In December 2024, successful trials were conducted on a new system using industrial laser technology to remove rust, paint, and other coatings from ship hulls. Mitsui O.S.K. Lines (MOL), MOL Drybulk, and Tsuneishi Shipbuilding collaborated on the project, which aims to create a more environmentally friendly system with potential for automation. The test was performed on one of MOL Drybulk’s bulkers at the shipyard, with Furukawa Electric developing the rust and coating removal system.
Furukawa Electric, in partnership with MOL and MOL Drybulk, has been working on a rust and coating removal system for onboard maintenance since 2021. The system utilizes “InfraLaser” technology developed in industrial lasers, and demonstration experiments have also been conducted with Tsuneishi Shipbuilding since 2022. By optimizing irradiation conditions for rust and paint removal in ship undercoatings, the companies aim to improve efficiency and reduce environmental impact during ship repairs.
The current method of removing rust and coatings during ship repairs involves sandblasting, which scatters waste materials and paint debris, requiring recovery efforts and environmental precautions. By transitioning to a laser-blasting method, the companies anticipate minimal waste, dust, and noise generation. They plan to develop an innovative laser application system to replace conventional sandblasting methods and automate the ship maintenance and repair process, ultimately improving environmental sustainability and occupational health in shipyards.
