The paper had discussed on a new technology and equipment in deepwater engineering, ASDD (Artificial Seabed Deepwater Drilling), and its process of commercialization in COSL of China. The concept of ASDD had put forwarded by a Norway engineer in 1993, and COSL had introduced it to China since 2004 from Europe, which has been built the cooperation with a company from Norway to develop ASDD not only the technology but also equipment. The advantages of ASDD is both reduce cost of drilling in deepwater and use common semi submersible to replace of expensive platform in deepwater drilling until water depth of 1500 m. A series of tests and simulations had been done both abroad and domestic by COSL and two large trial operations had been gone in South China Sea between 2008 and 2009. The trial well operation had been completed in Apr. of 2009, and COSL dispatched many huge vessels, including to Nanhai V, which is one of the hugest semi submersible in Aria, and AHVs that power is over 10,000 HP, such as Nanhai 212, Nanhai 213, Nanhai 216 and so on. The trial well had taken great success. It is obvious that COSL intend to carry out process of commercialization for ASDD, and the two commercial wells had been planed to drill in South China Sea in 2010.
