The Paris and Tokyo MoUs on port state control are launching a joint check on navigational safety this autumn.
The concentrated inspection campaign (CIC) wants to improve standards by assessing compliance with the SOLAS convention and the competence of crew.
About 10,000 ship inspections will be carried out between 1 September and 30 November, the port state organisations said.
Inspectors will use a checklist of 12 questions.
