Electric tanker design unveiled

Feb 01 2019


Asahi Tanker, in co-operation with Exeno-Yamamizu Corp Tokyo, has developed a domestic tanker design, which incorporates ‘zero emission electric propulsion’.

In anticipation of future regulations, ClassNK was appointed to advise technically on the design and electric propulsion.

The development of a commercial model, dubbed ‘e5’, is underway to operate as a bunker vessel operating in Tokyo Bay. The target launch for the first vessel is the fourth quarter of 2020.

Work is also ongoing to develop ‘e5’ coastal vessel, which would require longer a cruising range.

The ‘e5’ concept will alleviate the problems of crew shortage, vessel demand balance and environmental regulation.

’e5’ stands for five core elements;

1) Electrification - The ships core energy source will be electricity, achieved using lithium-ion batteries.

2) Environment - Emission controls, such as CO2, NOx, SOx, together with minimising noise and vibration along with vessel operational improvements, will be seen at sea and in port.

3) Economics - Achieving economic efficiency through the installation of IoT and digital tools, coupled with improved propulsion performance from using electricity.

4) Efficiency - Simple hull construction and the fitting of automated equipment can reduce the crew’s work load.

5) Evolution - Digitalisation and technological innovations leading to the most advanced design concept for the future of domestic shipping.

The 499 gt, 1,300 cu m capacity design is powered by two 350 kW azimuth thrusters and one 130 kW bow thruster, while the concept designer was Groot Ship Design.
