Hybrid Conversion

Benefits:

  • Significant reduction of greenhouse gas emissions and diesel particulate matter
  • For stand-by or for low power operations, the Corvus Energy Storage System permits the vessel to be operated in noiseless, zero emissions mode
  • Maintenance savings leading to a rapid return on investment: Hybrid technology means minimized engine use and more time between engine overhauls and oil and filter changes
  • Engines run at or near best efficiency, and only when needed for cleaner combustion
  • Because hybrid technology shares the propulsion load between diesel and electrical sources, it means no unnecessary idling with main engines
