Ningbo Oriental Umbilical Cable Unveils China's Deep Sea

A few days ago, a good news came from Indonesia BLT Company. Photovoltaic composite umbilical cable developed and produced by Ningbo Dongfang Cable Co., Ltd. has been successfully "in service" for over one year on the offshore oil platform in Indonesia, and all performance indicators have fully met the design requirements.

Umbilical cable, like the "umbilical cord" between the fetus and the mother, is a key equipment in the field of oil and gas exploration, offshore engineering and other fields. It provides electrical hydraulic power and chemical injection channels for deep sea production systems, and provides data transmission channels. For a long time, the umbilicals used in China have all depended on imports. The key technology research is still blank.

In 2009, Dongfang Cable was already the largest submarine cable manufacturer in China. In order to break the monopoly of the world's giants, Dongfang Cable and CNOOC Co., Ltd. have entered the industry's most cutting-edge umbilicals field.

"The design of umbilical cable should take into account the functions of electricity, communication, hydraulics, etc. It must also meet the dynamic response requirements of complex sea conditions. Its material strength, corrosion resistance and penetration resistance are extremely high." Xia Feng, general manager of the Oriental Cable, said, "Underwater The research on the key technologies of the production system umbilical cable was therefore included in the national 863 plan.

In 2010, a dynamic umbilical cable damaged by CACT Huizhou Oilfield Project was damaged in the typhoon. In order to resume production as soon as possible, CACT invited a global tender. Dongfang Cable won the same stage competition with two multinational companies, and its design life span reached 25 years. , achieved the first industrialization and internationalization of the product.

“Our product prices have a certain competitive advantage, and the design and production cycle is even shorter than that of foreign companies.” Xia Feng said that this 4 km-long umbilical cable was used in the South China Sea. After undergoing frequent typhoon tests last year, the Umbilical cables have become famous in the international market.

Since then, Dongfang Cable has relied on its own submarine cable research institute and academician studio to carry out technical cooperation with well-known domestic and foreign colleges and universities, such as CNOOC Research Institute, Norwegian Marinetek, Dalian University of Technology and Shanghai Jiaotong University, through flexible talent recruitment and integrated innovation. Constantly seize the technical commanding height in the field of umbilical cord.

In addition to technological innovation, there are service advantages to assist Oriental Cable to seize the market. “If something goes wrong, it may take a month or two for the foreign company to complete the repair, and we promise to be able to get people in place within 24 hours.” Xia Feng said that this successfully won CNOOC and the National Grid for the company’s submarine cable products. , China Southern Power Grid and other major customers.

During the “Twelfth Five-Year Plan” period, with the acceleration of research on marine new energy development and deep-sea exploration and mining technologies, umbilicals at the forefront of cross-cutting technology will achieve rapid development. Xia Feng said that Dongfang Cable will focus on umbilical cable products and promote the localization of key equipment in deep-sea production systems, and make contributions to safeguarding China's energy security.
