Energy Efficiency Existing Ship Index Compliance Guide

This guide provides detailed information regarding the implementation of the Energy Efficiency Existing Ship Index (EEXI) as mandated by amendments to MARPOL Annex VI, effective from 1 January 2023. It outlines the necessary actions vessel owners must take to ensure compliance, including the submission of the EEXI Technical File (EEXI TF) for technical review and preparation for surveys. The document specifies the calculation requirements for both attained and required EEXI, referencing relevant regulations and guidelines from the International Maritime Organization (IMO). It details the steps for maintaining compliance, including the need for re-approval if vessel modifications occur. The guide emphasizes the importance of preparing for onboard verification and provides timelines for compliance verification associated with the International Air Pollution Prevention (IAPP) Certificate. Additional guidance on the use of the overridable Shaft/Engine Power Limitation (SHaPoLi/EPL) system is also included, along with recommendations for updating maneuvering charts. Overall, the document serves as a comprehensive resource for understanding and implementing EEXI requirements.
