Korean Register (KR) has conducted a preliminary analysis to ascertain the industry’s readiness for the IMO’s new Energy Efficiency Existing Ship Index (EEXI) and the Carbon Intensity Indicator (CII) regulations, and has released a comprehensive presentation on Youtube to help shipowners prepare and manage compliance.

MEPC 76 adopted amendments to MARPOL Annex VI to implement the EEXI as a technical approach and the CII as an operational approach to achieve the short-term measures to cut carbon emissions from ships. The new measures will be applied to existing ships from 2023, creating a significant challenge for the maritime industry.

The key decisions from the session regarding the EEXI/CII guidelines are:

  • Where an engine power limitation (EPL) is installed, the engine power in the EEXI calculation (PME) should be 83% of the maximum limited power (MCRlim) or 75% of maximum power (MCR), whichever is lower,
  • the CII reduction rate will be applied equally to all ships regardless of ship type, and the method of applying the reduction rate in stages was adopted,
  • numerical analysis has been accepted as a substitute for the model test, and
  • the SEEMP guidelines were not finalised but have been sent to a Correspondence Group for further work.
  • KR has conducted a preliminary analysis to estimate the impact of the new regulations on the industry. The results show that most ships do not meet the EEXI regulations and the ships that do meet the regulations, are small in size.

If the EEXI regulations are not satisfied, the shipping company must implement other measures such as installing a shaft/engine power limitation (SHAPoli/EPL) system or Energy Saving Device (ESD) to improve the vessels energy efficiency. When the shaft/engine output limiting system is applied without ESD or retrofitted, the shipping company should expect a reduction of ship speed from 0.9 knots to 6.5 knots (tanker average 1.7 knots, bulk average 2.4 knots, container average 4.1 knots) which is a rapid deceleration.

KR is providing customised technical services to allow its customers to adopt the most beneficial countermeasures for their individual vessels, such as determining exactly how much engine power limitation and reduction in ship speed is required. KR has also launched web-based smart software to provide EEXI calculations and CII, offering an easy and simple way to check whether a vessel meets the EEXI requirements or not.

KR has published a presentation on its Youtube channel, offering comprehensive guidance on EEXI/CII compliance, with details of its preliminary analysis and introducing energy saving devices which will help shipping companies to make the necessary changes to manage their decarbonisation progress. KR is also developing manuals and will be offering training seminars to support this important and rapid industry transition.
