Marine Order 91 (Marine Pollution Prevention - Oil) - Australian Government


You will be required to comply with these guidelines if you intend to operate an Australian ship that has a gross tonnage of 400 or more, or an Australian ship that is an oil tanker with a gross tonnage of less than 400 but not less than 150.

The guidelines provide specifications for the installation of oil discharge monitoring and control systems. The guidelines, developed under technical and scientific guidance, are intended to assist Governments and appropriate authorities, ship masters, operators and owners, and port authorities, as well as other interested parties, in minimising the risk of introducing harmful aquatic organisms and pathogens from ships' ballast water and associated sediments while protecting ships' safety.

Please consult the Contact Officer for more information and to ascertain the level of compliance (if any) that may be required.
