Dual-Fuel Engine Retrofit (DF Engine)
A dual-fuel engine retrofit is a technology that converts existing single-fuel engines into dual-fuel engines capable of using two fuels. This enables a response to green fuel regulations adopted at the IMO and MEPC 83 meetings and allows the use of next-generation green fuels such as LNG, methanol, ammonia, and even hydrogen.
- 1. Harmful Substance Emission Reduction
  Significantly reduce harmful substance emissions—such as SOx, NOx, and CO₂—from exhaust gases, thereby improving environmental regulatory compliance.
- 2. Operational Flexibility
  When a green alternative fuel supply is difficult, conversion/operation with existing fuel is possible, providing high operational flexibility.
Engine Part-Load Optimization (EPLO)
Engine Part-Load Optimization (EPLO) is a technology that retrofits engines and turbochargers to optimize for actual operating speeds. This enables reduced fuel consumption, improved environmental performance, and enhanced overall vessel operational efficiency.
- 1. Fuel Reduction and Environmental Performance Improvement
  Expect up to 6g/kWh in fuel efficiency improvements, along with reduced carbon emissions. Suppress carbonization deposits to extend engine life and reduce maintenance costs.
- 2. Operational Efficiency Enhancement
  Enable high combustion efficiency and operational efficiency improvements through turbocharger retrofitting optimized for actual vessel operating speeds.
Alternative Maritime Power (AMP)
Alternative Maritime Power (AMP) is a technology that meets a vessel's electrical demand by supplying power from shore while the vessel's engine is stopped during berthing. This enables improvements in air quality near ports and an effective response to environmental regulations.
- 1. Zero Emissions and Air Quality Improvement
  By stopping engine operation during berthing and using shore power, emissions of SOx, NOx, CO₂, and particulate matter are eliminated, reducing air and noise pollution near ports.
- 2. Enhanced Environmental Regulation Response
  With AMP installation and use becoming mandatory at major ports, including IMO, North America, Europe, and China, this enables an effective response to international and regional environmental regulations.
Propeller Re-design
Propeller redesign is a technology that maximizes propulsion efficiency and operational performance by optimizing propeller shape, size, blade count, pitch, material, and other parameters based on actual vessel operating conditions.
- 1. Propulsion Efficiency and Fuel Reduction
  Reduce energy loss and improve fuel efficiency through a design optimized for operating conditions, reducing operational costs.
- 2. Noise and Vibration Reduction
  Reduce cavitation by improving flow conditions and minimizing noise and vibration impacts on vessel structures and crew.
Bulbous Bow Optimization
Bulbous bow optimization is a technology that enhances operational efficiency by minimizing wave-making resistance through redesigning the bulbous bow to match actual vessel operating conditions.
- 1. Drag Reduction and Propulsion Efficiency Enhancement
  Reduce overall drag by decreasing wave resistance and secure more thrust with the same engine output, increasing propulsion efficiency.
- 2. Fuel Reduction Effect
  Energy required for propulsion decreases due to drag reduction, reducing fuel consumption.
Air Lubrication System (ALS)
An Air Lubrication System (ALS) is a technology that reduces frictional resistance by injecting air at the vessel's bottom to form an air layer between the hull and seawater.
- 1. Fuel Reduction and Greenhouse Gas Reduction
  Reducing friction resistance decreases fuel consumption and emissions of CO₂, NOx, and SOx, making it effective for environmental regulatory response.
- 2. Operating Cost Reduction
  Enable a total reduction in vessel operating costs through fuel savings.
Wind Assisted Propulsion System (WAPS)
Wind Assisted Propulsion System (WAPS) is a system that assists vessel propulsion using wind power, reducing fuel consumption and carbon emissions.
- 1. Fuel Reduction and Greenhouse Gas Reduction
  Utilize wind power as auxiliary power to reduce engine load and simultaneously decrease fuel consumption and greenhouse gas emissions.
- 2. Operating Cost Reduction
  Enable a total reduction in vessel operating costs through fuel savings.
- 3. Operational Efficiency Enhancement Through Incentive Acquisition
  Acquire incentives in accordance with Fuel EU Maritime regulations to enhance vessel operational efficiency.
Exhaust Gas Boiler
An Exhaust Gas Boiler is a technology that heats water using high-temperature exhaust gases generated from vessel engines. Recycling exhaust gases reduces fuel consumption compared to conventional boilers and maximizes vessel energy efficiency.
- 1. Fuel Reduction and Operating Cost Reduction
  Reduce fuel consumption by utilizing exhaust gas heat instead of conventional boilers, thereby reducing operating costs.
Propeller Hub Cap (Hi-Fin)
A propeller hub cap (Hi-Fin) is a technology that enhances vessel propulsion efficiency by attaching small fin devices to the propeller center (hub/boss cap) to control vortices generated behind the propeller.
- 1. Propulsion Efficiency Enhancement and Low-Speed Operation Optimization
  Improve propulsion efficiency by reducing vortices, enabling reduced fuel consumption. Demonstrates greater efficiency improvements, especially at low speeds.
Pre-Swirl Duct (Hi-PSD)
A pre-swirl duct (Hi-PSD) is a structure installed in front of the propeller that controls fluid flow from the hull to induce rotational motion in advance. It is equipment that enhances propeller efficiency and reduces fuel consumption by optimizing the velocity distribution of water reaching the propeller.
- 1. Propulsion Efficiency and Fuel Reduction
  Improve propulsion efficiency by controlling fluid flow in advance and reducing fuel consumption to lower operational costs.
- 2. Resistance Reduction and Vibration Mitigation
  Mitigate flow interference between hull and propeller and reduce vibration and noise by equalizing velocity distribution.
Variable Frequency Drive (VFD)
A Variable Frequency Drive (VFD) is a technology that controls the speed and torque of AC motors by adjusting the frequency of the power supply (Hz).
- 1. Fuel Reduction and Operating Cost Reduction
  Reduce fuel costs and operating costs by decreasing energy consumption through enhanced motor operation efficiency.
- 2. Equipment Protection and Precise Control
  Prevent equipment overload and damage by precisely controlling motor speed and torque, and improve system performance and reliability.
