Shaft power limitation system to assist in EEXI compliance

Chris-Marine of Sweden has introduced a new hardware and software-based system to assist vessel operators in monitoring shaft power, to optimise their ship CII (Carbon Intensity Indicator) ratings and ensure compliance with new EEXI (Energy Efficiency eXisting ship Index) requirements.

From January 2023, the revised MARPOL Annex VI will enter into force and all existing ships of 400 GT and above must comply with EEXI requirements relating to CO2 emissions per cargo ton and mile.

Chris-Marine’s ShaPoLi system aims to support this process by enabling ship owners to limit the maximum shaft power output of their vessels without having to modify any of their existing machinery, to have greater control over their emissions.

The software will allow for real-time logging of power and speed data, with a built-in override function available that is accessible through the command panel installed on the bridge, in case of emergencies.

“Chris-Marine has been on the frontline of the energy efficiency field for quite some time now and so far, supported our customers with close to 2,000 Shaft power Monitoring Systems already installed on board ships worldwide,” said Björn-Thorben Porep, Technical Sales Team Leader at Chris-Marine.

“We are currently engaged in serious discussions with the classification societies to get approval of our technology, a technology that will help our customers not only to comply with EEXI, but to monitor and optimise their ship CII ratings in the future.”
