For how long is an International Oil Pollution Prevention (IOPP) certificate valid?

The International Oil Pollution Prevention (IOPP) certificate is critical for vessels as it demonstrates compliance with international regulations aimed at preventing oil pollution from ships. This certificate is typically valid for a period of 5 years. During this validity period, the vessel is subject to regular inspections to ensure ongoing adherence to the necessary standards.

After the initial issuance, the IOPP certificate must be renewed or reissued, which often involves further inspections to confirm that the vessel's systems remain fully operational and in compliance with International Maritime Organization (IMO) regulations. This duration aligns with the general practices of certification in maritime operations, aiming to ensure that vessels are regularly assessed for safety and environmental standards.
