IACS launches EEXI implementation guidelines

IACS has released IACS Recommendation No 172, EEXI Implementation Guidelines, that have been developed to support the global and consistent implementation of the newly developed EEXI International Maritime Organization framework.

  • The publication will provide additional advice and guidance on certain elements of the regulatory text where cross-industry discussions had identified technical implementation nuances associated with the EEXI framework.
  • Specific issues identified as needing further elaboration in Rec.172 include:
  • the approval of the EEXI Technical File;
  • non-overridable power limitation;
  • EEXI calculation methodology for LNG Carriers;
  • ship type applicability;
  • appropriate Specific Fuel Consumption (SFC) values and;
  • the uniform performing and validating of numerical calculations of the EEXI reference speed (Vref).

With the amendments to MARPOL Annex VI incorporating mandatory EEXI becoming effective on November 1st 2022 and taking effect at the shipboard level on January 1st 2023, IACS said that it remained vitally important for IACS to provide and maintain clarity and to allow relevant stakeholders to benefit from a common approach amongst IACS members in the calculation of a ship’s EEXI.
