Giàn khoan tự nâng PV DRILLING VI

PV DRILLING VI là giàn khoan tự nâng thế hệ mới nhất và là phiên bản nâng cấp từ thiết kế MOD V B Class của Keppel FELS. Được đóng mới hoàn thiện vào tháng 2/2015, giàn PV DRILLING VI có thể khoan đến 9,000m ở mức nước sâu tối đa 121m, có tải trọng khoan kết hợp tối đa lên đến 2,500 kips (1,134 MT) cùng nhiều tính năng kỹ thuật vượt trội khác. Toàn bộ các trang thiết bị trên giàn đều được cung cấp bởi các đối tác có uy tín hàng đầu thế giới như National Oilwell Varco, Siemens, Catepillar, Favelle Favco, v.v… để đảm bảo độ tin cậy cao nhất và giảm thiểu tối đa các sự cố hỏng hóc gây ảnh hưởng đến việc vận hành liên tục của giàn khoan. Giàn khoan PV Drilling VI sở hữu bởi liên doanh giữa PV Drilling và các đối tác uy tín tại Singapore với mục tiêu chiến lược cung cấp dịch vụ khoan chất lượng cao cho thị trường khu vực và thế giới.
