A pipe splitting assembly includes an articulating hammer nose assembly having a pipe splitting cutter and a rotatable joint coupled with the pipe splitting cutter. A pneumatic hammer is distal to the articulating hammer nose assembly. The pneumatic hammer is configured to drive the articulating hammer nose assembly proximally away from the pneumatic hammer. The rotatable joint is coupled between the pipe splitting cutter and the pneumatic hammer, and the articulating hammer nose assembly is rotatable into one or more angles relative to the pneumatic hammer through the rotatable joint. A cable coupling is interposed between the pneumatic hammer and the articulated hammer nose assembly. The cable coupling is configured to attach a cable to the pipe splitting assembly. The cable coupling and the rotatable joint are configured to transmit to the pipe splitting cutter a compression force from the cable coupling and dynamic percussive forces from the pneumatic hammer.

A restraint system for use in securing temporary flow lines that include multiple pipe sections, each pair of pipe sections connected together with a fitting or coupling such as a hammer joint coupling. The system includes multiple pluralities of endless loop slings connected end to end with a cow hitch or girth hitch knot. Disconnectable fittings (e.g., shackles) are placed every three or more slings so that easy disassembly is afforded in case of leakage or other failure.

A connecting member is provided between an inside environment of a compartment and an environment outside the compartment. The compartment is isolated relative to the outside environment and the compartment comprising a communication orifice defined by a first connector connecting element. The connecting member comprises a main body arranged to cooperate with the communication orifice of the isolated compartment. The main body comprises a second connector or connecting element complementary to the first connecting element of the communication orifice so as to form a tight connection between the first connecting element and the second connecting element, the main body further being crossed through by a tubing comprising a first end on the side of the outside environment and a second end on the side of the inside environment.

Connection module for fuelling a space launch vehicle with cryogenic propellant. The module has a ground part placed on the launch pad mast side of the launch vehicle; a flight part fixed to the launch vehicle; a link fixed to the parts to unite them. The module exhibits a passage crossing the ground part, the flight part and the link. The passage allows communication between a line of the launch pad, such as an umbilical structure of the launch vehicle, and a line supplying a tank or a pneumatic circuit of the launch vehicle. Twisting means, such as a lever or an arm, are linked to a disconnection cable. During lift-off, the twisting means apply a torque to the link which causes the breakage of a link groove, allowing the link to split into two axial portions.

The present invention relates to a marine drilling riser joint, adapted for the securement of one or more umbilicals (36) thereto. The marine drilling riser joint comprises one or more umbilical gutter assemblies (8), connected to or formed integral in an outer surface of a buoyancy module on the exterior of the marine drilling riser joint and provided parallel to the riser pipe, the umbilical gutter assembly comprising: an umbilical gutter (8) adapted to accommodate one or more umbilicals; and a resilient gutter cover (82a, 82b), which is elastically deformable by a loom tool, which resilient gutter cover in a closed position covers the umbilical gutter and in an elastically deformed position provides a working clearance to allow the one or more umbilicals to be introduced into the umbilical gutter.

A connection arrangement for creating a fluid-tight connection of a first pipe arrangement to a second pipe arrangement, wherein the first pipe arrangement and the second pipe arrangement each have at least two channels, comprising a first coupling element allocated to the first pipe arrangement and a second coupling element allocated to the second pipe arrangement, wherein the first coupling element and the second coupling element can be connected to one another by a locking element, wherein the locking element encompasses the channels.
