Maritime software services provider Napa has released preliminary results of research showing engine power limitations required by the Energy Efficiency Index for Existing Ships (EEXI) would only come into effect for bulkers at high-speed peaks.

Its retro-optimisation study used real voyage data from 1,500 vessels over 12 months in 2019 to explore the potential effect of EEXI on the transport capacity, emissions and carbon intensity of the global bulker fleet.

"The data shows that the engine power limitations required by vessels to comply with EEXI would only have come into effect at high-speed peaks," said the Finnish analyst.
