On June 11, 2026, Vice President Xie of Guangdong Zhongxing Hydraulic Transmission Co., Ltd. led a delegation comprising core technical and market‑R&D personnel to China Shipbuilding Group South China Marine Machinery Co., Ltd. for a specialized technical exchange symposium on marine‑power hydraulic transmission. Senior technical experts and R&D leaders from both sides convened in the Party‑Building Conference Room to discuss topics related to ship main‑engine integration, offshore engineering equipment, and ship auxiliary‑system applications. Marine hydraulic coupling A comprehensive and in-depth dialogue was held on application scenarios, challenges in adapting to operating conditions, and domestic substitution strategies, jointly identifying priorities for upgrading marine propulsion systems and building a platform for technological collaboration to support the green and efficient development of the shipbuilding industry.
China Shipbuilding Group South China Marine Machinery Co., Ltd., a core ship‑support enterprise under CSSC, has been deeply engaged in the R&D and manufacturing of marine power equipment for many years. It boasts a mature industrial system in areas such as marine diesel engine support, offshore engineering machinery, and complete sets of marine auxiliary equipment, serving as a key pillar of the shipbuilding industry chain in South China. The company adheres to stringent industry standards regarding the reliability, corrosion resistance, heavy‑load stability, and energy‑saving performance of marine transmission systems. This technical exchange represents a pivotal event for ZTE Hydraulic Transmission as it deepens its presence in the marine sector and aligns with the needs of leading shipbuilders. It also serves as a professional showcase of the domestic hydraulic transmission equipment’s capabilities in high‑end marine applications.
 
At the exchange symposium, our technical team comprehensively presented the full product portfolio of Guangdong Zhongxing’s marine hydraulic couplings to the participating technical experts from CSSC South China Ship Machinery, employing a variety of formats—including high-definition projection demonstrations, physical product‑manual displays, and operational‑condition simulation animations. The demonstration vividly recreated extreme operating conditions such as the high‑temperature, high‑humidity environment of a ship’s engine room, seawater salt‑spray corrosion, significant start‑stop impact loads, and prolonged continuous operation. It also provided a clear, visual comparison of the performance differences between conventional rigid transmissions and Zhongxing’s flexible hydraulic coupling technology, with a focused breakdown of the product’s core technological advantages in marine applications.

During the panel discussion, both sides engaged in an in-depth exchange on the pain points facing the shipbuilding industry. Shipboard equipment has long been confronted with common challenges such as frequent start‑stop shocks, difficulties in handling heavy‑load startups, significant vibration and noise in transmission systems, easy damage to main engines under overload conditions, and corrosion of components caused by marine salt spray. In response to these issues, the ZTE technical team, drawing on more than a decade of experience in hydraulic transmission R&D, systematically presented customized solutions for marine‑specific fluid couplings:

 

First, the advantage of flexible cushioning and protection: ZTE’s marine torque-limiting fluid couplings utilize a liquid‑based flexible transmission to significantly reduce impact loads during the startup of shipboard auxiliary machinery, pump units, and winches, while isolating vibration transmission. This effectively extends the service life of critical equipment such as the main engine, gearbox, and pump bodies, thereby lowering ship‑operational and maintenance costs.

 

Second, customized environmental‑weather‑resistant design for marine applications. To withstand the high‑salt‑mist and high‑humidity conditions at sea, the entire ZTE marine coupling unit is equipped with class‑approved anti‑corrosion coatings, stainless‑steel sealing components, and an integrated waterproof and dustproof enclosure, ensuring long‑term stable performance on inland vessels, nearshore operation vessels, and offshore engineering platform equipment.

 

Third, it provides dual safeguards for energy efficiency and overload protection. The product features an integrated intelligent torque‑limiting protection mechanism that automatically disengages under conditions of equipment jamming or overload, effectively preventing engine damage. At the same time, its internal flow‑path hydraulic design has been optimized to deliver transmission efficiency exceeding industry standards, reducing both fuel and electrical consumption over long‑term operation and aligning with policies promoting green, low‑carbon shipping.

 

Fourth, it offers full‑scene customized adaptation capabilities. Based on the power and speed requirements of various shipboard equipment—such as pumps, fans, winches, conveyors, and diesel generator sets—it provides non‑standard, custom‑designed dimensions and mounting interface solutions, seamlessly integrating with existing vessel retrofit projects and new‑build installations to enable rapid domestic substitution for imported drive systems.

Technical experts from CSSC South China Marine Machinery attended the meeting, meticulously taking notes and photographing technical documentation throughout. They raised numerous specialized questions regarding real-world operating conditions, such as heavy‑load scenarios on ocean-going vessels, confined installation spaces within ship holds, and prolonged, uninterrupted voyages. Vice President Xie and our R&D engineers provided detailed, item‑by‑item responses, drawing on a wealth of practical project implementation cases to share application experience. The two sides exchanged views on potential areas of collaboration, including new‑build vessel equipment, retrofitting transmission systems on aging ships, and supplying components for offshore engineering equipment, reaching several technical agreements. The attending experts highly commended Zhongxing Hydraulic Transmission’s focused, in‑depth approach to niche markets and its R&D strategy aligned with the actual needs of the maritime industry, concluding that domestically produced marine hydraulic couplings now possess the technical capability to replace comparable foreign products. They look forward to advancing into trial‑run testing and pilot projects, paving the way for deeper cooperation.
 
Guangdong Zhongxing Hydraulic Transmission Co., Ltd., a leading domestic manufacturer of hydraulic couplings, has for many years been strategically expanding into multiple transmission markets, including marine, port, mining, metallurgical, and power‑generation sectors. In the marine industry, the company has established an independent R&D team dedicated to ship‑specific applications, continuously refining its products to meet international standards for marine propulsion equipment. Unlike general‑purpose industrial couplings, all of the company’s marine‑grade products undergo rigorous specialized testing—such as salt‑spray aging, continuous heavy‑load durability, and high–low temperature cycling—and are backed by comprehensive proprietary intellectual property rights, enabling the company to overcome overseas technology barriers. As a result, it can provide a one‑stop hydraulic transmission solution for major domestic shipbuilders and marine‑engine component suppliers.
 
During the exchange, Vice President Xie stated that the shipbuilding industry is a core pillar of high-end equipment manufacturing, and marine equipment places exceptionally stringent demands on the reliability of transmission systems. ZTE has consistently positioned itself as a “domestically‑produced provider of high‑end transmission equipment,” and continues to ramp up R&D investment in ship‑specific couplings. This technical dialogue with CSSC South China Marine Machinery has enabled the company to gain a precise understanding of the cutting‑edge technological needs of leading shipbuilders. Moving forward, the company will leverage the operational‑condition requirements gathered during this seminar to further refine its marine product portfolio and develop a next‑generation hydraulic coupling better suited to the extreme operating environments of ships, thereby contributing to the independent and controllable development of China’s domestic shipbuilding industry chain with stable, reliable domestically‑made transmission solutions.
 
This technical exchange event has established a high‑quality platform for technology sharing and resource collaboration between upstream and downstream enterprises. Moving forward, Guangdong Zhongxing Hydraulic Transmission will continue to deepen its technological integration with ship machinery and shipyard units under China Shipbuilding Group. Leveraging its proprietary expertise in marine hydraulic couplers, the company will further cultivate niche segments of the marine equipment supply chain, delivering domestically produced hydraulic transmission products that are high‑performance, highly durable, and energy‑efficient. In doing so, it will support the high‑quality development of the shipbuilding and marine equipment industries across South China and throughout the country, helping China’s marine equipment manufacturing sector ascend to a new stage of self‑reliance and strength.
