1.Project Background: Equipment Demand in the Southeast Asia Sand Mining Boom
1.1 Current Status of Sand Resources in Cambodia
The Mekong River Basin in Cambodia contains over 5 billion tons of high-quality river sand resources, with mud content below 3% and silica content reaching 92%, making it particularly suitable for high-end concrete production. With the advancement of large-scale infrastructure projects such as the Phnom Penh-Sihanoukville Expressway, local sand prices have surged by 260% over three years, driving a sharp increase in demand for mechanized sand dredging equipment.
1.2 Market Opportunities
Over 80% of domestic sand mining enterprises in China have now turned their attention to the Southeast Asian market. Cambodia has become a global hotspot for sand dredging equipment due to its abundant sand resources in the Mekong River Basin (proven reserves exceeding 5 billion tons), lenient foreign investment policies (allowing 100% foreign ownership), and rapidly growing infrastructure demands (construction industry growth rate reached 9.2% in 2023). Tai’an Ocean Pump, leveraging 18 years of professional expertise, customized a 200 cubic meters suction-type sand dredger for a client from Xinyang, Henan Province. This vessel has operated continuously for 2,000 hours in Cambodia’s Tonlé Sap Lake, setting an industry record with a daily output of 5,800 cubic meters.
2.Detailed Technical Parameters of the Equipment
2.1 Hull Structural Design Specifications
The vessel features a 12m×3.8m×1.26m hull with a golden aspect ratio of 3.16:1, optimizing stability and maneuverability. Critical components include:
Bottom Plate: 6mm Q345 manganese steel, enhancing impact resistance by 40%
Side Plates: 5mm anti-corrosion steel, passing 2,000-hour salt spray tests without rust formation
Deck: 4mm diamond-pattern anti-slip plate with a friction coefficient of μ≥0.85
This structural configuration ensures durability in Cambodia’s demanding river environments while maintaining operational safety and efficiency.

5.summary
During use, the dredger also demonstrated its durability and reliability. After many long-term operations, the performance of the dredger has not declined significantly, and it still maintains excellent dredging effects. This is due to Taian Ocean Pump’s high requirements for product quality, strict production standards, and excellence in every detail.
In addition, Taian Ocean Pump also provides a full range of after-sales services to ensure that the dredger is always in the best condition when operating on site in Africa. Whether it is technical support, spare parts supply or emergency repairs, Taian Ocean Pump’s professional team can respond in time and provide efficient solutions.
In short, Taian Ocean Pump’s dredging equipment has demonstrated excellent performance and reliability at the Cambodian sand pumping site, making an important contribution to the dredging of local waterways. I believe that in the future, Taian Ocean Pump’s products will continue to provide high-quality solutions for global customers.
