Nowadays dramatic examples of the devastation caused by invasive species on the marine wildlife are all too easy to find. The most effective way to limit the spread of ballast water invasive species is to prevent their introduction.
The International Maritime Organisation (IMO) introduced in 2004 the Ballast Water Convention (BWC) to address the Control and Management of Ships’ Ballast Water and Sediments for all sea going ships greater than 400gt using ballast water.
The BWMC entered into force 8th September 2017. Ships are required to manage their ballast tanks to remove or render harmless the ballast water discharge of invasive species.
