考虑具体的海洋环境条件，依据API RP 2A－WSD规范，初步设计地处南海的65 m水深井口平台的导管架结构，对导管架结构进行安全校核。确定导管架的结构形式和尺寸，以结构重量为目标函数，API规范要求为约束条件，管径和壁厚为设计变量，采用一阶寻优法对导管架结构进行尺寸优化。
攷慮具體的海洋環境條件，依據API RP 2A－WSD規範，初步設計地處南海的65 m水深井口平檯的導管架結構，對導管架結構進行安全校覈。確定導管架的結構形式和呎吋，以結構重量為目標函數，API規範要求為約束條件，管徑和壁厚為設計變量，採用一階尋優法對導管架結構進行呎吋優化。

The jacket structure of a wellhead platform located at the South China sea with water depth of 65 m under the specified marine environment is designed according to the API RP 2A-WSD specification.The safety of the structure is also checked.The pipe diameter and wall thickness of the jacket structure are optimized by using the first-order optimization method, taking the structure weight as the objective function, and taking the requirements in API specification as constraint conditions.
