Giàn khoan TAD - PV DRILLING V

Giàn khoan TAD - PV DRILLING V là thế hệ giàn khoan hiện đại nhất hiện nay thuộc model SSDT 3600E HP được đóng bởi công ty đóng giàn lớn nhất thế giới và duy nhất hiện nay về thiết kế giàn khoan tiếp trợ nửa nổi nửa chìm (TAD). Giàn khoan TAD đầu tiên trên thế giới được đóng bởi KFELS vào năm 1994 và tính đến thời điểm đóng giàn PV DRILLING V đã có 7 giàn khoan loại này được đóng bởi KFELS với model SSDT 3600E. Giàn khoan PV DRILLING V của PV Drilling là giàn khoan TAD thứ 8 trên thế giới và thuộc thế hệ giàn khoan TAD hiện đại nhất hiện nay với Model SSDT 3600 E HP. Đây là thế hệ giàn khoan TAD được ứng dụng nhiều tính năng vượt trội, công nghệ cao so với các giàn khoan tiếp trợ hiện hữu.

Đây cũng là giàn khoan đầu tiên trên thế giới ứng dụng công nghệ cao để khoan các giếng khoan nhiệt độ cao áp suất cao (HPHT) với công suất thiết bị chống phun (BOP) được thiết kế với áp suất làm việc lên đến 15.000 psi (tương đương 1020 atm) là những thách thức lớn của công nghệ khoan dầu khí hiện nay. Một điểm đặc biệt nữa là giàn khoan PV DRILLING V của PV Drilling có thể thực hiện được các giếng khoan đến độ sâu đến 30.000 ft (9.100 m) với độ sâu mực nước biển có thể hoạt động lên đến 4.000 ft (1.200 m).
