ABSTRACT:
A tube closure for use in a pile or leg connectable to the inside of a pile or leg between the ends of a pile or leg to divide the pile or leg into separate compartments to permit control flooding of each compartment. A locking ring is installed in the inside of the pile or leg to allow engagement of locking dogs with the pile or leg to limit longitudinal movement of the closure system through the pile or leg. The locking dogs are operably connected to a hub which when lifted moves the locking dogs away from the locking ring to disengage the system. An inflatable rubber packer is formed around the closure to seal off the area between the closure and the inner wall of the pile or leg. Once the piling or leg is in location, the rubber packer is deflated and the system is removed by a wire line which lifts a hub secured to the dogs to move the dogs out of engagement with the locking ring before lifting the assembly from its position. A valve is provided to allow equalization of the hydrostatic pressure across the plug by flooding prior to removal of the closure.
