Mitsui O.S.K. Lines, Ltd. (MOL, President: Akimitsu Ashida) announced test results showing the benefits of a heat-shielding paint that can save fuel, reduce CO2 emissions, and reduce long-term vessel maintenance costs.

The Technology Research Center in MOL’s Technical Division just completed a yearlong test of heat-shielding paints from 10 manufacturers. Along with group company M.O. Engineering Co., Ltd., MOL applied a test coating of the highest-rated paint to the deck of a large ferry. The test confirmed that the paint effectively reduced temperatures inside the ferry and saved electricity by reducing the load on the vessel’s air conditioning system.

The heat-shielding paint used for the test helps block heat generated by sunlight. In addition to improving passenger and crew comfort, boosting air conditioning efficiency, and cutting CO2 emissions, the paint is durable and weatherproof, and will cut ship maintenance costs. The paint is already used on land for buildings, large bridges, factories, tanks, plants, warehouses, vehicles, and railroads. However, this test marks the first use on a large vessel.
