Electric tugs

Recent pictures of the two HYDROMASTER® Series 4 Transom mounted Azimuth propulsion units installed on a fully Electric Pusher tug approaching completion at Padmos Shipyard in Stellendam. The shipyard is building this pusher tug for KOTUG International for deployment on the Dutch waterways, designed by C-Job Naval Architects. Total propulsion power on this sustainable design is 600 kW:

The completed push tug will look like this:

looks like off-the-shelf induction AC motors. Could be very good, as in easy to replace…or bad (not weather proofed?) They seriously can’t make a better enclosure?

This concept is based battery power so I would assume that the motors are DC (no need for converters). Here is more on the concept:

The swappable battery banks is key to the operation:

PS> Since these tugs are for inland waterways I presume that “rain proof” is sufficient cover for the motors.

The L/B Factor: 1.0 (??)

In addition, the vessel’s powerplant will be outfitted with the option for 100% electric power supply.
