Frequently Asked Questions

What are PSC deficiency codes?

PSC deficiency codes are a standardised five-digit numbering system used by port state control authorities worldwide to classify findings during ship inspections. The system is harmonised across all major MoU regions (Paris, Tokyo, Indian Ocean, and others) so that a code recorded in Rotterdam means the same thing as one recorded in Singapore.

How many deficiency code categories are there?

There are 19 main categories covering certificates and documentation, structural condition, fire safety, life-saving appliances, pollution prevention, maritime labour standards, and more. Each category contains between 1 and 106 individual codes.

What does detention correlation mean?

Detention correlation is the share of inspections where a particular deficiency was found that also ended in the vessel being detained. It indicates how strongly a deficiency type is associated with detention, but does not imply that the deficiency alone caused the detention.
