IMO’s Marine Environment Protection Committee (MEPC 76), meeting in June 2021, adopted amendments to the International Convention for the Prevention of Pollution from Ships (MARPOL) Annex VI that will require ships to reduce their greenhouse gas emissions.
The Carbon Intensity Indicator (CII) will be required for Cargo, Cruise and From 2023, the CII requirements will take effect for all cargo, RoPax and cruise vessels above 5,000 GT and trading internationally.
The new measures will require all ships to calculate their Energy Efficiency Existing Ship Index (EEXI) following technical means to improve their energy efficiency and to establish their annual operational carbon intensity indicator (CII) and CII rating. Carbon intensity links the GHG emissions to the amount of cargo carried over distance travelled.
Ships will get a rating of their energy efficiency (A, B, C, D, E – where A is the best). Administrations, port authorities and other stakeholders as appropriate, are encouraged to provide incentives to ships rated as A or B also sending out a strong signal to the market and financial sector.
The performance level will be recorded in the ship’s Ship Energy Efficiency Management Plan (SEEMP).
To fulfill the EEXI, there are many things a ship can do to improve its rating through various measures, such as hull cleaning to reduce drag; speed and routeing optimization; installation of low energy light bulbs; installation of solar/wind auxiliary power for accommodation services; etc.
The short-term measure is aimed at meeting the target set in the IMO Initial GHG Strategy – to reduce carbon intensity of all ships by 40% by 2030, compared to 2008. These will be mandatory measures under MARPOL Annex VI. They will bring in
Attained Energy Efficiency Existing Ship Index (EEXI) is required to be calculated for ships of 400 gt and above, in accordance with the different values set for ship types and size categories. This indicates the energy efficiency of the ship compared to a baseline. Ships are required to meet a specific required Energy Efficiency Existing Ship Index (EEXI), which is based on a required reduction factor (expressed as a percentage relative to the EEDI baseline).
Annual operational carbon intensity indicator (CII) and CII rating.
The Carbon Intensity Index guidelines is briefly as follow:
Guideline G1 for operational Carbon Intensity Indicators and the calculation methods.
Guideline G2 on the reference lines for use with the Operationa Carbon Indicators.
Guideline G3 for the operational carbon intensity reduction factors relative to reference lines.
Guideline G4 on the operational Carbon Intensity rating of ships.
Marine Emission Technology – ME-Tech can perform and support you through all guidelines.
Different solutions is needed to obtain the goal of reducing the GHG from your vessels.
