What is ISO 21963 about?
ISO 21963 is an International Standard on ships and marine technology.
ISO 21963 provides requirements and test methods for tanks, piping and separation systems facilitating the separation of contaminated fluids of oil and water on fixed offshore marine structures and ships, where treatment is performed by separation systems that optimize oil-water separation to a concentration equal to or less than 5 ppm.
ISO 21963 applies to fixed offshore marine structures and ships operating in designated sea areas determined by the relevant authorities. BS ISO 21963:2020 history
