🔍 Key Concepts

• IOPP Certificate (International Oil Pollution Prevention Certificate) purpose and what conditions must be maintained for it to stay valid • Typical reasons a statutory certificate becomes invalid (change of flag/registry, major non‑compliance, survey schedule problems, equipment not meeting required standards) • MARPOL Annex I requirements for oily-water separators and discharge standards (e.g., 15 ppm limit)

💭 Think About

• For each option, ask: Would this situation mean the ship no longer meets the conditions under which the IOPP Certificate was issued? • Think about what happens to certificates when a ship changes flag or misses a required survey window. • Compare the pollution prevention performance of a 15 ppm separator versus a 100 ppm separator: which is stricter, and how might that affect compliance with MARPOL limits?

✅ Before You Answer

• Identify which events automatically cancel or require re-issuance of statutory certificates (such as change of flag or missing survey windows). • Check whether a temporary equipment malfunction automatically invalidates the certificate, or simply requires repair and possible notification/inspection. • Verify which oily-water separator performance level (15 ppm vs 100 ppm) meets MARPOL Annex I discharge requirements and whether installing a less protective system would keep the vessel in compliance.

In which case is the IOPP Certificate of an inspected vessel NOT invalidated?

The required oily-water separator malfunctions.

The ship is transferred to Liberian registry.

An annual survey is conducted fifteen months after the date of certificate issuance.

A 15 ppm oily-water separator is replaced by a 100 ppm oily-water separator.
