Preparing for Flag & Port State Control

30 Jul 2026 · Candour Marine Assurance Team

The flag administration oversees ships registered under its flag. Port State Control (PSC) checks foreign ships visiting a port. Neither is replaced by an independent preparation review.

Preparing for Flag & Port State Control

Start with the essentials

Documents: certificates, crew records, rest hours and maintenance history.

Equipment: lifesaving, firefighting, navigation and pollution-prevention systems.

People: emergency duties, drills and familiarity with equipment.

Follow-up: previous deficiencies, repairs and checks on completed work.

Brief the ship and shore team

Agree who will provide documents, accompany the inspector and record findings. Raise outstanding defects with management before the inspection.

Confirm requirements with the relevant flag administration or PSC authority. Class surveys are a separate process coordinated with the vessel's classification society.
