Tokyo MOU: Regional Specificities
The 2025 BWM CIC is historical; the 2026 joint Paris/Tokyo campaign concerns Cargo Securing, while BWM compliance remains permanent.
Operational Explanation
The 2025 Ballast Water Management CIC has ended and its results are historical. BWM compliance remains permanent, but an ended campaign does not itself prove enhanced targeting in 2026.
Regulatory Reference
Tokyo MOU (Memorandum of Understanding on Port State Control in the Asia-Pacific Region): the same risk-based targeting principles as the Paris MoU, with its own Annual Report and a CIC calendar partly coordinated, partly distinct.
Where the power to come on board comes from. Not from the Memorandum. A regional MoU is an administrative arrangement between Administrations: it harmonises how inspections are done, it does not create the right to inspect. That right sits in the control articles of the Conventions, which resolution A.1206(34) — Procedures for Port State Control, 2025 — lists one by one at its paragraph 1.4. For SOLAS there are four regulations, not one: I/19, IX/6.2 (ISM), XI-1/4 and XI-2/9 (ISPS). For MARPOL, Articles 5 and 6 plus one provision per Annex: reg. 11 of Annex I, reg. 16.9 of II, reg. 9 of III, reg. 14 of IV, reg. 9 of V and reg. 10 of VI. The “reg. 9 of III” surprises anyone who opens Annex III in the text adopted by res. MEPC.193(61), where port State control on operational requirements is Regulation 8: res. MEPC.246(66), in force from 1 January 2016, inserted a new Regulation 1 “Definitions” into it and provided that “the subsequent regulations are renumbered accordingly”. Since 2016 that provision has been Regulation 9, and that is the number A.1206(34) carries. Then Article 21 of the Load Lines Convention 1966 as modified by the 1988 Protocol, Article X of STCW, Article 12 of TONNAGE 1969, Article 11 of AFS 2001 and Article 9 of BWM 2004. For the MLC, an ILO and not an IMO instrument, the basis is Regulation 5.2.1 with Standard A5.2.1.
The practical consequence is that challenging an inspection on the ground that your flag State is not party to the Memorandum leads nowhere: the inspector is not acting under the Memorandum, but under the control article of the Convention the flag State has ratified.
Scope of Application
Every ship calling at ports of Tokyo MOU member States (Asia-Pacific region, including Japan, Australia, China, South Korea, Singapore and others).
Procedure / How to Complete It
- Check the Tokyo MoU current calendar and circulars.
- Separate permanent obligation from temporary campaign.
- Use 2025 results as history, not a current targeting notice.
- Prepare for the applicable 2026 CIC from the current notice and questionnaire.
Practical Example
Example of preparation: a ship operating regularly between Paris MoU and Tokyo MOU ports checks, ahead of the 2025 Concentrated Inspection Campaign on Ballast Water Management, the correct functioning of its own BWMS with particular attention, knowing this was the most common deficiency found during the campaign.
What Typically Goes Wrong
Common Mistakes Mistake Library
| Mistake | Consequence | How to avoid it |
|---|---|---|
| Uncritically applying Paris MoU statistics and priorities to port calls in the Tokyo MOU region | Preparation not calibrated to the real regional specificities | Always consult the specific Tokyo MOU Annual Report, not only the Paris MoU's |
| Underestimating the relevance of BWMS functioning ahead of inspections in the Asia-Pacific region | Deficiency in the category most frequently found in recent campaigns | Prioritise verification of the ballast water management system before port calls in this area |
| No specific monitoring of the Ship Risk Profile calculated by the Tokyo MOU | Surprise at the inspection frequency expected in the region | Monitor the Tokyo MOU Ship Risk Profile separately from the Paris MoU's |
What the PSCO Checks
Operational Tips
- Always consult the region-specific Tokyo MOU Annual Report, don't rely only on Paris MoU statistics.
- Prioritise verification of the ballast water management system before port calls in the Asia-Pacific region.
- Monitor the Ship Risk Profile calculated specifically by the Tokyo MOU for ships operating in this area.
Preparation checklist
- Current calendar checked
- 2025 CIC labelled historical
- BWM retained as permanent duty
- 2026 CIC checked against current source
