Industry & Safety Standards
The Challenge in Port Operations
Port terminals rely on heavy, diesel-powered equipment (RTGs, RMGs, large forklifts) that generates high operating costs and substantial emissions. Transitioning to cleaner, more efficient power sources is critical for both financial resilience and environmental responsibility in line with global shipping trends.
Operational Costs
Fuel accounts for a disproportionate share of operating expenses as port equipment runs continuously under high, variable loads.
Local Air Quality
Dense concentrations of diesel emissions (PM, NOx) from yard equipment directly impact local air quality and human health near port cities.
Maintenance Complexity
Frequent maintenance cycles due to carbon buildup in diesel engines reduce operational uptime and increase service costs.
Our Dual Fuel Retrofit
Converting Existing Port Machinery to LNG/CNG
Our proprietary Dual Fuel system seamlessly integrates with your existing diesel engines (on RTGs, RMGs, Terminal Tractors, etc.). This allows the engine to run primarily on cleaner, cheaper Natural Gas (LNG or CNG) while using a small pilot quantity of diesel for ignition.
Key Technological Advantages:
- Intelligent Substitution: The system automatically and dynamically optimizes the gas-diesel ratio (up to 70% gas substitution) based on real-time engine load to maximize efficiency and safety.
- Non-Invasive Installation: The conversion is external to the engine block, preserving the original diesel engine warranty and core integrity.
- High Reliability: Maintains 100% torque and power output required for continuous, heavy-duty port lifting operations.
