Tokyo MOU published its Annual Report for 2023, indicating that 30,887 inspections, involving 18,298 individual ships, were carried out on ships registered under 101 flags.

Out of 30,887 inspections, there were 18,806 inspections where ships were found with deficiencies. Since the total number of individual ships operating in the region was estimated at 27,544, the inspection rate in the region was approximately 66% in 2023.

The concentrated inspection campaign (CIC) on Fire Safety was conducted from 1 September to 30 November 2023 jointly with the Paris MoU.

During the CIC period, a total of 8,273 PSC inspections were conducted by the member Authorities, of which 7,190 (86.91%) were with a CIC inspection.

A total of 2,860 CIC-related deficiencies were found on 1,287 ships representing 17.90% of the CIC inspections.

The highest compliance was observed on means of control for power ventilation of machinery spaces operable from two grouped positions with 99.69% positive result, which indicates a high level of compliance in this area.

The highest levels of non-compliance were found on fire drills, where 8.44% of those drills, witnessed as part of the CIC, were unsatisfactory. 88 ships subject to the CIC inspection were detained as a direct result of the campaign.

Comparing the 1.22% CIC related detention rate and the 3.77% overall detention rate during the period, the outcome of the CIC indicates a high level of compliance with fire safety areas related to the CIC.

In 2023, 1,334 ships registered under 71 flags were detained due to serious deficiencies having been found onboard. The detention rate of ships inspected was 4.32%.


Where conditions on board are found that are not in compliance with the requirements of the relevant instruments by the port State control officers, these are recorded as deficiencies and required to be rectified.

A total of 75,867 deficiencies were recorded in 2023. The deficiencies found are categorized and shown in Figure 7 and Table 7.

In addition, categories of deficiencies on life-saving appliances, propulsion and auxiliary machinery, MARPOL Annexes I, IV and VI increased substantially in 2023.
