An IOPP Certificate is required for non-tank vessels over what gross tonnage?

The International Oil Pollution Prevention (IOPP) Certificate is a key requirement established under the MARPOL Convention, specifically aimed at preventing the pollution of the marine environment by oil from ships. For non-tank vessels, the regulation specifies that vessels with a gross tonnage above 400 GT must possess an IOPP Certificate. This requirement is part of the broader effort to ensure that all vessels adhere to standards that mitigate the risk of oil spills and other pollution incidents at sea.

Understanding this requirement is crucial for compliance with international maritime regulations, as vessels meeting the gross tonnage threshold must demonstrate adequate oil pollution prevention measures. This includes having proper operational procedures in place and maintaining equipment that prevents oil discharge into the ocean, thereby safeguarding marine ecosystems and following international guidelines.
