"Deep Sea One" has become the world's first ultra-large deepwater semi-submersible production and storage platform with remote control production capabilities.

"At present, the production and processing equipment of the 'Deep Sea?' has reached the best operating condition after careful debugging. The biggest challenge facing the stable production of the gas field is the frequent typhoons in summer and autumn." CNOOC Hainan The relevant person in charge of the branch Lingshui-Yacheng Operation Company said that the ultra-deep water semi-submersible platform has a complex structure and harsh environmental conditions. After a strong typhoon approaches and personnel evacuate the platform, it is difficult to maintain the operation of oil and gas production equipment like a shallow-water offshore gas field. There has been no successful case in the world of remote control production of typhoons on a deepwater semi-submersible platform.

According to reports, CNOOC positions the "Deep Sea?" as the main gas field guaranteed to supply "from sea to land" in South China, and plans to give it remote control production capabilities and put it into production in the gas field. After that, we quickly invested technical resources to implement typhoon mode transformation, in order to minimize the impact of typhoon shutdowns on downstream users.

In the process of equipment transformation and upgrading, CNOOC vigorously promotes the application of digital intelligent technology, and analyzes storms through calculation and modeling in accordance with the principle of "comprehensive assessment, system design, and prudent implementation" Under the conditions, the overall performance of the platform and the strength of the mooring system, platform stability, status of the riser and umbilical cable, and the overall strength of the hull structure were determined. Key indicators such as the platform's storm draft safety range and the transformation of more than 270 sets of related equipment were determined. Commissioning plan, promoted the construction of "Deep Sea One" onshore control center and other supporting facilities, successfully implemented remote monitoring tests and remote control production tests under harsh sea conditions, so that "Deep Sea One" has remote control production capabilities, which can increase every year Natural gas production and supply exceeds 60 million cubic meters, which can be used by 470,000 households for one year.

“While implementing remote control production transformation, ‘Deep Sea One’ simultaneously carried out application exploration of a variety of digital intelligent technologies, and strived to build ultra-deepwater smart gas fields and createAn industry demonstration benchmark with leading technology. "The relevant person in charge of CNOOC Hainan Branch introduced that by establishing a digital twin model of the ultra-deep water gas field, technical experts can fully understand the operating status of "Shenhai No. 1" at the base production operation center and conduct remote diagnosis of equipment faults; through By upgrading the sound and light detection intelligent monitoring equipment, "Deep Sea One" will gain stronger real-time perception capabilities and establish a three-dimensional security system covering both water and underwater; and with the application of 5G equipment on the platform, "Deep Sea One" will be built on-site With the industrial Internet of Things application scenario with 5G technology as the core, various devices on the platform can be interconnected, and on-site operators can control the operating status of the energy station in real time through 5G smart mobile terminals.

It is understood that the "Deep Sea No. 1" energy station, as an oil and gas production facility, is also a large-scale comprehensive experimental platform for scientific research. CNOOC aims at semi-submersible platform hull berthing management and deep sea gas encountered in the development of deep sea oil and gas resources. To solve world-class technical problems such as dynamic monitoring of Tibet development, guarantee of deep-sea underwater mobility, and visual management of deep-sea production operations, we use "Deep Sea No. 1" to carry out scientific experimental research. At the same time, we maintain close contact with domestic and foreign research institutions and universities to jointly carry out digitalization. Research on the application of intelligent technology in ultra-deep water gas fields creates good conditions for enhancing the core competitiveness of China's deep-sea energy industry and promoting the high-quality development of the offshore oil and gas industry.
