Development of deepwater oil and gas resources of the South China Sea is not only an urgent need for energy security, but also the necessary measure to protect the rights and dignity of China in the South China Sea as a sovereign state. For the development of ocean economy and the construction of ocean power, ocean equipment must be considered first. Ocean engineering equipment is the main body of ocean development equipment, which is among the four categories of ocean equipment. Deepwater area of the South China Sea is broad, and the ocean is very rich in oil and gas resources. However, the geographical environment in the South China Sea is very complex, and the deepwater area is far away from the mainland. According to the geographical environment features of the deepwater area of the South China Sea in China, the main technical features of adaptive deepwater ocean engineering equipment are analyzed, and several suitable operation modes for the deepwater ocean oil and gas resources development are introduced. This research may provide certain reference for the deepwater oil and gas resources development in the South China Sea.
