China's first, successful sea trial!

On June 27, according to the information of Offshore Petroleum engineering Co., Ltd,The first 2500 meter level ultra deep water pile hammer independently developed by China has successfully completed sea trials, filling the technical gap in the core equipment of ultra deep water pile driving in China.

The pile hammer is a key equipment for various platforms such as offshore oil and gas, wind power, etc. to lay the "foundation" on the seabed. The ultra deep water pile hammer used in this sea trial has a self weight of approximately 165 tons and a pile diameter of up to 2.5 meters. When driving a pile, it relies on the internal structure of the "hammer core" to impact and distribute the generated impact force to the pile body. Under a huge sea water pressure equivalent to 250 atmospheres, it can be hammered thousands of times in the fastest 3 hours. A 100 meter long "steel pile" can be driven into the seabed, which has the advantages of low energy consumption, low pollution, and strong adaptability.

The designed operating water depth of the ultra deep water pile hammer developed this time can cover the main sea areas of China, and has successively conquered several key technologies such as the overall scheme design of the ultra deep water pile hammer, the design and manufacture of key core components, etc. The accuracy control of the operating position has reached the sub meter level, and the comprehensive performance has reached the Vanguard International Semiconductor Corporation level, which is of great significance for accelerating the development of China's deep-sea oil and gas resources and ensuring China's national energy security.
