How Much Fuel and Carbon Can Voyage Optimization Save?

With IMO’s EEXI and CII requirements putting the pressure on shipowners to reduce carbon emissions, Finnish-based software specialist NAPA and ClassNK are working with Japanese trading house Marubeni on a major fleet-wide study.

The aim is to evaluate potential fuel savings achievable through voyage optimization, and compare adaptation strategies

NAPA will use its Fleet Intelligence platform to retrospectively analyze the impact of EEXI (Energy Efficiency Existing Ship Index) using actual vessel performance data across Marubeni’s fleet and compare it against similar fleets. ClassNK will provide its expertise in verification, analysis and accuracy. Based on this, NAPA will predict how well the Marubeni vessels will be able to perform in the future with reduced propulsion power and remain competitive in the market from 2023 onwards when the new EEXI and CII (Carbon Intensity Indicator) requirements enter into force.
