Joint press release
17 January 2019

Concept Design and Engineering for World’s first Pure-Electric tanker
completed
Asahi Tanker Co. Ltd, together with its partner Exeno-Yamamizu Corporation Tokyo,
has jointly developed the new domestic shipping tanker design which incorporates“zero emission electric propulsion”.
In anticipation of future adaptations to regulatory conformity ClassNK has been
appointed to make technical advice on ship design and electric propulsion.
Commercial model development of “e５” design is underway for all bunker supply
vessels trading in Tokyo Bay. The target of the first vessel launching is set for quarter
four 2020. The project is also working for creating “e５” coastal vessels which would
require longer cruising range.
The “e５” concept creates solutions to issues such as shortage of crews, vessel demandbalance and environmental regulation thus contributing to the sustainability of thedomestic shipping industry. The project is confident that by utilizing the “e５” conceptof ocean transport that a stable energy supply will be achieved enriching people’s lives
and adding value to each client.

The new vessel design and related project infrastructure development will be known
as “e５” which captures the five core elements of;
1. Electrification
The ships core energy source will be electricity, achieved by way of adopting
lithium-ion batteries.
2. Environment
Emission controls such as CO2, NOx, SOx together with minimizing noise and vibration
along with improvements in vessel operation environmental controls at sea and inport.
3. Economics
Achieving economic efficiency through installment of IoT and digital tools coupled withimproved propulsion performance from using electricity.
4. Efficiency
Simple hull construction and installment of automated equipment can reduce work
load for the crew.
5. Evolution
Digitalization and technological advancement leading to the most advanced designconcept for the future of domestic shipping.
