2. Lightweight and low-noise design, high adaptability to ships: using aviation grade aluminum alloy fuselage and modular integrated structure, the whole machine reduces weight by 25%, effectively reducing ship load and saving installation space; Professional acoustic optimization and tuning, with a working noise level of less than 75dB, optimized navigation and riding environment, suitable for retrofitting and carrying ships in inland and offshore waters.
3. Abundant power and energy saving, reducing shipping costs and increasing efficiency: 11.81L golden displacement, rated power of 321KW, continuous power up to 380kW, stable power output suitable for complex water conditions; Equipped with intelligent common rail fuel system and variable cross-section turbine technology, the fuel efficiency is improved by 15%, and the long-term reduction of ship fuel operating expenses is achieved.
4. Ultimate durability and reliability, suitable for long-term water operations: After 2000 hours of full condition bench testing, the core component B10 has a service life of up to 30000 hours, is corrosion-resistant and anti bumpy, suitable for complex water conditions such as high humidity, high salt spray, and inland rivers, with an extremely low failure rate.
5. Intelligent operation and maintenance are worry free, and after-sales response is efficient: equipped with a dedicated remote intelligent diagnostic system, the engine operation data is monitored 24/7, achieving 4-hour high-speed fault diagnosis and response, reducing the length of ship downtime for maintenance, and ensuring uninterrupted navigation of ships in inland waterways and offshore areas.
1. Southeast Asian offshore shipping owners: “The salt spray corrosion in the Southeast Asian offshore waters is strong, and the durability requirements for marine engines are extremely high. CAMC Hanma marine engines have a lighter weight, lower sailing noise, continuous and stable power, and save a lot of fuel consumption compared to old models. Remote fault diagnosis is very convenient, and the downtime for maintenance is greatly reduced, which is suitable for our normal operation of offshore freight transportation. ”
2. Cross border inland waterway transportation operator: “We are equipped with this engine in bulk for cross-border inland waterway transportation. The whole machine is well crafted, easy to install, and runs smoothly for long-term water navigation. Its durability far exceeds that of imported models in the same price range. The brand has strong intelligent manufacturing capabilities, timely supply of overseas spare parts, energy-saving and fuel-efficient, and low-cost operation and maintenance, making it a cost-effective choice for marine power. ”
CAMC International Trade Co., Ltd. is located in Ma'anshan Economic and Technological Development Zone, Anhui Province.
