WHAT IS THE IMO?

The IMO’s main role is to create a regulatory framework for the shipping industry that is fair and effective, universally adopted and universally implemented. The IMO carries the responsibility for the safety and security of shipping and prevention of marine and atmospheric pollution by ships. 

THE IMO AND ITS CONVENTIONS

THE IMO BALLAST WATER CONVENTION CAME INTO FORCE ON 8TH SEPT 2017
The first IMO convention entered into force in 1958 and has established several treaties since then to provide safety at sea. The majority of conventions adopted under the IMO or for which the organisation is otherwise responsible fall into three main categories; maritime safety, prevention of maritime pollution and liability and compensation. The convention affects approximately 60,000 vessels around the world ensuring that they will all have BWTS installed by 7th September 2024
