Eco Friendly Navigation Technology

Simultaneously reducing both the fuel consumption and NOx emissions of marine diesel engines is difficult due to the trade-off relationship between these objectives. KHI has succeeded in optimizing the fuel consumption and NOx emissions of marine diesel engines by implementing a smart electronic system for controlling the movement of the fuel injection and exhaust valves based on the operating load.

Optimizing the hull form and improving the propulsion efficiency can reduce the amount of fuel consumed by ship operations, thereby mitigating the ship's environmental impact. KHI develops hull forms with reduced resistance and increased propulsion efficiency by using computational fluid dynamics (CFD) simulation technology and conducting tank tests using large-scale models to improve accuracy.

Optimization of the hull form

Designing the stern propeller so that it will produce a propulsive force requires sophisticated technological capabilities because the propeller operates behind the hull, where the flow is extremely complex. KHI analyzes the inflow at the propeller to optimize the propeller shape.
