NYK introduces Japan’s first battery-driven workboat

During its construction, Keihin Dock overcame technical challenges including its weight and vessel balance from the substantial battery modules. These were overcome by reconfiguring equipment placement and cabling to optimise internal space and ensure safe and stable navigation.

Keihin Dock installed multi-layered water-cooling systems and integrated air ducts to mitigate the fire risk from rising temperatures from batteries and electric motors.

“Enhancements to the battery room included fireproofing measures and protection against hazardous gases, along with improved ventilation,” said NYK. “These measures ensure the vessel upholds robust safety standards.”

NYK is using data and insights from e-Crea’s construction and operations on its next decarbonisation project – building an electric-propulsion tugboat, scheduled for completion in December 2026.

The Japanese shipping group intends to construct and operate more low-emissions vessels as part of its commitment to energy-saving innovations and next-generation solutions that reduce greenhouse gas emissions.
