ABB will power Japan’s first electric tug for efficient and sustainable operations

  • ABB under contract with IHI Power Systems Co.,Ltd. is developing an electric tug for Tokyo Bay ports for Japanese towing specialist Tokyo Kisen Co. Ltd
  • The new tug will be equipped with ABB’s award-winning Onboard DC Grid™ power system platform, which enables simple, flexible and functional integration of power sources and loads
  • The first vessel of this type to operate in Japan, the Taiga supports net greenhouse gas (GHG) emissions targets without compromising performance

The electric tug Taiga is the result of a collaboration between Tokyo Kisen Co., Ltd. and e5 Lab Inc., a Japanese consortium with the goal of planning and developing all-electric ships.

Built at Kanagawa Dockyard Co., Ltd. in Kobe, the tug is due for delivery at the end of December 2022, becoming the first vessel of its type to operate in Japanese waters. It is equipped with ABB’s Onboard DC Grid™ with high battery capacity. Designed to enable zero-emissions operations in port environments, the tug offers superior performance while supporting Japan’s ambition to achieve net GHG emissions from international shipping by 2050.

The Tokyo Kisen harbor tug will be used to maneuver other vessels by pushing or towing them with 2.5 megawatt-hour battery systems supplied and integrated by ABB, reducing greenhouse gas emissions on a daily basis and acting as a spinning reserve. increase the power to avoid prolonged outages. The tug’s scalable configuration also allows it to achieve emissions-free operations by integrating alternative power sources as technologies mature.

“ABB is honored to be involved in such an important project to power Japan’s first electric tug,” said Munekazu Tanikawa, Local Division Manager, ABB Marine & Ports. “Our hybrid and electric solutions have established a solid reputation in the short sea shipping segment, now enhanced by this prestigious opportunity in a highly competitive market.”

In addition to the energy storage solution, ABB provides the tug with its award-winning Onboard DC Grid™ power system platform, which enables simple, flexible and functional integration of energy sources and loads. Leveraging Onboard DC Grid™, the tug motors will be able to run at variable speeds for optimized energy savings at each load level. This helps reduce fuel consumption, thereby reducing environmental impact. The batteries will be able to power the tug’s propulsion system almost instantaneously, where ABB’s Power and Energy Management System (PEMS™) will control the overall power distribution, increase tolerance failures and will provide a high degree of reliability.
