PSC deficiency checklist generator
Port State Control records deficiencies against a standardised set of categories. Pick a ship type and this builds a preparation checklist organised by those same Paris MoU categories, filtered to what applies to your ship. The tool runs in your browser — nothing you select is sent anywhere.
Selecting a ship type hides items that do not apply and keeps every item common to all ships. Showing all 81 items.

Categories and code ranges are taken from Paris MoU — Overview of Deficiency Codes (1 July 2025). This is not a Paris MoU product and carries no endorsement, and it reproduces no proprietary inspection question set. It is a preparation aid built on the publicly published code structure. The inspection and any detention decision are the port State authority’s alone.
Questions
What is a Port State Control deficiency code?
Port State Control regimes record every deficiency found during an inspection against a standardised code. The Paris MoU groups these into categories such as certificates and documentation, fire safety, life-saving appliances, safety of navigation, ISM and MLC. This checklist is organised by those official categories so a ship can prepare against the same structure an inspector uses.
Which deficiencies can lead to a detention?
A deficiency becomes grounds for detention when it is serious enough that the ship, once at sea, would present a danger to safety, health or the environment. Areas that frequently carry that weight include ISM, fire safety, life-saving appliances and safety of navigation — but detention is a judgement made by the attending officer on the specific finding, not a fixed list. Treat every item here as preparation, not a guarantee.
Does this checklist send my ship data anywhere?
No. The tool runs entirely in your browser. The ship type you select is never transmitted, logged or stored, and there is no account or sign-in.
Is this an official Paris MoU tool?
No. This is an independent preparation aid built on the publicly published Paris MoU deficiency-code categories. It is not a Paris MoU product and carries no endorsement. The inspection, the deficiency assessment and any detention decision are the port State authority’s alone.
Does the same structure apply under Tokyo MoU or the USCG?
The deficiency-code categories used here are the harmonised scheme shared across the main Port State Control regimes, so the structure is broadly applicable under Tokyo MoU and, in substance, US Coast Guard inspections. The detention criteria and campaign priorities differ by regime — confirm the current requirements for the port you are entering.
