Techniques for implementing a pipe segment that includes a tubing inner barrier layer that defines a pipe bore through the pipe segment, a venting tubing annulus implemented around the tubing inner barrier layer, in which the venting tubing annulus includes a first solid material implemented to define a venting fluid conduit, a tubing intermediate barrier layer implemented around the venting tubing annulus, a reinforcement tubing annulus implemented around the tubing intermediate barrier layer, and a tubing outer barrier layer implemented around the reinforcement tubing annulus. The reinforcement tubing annulus includes a second solid material that is different from the first solid material and is implemented to define a reinforcement fluid conduit. Additionally, the venting fluid conduit facilitates venting fluid that permeates from the pipe bore through the tubing inner barrier layer out from the pipe segment before the fluid contacts the second solid material in the reinforcement tubing annulus.

The invention concerns a subsea umbilical comprising an electrical conductor (2) and/or a fluid pipe, and an outer sheath (7) surrounding the electrical conductor (2) and/or the fluid pipe. The umbilical (1, 20, 21, 25, 30, 40, 51, 60) further comprising a plurality of deformable rods (3a, 3b, 15, 23a, 23b, 26a, 27a, 26b) evenly distributed between the electrical conductor (2) and/or the fluid pipe, and the outer sheath (7) for radial load protection of said electrical conductor (2) or fluid pipe.

Multi-hose arrangement (1) having an outer hose (2) and at least one inner hose (3, 3a) disposed in the outer hose (2), and at least one coupling end (4) to which the outer hose (2) and the at least one inner hose (3, 3a) are attached. The the at least one coupling end (4) has a flow opening (5) for the outer hose (2), in which flow opening (5) is disposed a receptacle (6) for the at least one inner hose (3, 3a), and this receptacle encompasses the at least one inner hose (3, 3a) on less than a full circumference of the at least one inner hose (3, 3a).

Techniques for implementing and/or operating a system that includes a pipe fitting to be secured to a pipe segment and a swage machine. The pipe fitting includes a fitting jacket to be conformally deformed around tubing of the pipe segment. The swage machine includes a grab plate that interlocks with the pipe fitting, a die plate, in which a die is to be loaded in the die plate, a swaging actuator secured to the die plate, in which the swaging actuator facilitates conformally deforming the fitting jacket around the tubing of the pipe segment by causing the die plate and the grab plate of the swage machine to move toward one another, and a die retainer actuator secured to the grab plate of the swage machine, in which the die retainer actuator extends through the grab plate toward the die plate and pushes against the die.

A vent arrangement for a flexible pipe body. The vent arrangement comprises a vent valve and an annular region flushing valve. The vent valve is arranged to couple to an annular region access port of a flexible pipe end fitting such that the vent valve can vent fluid from the pipe body annular region. The annular region flushing valve is in fluid communication with the vent valve and the annular region access port. The annular region flushing valve is arranged to inject fluid into the vent arrangement for flushing the vent valve, the annular region access port or the pipe body annular region. An end fitting incorporating the vent arrangement, a flexible pipe comprising the end fitting and a flexible pipe body coupled to the end fitting, and a method of manufacturing a flexible pipe are also disclosed.

Embodiments of an alloy that can be resistant to cracking. In some embodiments, the alloy can be advantageous for use as a hardfacing alloys, in both a diluted and undiluted state. Certain microstructural, thermodynamic, and performance criteria can be met by embodiments of the alloys that may make them advantageous for hardfacing.

A tubing assembly is provided that can comprise a plurality of tubes or lumens that can be disposed within a head of a peristaltic pump. The tubing assembly can provide a flow rate or volume capacity that is generally equal to or greater than that achieved with a comparable prior art tube while operating at higher pressures than that possible using the prior art tube. Further, in accordance with some embodiments, the tubing assembly can achieve a longer working life than a comparable prior art tube, and the load on the pump motor can be reduced such that the pump life is increased and/or a larger pump motor is not required to achieve such advantageous results.
