Enhance quality awareness and promote high-quality development. ----------------------------------------- For various production platforms used in offshore oil and gas exploration to be able to stay stable at sea, they not only need to be capable of withstanding strong typhoons but also must remain stable despite frequent waves. Steel piles serve as the “foundation” of a platform; laying a foundation underwater requires the use of pile-driving hammers to drive them into the ground. Especially when carrying out pile-driving operations in deep waters, in addition to being affected by wind, waves, and currents, such tasks also face challenges related to complex environments and variable geological conditions. This makes the construction process difficult and increases the risks associated with safe operation. On June 27, 2023, CNOOC reported that China’s first domestically developed 2,500-meter-class ultra-deep-water pile driving hammer successfully completed its sea trials and demonstration applications. This development filled the gap in domestic technology related to core equipment for ultra-deep-water pile driving, helping to advance China’s capabilities in underwater pile driving from deep-water to ultra-deep-water levels. It holds great significance for accelerating the exploration of deep-sea oil and gas resources and ensuring energy security. The ultra-deep-water pile driving hammer developed this time features a design operating depth that is the best in the world, enabling it to cover China’s major sea areas. Through nearly 3 years of research and development in collaboration with domestic scientific research institutions and universities, CNOOC Engineering has successfully overcome a number of key technical challenges, including the overall design of ultra-deep-water pile-driving hammers and the design and manufacturing of their core components. It has developed its own high-response control systems and advanced hydraulic control systems that enable precise control over the driving speed as well as autonomous positioning of the equipment. After undergoing various complex tests under conditions of high pressure, low temperature, and impact, the precision of position control has reached sub-meter levels, making its overall performance at the world’s advanced level. This self-developed ultra-deep-water hydraulic pile driver has a total length of 16.1 meters and a maximum diameter of 3.85 meters; its weight in air is 165 tons. During driving, it relies on an internal component called the \"hammer core\" to generate impact force, which is then transmitted to the pile. It features low energy consumption, minimal air pollution, and good adaptability in various working conditions.
