SEEMP Part II and Part III
SEEMP connects energy management, DCS data collection and CII planning through three parts with distinct scopes, verification and update requirements.
Operational Explanation
Part I organises energy-efficiency improvement. Part II describes DCS collection and reporting methods. Part III plans the ship’s CII performance. A useful plan lets the reader trace a reported figure back to its onboard measurement, and an improvement measure to the person responsible for implementing it.
In Part II also document reconciliation of total distance with its under-way and not-under-way components: MEPC.413(84), adopted on 1 May 2026, clarifies that both enter the annual total and adds separate reporting rows. Update the method and data mapping with the verifier so that a partial field is not reported as the total. SEEMP, 7.7.2 and Appendix 4.
Regulatory Reference
Scope of Application
Within chapter 4, subject to regulation 19 exclusions: Part I from 400 GT; Part II from 5,000 GT for ships subject to regulation 27; Part III from 5,000 GT only for the categories listed in regulations 26.3 and 28.1. DCS participation alone does not establish a Part III obligation.
Procedure / How to Complete It
- Determine applicability of each part separately using the ship’s particulars and category.
- In Part II document methods, responsibilities, quality checks and missing-data procedures for the applicable DCS fields.
- In Part III maintain required CIIs for the next three years and the measures planned to achieve them; record reviews and changes.
- Following three consecutive D ratings or one E rating, incorporate a corrective-action plan. Submit the revised SEEMP for verification within one month after reporting attained annual CII.
- Retain the relevant plan and verification confirmations. Distinguish the plan’s Confirmation of Compliance from the annual DCS/CII Statement of Compliance.
Practical Example
Training example. The shore manager finds a difference between reported annual consumption and onboard totals. Before changing CII targets, they reconstruct the Part II data trail. They then check whether Part III measures were actually implemented: correcting a figure and improving performance are different activities.
What Typically Goes Wrong
A file updated only on its cover may retain obsolete collection methods or measures without an owner. Document review should also establish whether the plan reflects onboard practice.
Common Mistakes
| Mistake | Consequence | How to Avoid It |
|---|---|---|
| Conflating Parts II and III | DCS methodology and CII planning are not checked against their respective scopes | Record applicability and documents separately. |
| Treating any class signature as statutory verification | The organisation’s mandate has not been established | Identify the Administration or its duly authorised organisation. |
What the PSCO Checks
Prepare the SEEMP required for the ship, its relevant confirmations and the applicable annual Statement of Compliance. Check consistency of ship identity, the revision in use and, where required, the verified corrective-action plan. These are not three names for the same certificate.
Operational Tips
- Assign onboard and shore contacts to reconcile versions.
- Keep a change log identifying the reason, date and superseded documents.
- Assess the effectiveness of measures before year-end; do not present a company monitoring interval as a universal IMO requirement.
Preparation checklist
- Applicability of each part documented.
- DCS methods match the data collected.
- Three-year CII plan relevant to the ship.
- Rating history and need for corrective action checked.
- Plan confirmations and annual statement identified separately.
