Abstract: An overtensioning fastening tool to maintain control of oil and gas equipment and prevent migration upon failure. The overtensioning fastening tool is comprised of one or more flapper components, housed in a primary enclosure, a hydraulic deployment system and/or electric deployment system, housed in a secondary enclosure, a sensor, and a manual activation component. The overtensioning fastening tool is designed to grip and hold equipment and tooling, such as cables.

Abstract: An overtensioning fastening tool to maintain control of oil and gas equipment and prevent migration upon failure. The overtensioning fastening tool is comprised of one or more flapper components, housed in a primary enclosure, a hydraulic deployment system and/or electric deployment system, housed in a secondary enclosure, a sensor, and a manual activation component. The overtensioning fastening tool is designed to grip and hold equipment and tooling, such as cables, to prevent loss into the wellbore and to maintain the safety and integrity of the rig and surrounding rig environment.

Abstract: The present development is a system (10) substantially submerged in a liquid such as water. It includes a plurality of bags (50) connected to a rotating belt (40) each injected with air (A) such that as each bag rises, it pulls the belt upwards. The turning belt drives a wheel or sprocket (20) connected to a drive (22) shaft which is, in turn, connected (21) to a generator (25) for generating energy in a well-known manner. After the inflated bags (50) have risen towards the surface (WL) and as they are being redirected downwardly by the return side of the belt (47), they (50) are deflated. They (50) are then moved by the belt (40) to a position (46) wherein they get inflated (70,72,74) again and rise.

Abstract: An overvoltage fastening tool is disclosed having a quadrangular and parallelepiped-shaped container (A), a sensor (B), and a manual operating means (C).
