NYK Launches Japan’s First Fully Battery-Driven Work Vessel, e-Crea

Japanese shipping major Nippon Yusen Kaisha (NYK) has recently introduced the nation’s inaugural fully battery-powered work vessel, e-Crea.

The vessel, measuring 9 meters in length and 3 meters in width, was constructed by Keihin Dock, a subsidiary of the NYK Group, at its Koyasu Shipyard.

e-Crea, designed without an onboard diesel generator, will be utilized for supporting the docking and undocking of tugboats at the Koyasu Shipyard.

Environmental Sustainability and Innovation

As the global maritime industry shifts towards decarbonization, NYK Group has been actively exploring alternative fuels like ammonia while focusing on sustainable shipping solutions.

Keihin Dock, NYK’s shipbuilding arm, has played a key role in driving innovation and implementing new technologies, with fully electric work vessels emerging as a promising option.

Efficient and Eco-Friendly Operations

e-Crea operates solely on batteries charged from shore facilities at Keihin Dock’s Koyasu Shipyard, resulting in zero carbon dioxide emissions. The vessel also offers reduced operational noise compared to traditional fossil fuel-powered ships.

Its compact design enables agility in confined spaces, making it ideal for assisting with docking operations at shipyards. Japan Craft Inspection Organization (JCI) has classified the vessel.

Safety Measures and Future Prospects

To address potential fire risks from elevated temperatures in batteries and electric motors, the team implemented advanced cooling systems and enhanced safety measures within the vessel.

NYK’s commitment to electrification extends to larger vessels, with plans to incorporate electric propulsion systems in tugboats and work vessels to accelerate decarbonization efforts in maritime and port services.

Data and insights from e-Crea’s construction and operation will inform the development of an electric-propulsion tugboat slated for completion in December 2026.

Continued Innovation in Sustainable Shipping

In addition to e-Crea, NYK recently completed the world’s first commercial ammonia-fueled vessel, Sakigake, which demonstrated a significant reduction in greenhouse gas emissions.
