International Maritime Organisation (IMO)

The International Maritime Organisation (IMO)is an agency of the United Nations established in 1948 by a convention which came into force in 1958. Today it has 158 Member States plus two Associate Members.

The Organisations chief task, especially in the early years, was to develop a comprehensive body of international conventions, codes and recommendations in the area of International shipping, particularly shipping safety, which could be implemented by all Member Governments.

Sea Pollution

The Sea Pollution Act 1991 provides for the regulation, amongst other things, of sewage and garbage arising from offshore installations. The discharge of domestic sewage is permitted but best practice would include reduction of gross solids e.g. by means of maceration of solids prior to discharge.

General Information

The goal of the Marine Environment section is to preserve and protect the quality of the marine environment through prevention of marine pollution from vessels.

This is done by adopting, implementing and updating primary and secondary legislation in accordance with accepted international standards to secure a clean marine environment, and by promoting awareness of the marine environment.
