ABSTRACT:
A pressure actuated flow control valve for use in conjunction with inflatable packers and grouting systems on offshore oil platforms. The valve includes an elongated body with a plurality of pistons slidably disposed in the body between first and second positions, each piston being positioned adjacent a corresponding discharge port on the body. When in the first position, the piston sealingly closes the corresponding discharge port. When the piston is in the second position, the piston sealingly closes another discharge port adjacent the corresponding discharge port. A plurality of sleeves are annularly positioned around each of the pistons. First and second pressure lines are provided in communication with volumes adjacent opposite ends of pistons such that alternate pressurizing of the first and second pressure lines results in sequential movement of the pistons from the first to second positions. Interaction of the sleeves with the pistons provides that the pistons will only move from the first position to the second position and reverse movement thereof is prevented. An inflation system, a grout system, an offshore platform and a template for a tension leg platform utilizing the pressure actuated flow control valve are also disclosed.
