EEXI SHAFT POWER SYSTEM (SHaPoLi)
The Shaft power limitation (SHaPoLi) EEXI Shaft Power System, provides the necessary features and functionality to comply with the MARPOL Annex VI, MEPC.335(76) EEXI regulations.
The system uses a Shaft Power Acquisition Module to constantly display, monitor and record propulsion shaft power to ensure compliance with the EEDI requirements relating to CO2 emissions for ships over 400 gross tonnage.
EEXI Shaft Power System (SHaPoLi)
- Datums EEXI Shaft Power Acquisition Module continuously monitors, records and displays the instantaneous power being developed at the propulsion shaft when the vessels engine shaft is connected to Datums Shaft Power Meter.
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 Ship’s Master or Office in Charge need to override the EEXI power limiter (for events such as Adverse Weather, Ice-Infected Waters, Rescue Operations, Avoidance of Pirates and Engine Maintenance), Datum’s EEXI Shaft Power Acquisition Module logs the exact time and reason for the power exceedance.
- The EEXI SHaPoLi Interface module incorporates highly encrypted software to support the regulatory needs for authenticated data. A point-to-point secure serial data link from the EEXI SPM Control unit to the bridge located EEXI Interface, provides uninterrupted data string, containing high accuracy torque, shaft rpm and power.
- The EEXI SHaPoLi Interface module is a high-performance industrial panel mounted computer, allowing for the secure storage of the critical logfile datasets.
- The EEXI SHaPoLi Interface module provides the ships Master or OICNW with the live and instantaneous Shaft Power being produced by the vessel, and represented relative to the Power Reserve threshold, as determined by vessel type and size.
