of all new bunker supply vessels operating in Tokyo Bay, with the first launch scheduled for the end of 2020.
ClassNK has been appointed to oversee the technical aspects of the electric propulsion and naval architecture.
Larger coastal versions with longer ranges are also being planned.
According to the companies, the e5 concept will create solutions to issues such as crew shortages and new environmental regulations.
The ship’s core energy source will be electricity – achieved by adopting lithiumion batteries.
It is claimed that the design will achieve economic efficiency through IoT and digital tools coupled with improved propulsion performance from using electricity.

Length overall: 60m
Propulsion: 2 x 350 kW azimuth thruster, 1 x 130 kW bow thruster
Gross tonnage: 499 tons
Cargo tank capacity: 1,300 cubic meters
