The "Port state control" section gathers a vessel's entire PSC history in one place — headed by the detention verdict, e.g. "Zero detentions since 2023".
What you see
- The summary: total inspections and the date of the last one, deficiencies and detentions over 3 years, lifetime detentions, average deficiencies per visit, and the MoU band.
- A reduced-intervals banner for vessels with a clean record: White-band ships are inspected less often.
- The last five inspections with dates, ports, deficiency counts and outcomes — after free registration.
- Regulatory risk bands from the registry — Paris MoU and Tokyo MoU bands, USCG targeting, the society's IACS membership — for members.
The MoU band in the summary is marked "estimated" when the vessel has no registry band and it is derived from inspection statistics.
Why it helps
PSC history is a signal of a vessel's technical condition and its risk of being detained in port.
How to get every deficiency line by line
Under the inspections table sits the "Order the report" button: the full inspection report carries every deficiency across all inspections plus ship certificates with their validity dates. A vessel with zero deficiencies does not show the button.
