Building Trust: Independent Emissions Verifier

SEEMP Part II & III Verification

SEEMP Part II & III Verification 

First introduced by the IMO in 2013 and updated in 2023, the Ship Energy Efficiency Management Plan (SEEMP) serves as a structured and practical framework to help shipowners enhance environmental performance and operational efficiency. 

The SEEMP is divided into three parts: 

  • Part I: Ship management plan to improve energy efficiency 
  • Part II: Fuel oil consumption data collection plan 
  • Part III: Operational carbon intensity plan

SEEMP Part II: Fuel oil consumption data collection plan 

To support the shipping industry’s transition to a low-carbon future, the IMO has continuously strengthened its regulatory framework on fuel consumption monitoring and energy efficiency. One of the most significant updates to this framework came during the 82nd session of the Marine Environment Protection Committee (MEPC), where Resolution MEPC.395(82) was adopted. SEEMP Part II, as outlined in MEPC.395(82), is required to enhance the accuracy and transparency of fuel oil consumption reporting for ships. This regulation is part of the International Maritime Organization’s (IMO) broader strategy to reduce greenhouse gas emissions from international shipping.

Collection of data for existing ships after 1 August 2025  

Ships that hold a verified SEEMP Part II and are collecting the data within the current MARPOL Annex VI Appendix IX before 1 August 2025, are expected to continue collecting this data after 1 August 2025 until 31 December 2025. This is to ensure that the data collected and reported is consistent throughout the calendar year. In any case, these ships will be required to collect the additional data in the Annex to MEPC.395(82) from 1 January 2026.  

Collection of data for new ships after 1 August 2025  

For ships that enter service and start collecting data on or after 1 August 2025, it is expected that such ships will collect the data (including the additional data) in the Annex to MEPC.395(82) as they had not collected any data before the amendments entered force. 

Key Additions in the New SEEMP II (MEPC.395(82))  

  1. Transport Work:The revised Appendix IX has introduced a new requirement for explicit cargo reporting to facilitate accurate calculation of transport work. The definitions of cargo units have been harmonized with IMO regulatory frameworks 
  2. Power Demand at Berth:Track average power use while at berth. – Report berth duration and use of shore power.  
  3. Fuel by Emission Source:Separate reporting for main engines, auxiliary engines, and boilers, IGG etc.  
  4. Revised Definition of “Under Way” –MEPC 83 Update – MEPC 83 revised the definition of “under way” to include mandatory reporting of BOSP (Begin of Sea Passage) and EOSP (End of Sea Passage) events. 

Detailed Process 

SEEMP III: Operational carbon intensity plan 

A mandatory, ship-specific plan to improve CII and energy efficiency over three years. It must be updated regularly, verified, and kept on board with a Confirmation of Compliance (CoC) from 1 January 2023. 

Verification of SEEMP Part III 

SEEMP Part III must include: 

  • The required CII for the next three years, calculated according to the vessel’s particulars. 
  • The target CII for the next three years, based on planned operational measures. 
  • An implementation plan detailing how the required CII will be achieved over the three-year period. 
  • Procedures for self-evaluation and continuous improvement. 
  • A Corrective Action Plan, if applicable, in case of a “E” CII rating. 
SEEMP Part III Revisions Required 

All ships with an approved SEEMP Part III (Ship Operational Carbon Intensity Plan) must revise the document to include an implementation plan showing how the required CII will be achieved for the period 2026–2028. This update is in line with the Guidelines for the Verification and Company Audits by the Administration of Part III of the SEEMP (MEPC.347(78)).

Process

  1. Initiate Contact

    The clients initiate the contact by contacting the Normec Verifavia’s Team. 

  2. Preparation of SEEMP Plans

    The client prepares the SEEMP II & III plans in line with the MEPC.395(82) guidelines, incorporating all recent amendments. Once finalized, the plans are submitted to Normec Verifavia. 
     

  3. Verification & Analysis

    Verifiers review the plans and confirm that they meet the requirements of the MEPC.395(82) guidelines. 
     

  4. Completion of Verification

    Following the review process, the plans are submitted to the appropriate Class/RO or Flag, which is responsible for issuing the COCs. For vessels under Antigua & Barbuda and St. Kitts & Nevis flags, the COCs are issued directly by us, since we are fully delegated by these administrations.

FAQ

Find answers to the most commonly asked questions

What are the new requirements under SEEMP Part II (MEPC.395(82))?

Key updates include: 

  • Explicit cargo reporting for transport work. 
  • Monitoring of power demand at berth (including shore power usage). 
  • Separate fuel reporting by emission source (main engines, auxiliaries, boilers, IGG, etc.). 
  • Revised definition of “under way,” including mandatory BOSP and EOSP event reporting. 

When do the new SEEMP II requirements take effect?

  • Existing ships: Continue reporting current data until 31 Dec 2025, then add new requirements from 1 Jan 2026. 
  • New ships (post 1 Aug 2025): Must comply with the new Annex (MEPC.395(82)) immediately. 

What are the SEEMP III audit requirements?

Liberia (MA 15/2025): 

  • Periodical 3-year company audit. 
  • Company audit if any vessel is rated “E” (must be completed by 30 Nov of following year). 
  • Company audit if vessel is rated “D” for 2 consecutive years; Shipboard audit if rated “E” for 2 consecutive years.

Panama (MMC-365): 

  • Shipboard + company audits if any vessel is rated “E” in a reporting year or “D” for 3 consecutive years. 

Other flags: 

  • Typically require shipboard or company audits for vessels rated “E” in a reporting year or “D” for 3 consecutive years.
     

What happens if a vessel consistently receives poor CII ratings?

  • A Corrective Action Plan must be included in SEEMP Part III. 
  • Flag administration may mandate company or shipboard audits.
     

Does SEEMP III needs to be verified every three years?

If a vessel has not received any inferior ratings (i.e., one “E” or three consecutive “D” ratings), then at the end of the three-year period the company must submit a revised three-year implementation plan. This plan should outline how the required CII will be achieved over the next three years, include annual targets, and define procedures for self-evaluation and continuous improvement.
