Nippon Yusen Kabushiki Kaisha (NYK) has signed a memorandum of understanding (MoU) with Japan’s Toyokoh to explore the potential of a joint business development for an existing technology that could reduce steel corrosion on-board ships.
Toyokoh has developed CoolLaser, which uses laser technology to remove rust from steel structures.
Under the MoU, both the companies will develop a device, system, and measures for the maritime industry by investigating the impact of lasers on steel material and coating adhesion.
The companies will also study the safety and improvements that can be incorporated to CoolLaser.
They are planning to try the technology on an actual ship while the vessel is in dry dock.
It is said that CoolLaser can remove rust quickly even in narrow spaces. It can be used to eliminate any salinity, as well as reduce dust and waste.
Using CoolLaser, NYK seeks to reduce the maintenance works of the crew on deck, and reduce dry-dock costs for repairs.
The technology is also expected to help NYK with a more efficient and environment-friendly maintenance method.
“The technology is expected to help NYK with a more efficient and environment-friendly maintenance method.”
NYK in a statement said: “Steel used on a ship’s deck is always susceptible to rust due to the harsh outdoor ocean environment that can lead to corrosion arising from severe salinity, temperatures, humidity, and ultraviolet rays, all exacerbated by scratches resulting from wear from cargo loading etc.
“During voyages, crew members usually remove rust using power tools and then repaint, but a tremendous amount of repetitive work is required, and the repair does not remain in good condition for long.”
The process of sandblasting is generally used to remove rust on the shell plates during dry dock.
However, Sandblasting releases large amounts of dust and waste when an abrasive material such as sand is targeted at a high-speed onto the shell plates to eliminate surface contaminants.
