Vancouver, B.C.-based naval architecture firm Robert Allan Ltd. has been awarded a milestone contract to design a fully battery-electric tug for Tianjin Port in Northern China, marking a significant step toward cleaner port operations in one of the country’s busiest maritime hubs.
The new tug, an AmpRA 3600 series vessel, will be constructed at Jiangsu Zhenjiang Shipyard (Group) Co. Ltd. and represents the next evolution of a proven design. The shipyard and Robert Allan Ltd. previously collaborated on two conventionally powered tugs of similar hull form for the same client. This latest project retains the successful hull form but replaces traditional diesel propulsion with a fully electric system, creating a greener, diesel-free ship-handling tug.
