Jotun has successfully completed testing of coating systems consistent with the new IMO PSPC rules for cargo oil tanks (COT), scheduled to come into force in January 2013.
Focused on maintaining the long-term integrity of tanks, the new IMO rules require that all coatings used in the tanks must provide long-term protection against the corrosive effects of crude oil. Jotun has successfully completed testing for coating systems at one of the IMO-approved test institutes (COT in the Netherlands), passing with several tank-coating systems.
Two test methods were utilised. The first test simulates the composition of the vapour phase in crude oil tanks both in ballast and in fully loaded condition. The second test simulates immersion in a crude oil tank with a model liquid developed to replicate some of the most corrosive crude oils.
