Intershield ® 163 Inerta 160 Abrasion Resistant Low Friction Ice Coating for LNGc The Ice-class Market The Arctic region is the latest new frontier for the oil and gas industry. Estimated that 22% of the world’s available oil and gas is within the Arctic Circle; the region could hold as much as 90 billion barrels of oil and more than 1,500 trillion cubic feet of natural gas. The new export-oriented port and pipeline initiatives (that will incorporate ice-class tankers) are focused in three areas Baltic Northern Russia Sakhalin Island

Intershield ® 163 Inerta 160 Abrasion Resistant Low Friction Ice Coating for LNGc Ice Abrasion Vessels trading in ice are exposed to extreme ice abrasion Class societies stipulate vessels trading in ice should have increased steel plate thickness – ‘increment due to abrasion and corrosion due to ice trading’ Some class societies such as Lloyd’s Register, Det Norske Veritas and the Russian Maritime Register of Shipping recognise the benefit of applying specialist, abrasion resistant, low friction, ice coatings Protection from corrosion even in high abrasion conditions For vessels trading in first year ice, the application of a recognised abrasion resistant ice coating can actually provide high levels of corrosion protection and result in an approved reduction in total steel plate thickness

Marine Coatings All products supplied and technical advice or recommendations given are subject to our standard Conditions of Sale. Intershield ® 163 Inerta 160 Abrasion Resistant Low Friction Ice Coating for LNGc Why a reduction in total steel plate thickness? The reduction in steel thickness allowed has NOTHING to do with Intershield ® 163 Inerta 160 being so strong that it helps strengthen the hull!!! It is ALL to do with minimising the corrosion that occurs if a coating is removed from steel, exposing the steel to the marine environment. Intershield ® 163 Inerta 160 helps the owner/operator to reduce steel plate thickness since the coating is ice-resistant and so stays on the steel protecting it from corrosion.
