Abstract: Interlocking bend limiter sections are substantially mirror images of each other and are joined to form an interlocking bend limiter segment without use of fasteners by engaging each other's interlocking ends. An interlocking bend limiter comprises a plurality of interlocking bend limiter segment secured at an end by an end piece. In alternative, related embodiments a repair system comprises one or more machinable length sections which function as chain clamps to repair a subsea pipeline while the subsea pipeline is still in service and which can comprise interlocking sections similar to bend limiter sections or which are locked in more traditional manners such as by using bolts or other fasteners.

Abstract: A pipe tool, useful for cutting, removing a weld, and/or truing a pipe, comprises a housing; a drive interface; a gripper selectively insertable into an inner annulus of a pipe and movable independently of the housing, the gripper comprising a selectively expandable grip; a radially disposed cutter adapted to selectively engage a predetermined portion of an outer surface of the pipe, the cutter movable independently of the housing and the gripper; and a motor operatively in communication with the drive interface. In embodiments, a pipe is cut by maneuvering the pipe tool proximate an open end of a pipe, moving the gripper into the pipe; extending the grip to engage an interior wall of the pipe and secure the pipe tool from movement relative to the pipe; advancing the exposed face to a predetermined position relative to the pipe; axially advancing the cutter to engage an outer wall of the pipe; and rotating the housing until the cutters perform the desired cutting operation on the pipe.

Abstract: A method of connecting pipe ends of two subsea pipes using a jumper includes raising two separate ends of two separate pipelines from an initial position of each of the two separate ends; creating a jumper pipe; welding a flange with a landing saddle to each pipeline end; disposing a predetermined number of cylinders at a predetermined interval offset with respect to each of the cylinders; connecting a cylinder end to a first leg of the jumper pipe; connecting a rod end to a second leg of the jumper pipe; using the cylinders to contract the jumper in a predetermined plane so that the flanges clear the pipe ends but not the flange saddles; supporting the jumper by a spreader bar; lowering the jumper over the pipeline such that the flange saddles rest on the pipeline ends; relaxing at least one of the cylinders so the jumper expands in the predetermined plane, driving the flanges onto the pipeline ends; releasing the spreader bar; and lowering the pipeline ends and jumper to a predetermined position.

Abstract: This invention is directed to a flange coupling member for connecting pipe sections, including subsea pipe sections. The invention uses an elastomeric band, a tapered cone ring and a tapered slip ring to provide a coupling capability. Additionally, the present invention uses a flange that is detachably connected to the housing.
