A pipe pulling technique where an adaptor is attached to the end of the pipe prior to the pipe being pulled underground, for example through a drilled hole. Attaching the adaptor to the pipe end prior to the pipe being pulled underground is faster and reduces danger to workers compared to the conventional process of attaching the adaptor to the end of the pipe after the pipe has been pulled underground.

A curl-forming apparatus (1) includes: a main body (20) configured to deform a profile strip (100); and a support body (3) configured to support the main body (20) in a holding unit (4) for the profile strip (100). The profile strip (100) is helically wound on an inside of the holding unit (4). The main body (20) is disposed in a hollow part of the holding unit (4) and is configured to draw and deform the profile strip (100) inside the holding unit (4). The support body (3) is rotatabe relative to the holding unit (4), and is configured to rotate about an axis of the holding unit (4) in synchronization with the main body (20) that draws the profile strip (100).

A winding machine (1) includes a main body (20), a first arm (40), and a second arm (50). The main body (20) moves toward a winding direction front side as a profile strip (100) is added, while rotating at a winding direction front end portion of a formed pipe member (4). The first and the second arms (40) and (50) are supported by the main body (20) respectively at positions away from each other in a circumference direction of the formed pipe member (4), and extend toward a winding direction rear side between an existing pipe (2) and the formed pipe member (4). The first arm (40) includes a first restricting portion (43) that comes into contact with a winding direction front side of a reinforcement member (120) provided to the profile strip (100) forming the formed pipe member (4) via the profile strip (100). The second arm (50) includes a second restricting portion (52) that comes into contact with a side of the reinforcement member (120) provided to the profile strip (100) forming the formed pipe member (4) opposite to the side to be in contact with the first restricting portion (43), via the profile strip (100).

A towable unit for subsea processing of well fluids comprises a pipeline bundle extending between, and capable of acting in tension between, a first towhead at an upstream end of the bundle and a second towhead at a downstream end of the bundle. At least one of the towheads has an on-board processing facility for processing the well fluids, which facility effects at least separation of water phases that are present in the well fluids.

A pipe support structure comprised of a series of blocks mounted on a base to create opposing ridges arrayed on opposite sides of a central drainage channel. The ridges have a rounded curved outer surface and create intervening valleys that are sloped to direct fluid flow into the central drainage channel. The ridges are arranged and oriented so that the curved outer surface of the ridges support the pipe on its peripheral underside above with the drainage channel and create a space between the bottom of the pipe and the base. The blocks may be angled to further facilitate desired drainage into the drainage channel.

Example air duct assemblies include a pliable air duct supported such that the duct is maintained in a generally expanded shape even when the duct is deflated. In some examples, a series of hangers suspend the duct from one or more cables, tracks or other type of overhead support. The hangers are spaced apart and distributed over the length of the duct, and each one contributes in pulling the duct taut in the duct's longitudinal direction.

A marine pipeline installation vessel for laying a pipeline on the seabed, the vessel at least being adapted to carry out the reel lay method, wherein the vessel includes at least a first and a second storage reel for storage of the pipeline to be laid, which storage reels are positioned in or onto the vessel; a pipeline launch tower mounted to the vessel, which pipeline launch tower is adapted to launch the pipeline in a firing line along said tower; a pipeline guide which is mounted at an elevated position to the pipeline launch tower, which pipeline guide has a pipeline guide surface member providing an essentially circular or semi-circular pipeline guide surface, which pipeline guide is adapted toin a primary pipelaying position thereof relative to the tower guide a pipeline from a first storage reel over the pipeline guide into the firing line, wherein the pipeline contacts the pipeline guide surface at a first contact point fore of the firing line and departs the surface at a first departure point into the firing line.
