EEXI

New efficiency standard for existing fleet

From January 2023, most commercial vessels will have to comply with the new Energy Efficiency Existing Ship Index (EEXI) standard. The EEXI introduces the same energy efficiency requirements for existing ships as those that were put in place for newbuildings by the EEDI in 2013. To comply with the standard, owners, classification societies and equipment suppliers must all take action now. Ship&Offshore spoke with Andy McKeran, Maritime Performance Services Director at Lloyd’s Register about the implementation of the EEXI. We also asked two propulsion experts, Christoph Rofka, senior vice president – head of Global Product Group Medium, Low-Speed and Rail at ABB Turbocharging and German Weisser, WinGD R&D Senior Advisor, Sustainability, about measures that could be taken to comply with the regulation.
