NAPA, ClassNK and Marubeni to study on EEXI and CII’s effect on operations

NAPA, the leading maritime software, services, and data analysis provider, will work with leading class society ClassNK and Japanese general trading company Marubeni to assess what fuel and carbon emission savings could be achieved through voyage optimization.

NAPA will use its Fleet Intelligence platform to retrospectively analyze the impact of EEXI (Energy Efficiency Existing Ship Index) using the actual vessel performance 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 new EEXI and CII (Carbon Intensity Indicator) requirements enter into force.

The cloud-based NAPA Fleet Intelligence platform combines NAPA’s expertise in naval architecture with many years of data on actual sailed voyages and weather conditions, using NAPA’s unique performance model to generate insights. With no need for commissioning or hardware installation onboard vessels, the platform can easily analyze past performance and optimize fleet operations.

This will enable NAPA, ClassNK and Marubeni to analyze the effect of EEXI requirements on Marubeni’s fleet in terms of transportation capacity, CO2 emissions and fuel consumption. NAPA will also calculate CII for vessels using historical operation data and predict how much performance can be improved with the state-of-the-art weather routing system, NAPA Voyage Optimization.
