Recently, three ultra-shallow water cutter suction dredgers designed and built by China Communications Group Hong Kong Zhenhua Engineering Co., Ltd. for projects in Sri Lanka and Indonesia—namely "Yuhua," "Jinhua," and "Yinhua"—were officially launched in Panyu, Guangzhou. These vessels are specifically engineered for shallow water environments, with a minimum operating depth of just 0.8 meters and a maximum of up to 9 meters. Their modular design allows them to be disassembled into containers, making it easy to transport them via water or land routes. This feature significantly enhances their mobility and reduces deployment costs.
Equipped with aluminum alloy cylinder diesel engines as their main power source, the dredgers also feature hydraulic control systems for both the winch and operational mechanisms. The design ensures a short production cycle, low manufacturing cost, and ease of assembly and maintenance. Additionally, the vessels are user-friendly, offering simple operation and efficient maintenance, which makes them ideal for use in remote or challenging locations. With these advantages, "Yuhua," "Jinhua," and "Yinhua" represent a significant advancement in modern dredging technology, especially for regions with limited access to deep-water infrastructure.
Custom Rapid Prototyping
Product modeling and design ability has been greatly improved, but after the completion of product design, before mass production, we must make samples to express the design idea, quickly obtain the feedback information of product design, and evaluate and demonstrate the feasibility of product design. In today's increasingly fierce market competition, time is benefit. In order to improve the competitiveness of the product market, the whole process from product development to mass production is urgently required to reduce the cost and improve the speed. The emergence of rapid prototyping technology provides an effective way to solve this problem, and has attracted much attention at home and abroad
