Principle of Port State Control (PSC)
In addition to a ship's country of registration (the "Flag State" ), any other country a ship visits is considered a "Port State." It's the Flag State's primary duty to ensure that a ship flying its flag is safely constructed, properly equipped, adequately maintained, and sufficiently manned as per regulations based on International Maritime Organization (IMO) conventions. To achieve this, the Flag State conducts surveys and inspections on vessels under its registry for the issuance of various statutory certificates.
However, many ships may not call at their home ports for considerable periods. Therefore, it's crucial that ships are inspected at various ports to ensure ongoing compliance with requirements related to safety, maintenance, manning, and pollution prevention. This system of inspection and enforcement by a country in its ports on foreign-flagged ships is termed Port State Control .
