Nandu News The reporter just learned from CNOOC Deep Sea Development Co., Ltd. that the company's Baiyun natural gas operation company Gaolan Terminal in Jinwan District successfully completed the submarine pipeline exploration operation by sending "frogmen" to dive operations, which effectively guaranteed the demand for power generation, industry and people's livelihood gas in the Guangdong-Hong Kong-Macao Greater Bay Area.
The eastern part of the South China Sea is rich in oil and gas resources and is an important oil and gas production area in China and offshore. As the largest natural gas production base in the Guangdong-Hong Kong-Macao Greater Bay Area, Baiyun Natural Gas Operation Company is responsible for the task of supplying gas to nine cities in the Guangdong-Hong Kong-Macao Greater Bay Area. Liwan 3-1 gas field, Panyu 34-1 gas field, Panyu 35-1 gas field and other natural gas fields supply residential gas in the Guangdong-Hong Kong-Macao Greater Bay Area through landing and deep processing from Jinwan District of Zhuhai City, and the annual output of natural gas has remained above 6 billion cubic meters in recent years, and the export volume of natural gas accounts for nearly one-fifth of the total natural gas sales in Guangdong Province.
According to reports, the Liwan 3-1 platform to the high-fence terminal sea pipe that carried out the submarine pipeline exploration operation is an important part of the supply of oil and gas resources in the South China Sea Greater Bay Area, and regular inspection of pipelines is an essential link to ensure gas supply safety. In this inspection, the sea pipe detection of the landing section of the high fence terminal was carried out underwater by sending "frogmen" to dive into the water.
Diving is one of the most dangerous jobs humans do. In addition to breathing problems, divers also face harsh working environments such as high pressure, darkness, currents, surges, and harmful marine life. In this near-shore section dive, divers wearing professional diving equipment and carrying special maintenance tools dived underwater to explore the situation of the sea pipe, and with the cooperation of the operators of the high fence terminal, they completed the detection of the protective layer of the sea pipe and the detection and inspection of the anode block.
Faced with complex situations such as unstable sea conditions, long operation cycles and many cross-operations during the operation, Baiyun Natural Gas Operation Company actively responded, coordinated the deployment of various operations, and provided a "golden window period" for diving operations to ensure the safe and efficient development of operations.
