An IOPP is required on non-tank vessels of what size?

The International Oil Pollution Prevention (IOPP) Certificate is an essential document that helps in regulating discharges into the marine environment from non-tank vessels. For non-tank vessels, the requirement for an IOPP Certificate applies specifically to those that are 400 gross tonnage (GT) and above.

This requirement stems from international conventions aimed at preventing oil pollution from ships, and it establishes not just a regulatory framework, but also promotes best practices in managing oil residues and discharges. The stipulation of 400 GT ensures that larger vessels, which have a higher capacity for carrying fuel and oil, are subject to stringent environmental regulations, ultimately aimed at minimizing the risk of oil spills and protecting marine ecosystems.

It’s important for marine science technicians to understand this threshold, as it affects compliance inspections and the implementation of operational practices on board these vessels. Smaller vessels, under 400 GT, are not subject to the same IOPP Certificate requirements, reflecting a tiered approach to regulatory oversight based on vessel size and potential environmental impact.
