World submarine cable map 2019 version officially released before today. The new map depicts 420 submarine cable systems and 1,106 cable landing stations in the world today, including those that are already in operation, under construction, and are expected to be put into operation by the end of 2021.
  
World Submarine Cable Map, Version 2019
According to TeleGeogram, which is responsible for the preparation of the 2019 edition of the world submarine cable map, 107 submarine cable systems were deployed globally between 2016 and 2020, with a total length of more than 400,000 kilometers and a total value of more than 13.8 billion U.S. dollars.
In the exhibition hall of Qingdao Han cable Co., Ltd., there is a special sample, which passed the inspection and acceptance successfully in the province's major scientific and technological projects on January 21, that is, marine dynamic cables supporting deep-sea oil recovery equipment under 3000 meters. "This product breaks the foreign technology monopoly in this field and extends domestic cables from only 300 meters below sea level to 3,000 meters below sea level. "Duanweixi, the technical leader of the project, told reporters that through the implementation of the project, he has completed key technical tasks such as the structural design and analysis of umbilical cord cables, dynamic cables, and ultra-high voltage photoelectric composite sea cables for marine engineering, and established a key technology system with independent intellectual property rights. It is of great strategic significance to develop deep water oil and gas field in the South China Sea and to ensure the energy security of China.
  
Break the foreign technology monopoly
"When it comes to the ocean dynamic cable that has just been successfully accepted in the major provincial science and technology projects, Duanwei, the head of the project's technology, has been gushing to introduce to reporters that the cable can be applied to an environment with a water depth of 3,000 meters, which is 10 times that of domestic mobile cables., With a service life of not less than 30 years, the application of this project can provide better guarantees for the development of offshore oil recovery platforms to deep water.
  
"Dynamic cables are the lifeline connecting floating platforms and underwater production systems. Their role is to provide power, control signals, fiber optic information, and data transmission channels for underwater production systems of offshore oil production platforms. "
"Prior to this, all our ocean dynamic cables came from imports. The completion of this project has not only broken this monopoly, but also greatly saved our country's deep-sea survey expenses. "Duanweixi is quite proud to say that in the past, China could only produce static cables that were adapted to depths within 300 meters. However, with the continuous progress of deep-sea exploration, the development of deep-water marine resources has become a general trend, and it is difficult to adapt to static cables for short-distance and shallow sea development. Meet the demand.
  
Duanweixi told reporters that the project took two years to overcome many key technical problems such as multi-layer armor torsion balance analysis and dynamic cable structure design, and developed a set of dynamic cable section design and mechanical analysis numerical simulation software. A set of marine dynamic cable manufacturing technology and technology with independent intellectual property rights has been formed, and a new dynamic cable that can be used in marine engineering has been successfully developed.
  
Indirect industrialization achievements 470 million yuan
"The team took on the major special project in Shandong Province in 2015 and began research and development of the ocean dynamic cable project. It took two years to develop and put into production. Zhang Tao said that after two years of efforts by the R&D team, all the variables were finally perfectly combined and the ocean dynamic cable project was successfully completed. At that time, it became the first company to produce marine dynamic cables in China. Since then, through the implementation of the project, a dynamic cable production line for marine engineering has been built, with an annual production capacity of 300 kilometers.
According to Zhang Tao, deputy chief engineer of Qingdao Hanfeng Co., Ltd., the research and development team of the project totaled 24 people, the youngest 30 years old and the largest 60 years old. They are senior engineers. The team members involve materials, machinery, cables and other professional fields., Has extensive experience in marine engineering cables and deep-sea engineering.
  
"The seabed environment is complex and changeable, and the pressure, sealing and strength requirements of the cable are extremely high; The cable engineering involves many links such as development, production, construction and maintenance. The deployment period is long and the investment is large. Each link requires special technology and equipment. The reliability of the product requires very high. Zhang Tao said that during the implementation of the project, the development and industrialization of 6 series of products such as 3 varieties and 6 series of marine dynamic cables supporting deep-sea oil recovery equipment under 3,000 meters were completed. The products developed have successively been used in the tidal energy generation project of Zhaitang Island, the dynamic submarine cable of Yantai Yinhai tidal energy, and the AC submarine dynamic cable of Guangzhou Energy Institute. The dynamic cable of Tianjin Zhonghai Oil cathodic protection system has been put into use, and the indirect industrialization has reached 470 million yuan. The profit tax is 30 million yuan.
