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

Monday, September 22, 2014 7 Summary of Approval Pathway Basic Approval is the first step in the approval process when using an active substance. Basic Approval is thus an ‘in principle’ approval of the environmental impact of an active substance. It allows testing of a system at sea. Treatment system will be tested both on land-based and shipboard ship according to IMO Guideline G(8). A standard playing field has been designed to evaluate the efficacy of treatment system by G(8). Both land-based and shipboard tests are supervised by Flag State or its representative

Approval procedure in G(8) A shipboard test cycle should include: The uptake of ballast water of the ship; The storage of ballast water on the ship; Treatment of the ballast water in accordance with: The amount of ballast water tested in the test cycle onboard should be tested st the Treated rated Capacity. The discharge of ballast water from the ship. Valid tests are indicated by uptake water: Viable organisms in both control and ballast tanks should be more than 10 times the values of regulation D-2.1. Viable organisms of control tank should be more than the values in the Regulation D-2.1
