Electric Propulsion System
Fully Electric Systems
Fully electric propulsion systems utilize lithium-ion batteries to power electric motors, directly driving the propellers without the need for a gearbox. This configuration offers several benefits:
-
Environmental Sustainability: Operating without internal combustion engines, these systems produce zero emissions, significantly reducing the vessel's environmental footprint.
-
Operational Efficiency: Electric motors provide instant torque, enhancing maneuverability and responsiveness. The absence of a gearbox simplifies the drivetrain, reducing maintenance requirements.
-
Noise Reduction: The quiet operation of electric motors enhances onboard comfort and minimizes noise pollution, which is particularly beneficial in ecologically sensitive areas.
Hybrid Systems
Hybrid propulsion systems combine diesel generators with electric motors and lithium-ion batteries, offering flexibility in power management. This setup allows vessels to operate in different modes:
-
High-Speed Operation: Diesel generators can directly power electric motors for higher speeds, providing the necessary thrust for swift travel.
-
Economical Cruising: For slower speeds and daily operations, the vessel can rely on battery power, reducing fuel consumption and emissions.
Inline Hybrid Systems
Inline hybrid systems integrate a diesel engine with an electric motor connected in series with the gearbox and propeller shaft. This configuration offers several operational modes:
-
Diesel-Only Mode: The diesel engine drives the propeller directly, suitable for high-speed operations.
-
Electric-Only Mode: The electric motor propels the vessel, ideal for low-speed maneuvering or operations in emission-restricted areas.
-
Combined Mode: Both the diesel engine and electric motor work together, providing additional power when needed.
