IMO Wave Tank Test and COT Test (Crude Oil Test)

IMO, International Maritime Organisation, is the supervising organisation in the field of global shipping. For paint/coating systems and for ballast tanks there is the specification IMO Resolution MSC.215 (82), the so-called Wave Tank Test and for crude oil tanks there is the specification IMO Resolution MSC.288 (87).

For both tests COT has been certified by Lloyds and DNV/GL.

For the Wave Tank Test the COT laboratory has the required measurement setup, a large tank filled with synthetic seawater which, as a swing, goes back and forth in such a way that it simulates a sailing ship for a period of six months with all the temperature fluctuations that one might expect. Also a zinc anode is attached to one of the test panels.

The IMO COT Test (Crude Oil Test) includes an immersion and a gas test for protective coatings for cargo oil tanks of crude oil tankers. In a specific test liquid mixture and a specific humid gas mixture  the paint system is tested during 3 and 6 months.

Autoclave tests

Over the years, the demand for paint testing at high pressure and temperature in combination with corrosive gases increases. In various standards and specifications such as ISO 15741, EN 10289, EN 10290, ARAMCO 09-SAMSS-067 APCS 27, [...]
