From January 2023, the revised MARPOL Annex
VI will enter into force and all existing ships of 400 GT and above must comply
with IMO’s Energy Efficiency Existing Ship
Index (EEXI), requirements relating to CO2 emissions per cargo ton and mile.
Datum Electronics has developed a shaft
power limitation (ShaPoLi), EEXI Shaft Power Acquisition Module, that when
integrated with Datums Shaft Power Meter, provides a verified shaft power data
signal to the propulsion control system to limit the engine power.
Voyage reports are automatically produced
in support of the regulatory port authority documentation requirements,
providing the most convenient way to evidence EEXI compliance.
In exceptional circumstances where the
Ships Master or OICNW need to override the EEXI power limiter (for events such
as Adverse Weather, Ice-Infected Waters, Rescue Operations, Avoidance of
Pirates
and Engine Maintenance), Datums EEXI Shaft Power Acquisition Module logs the exact time and reason for the power exceedance.
Datums EEXI Shaft Power Acquisition Module
continuously monitors, records and displays the instantaneous power being
developed at the propulsion shaft.
