Daito held a signing ceremony for a collaboration agreement with Kawasaki Heavy Industries (KHI) and Daizo Corporation to construct the electric vessel (EV) tugboat.
The EV tugboat will feature a high-capacity battery of 3.2MWh, operating on green electricity charged into the battery.
This approach significantly reduces fuel consumption and carbon dioxide emissions compared to conventional tugboats equipped with heavy fuel oil engines.
The innovative hull design and automatic control of onboard power demands optimise energy consumption.
