An assembly and method for drilling micro holes in a tube including an outer wall having opposing open ends and forming an inner channel. The method includes the steps of submerging the tube in water so the water fills the inner channel, retaining the water in the inner channel, freezing the water in the inner channel so as to form an ice backing in the inner channel, and drilling through the outer wall such that the ice backing supports the outer wall and prevents the outer wall from deforming or distorting near the hole location.

A method and apparatus for tapping into a pressurized multiple strings of coaxially situated tubulars for wells and/or platforms which have overturned wherein the tapping occurs underwater via a diver or remotely operated vehicle. The assembly includes a tapping tool connectable to the tubular via a saddle connection and an adjustable tapping clamp with adjustable support/locking feet, compression plate with view ports, and angularly adjustable hot tapping system, along with a drill/saw system.

A machining system configured to reduce spring back following machining operations comprising a machining tool and a spring back control system. The spring back control system comprises a number of force generators and a number of force loaded members coupled to the number of force generators, each force loaded member of the number of force loaded members comprising a material contact surface.

An orbital drill bushing adapter for use with a drill unit. In one embodiment, the orbital drill bushing adapter comprises a main body and locking arms. The main body includes a base member having an upper surface, a lower surface, and an external side wall that extends between the upper surface and the lower surface. The main body further includes a cylindrical spacer that projects from the lower surface of the base member, and is configured to fit in a drill hole of an orbital drill bushing. The main body includes a cylindrical hole that passes through the base member and the cylindrical spacer. The locking arms are pivotally coupled to the base member, and are configured to clamp the main body onto the orbital drill bushing.

A cutting head attachment assembly for a cutting tool includes a body forming an axially forward part of the cutting tool attachable to a cutting head via a clamping element and a fixation element. A guide surface provided at the body or cutting head extends in both a radial and an axial direction to support movement of the clamping element in both the radial and axial directions via actuation of the fixation element to force and clamp together axially the head and body.

A clamping device for clamping a workpiece or a tool or, more specifically, a tool holding fixture in a machine part of a machine tool includes a tension rod slidably mounted within the machine part; a clamping set movable by the tension rod between clamped and released positions; a tension spring dedicated to the tension rod so as to generate the pull-in force of the clamping set; and a release mechanism, by which the clamping set can be moved against the force of the tension spring into the released position by the tension rod. To make possible effective clamping at optimum force, the tension spring is clamped between first and second rod parts of the tension rod. The second rod part can move relative to the first rod part, and, as the clamping set moves into the released position, is compressed on both ends by the release mechanism by moving the two rod parts in opposite directions.

A method and apparatus for angularly drilling during a tapping procedure into a pressurized multiple strings of coaxially situated tubulars for wells and/or platforms which have overturned wherein the tapping occurs underwater via a diver or remotely operated vehicle.

A tool including a pair of rails is attachable to the inside surface of the skin panel. A housing is pivotally and slidably connected between the pair of rails. The housing is pivotable about a first axis and is slidable along grooves in the pair of rails. The housing has a first end and a second end opposite each other. The tool includes a rod having a third end and a fourth end, the third end attached to and extending from the first end of the housing. The tool also includes a pressure foot attached to the fourth end of the housing. The pressure foot includes a curved ankle integrally formed with a flat flange, the curved ankle curving into the flat flange. The pressure foot is configured to apply pressure along a portion of the inside surface of the skin panel when the housing is in a vertical position.
