New year, new atmosphere, major sea and land projects have a good start

"Deep Sea No. 1" helps the development of marine resources

The development capabilities of deepwater oil and gas fields and the construction level of deepwater marine engineering equipment are crucial to A country's energy security and its ability to develop marine resources have a decisive impact. And just in January this year, my country's independently developed and built 100,000-ton deepwater semi-submersible production and storage platform, the "Deep Sea No. 1" energy station, was successfully delivered and set sail in Yantai, Shandong. This achievement is not only important for improving the development of marine resources. capabilities and supporting the strategy of becoming a maritime power are of great significance, and it also proves our country’s strength in deep-water ocean engineering.

It is understood that "Deep Sea No. 1" has a large oil storage capacity of nearly 20,000 cubic meters, realizing the integrated functions of condensate production, storage and export. In February this year, the energy station will implement on-site installation of oil and gas production facilities in the Lingshui waters southeast of Hainan Island for the development of the Lingshui 17-2 gas field (a 1,500-meter deep water self-operated large field).

The Beijing-Harbin Line and the "Alpine Warrior" Fuxing's amazing China speed

On January 22, with the With the official opening of the Beijing-Chengde section of the Beijing-Harbin high-speed railway, the Beijing-Harbin railway has been fully connected. It only takes 2 hours and 44 minutes and 4 hours and 52 minutes for ordinary people to take the high-speed railway from Beijing to Shenyang and Harbin. And if the completion of the Beijing-Harbin Line symbolizes Chinese technology and Chinese speed, then Fuxinghao may be a direct manifestation of Chinese technology and Chinese speed.

In order to cope with the driving needs of the Beijing-Harbin Line, EMUs used for transportation need to meet the needs of high-speed driving at low temperatures. The EMU used on the Beijing-Harbin line this time is the new Fuxing high-cold EMU with a speed of 350 kilometers per hour independently developed by CRRC Sifang Co., Ltd. It is understood that this cold-resistant special edition Fuxinghao adopts low-temperature-resistant design from the materials and components used to the body, bogie, wind supply brake and other key system components, and is in sealing, snow-proof and Improvements have been made in aspects such as impact, liquid system antifreeze, and condensation water prevention.It can achieve a speed of 350 kilometers per hour in an environment of minus 40 degrees Celsius.

The completion of the Beijing-Harbin line and the emergence of the new Fuxing high-cold EMU also mean that from now on, the high-speed EMU will provide the public with a way to experience the northern scenery and appreciate the scenery all the way north. With the great opportunities of the motherland, people do not have to worry about transportation restrictions in terms of distance and temperature.

"The First Tunnel of the Yellow River" helps to cross the Yellow River in 4 minutes

Although it is necessary to use a tunnel to connect the Yellow River, It sounds like a fantasy, but it has been successfully achieved recently. On January 23 this year, as the "Huanghe" shield machine broke through the ground, the western tunnel of the Jinan Yellow River Tunnel Project was successfully completed. At the same time, this also marks that the large-diameter highway-rail combined shield tunnel under construction in our country has been fully connected. It is reported that the tunnel is planned to be completed and opened to traffic in October this year. By then, it will only take 4 minutes to drive across the Yellow River.

From a technical perspective, the construction of this "First Tunnel of the Yellow River" is not only difficult to construct, but also requires a series of technologies such as geology, big data, and the Internet of Things. The test involves many smart devices. But there is no doubt that we succeeded.

From the ocean to the land, the development of technology has provided assistance for the construction of major projects, and the completion of the projects has brought more convenience to our lives. What behind each "good start" is not only the development of our country's strength in recent years, but also the bright future that can be expected.
