my country's first intelligent offshore drilling platform completes offshore installation

In recent years, CNOOC has developed the Wushi 17-2/23-5 oil field group joint development project, the Bozhong 26-6 oil field development project (Phase I) and the Huizhou 26-6 Oil field development projects and other intelligent demonstration projects will be used as a starting point to accelerate the construction of intelligent oil fields. The Huizhou 26-6 drilling and production platform is the first intelligent drilling and production platform independently designed and constructed by CNOOC. Through intensive design, it integrates intelligent image processing devices, edge intelligent computing stations, data storage and communication devices, data security management and control devices, data collection Internet of Things platform and other five intelligent modules, the number of intelligent devices is three times that of the traditional platform. However, the space occupied is reduced by one-third, which can increase production efficiency by 20% and reduce operation and maintenance costs by 10% every year, further establishing a new generation of "intelligent, safe and efficient" offshore oil and gas production operation mode.

The Huizhou 26-6 platform is equipped with CNOOC's first online simulation model, which can realize operating parameter optimization, intelligent control and other functions. It is like a "super brain" that can control real-time Simulate the production data to calculate the optimal parameters of each equipment, and command each production link with authorization. It is worth mentioning that this model can also greatly reduce the energy consumption of key equipment such as natural gas dehydration and slug flow control. This alone can save nearly one million yuan in operation and maintenance costs every year.

High-precision smart sensors can collect equipment operating data and status evaluation data in real time and form a historical database, providing a solid foundation for equipment fault diagnosis. The fault diagnosis system applies artificial neural networks to allow the machine to have self-learning capabilities. Based on various types of automatically collected data, it can provide the best "treatment plan" for different fault types, thereby greatly improving equipment maintenance efficiency.

CNOOC independently designs and develops intelligent inspection function modules and develops the "one-click inspection" function to realize intelligent monitoring of people, machines, objects and the environment, greatly reducing manual labor. Inspection frequency. At the same time, the layout of optical equipment on the platform is intensive and efficient. The Huizhou 26-6 platform only needs to deploy half the number of previous platforms with the same specifications, such as more than 50 smart cameras or thermal imagers, to have the same capabilities.Monitoring capabilities enable automatic alarms for dangers such as fires and oil spills.

According to statistics, the upper module of the floatover installation that has been completed this time weighs about 17,000 tons, is 93 meters long, 42 meters wide, and 42 meters high. The projected deck area is equivalent to 8 Standard basketball court size. The modular construction uses the "digital management + integrated construction" model and innovatively applies precise three-dimensional modeling technology, with the integrated installation rate reaching 96%. Since the weight of the module exceeds the limit of the floating crane lifting capacity of offshore ships, the project team relied on the natural force of tides and construction techniques such as ship load adjustment to install the module into the duct as a whole through a floatation method similar to the "clean and jerk" of a weightlifter. stand at the predetermined position.

This floatover operation coincides with the peak monsoon season. The construction team seizes the time window, monitors the weather conditions in the operating sea area in real time, fully links the anchor windlass, tugboats, etc., and dynamically adjusts the progress of the operation vessel. The speed and direction of the ship, and the docking accuracy between the module and the jacket reach millimeter level.

The Huizhou 26-6 oil and gas field is my country’s first major exploration breakthrough in the new area of ​​ancient buried hills in the Pearl River Mouth Basin. After the project is put into production, it will effectively enhance the clean energy supply capacity of South China.
