These guidelines are designed to ensure that such technologies meet the relevant IMO standards: are sufficiently robust; have minimal adverse environmental impact; and are suitable for use in the specific shipboard environment. A company offering a treatment process must have the process approved by a Flag Administration. In general the manufacturer will use: the country in which it is based the Flag State where the testing facility is based
