(referred to as: Offshore Oil Engineering Company) learned that the upper module of the Huizhou 26-6 drilling platform built at the Zhuhai site of Offshore Oil Engineering Company has been accurately connected to the jacket and stands in the middle of the vast sea. The crude oil and natural gas stored deep in the seabed will be transported to thousands of households on land through this, lighting up the "Lights of Ten Thousands of Houses" in the Guangdong-Hong Kong-Macao Greater Bay Area. According to reports, the Huizhou 26-6 drilling platform is my country's first intelligent offshore drilling platform, with a total weight of over 30,000 tons. The upper block of the floatover 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 eight standard basketball courts. Wei Weirong, deputy general manager of CNOOC's Luhuixi project, said that because the weight of the upper module of the Huizhou 26-6 drilling platform exceeds the lifting capacity limit of the floating crane of offshore ships, the upper module was installed as a whole to the predetermined position of the jacket using the natural force of tides and construction techniques such as ship load adjustment, similar to the "clean and jerk" method of a weightlifter. It is understood that large offshore platforms installed with floats have significant advantages such as overall design, construction, transportation, and installation. They can significantly shorten the construction cycle and offshore operation time, significantly improve construction safety and economy, thereby promoting the efficient and rapid commissioning of offshore platforms. Li Tao, general manager of the Huizhou 26-6 oilfield development project of Offshore Oil Engineering Company, said that the floatover operation coincided with the high monsoon season in the South China Sea, with harsh sea conditions and a short operating window. To this end, the construction team seized the time window, monitored the weather conditions in the operating sea area in real time, made full use of the linkage between the anchor windlass and the port tugboat, and dynamically adjusted the entry speed and direction of the 'Offshore Oil 228' ship. The floatover operation was successfully completed, and the accuracy of the docking between the module tip and the jacket reached millimeter level. As the first intelligent drilling and production platform independently designed and constructed by CNOOC, the Huizhou 26-6 platform integrates five major intelligent modules such as "super brain", edge intelligent computing station, and data security management and control device through intensive design. It is equipped with 10 sets of subsystems such as process simulation optimization system, energy consumption monitoring and management system, and intelligent inspection system. The number of intelligent equipment is three times that of the traditional platform, but the space occupied is reduced by 1/3. It has a series of powerful functions such as intelligent production, intelligent drilling, equipment health management, and intelligent security. It can increase production efficiency by 20% and reduce operation and maintenance costs by 10% every year. It is reported that after the Huizhou 26-6 oil field development project is completed and put into operation, it will effectively enhance the clean energy supply capacity of South China, assist the economic and social construction of the Guangdong-Hong Kong-Macao Greater Bay Area, provide support for the development of surrounding newly discovered oil and gas fields, and contribute to ensuring my country's energy security and building a maritime power.
