Coating Design of Ice Belt Zone in Arctic Vessels

摘要

The demand for an ice class ship may rise due to the opening of arctic sea routes. Ice class ship should be designed to cope with the severe environmental conditions of arctic sea such as a high mechanical impact and abrasion damage, caused by pack ice, ice bergs and low temperatures. The ice class ship hulls are coated with anti abrasion and low friction coatings, such as a solvent free or high solid epoxy. These coatings require a plural component spray gun and a high grade surface preparation. In this study, the coating performance for the arctic vessels, such as puncture absorbed energy, abrasion wear loss, coefficient of friction and impact absorbed energy were evaluated. From these results, a proper coating design for the arctic vessels is proposed.
