CII (Carbon Intensity Indicator)
CII applies only to the closed MARPOL VI/28.1 categories from 5,000 GT; a D/E rating requires revised SEEMP Part III with a corrective-action plan submitted for verification, not generic class approval.
Operational Explanation
CII applies only to the closed MARPOL VI/28.1 categories from 5,000 GT; a D/E rating requires revised SEEMP Part III with a corrective-action plan submitted for verification, not generic class approval.
Regulatory Reference
MARPOL Annex VI regulations 26.3, 28; MEPC.395(82).
Scope of Application
DCS threshold is broader; general passenger ship is not a standalone CII category.
Procedure / How to Complete It
- Check the listed 28.1 ship category and GT.
- Calculate attained/required CII and rating under current guidelines.
- For D three years or E one year prepare corrective-action plan.
- Submit revised Part III to Administration/duly authorised organisation within 28.8.
- Retain Confirmation of Compliance; do not invent a 2026 PSC campaign.
Practical Example
A D/D/D ship updates Part III and obtains verification/Confirmation without calling it universal class approval.
What Typically Goes Wrong
Writing all cargo and passenger ships ≥5,000 GT, formal approval, or universal PSC focus from 2026.
