摘要： A removable closure apparatus for tubular members of offshore platforms and the like utilizes a body inserted in the tubular member. A seal formed in an annulus between the inner surface of the tubular member and the outer surface of the body is bonded to each of the surfaces of the body and the tubular member. The seal is broken by use of a flexible tensile bearing inlay spirally embedded within the seal. The inlay is torn from the seal to destroy the structural integrity thereof and permit removal of the body. The inlay has one end affixed to the body and a second end extending upwardly through the member for manipulation from the upper end thereof. A force applied to the second end of the inlay causes it to tear the seal along a spiral path.

摘要： In an offshore platform to be erected on hollow legs which receive piles driven down through the legs into the ocean floor, a resilient diaphragm closure for each of said legs to prevent ingress of water as said platform is moved into position. The diaphragm includes a ring of down-facing cutter blades oriented in the upper surface of said diaphragm for registration with a down moving end of the piling to sever the diaphragm and facilitate passage of the end of the piling beyond the location of the diaphragm.

摘要： A float valve assembly comprises a valve body defining an internal chamber having upper and lower openings and a vertically movable ball or poppet in the chamber for moving upwardly to close the upper opening to prevent upward flow of fluid and for moving downwardly away from the upper opening to permit downward flow of fluid. A resilient, deformable seal positioned adjacent the upper opening has three separate seal elements to provide primary, secondary and tertiary sealing phases. The interior of the valve chamber is lined with a continuous liner to minimize abrasion of the valve. The liner and the resilient seal are formed simultaneously as a single unit by in-situ molding and curing of a thermosetting elastomer material.
