Energy Management System

Ingeship Energy Management System

EMS (Energy Management System) is a key element of the vessel, providing the best control platform for the hybrid technology. The integration between the Frequency Converters and Batteries is done in order to achieve the following main goals:

1. Reduce fuel consumption.
2. Lower greenhouse emissions and noise levels.
3. Reduce engines maintenance cost.
4. Obtain higher energy efficiency.
5. Increase operation reliability and safety.

Ingeship-EMS´ software controls and monitors the vessel’s power supply. At the same time it manages the energy supply from the different available power sources in real time (main diesel and CNG Engines, batteries and solar panels).

The EMS provides different operation modes:

1. Peak shaving
   • Generator power level steadiness.
   • Generator power variations are allowed and ramp-controlled in order to achieve dynamic peak shaving that optimizes the usage of batteries.
2. Power boost
3. Spinning reserve. In the event of a main engine/generator loss:
   • Propulsion is not affected as the main propellers remain supplied by batteries.
   • Blackout is avoided. High speed frequency sensing in the frequency converters along with AFE’s power flow inversion capability allows to supply Energy to MSB from the batteries.
4. Shore connection capability for battery charging:
   • Battery charge mode while loading between transits
   • Night charge mode for battery charge while docked
5. Big sizing of the ESS. According to the optimization strategy of EMS
6. Other operation modes:
   • Vessel operation fully electric mode by batteries
   • Vessel operation on diesel
   • Vessel operation on CNG
