Implementation
The requirements for the treatment of ballast water, the D-2 standard requiring the installation of a ballast water treatment system, entered into force 8 September 2024.
Exemptions
The concept of "Same Risk Area", developed in Denmark, has now been approved by the IMO. This means that, rather than making a risk assessment per ship route, you can make a risk assessment for minor sea areas (following agreement among the authorities of all the countries affected); this would be considerably easier to handle for both shipowners and the authorities.
Type approval
Ballast water treatment systems are type-approved according to IMO guidelines (G8), and ships calling at US ports are type-approved according to a USCG procedure. Ballast water treatment systems approved according to G8 by 28 October 2018 may be installed on board ships by 28 October 2020.
The Code for approval of ballast water treatment systems (BWMS Code) must be used for type-approvals after 28 October 2018, at the latest, and systems installed on board ships must have been approved according to the code after 28 October 2020.
On-going work in the IMO – Experience Building Phase
The work future-proving the convention has been initiated, and it is expected that it will be possible to adopt a revised text – based on experience retrieval – in 2026.
