EBDG, Marine Miller Team Up for Electric Truckable Tug

Naval architecture firm Elliott Bay Design Group (EBDG) and Virgina-based marine metal fabrication shop Miller Marine joined forces to design and construct a fully electric truckable tug, based on the former’s announcement on Nov. 29.

The fully electric truckable tug is said to be designed as a multi-functional utility boat servicing marine construction, tending dredges, tending buoys, short range ferry operations and other nearshore operations such as crew transportation or line handling.

The vessel has an overall length of under 26 feet and is said to be powered by two permanent magnet motors with a total power of more than 300 kW.

An electrical propulsion system will be incorporated into the truckable tug design and once the design stage is finished, Miller Marine will construct the vessel at its 15,000 square foot production facility that uses modern CNC technology to facilitate efficient production of marine projects.

In addition to this, shore power will be used to recharge the boat’s battery banks overnight that will take no more than eight hours. The electric vessel will operate with contingency for more than 12 hours on a full charge. A closed-loop fluid cooling system will also provide temperature control of the batteries, motors and electronics, which will increase its lifespan.

Furthermore, the tug is “ideally suited” for shallow and silty water operations and is intended to “support public agency and private enterprise marine construction operations and short-range logistics.”
