Japan’s NYK introduced the “e-Crea”, the first fully battery-powered workboat in Japan. The vessel was built by Keihin Dock, its specialized shipbuilding subsidiary, at the Koyasu shipyard in Yokohama.
e-Crea: a work vessel with clean technology and functional design
Designed for port maneuvers in support of tugboats, the e-Crea is powered exclusively by electric energy. electric powerwithout any type of diesel generator. Power comes from batteries recharged on shore, which completely eliminates carbon emissions during operation. This feature also significantly reduces operational noise, making it a safer and more comfortable option for dense port environments.
Its compact 9-meter hull facilitates navigation in tight spaces, while its electrical system allows continuous operations with high energy efficiency. The vessel has a capacity for 14 persons and complies with Japan Craft Inspection Organization (JCI) standards.
During the integration of the electric propulsion system, they faced challenges such as the increased weight of the battery modules and the need to maintain the ship’s stability. To this end, the internal layout and wiring were redesigned, optimizing space and ensuring safety.
Water cooling and advanced ventilation systems were also implemented to control the temperature of batteries and motors, including fire and gas protection measures. These improvements were key to meeting stringent safety regulations.
Towards an emission-free port fleet
The e-Crea is part of NYK’s strategy to expand electrification in its port operations. The experience gained with this vessel will be applied to the development of an all-electric tugboat, scheduled for delivery in 2026. This approach reinforces NYK’s role in innovating sustainable marine solutions and progressively adopting carbon-free technologies.
With this breakthrough, Japan joins global trends that seek to transform the maritime sector through clean energy, battery technology and smart design for low environmental impact operations.
