Ship Energy Efficiency Management Plan (SEEMP)-Part III

Jan. 24, 2023

The Ship energy efficiency Management Plan provides a practical approach for ship operators and management companies to manage operations and fleet efficiency performance over time using the Energy Efficiency Operational Indicator (EEOI) as a monitoring tool. And it is implemented according to the ship type, cargo carried, ship routes, and other relevant factors.


  • To encourage companies to incorporate actions to improve the energy efficiency and carbon intensity of their ships and ship management practices and
  • To specify the methodology the ship should use to collect the data required by regulation 27.1 of MARPOL Annex VI and the processes that should be used to report the data to the Administration of ship or any organization duly authorized by it.
  • To specify the methodology the ship should use to calculate the attained annual operational carbon intensity indicator (CII) as required by regulation 28.1 of MARPOL Annex VI and the processes that should be used to report the data to the ship’s administration or any organization duly authorized by it.

The basics of creating the SEEMP for a particular ship are to estimate and determine the current energy consumption of the vessel and implement various measures to reduce the same.

SEEMP: Key Features

● Broader Corporate energy management policy

● Enhancement of ship efficiency

● Reduction in fuel consumption

● A decrease in GHG emissions from the vessel

SEEMP :Onboard Measures

SEEMP is ship specific plan which can be efficiently implemented on vessels in 4 steps:

1. Planning

2. Implementation

3. Monitoring

4. Self-evaluation and improvement


A verified SEEMP Part III containing Ship Operational Carbon Intensity Plan will serve as the implementation plan for achieving the required CII. This dynamic plan will be amended and revised to achieve the CO2 reduction rating; hence, unlike SEEMP 1, it will be subject to verification and company audits.

Requirement for SEEMP III

  • It should include the methodology used for calculating the CII and how to report it.
  • It has to be kept onboard from 1 January 2023 to document how you plan to achieve your  CII targets
  • A 3-year implementation plan documenting how the required CII will be achieved during the next 3 years, with yearly targets
  • Procedures for self-evaluation and improvement
  • The required CII for the next three years, calculated based on the individual vessel’s specifications
  • Corrective action plan in case of inferior rating
  • Collecting annual fuel data from 1 January to 31 December
  •  Verification of the reporting data, including the CII rating result, and issuance of a Statement of Compliance by the Administration or an RO
  • Company audits on SEEMP Part III within six months after issuing the Statement of  Compliance.
  • Access to the disaggregated data that underlie the reported data. It should also be noted that the new SEEMP III comes in addition to the SEEMP I and SEEMP II and will be handled as a separate document.

SEEMP III : Operational Measures

The SEEMP III intends to ensure continuous improvement, and its implementation will be subject to company audits. A vessel can reduce its carbon intensity by a combination

of measures:

● Speed optimisation

● Optimisation of operations and logistics

● Implementation of energy efficiency technologies

● Voyage optimisation

● Effective maintenance management

● Alternate fuel
