MARPOL Explained: A Practical Guide to IMO's Pollution Regulations

In the global shipping industry, environmental responsibility is governed by one primary international convention: MARPOL. As the cornerstone of marine pollution prevention, understanding the International Convention for the Prevention of Pollution from Ships (MARPOL) is essential for every shipowner, operator, and seafarer.

What is MARPOL? The Six Annexes Explained

MARPOL 73/78 is divided into six technical Annexes, each addressing a specific category of marine pollution. A ship must adhere to the Annexes of the states whose flag it flies.

• Annex I: Prevention of Pollution by Oil
• Annex II: Control of Pollution by Noxious Liquid Substances in Bulk
• Annex III: Prevention of Pollution by Harmful Substances Carried by Sea in Packaged Form
• Annex IV: Prevention of Pollution by Sewage from Ships
• Annex V: Prevention of Pollution by Garbage from Ships
• Annex VI: Prevention of Air Pollution from Ships

Enforcement: The Role of Port State Control (PSC)

Port State Control Officers (PSCOs) are responsible for inspecting foreign ships in national ports to verify compliance with international conventions like MARPOL. If clear grounds for a violation are found, the PSC can detain the ship until the deficiencies are rectified.
