Marubeni to conduct fleet-wide emissions study ahead of EEXI and CII

Japanese general trading company Marubeni is to work with ClassNK and its NAPA software subsidiary on a project to examine potential fuel and emission savings through voyage optimisation and compare the impact of different strategies, ahead of the entry into force of EEXI and CII requirements in 2023.

NAPA will use its Fleet Intelligence platform to retrospectively analyse the impact of EEXI (Energy Efficiency eXisting ship Index) using actual vessel performance across Marubeni’s fleet and compare it against similar fleets, in terms of transportation capacity, CO2 emissions and fuel consumption. ClassNK will provide verification services to review the analysis and its accuracy.

The partners expect that this process should predict how well Marubeni vessels will be able to perform in the future with reduced propulsion power and allow the company to judge whether those ships can remain competitive in the market from 2023 onwards when the new requirements enter into force.

NAPA will also calculate Carbon Intensity Indicators (CII) for the vessels using historical operational data and predict how much performance could be improved using weather routing systems.

“It is a very exciting opportunity for Marubeni to collaborate with NAPA and ClassNK on this joint study that will help reduce CO2 emissions and fuel consumption,” said Takayuki Hase, General Manager, Ship Department at Marubeni.

“We hope that this joint study will make a contribution to improving the maritime industry’s carbon footprint through digital solutions for shipping operations.”
