Mitsui O.S.K. Lines (MOL), MOL Drybulk, Furukawa Electric, and Tsuneishi Shipbuilding have successfully conducted a field trial of the "InfraLaser" system on a vessel's outer hull. The trial, held in December 2024, tested the laser-based rust and coating removal technology as an alternative to traditional sandblasting methods.
Furukawa Electric has been developing the system since 2021 with support from MOL and MOL Drybulk. It uses industrial laser technology to reduce waste, dust, and noise from the coating removal process. Since 2022, Furukawa Electric and Tsuneishi Shipbuilding have been working on applying the system to ship repairs.
Currently, ship maintenance requires removing rust and old coatings for inspections and repainting, typically using sandblasting, a method which generates a large amount of debris, necessitating lengthy cleanup. The laser-based alternative aims to minimise environmental impact and improve workplace safety.
During the trial, Tsuneishi Shipbuilding provided technical feedback, while MOL and MOL Drybulk contributed insights as ship operators. The results confirmed the system's effectiveness on an MOL-operated vessel.
The four companies plan to develop the technology further, refine its design for practical use, and explore automation to improve efficiency. The initiative is part of broader efforts to modernise ship maintenance while reducing environmental and labour impacts.
