What is Marpol Annex 9?

 

[🤖]

MARPOL Annex 9 refers to the International Convention for the Prevention of Pollution from Ships (MARPOL), which is an important international maritime agreement. Annex 9 specifically addresses the requirements for the survey and certification of anti-fouling systems on ships.

Anti-fouling systems are coatings or other treatments applied to the hulls of ships to prevent the accumulation of marine organisms, such as barnacles and algae, which can increase drag and fuel consumption, as well as potentially introducing invasive species to new environments.

MARPOL Annex 9 sets out the guidelines and regulations for the application, inspection, and certification of anti-fouling systems on ships. It aims to ensure that these systems are used in a safe and environmentally friendly manner, with a focus on preventing the release of harmful substances into the marine environment.

The annex requires that ships using anti-fouling systems must be surveyed and certified by the flag state or an authorized organization. The validity of the certificate is generally limited to a maximum of five years, and regular inspections are required to ensure ongoing compliance.

By implementing the requirements of MARPOL Annex 9, the International Maritime Organization (IMO) seeks to minimize the impact of anti-fouling systems on the marine environment, while still allowing for their effective use in maintaining ship performance and efficiency.
