Battery Electric Tug for Tianjin Port
July 23, 2025
Robert Allan Ltd. has been awarded a contract to design an AmpRA 3600 tug for Tianjin Port in Northern China. The AmpRA 3600 series tug will be constructed at Jiangsu Zhenjiang Shipyard (Group) Co. Ltd. This builds on a successful conventional propulsion design for the same Owner and shipyard, with two vessels of similar hull form in service, but with a much greener propulsion system!
The AmpRA 3600 will have all powering from batteries, with no generator sets onboard, making it a fully battery electric and diesel free ship handling tug. It will also be the first Robert Allan Ltd. battery electric vessel operating in China.
The main equipment will be supplied by leading Chinese manufacturers, including over 7 MWh of batteries from CATL, the electrical system from the 704 Institute, and L-drives from Nanjing High Accurate Marine Equipment Co., Ltd.
The AmpRA 3600 has the following key vessel particulars:
- Length overall: 35.8 m
- Breadth, moulded: 11.2 m
- Depth, least moulded: 5.2 m
- Bollard Pull: 62 tonnes
- Accommodations: 7 persons
Robert Allan Ltd. is proud to be involved in such an innovative design with our valued clients.
