Development history of submarine flexible composite pipe

Submarine pipelines are the lifeline of offshore oil and gas fields and play an important role in the development of offshore oil and gas fields. As a type of submarine pipeline, marine hoses have been widely used in the development and construction of offshore oil and gas fields because of their good power performance, corrosion resistance, ease of installation and laying, and recycling and reuse. In order to break the technical bottleneck restricting the development of the domestic marine hose industry and breakthrough the foreign blockade, our company independently carried out the research on the key technology of the marine hose and the development of the marine hose. In 2010, the first marine hose product manufactured by the company was successfully applied in the western waters of the South my country Sea. "Made in China" began to break through the domestic technical blockade of international marine hose manufacturers. So far, its products have been used in more than a dozen oil and gas fields in my country's South China Sea, Bohai Sea, and the East China Sea, providing products and technical support for the development of my country's offshore oil and gas fields, especially the development of deep-sea oil and gas fields. From 2017 to 2018, the company opened up foreign markets in Southeast Asia and South America, developed dynamic marine hoses necessary for deep-sea oil and gas field development, and applied it to Petronas two times. Exported to Venezuelan oil companies twice this year, domestic marine hoses began to rush out of Asia, and "Made in China" rushed out of Asia to raise the country's prestige.

In order to break through foreign monopolies and technological blockades, the company invests a large amount of money in technological innovation and research and development every year. The investment in laboratories and test equipment alone exceeds 20 million yuan, establishing the country's first marine hose pipe material The test center and prototype test workshop, with a total of more than 100 experimental and test equipment (sets), have met all the experimental requirements for material experiments and prototype tests specified by the international standards for marine hoses, and the company has made considerable progress in technology. In 2012, the company obtained the marine composite hose product monogram certification (API 17J) issued by the American Petroleum Institute (API). Like the three foreign companies, it has an internationally recognized marine hose design and manufacturing certificate. Since 2012, the company has inherited the “Key Technology Research of Thermal Insulation Oil Pipeline Hose” project led by the CNOOC Research Institute in the 12th and 13th Five-Year Plan. In 2015, the company's products obtained the 8-inch dynamic hose type approval certificate from the French Bureau of Shipping (BV), and the company has the ability to manufacture high-end marine composite hoses. So far, 19 patients (including 4 invention patents) have been obtained, and a complete industrial chain from the design and production of various types of marine static and dynamic hoses to deepwater paving system services has been established, and the entire industrial chain of marine hoses except for some raw materials has been realized. Localization.

At the same time, the company has always mastered and has the core technology of independent intellectual property rights of marine hoses for standard science and technology innovation board enterprises, has an efficient research and development system, and has continuous innovation capabilities. It has broken through the key core technology of marine hoses and is conducting technical research on marine dynamic hoses at a depth of 1,500 meters. It has a relative competitive advantage and breaks through the foreign technology blockade. The core management team and technical team are stable and competitive in China and have gradually gained competitive advantages in foreign markets. Have the conditions to transform technological achievements into business results. Over the years, in the continuous transformation and application process of continuous research and development, a series of products such as static marine hoses, thermal insulation marine hoses, large-caliber marine hoses, and dynamic marine hoses have been formed, forming a business model conducive to the continuous operation of the company.
