SEEMP Part III — CII Management
Build measurable responsibilities and actions, rather than watching the annual rating alone.
Part III is the operational carbon-intensity plan for relevant ship types ≥5,000 GT; distinguish Part I/II scope.
Rules and bulletins may change. Before operation or voyage, verify the latest official source and ship-specific applicability. This page is not permission, certification or a real-time risk notice.
FOUR-STAGE TOPIC OVERVIEW
Establish applicability, then verify the operation
Scope/plan
Data/annual target
Action/ownership
Review/correction
1 · Separate the three parts
Part I manages energy efficiency; Part II addresses fuel-consumption data collection; Part III is the operational carbon-intensity plan. Check MEPC.395(82) and later amendments rather than relying only on an old 2022 template.
Reference: IMO — MEPC.395(82), 2024 SEEMP guidelines ↗2 · Monitor the ship-specific calculation
Track required/attained CII, applicable capacity, consumption, distance and accepted corrections using the ship method. A–E ratings are not one universal fuel-tonnage target. Do not weaken navigational safety to improve a rating.
Reference: IMO — EEXI and CII FAQ ↗3 · Three-year implementation and ownership
The plan should identify methods to achieve the next three years’ targets, responsibilities, monitoring/self-evaluation and implementation timetable. Assess speed/route optimisation, waiting, hull/propeller condition and consumers with safety and technical suitability.
Reference: IMO — MEPC.395(82), 2024 SEEMP guidelines ↗4 · D/E corrective action
Three consecutive D years or one E year triggers corrective-action planning and SEEMP review/verification. Follow ship/office responsibilities and Administration/RO timing. Obtain future-year factors from current sources as the IMO review progresses.

Six field checks
- Check Part III applicability and verified revision.
- Match required/attained CII and input data.
- Review three-year targets, owners and action schedule.
- Monitor monthly deviations and operational/technical causes.
- Assess D/E triggers and corrective-plan requirements.
- Complete office, Administration/RO and annual evidence chain.
Educational checklist. Completion is not operational/compliance approval; use the relevant vessel permits/forms separately.
Documents to have available
- Verified SEEMP Part III
- IMO DCS/CII data and Statement of Compliance
- Three-year implementation plan
- Self-evaluation and any corrective-action plan
Onboard scenarios
One D year: has the three-D trigger occurred?
No. Check consecutive history and E separately; still monitor deviations.
One E year: can action wait?
One E year triggers corrective-action planning; follow office/Administration procedures.
LEARNING CHECK
Think of your answer, then reveal the explanation
Are Parts II and III identical?
No; data collection and operational carbon planning are different parts.
May navigational safety be sacrificed for CII?
No. Measures must be planned with safety and technical suitability.
Self-assessment only; no exam result, personnel record or competence certificate is generated.
