China News Service, Harbin, August 14 (Reporter by Liu Tao and Shi Yifu) Harbin Engineering University announced on the 14th that the team of Professor Wang Liquan of the Institute of Underwater Operation Technology and Equipment of the School of Mechatronics has developed the "most powerful brain" for underwater oil and gas exploration— -The core control equipment of the underwater production system has been delivered and will be used in the Bohai oil and gas field development project.
The Bohai Sea is rich in oil deposits, but the water channels are vertical and horizontal, and it is impossible to adopt the direct mining method of traditional offshore platforms. The use of underwater production systems is the best way to realize subsea oil and gas exploration and transport oil and gas to long-distance offshore platforms.
In the complex submarine environment, how to safely and reliably realize the control of oil and gas production equipment is the core key. This core technology is known as the submarine control module (SCM) in the industry.
Because underwater operations require extremely high standards for equipment safety and reliability, once a leakage problem occurs, it will cause serious damage to the marine ecology.
Faced with this high-risk and high-tech research, China's domestic universities and research institutions are rarely involved.

As the "brain" of the underwater control system, the underwater control module (SCM) is a device that integrates mechanical, electrical, hydraulic, and optical. From the details of the equipment to the overall system, it must withstand the test of high temperature, high pressure, and high intensity shock and vibration. , Need to solve multi-disciplinary problems.
The team from the Institute of Underwater Operation Technology and Equipment of Harbin Engineering University has made breakthroughs in underwater high-pressure integrated hydraulic valve plates, automatic and precise docking of underwater multi-channel hydraulic electrical circuits, intelligent monitoring of underwater power supply units and multi-channel data processing in the main control station, etc. A number of core technologies have successfully developed the underwater control module (SCM), main control station, power unit and installation and recovery equipment with independent intellectual property rights, and successfully developed the "most powerful brain" for underwater oil and gas exploitation.
This equipment is China's first domestically-made underwater control system used in the development of the Bohai Sea oil and gas field. Its various indicators have reached the same international level, and it has been certified by the Det Norske Veritas (DNV).
It marks an important breakthrough in the localization of China's high-end offshore oil and gas key equipment, opening up a new mode of shallow water oilfield operations.
