Steel Cutting Ceremony of AmpRA 3600 Tug for Tianjin Port

October 3, 2025

On September 9, 2025, a steel cutting ceremony was held by Zhenjiang Shipyard at their facility in Jiangsu Province, China to mark the construction of an electric battery-powered tugboat, designed by Robert Allan Ltd. for Tianjin Port Towing Company. This vessel is the towing company’s first to feature electric battery propulsion.

This will be the first AmpRA series tug developed by Robert Allan Ltd. for operation in China. The pure battery-electric tug is designed to be equipped with a battery system of 7,315 kWh, establishing a new benchmark for battery capacity among tugs under 500 gross tons.

As the third generation of smart ships in the fleet, the tug will carry smart ship notations: i-Ship(M) for advanced machinery systems, i-Ship(E) for energy efficiency, i-Ship(I) for integrated platform capabilities, and i-Ship(T) for towing operations.
