The long-term aim of the IMO Greenhouse Gas Strategy is to have carbon intensity of international shipping reduced by 40% by 2030, compared to 2008, and by 50% by 2050. In view of this, short-term measures are intended to take place and come into force as early as 2023.
Let’s meet these deadlines together.
The long-term aim of the IMO Greenhouse Gas Strategy is to have carbon intensity of international shipping reduced by 40% by 2030, compared to 2008, and by 50% by 2050. In view of this, short-term measures are intended to take place and come into force as early as 2023.
The IMO Marine Environment Protection Committee’s (MEPC) 75th session was held in November 2020. It approved amendments to MARPOL Annex VI, introducing an Energy Efficiency Design Index for existing ships (EEXI). Subject to adoption at MEPC 76 in June 2021, the requirements are expected to come into force in 2023. The EEXI will be applicable to all vessels above 400 GT, falling under MARPOL Annex VI. By then, the shipping companies should have proceeded with:
The first evaluation concerns the requirement for the EEXI decrease by the first Annual Survey after October 2022 (or 1st January 2023). In case the EPL required for being compliant with the EEXI decrease significantly affects the ship’s speed (in comparison with the present service speed), energy saving measures and devices will need to be evaluated.
There may be a second phase of the EEXI decrease in 2026. Evaluation of the results of the first phase of the EEXI will take place in 2026. As a result, the vessels which are compliant in the first stage using EPL, may not necessarily achieve it in the second stage.
Our qualified and experienced consultants can assist you in navigating through the current and upcoming regulations related to decarbonisation. Together we can find the optimum way to become compliant by applying the following methodology and steps:
Calculation of the EEXI of the vessel and the Engine Power Limit (EPL) required for the vessel to comply with the applicable reduction. These must follow the draft regulations of MEPC 75.7
Preliminary evaluation of the vessel's propulsion characteristics and find a margin for improvement (with the modification and/or replacement of the propeller, installation of a propeller cap and a hull duct, flow separation alleviating devices etc). A detailed evaluation shall be achieved with the use of CFD calculations, which can be separately offered upon request. The applicability and effectiveness of all available energy saving devices will be presented in a detailed report.
