Daito Corporation, a subsidiary of K Line, is building a second electric tugboat for Tokyo Bay operations. The vessel will be a 260 gross ton class tug with a 4,400 PS motor and a new DC power distribution system. It is designed as a standard model for future electric tugboats and will use a condition monitoring system to optimize power supply and reduce fossil fuel use. Completion is scheduled for July 2028. The project is part of Japan's subsidized program for non-fossil energy in coastal shipping and supports the development of carbon neutral ports in Tokyo Bay. Daito's first electric tugboat is already under construction. The second vessel will have higher output and a shoreside charging system built by TOA CORPORATION. This is a concrete step toward decarbonizing port operations in one of the world's busiest shipping zones.

Daito building a second electric tug for Tokyo Bay. 260 gross tons, 4,400 PS motor, DC power distribution. First one was 199 tons. This one is meant to be a standard model for future electric tugs. Completion 2028.

Worth noting the auxiliary generator still runs when battery is low. So it is a hybrid in practice, not fully electric. The CMS that optimizes power supply based on operational data is the real story here. That is where the fuel savings come from.

The shoreside charging equipment is being built by TOA CORPORATION. That is a key detail. Without the charging infrastructure, the tug is just a very expensive boat. Glad they are bundling the shore side work into the project.

This is funded under Japan's subsidy program for non-fossil energy in coastal shipping, run by METI and MLIT. That is the kind of targeted industrial policy that actually moves the needle. Not a tax credit. A direct build subsidy for a specific vessel class.
