Introduction Vessel operators who trade in ice face a number of difficult challenges: • Extremes of low temperature • Severe abrasion • Ice adhesion to the outside shell Traditional anticorrosive systems, including standard pure epoxies, are unable to offer a solution to these challenges. Intershield 163 Inerta 160, an abrasion resistant ice coating developed over 30 years ago, has established an unrivalled in service performance reputation. Specifically designed for operators that trade in the Baltic Sea region, Intershield 163 Inerta 160 has been specified and used successfully on over...

Because of the severe ice abrasion experienced, class societies stipulate that vessels trading in ice should have increased steel plate thickness, generally referrred to as the 'incremnent due to abrasion Some class societies however, such as Lloyds Register, DNV and the Russian Maritime Register of Shipping, recognise the benefit of applying a specialist, low friction, ice resistant coating on the hull. Not only do such coatings aid the passage of the vessel by virtue of low frictional resistance but they also protect the steel from corrosion by providing a physical barrier to the...

“We have used Intershield 163 Optimum Protection To get the optimum level of protection from a specialist, abrasion resistant coating, it is advisable to coat the complete underwater hull up to 0.5m above the Load Water Line (LWL). Because of the way ice breaks under pressure, ice breakers in particular benefit from complete coating of the underwater hull. Inerta 160 for many years on our ice strengthened vessels and we have noticed that this paint, which is more Generally, all parts of the hull could be in contact with ice whether it is during the initial ice break, or the subsequent...
