Abstract: A pipe assembly (10) includes a composite pipe (12) having a composite material formed of at least a matrix material and a plurality of reinforcing elements embedded within the matrix material. The pipe assembly (10) further comprises a metallic pipe stub (14) secured to an end region of the composite pipe (12) and configured to support a connector (20) to permit the pipe assembly (10) to be secured to separate infrastructure.

Abstract: A tubular comprises a composite material including a matrix and a plurality of reinforcing elements embedded within the matrix. A method for heating the composite material of the tubular comprises exposing the composite material to a time-varying magnetic field to directly induce a flow of electrical current in the composite material. The method may comprise configuring the composite material so as to control the flow of electrical current and/or heat in the composite material. The method may be used for heating a composite fluid conduit for use in a subsea environment for the removal of the build-up of wax and/or hydrates on an inner surface of the fluid conduit. Additionally or alternatively, the method may be used for deforming a composite fluid conduit, or for joining a composite fluid conduit to a further component such as a further composite fluid conduit.

Abstract: A subsea conduit system comprises a conduit extending between a surface vessel and a subsea support, and a load arrangement connected between a subsea anchor and the conduit at a region of connection which is intermediate the vessel and the subsea support to apply a force on the conduit. The conduit is configured such that the applied force generates axial tension in the conduit between the region of connection and the vessel, and between the region of connection and the subsea support.

Abstract: A hybrid riser system comprises a lower riser section secured between a lower subsea anchor and an upper buoyant structure, and an upper riser section extending between the lower riser section and a surface or near surface vessel. The lower riser section comprises an elongate support and one or more composite fluid conduits secured to and extending adjacent the elongate support. The composite fluid conduits comprise a composite material formed of at least a matrix and one or more reinforcing elements embedded within the matrix. The upper riser section comprises one or more flexible conduits in fluid communication with the composite fluid conduits.

Abstract: An apparatus (10) for providing fluid communication between first and second connection points (34,38) comprises a deformable pipe assembly (12) including a composite material. A first connector (34) is mounted at one end of the deformable pipe assembly and is configured for connection with a first connection point and a second connector (38) is mounted at an opposite end of the deformable pipe assembly and is configured for connection with a second connection point. An adjusting assembly (44) is configured to apply a force between separated regions of the deformable pipe assembly, such that deformation of the deformable pipeline assembly is responsive to the adjusting assembly to permit a relative separation of the first and second connectors to be adjusted.

Abstract: A golf swing instructional device for training a golfer comprises an attachment portion having a first portion adapted to be positioned at the shaft of a golf club and a second portion adapted to be connected to two guide supporting elements. The first and second supporting elements have each a contact surface to be in contact with one or the other forearm of the practicing golfer. The two supporting elements are extending from the club contacting portion, wherein the first portion comprises a reception to accommodate the shaft of a golf club and fixation means to fix the first portion around the shaft of the club. The two guide supporting elements each comprise a first straight portion, a second straight portion and a bent connecting portion in-between.

Abstract: A metal pipe 10 is joined to another metal component 12 by shrinking the outer component onto the external circumference of the pipe. The internal diameter b of the outer component is initially smaller than the external diameter a of the pipe, but the outer component is heated so that it expands to a diameter at which it will fit over the pipe. When the outer component is fitted over the pipe and the temperature of the outer component allowed to drop, it will contract onto the surface of the pipe to make a permanent strong joint between the two parts.

Abstract: A known deepwater solution for production risers for extracting oil and gas is the SLOR™ riser. The design of the SLOR™ riser is not compatible with large numbers of risers and thus there is a need for a deep water riser that can be deployed in large numbers, for example 20 to 30 risers. The present invention discloses a support frame that can be used to receive a plurality of risers, which can then be connected to a surface vessel.

Abstract: A fluid operated tool 30 (FIG. 4) for use in replacing a body clamped between facing platens has an open ended tubular member 31, through which the body can pass, that carries outwardly thereof, and axially extending, coplaner support arms 33, 34 at the end of which are hydraulic piston and cylinder arrangements 35, 36 for inserting between the platens to overcome the clamping force on the body, permitting it to be removed and replaced by way of the tubular member 31. The tool may be used subsea with a submersible to handle it and provide hydraulic power.
