A high pressure pipe of high density polyethylene material includes an internal lining (3), an intermediate reinforcement layer (2) and an outer cover layer (1). The high density polyethylene material of the internal lining (3) is filled with a filling material (5). As a result, the mixture of high density polyethylene and filling material provides resistance against higher temperatures, allowing the pipe to be able to transport fluids at elevated temperatures.

A method protects a field joint of a pipeline, where chamfered edges of thermally-insulating parent coatings on conjoined pipe lengths are in mutual opposition about a longitudinally-extending gap. The method includes manufacturing an hourglass-shaped inner layer around the pipe lengths, which layer may be moulded. The inner layer extends longitudinally along the gap between the chamfered edges and at least partially overlies the chamfered edges. A thermally-insulating solid insert is assembled from two or more parts to lie in the gap surrounding the inner layer, and pressure is applied radially inwardly from the insert to the inner layer. An outer layer of molten material is manufactured around the insert to form a watertight barrier and to form one or more melted interfaces with the inner layer. Corresponding field joint arrangements are also disclosed.

A fitting assembly includes a fitting and a tube. The fitting has a fitting body having a straight through hole and an attachment or base port, connected to the through hole by a first passageway generally perpendicular to the through hole. The tube has an outer diameter smaller than the through hole allowing a first end of the tube to pass through the through hole. A seal is positioned in one of a circumferential slot in the tube and a circumferential slot in the through hole of the fitting body, the seal sealing a second end of the tube to the fitting body. A cover is sealingly attached to the first end of the through hole. One of the cover and the tube has a portion that extends into an intersection of the through hole and the first passageway, the portion having an aperture that prevents blockage between the attachment or base port and the second end of the through hole.

A method and apparatus are disclosed for at least partially repairing a defect in a tubular composite layer. The apparatus comprises a plurality of independently movable abutment elements (3820) each supported in a spaced apart relationship via a respective one of at least one support member (3810). Each abutment element is associated with a respective drive axis along which the abutment elements are movable and the drive axes of all abutment elements extend outwardly from a common centre point.

A subsea arrangement comprising a first subsea structure, a second subsea structure, and a clamp connector. The first subsea structure is provided with at least one coupling member which is designed to mate with a corresponding coupling member on a first side of the clamp connector so as to allow the clamp connector to be releasably connected and secured to the first subsea structure through these coupling members. The second subsea structure is provided with at least one coupling member which is designed to mate with a corresponding coupling member on an opposite second side of the clamp connector so as to allow the clamp connector to be releasably connected and secured to the second subsea structure through these coupling members.

A method for installing an accessory onto a pipeline to be laid on the seabed, includes launching the pipeline from a first position of a tower in which the tower is at an angle α with respect to the vertical; stopping the launch of the pipeline, and hanging off the launched pipeline in a hang off module; positioning an accessory in a tower firing line; attaching the accessory to the launched pipeline in the hang off module and to at least one A&R cable; suspending the accessory and the launched pipeline from an A&R system; disengaging the hang off module from the launched pipeline; pivoting the pipeline launch tower to an accessory launch position in which the tower is at an angle γ that differs substantially from angle α, such that a pipeline launch trajectory is created which is large enough to launch the accessory and the launched pipeline with the A&R system.

A dunnage bag air valve adapter can be coupled to a dunnage bag air valve to allow a user to inflate the dunnage bag using an inflation tool having an inflation tool head with which the dunnage bag's air valve may be otherwise incompatible.

An insulating insert is positioned around a field joint of a pipeline to insulate the field joint. The insert comprises a longitudinal series of annular or part-annular filler segments of insulating material, curved about a longitudinal axis, that are each joined to one or more adjacent segments of the series by at least one link. The links may be webs, rods or articulated links. The links are flexible relative to the segments to facilitate bending of the insert along its length by enabling relative angular displacement between adjacent segments of the series.

A casing roller apparatus including an actuation apparatus for facilitating operation of the casing roller apparatus and an engagement apparatus for securely engaging a unit of casing to permit an oilfield worker to roll the unit of casing. The casing roller apparatus is used in a method of engaging a unit of casing with the casing roller apparatus and rolling the unit of casing from a first location to a second location.

A double wire lip hook is provided. The double wire lip hook may be used for electrical power line work by helicopter or crane, in which closely spaced pairs of wires are used. The double wire lip hook may also be used for single wires and other lifting and pulling tasks. The example double wire lip hook has a geometry designed for high strength, maintaining a substantial cross-sectional area of metal or alloy throughout its profile. The double wire lip hook provides dual opposing hooks with wide throats cambered for wires. Dual tapers in a vertical shank member provide a large gape opening for each hook and keep loads on either side close to the vertical lifting axis for improved stability. Features such as one or more support ribs add to lifting strength and resistance to yield failure.
