The Full Electric system

The full electric propulsion system refers to an electric vessel powered primarily by batteries. It includes at least two independent battery sets, each capable of supporting the ship's entire voyage endurance.
✓

The ship's navigation and electronics, control system and hotel daily load will be all supplied by battery power.

📊

The battery powers air conditioning, cooling, refrigeration, ventilation, water pumps for supply and drainage, and all essential kitchen appliances.

Performance Metrics

Compare the performance of electric systems with traditional propulsion methods.

Energy Efficiency

Electric
Diesel
Electric: 95%
Diesel: 35%

Superior Energy Efficiency

Electric systems convert up to 95% of energy to motion, while diesel engines typically achieve only 35% efficiency, with the rest lost as heat and noise.

Lower Energy Costs Reduced Waste Heat Better Range

Maintenance Cost

Electric: Low
Diesel: High

Reduced Maintenance Costs

Electric propulsion systems have fewer moving parts, require no oil changes, and have significantly less downtime compared to conventional diesel engines.

Fewer Parts No Oil Changes Less Downtime

Noise Level (dB)

Electric: 45 dB
Diesel: 85 dB

Whisper-Quiet Operation

Electric systems operate at just 45 dB, comparable to a quiet conversation, while diesel engines generate up to 85 dB, which requires hearing protection for prolonged exposure.

Diesel
Electric: 40% Cost
Diesel: 100% Cost

Lower Operational Costs

Electric propulsion systems typically operate at 40% of the energy cost of diesel systems. While the initial investment is higher, the long-term savings on fuel costs provide significant economic benefits over the vessel's lifetime.

Reduced Fuel Costs Lower Price Volatility Better ROI Over Time

Cruising Range Comparison

Electric
Diesel
Electric: 15%
Diesel: 100%

Limited Cruising Range

Full electric vessels currently achieve approximately 15% of the endurance of conventional diesel vessels on a single charge. This makes electric propulsion ideal for short routes with regular charging opportunities.

Suitable for Short Routes Charging Infrastructure Required Improving with Battery Technology

Emissions Comparison

Electric: 0 CO₂/NOₓ
Diesel: High Emissions

Zero Local Emissions

Electric vessels produce zero local emissions during operation. In contrast, diesel engines release significant amounts of CO₂, NOₓ, SOₓ, and particulate matter that contribute to air pollution and climate change.

System Configuration

This Single Line Diagram illustrates our dual redundant marine electric propulsion system. Two 360kWh battery banks power twin 165kW electric motors through a sophisticated power management network. The system features 500kWe shore charging stations operating at 800VDC, multiple DCDC converters maintaining 750VDC on the main bus, and comprehensive protection through strategically placed fuses. DCAC inverters convert power for the vessel's 3-400V/230V AC systems. This symmetrical architecture ensures reliability—if one side fails, the other maintains operation. The design prioritizes redundancy, safety, and efficient power distribution for optimal marine performance in all conditions.
