The company's efforts to innovate independent innovation of high -end equipment of marine environmental protection, leading high quality with high standards, and rapidly "out of the circle" in the shipbuilding industry, becoming one of the important source of innovation in the ship's supporting equipment industry.

Aiming at cutting -edge technology

Aiming at the development direction of "resource conservation and environmental protection", Qingdao Shuangrui has continuously carried out innovation in high -end equipment and key systems of marine, and created a sustainable technology research and development system.

The ship's pressure water treatment system is a breakthrough point for Qingdao Shuangrui Innovation. Pressure water is the water and suspension of water and its suspension on the ship to control the vertical, leaning, water eating, stability, or stress on the ship. By adjusting the water capacity on the ship in real time, the ship can ensure the safe navigation of the ship. With the continuous growth of the international transport industry, the problem of foreign marine creatures brought about by pressure -loaded water discharge has attracted widespread attention. "In order to avoid the harm to the ocean, companies in the world's marine engineering equipment field have started to develop pressure -loading water treatment technology." Fu Hongtian, general manager of Qingdao Shuangrui, said that the company seized opportunities, quickly established a technical team, carried out technology to carry out technology Cover.

R & D is not smooth sailing. What parameters do the concentration of electrolytic activity can meet the emission requirements prescribed by international maritime organizations? The space on the boat is small. How to integrate the system to save space? Faced with a series of problems, Qingdao Shuangrui step by step.

After more than 4 years of research, the company has mastered key technologies such as neutralization technology, automatic monitoring system, safety hydrogen removal technology and volume requirements, and designed and manufactured prototypes and tested multiple times. The final approval. After that, the pressure -loading water management system was recognized by the China Class Class (CCS) type, marking the self -developed ships that develop and produce and produce and produce, and have completely independent intellectual property rights.

"We have declared 7 national invention patents and 1 utility model patent." Fu Hongtian said that the pressure -loading water management system broke foreign monopoly and allowed "Made in China" to win the right to speak in the field of global ship environmental protection equipment.

Qingdao Shuangrui improved the three -generation R & D system of "Promoting the first generation, developing generation, and planning the first generation", and continued to promote technological optimization and upgrading in the field of pressure -loading water treatment systems, making products more in line with the development trend and requirements of smart ships and green ships. At present, Qingdao Shuangrui has delivered more than 2,100 ships to the water -loading water system order, which is a leading position in the mid -large ship pressure -loading water treatment market.

In addition to the ship's pressure water management system, Qingdao Shuangrui also launched products such as ship exhaust gas desulfurization system, ship exhaust denitration system, and EGR wastewater treatment system. It has established a diversified ship supporting product system and has become a standard leader in the field of marine environmental protection.

Persist hard to practice internal skills

In order to continue to maintain the amount of technology and equipment, Qingdao Shuangrui optimized production layout, practiced internal skills, and actively responded to risks and challenges in the international market.

In the Qingdao Shuangrui production workshop, a robot waving a "arm" was busy making components of ship equipment, and the flashing electronic screens in various areas showed the progress of various processes. In order to regulate the production site, Qingdao Shuangrui finely produced the production process to the station and process level, relying on the production and manufacturing execution system, realized the electronic and synchronous transmission of technical data, and promoted the standardization and visual management of production site.

"In the manufacturing process, we have established a lean production model." Dong Ruyi, deputy general manager of Qingdao Shuangrui, told reporters that the company has established a digital manufacturing platform with the production and manufacturing implementation system as the core to achieve the transparency of the manufacturing process data, the process of processing the process in collaboration between the process , Manufacturing equipment CNC and integration of production information. At the same time, promote CNC and intelligent transformation of key processes and key equipment, and build high -efficiency coordinated digital workshops.

In order to ensure product quality, Qingdao Shuangrui has also established a lean quality control system, based on the standardization of inspection work, relying on the production and manufacturing execution system to establish a quality data online monitoring system to achieve quality monitoring of the manufacturing process; rely on the supplier relations management system to achieve supply supply Commercial collaborative management to improve the quality control level of outsourcing materials.

"Through the resource allocation system with resource plans, the company has formed an integrated business platform with project management as its core, which has strengthened the full process control from design to product delivery." Dong Ruyi said that the company has established production and operation command centers to produce production and production and production and production. The cycle was greatly shortened, and the execution cycle of the pressure -loading water project was shortened from 210 days to within 60 days; the timely production delivery rate increased from 42%to more than 90%, and the inventory decreased by 83%.

"On high -quality development channels, only by practicing internal and external merits can we make Chinese manufacturing towards China’ s intellectual manufacturing and make a famous hall in the international market. "Fu Hongtian said.

Layout green track

Today, strengthening ship pollution prevention and application of green clean energy has become a consensus on the global shipping industry. Compared with traditional ship fuels, the current widespread clean energy liquefied natural gas (LNG) can greatly reduce the pollution of the ship's tail gas to the environment, but there are still many challenges to use it as a ship's power fuel.

According to Fu Hongtian, in the special application environment of the ship, the liquefied natural gas gas supply system needs to solve technologies such as liquefied natural gas low -temperature storage, stable gas supply and safe use of liquefied gas. Due to the transformation of liquid -gas phase, the liquefied natural gas supply system of dual fuel engines is different from the fuel supply system of traditional engines. It has more composition equipment, more complicated workflow, and greatly increased danger. Qingdao Shuangrui has formed a R & D team of liquefied natural gas gas supply systems, which lasted for 5 years and successively overcome a number of core technologies such as liquefied natural gas storage, gas pressure regulation, vaporization temperature control, flash steam treatment, automatic control and simulation platform development. Low -voltage, high -voltage, and self -booster liquefied natural gas gas supply system products are suitable for all types of liquefied natural gas power ships.

"The design, production, installation and debugging cycle of LNG gas supply system is long. Only when the real ship's debugging stage can the function of the entire system be verified. Once the error occurs, the system rectification costs are high." This problem, relying on digital twin technology, the R & D team has developed a LPG natural gas gas supply system simulation platform. Through the platform, the system can simulate the system to achieve process parameters, equipment selection, and control logic optimization.

At the same time, the company builds a land -based test base for liquefied natural gas gas supply systems, which can be used to test the functions of liquefied natural gas gas supply systems, verify the rationality and reliability of system performance indicators and solution design, and achieve continuous improvement of the product.

Relying on the simulation simulation platform and land -based test base, Qingdao Shuangrui has achieved leapfrog development in terms of design capabilities, application experience, production layout, delivery capabilities, etc.

"LNG is generally considered to be a feasible alternative fuel in the future, and clean energy such as ammonia fuel, hydrogen fuel, etc. also attracts much attention. In the future, it may become the first choice of shipping." Fu Hongtian told reporters that "no matter how good products have life, there will be life in life. After a certain period of time, we will become backward. For this reason, we have always insisted on exploring zero carbon fuel. "In July of this year, the ship's ammonia fuel supply system independently developed by Shuangrui, Qingdao, obtained the British Lourai Class Society and the China Shipping Club Principle recognition certificates, this is a major breakthrough in the company in the field of ship's clean energy supply system.

"To achieve high -quality development, it is inseparable from continuous innovation. Continuous innovation refers to the continuous improvement and upgrading of the original products of the enterprise, and it also refers to a new, larger and faster innovation in the process of innovation, or more and faster innovation, or in other words, or in other words A disruptive innovation. "Fu Hongtian said," We will always adhere to the original mission of 'continued to improve the marine environment with technology and innovation, and continue to innovate, and contribute China's power to the green development of the global shipping industry.
