EEXI & CII SERVICES

Technical Update – June 2021
Services pertinent to EEXI – CII compliance

Amendments to MARPOL Annex VI: finding the best way to comply.

The International Maritime Organization (IMO) has recently decided to reduce the carbon intensity of international shipping. In this frame, the following amendments to MARPOL VI, were adopted during MEPC 76, in June 2021:

  • Implementation of specific technical measures to reduce carbon intensity, as prescribed by the new Energy Efficiency Existing Ship Index (EEXI)
  • Specification of operational carbon intensity reduction measures, as prescribed by the new operational Carbon Intensity Indicator (CII)

The integrated new approach thus includes both technical and operational measures.

Energy Efficiency Existing Ship Index (EEXI) Attained and Required

It is mandatory to calculate the attained Energy Efficiency Existing Ship Index (EEXI) for all ship types of 400 GT and above. This value should not exceed the required value of EEXI, to be calculated following the guidelines of the new regulation. A final EEXI Technical file should be prepared for each vessel and submitted to Flag or RO, leading, after an onboard survey, to the issuance of a new International Energy Efficiency Certificate (IEEC). Ships should be EEXI-compliant by the first survey of the IEEC on or after January 1st, 2023.

Annual operational Carbon Intensity Indicator (CII) – CII rating  

All ships of 5,000 GT and above will be subjected to the calculation of the annual operational Carbon Intensity Indicator (CII), which will determine the required carbon intensity reduction on an annual basis.

The attained CII will be recorded in the amended Ship Energy Efficiency Management Plan (SEEMP) and must be approved by the Flag or RO. Submission of an alternative action plan will be mandatory for low-rated ships, in order to comply with the required level of carbon intensity rating.

EEXI SERVICES

The services offered are based on an accurate, efficient, and automated procedure, which makes use of own-developed specialized software, Ship-EEXI, to perform the relevant calculations and produce the final EEXI Technical File.

Standard Services

  1. Calculation of current EEXI.
  2. Calculation of required EEXI.
  3. Calculation of suggested Engine Power Limitation (EPL) / Shaft Power Limitation (SHaPoLi)
    to achieve the required EEXI, considering requirements for minimum propulsion power.
  4. Calculation of suggested new reference speed based on the suggested limited MCR.
  5. Calculation of attained EEXI based on onboard EPL / SHaPoLi installation (limited MCR).
  6. Completion of the final EEXI Technical File.

Additional (Optional) Services

  1. Preparation of EPL / SHaPoLi Onboard Management Manual (OMM).
  2. Characterization of vessel’s competitiveness based on the suggested new reference speed and actual data of vessel’s speed profiles.
  3. Assessment of technical measures to reduce carbon intensity:
  • Shaft Generator (PTO)
  • Hull air lubrication system
  • Wind assisted propulsion (applicable to tanker & bulk carrier vessels)
  • Waste heat recovery
  • Photovoltaic cells
  1. Evaluation of Energy Efficiency Technologies (EETs) / Feasibility Study pertinent to a particular EET or combination of EETs.
  2. Specialized services as CFD calculations in the frame of speed-power curve estimation.

CII SERVICES

  1. Calculation of attained CII based on vessel’s authorized data.
  2. Calculation of required CII.
  3. Determination of the vessel’s operational carbon intensity rating (CII rating).
  4. Preparation of vessel’s new/amended SEEMP.
  5. Technical support for the development and implementation of operational measures for reducing carbon intensity in non-compliant vessels.

 

Responding to the adopted mandatory IMO requirements, M&C Group and SHIPREALITY have joined forces to offer quality services to shipping companies and support them in implementing pragmatic solutions for ship energy efficiency.
