Abstract: A method of manufacturing a vent for a pipeline liner comprises overmoulding a porous element in a polymer body. This produces a vent in which the element extends across, and is in fluid communication with, a through-passage formed in the body during overmoulding. The element is supported in a mould cavity clamped between opposed internal mould formations that define at least part of the through-passage. The integrity of the vent and of the interface between the vent and the liner is maintained during die-drawing of the liner. Thus, the porous element is mechanically engaged with the surrounding body as flowable material of the body is absorbed into the element during overmoulding. Internal flanges also restrain the element against movement along the through-passage. The vent is also fused with the liner by heating interface regions to a softening or melting temperature before inserting the vent into a wall of the liner.

Abstract: A structure such as a pipeline bundle is pulled into or through shallow water, for example when launching the structure, by applying a tensile pulling force to the structure through rigging that extends to the structure from a winch of a first vessel. The pulling force is at least partially reacted through a pennant line that extends from the first vessel to a second vessel and that hangs between the first and second vessels to engage the seabed soil frictionally. The vessels may also self-propel to contribute their thrust to the pulling force. The pennant line includes a clump weight such as a bundle of chains that can be repositioned easily for additional pulls by being lifted between the vessels before being lowered to the seabed at a new location.

Abstract: A method of launching an elongate subsea structure such as a pipeline bundle unit into water comprises providing buoyant support to the structure by displacing water with a hollow buoyancy unit that applies buoyant upthrust to the structure. By lowering the buoyancy unit in the water to bring a permanently open aperture of the buoyancy unit beneath a surface level of the water, the buoyancy unit is flooded with water through the or each permanently open aperture to reduce the buoyant upthrust applied to the structure.

Abstract: An auxiliary control system and method for controlling subsea equipment such as a tree or manifold, for example in the event of failure of a control umbilical. A power unit is installed subsea and then a control tool is coupled to the subsea equipment. Control signals from a topside source are transmitted to the power unit, which powers and controls the control tool in response to the control signals to operate a control element of the subsea equipment, such as a valve.

Abstract: A pipe-bending rig comprises an anchorage for holding a proximal end of a pipe and a bending former that presents a convex forming surface toward a side of a pipe when the pipe is held by the anchorage to extend distally from the anchorage. A pipe- bending drive exerts lateral force on the pipe to deflect a distal end of the pipe, which effects plastic bending of the pipe along its length against the forming surface. A carriage is movable along a path with respect to the anchorage and the bending former during deflection of the distal end of the pipe. A link carried by the carriage applies distal force to the pipe to impart longitudinal tension to the pipe as the pipe is being bent against the forming surface.

Abstract: A towable pipeline bundle (12) for installation underwater at a subsea oil or gas production site comprises two or more bundled elongate elements (34, 36), at least one of which is a flowline for carrying production fluid along the bundle. A rigid buoyancy pipe (34) of polymer-composite material extends along and supports the bundled elongate elements. The buoyancy pipe has an internal buoyancy chamber and at least one port for introducing fluid into the buoyancy chamber. The buoyancy pipe (34) is arranged to have positive buoyancy in seawater when its buoyancy chamber contains a fluid less dense than seawater. In this way, the buoyancy pipe (34) confers substantially neutral buoyancy on a towable unit comprising the bundle (12). The unit can then be towed in mid-water to the production site and lowered there onto the seabed.

Abstract: A method of coating a field joint (34) of a pipeline comprises: placing at least one body (66) comprising a thermoplastics material around the field joint; heating the body (66) in a mould cavity (44) around the field joint (34) to effect thermal expansion of the thermoplastics material; and constraining thermal expansion of the body in the mould cavity to apply elevated pressure between the body and pipe sections joined at the field joint (34). The elevated pressure improves bonding and fusing between the body, which forms a field joint coating, and the parent coatings and the exposed pipe sections of the pipe joints. The body need not be fully molten, which reduces the mould residence time including in- mould heating and cooling phases.

Abstract: An inspection, monitoring, maintenance or construction task is performed on a subsea structure by using an underwater vehicle to carry a submersible package (24) to the subsea structure. The package comprises a tool or sensor arranged to perform the required task on the subsea structure, and an on-board power unit and controller arranged to power and control the tool or sensor. The package is transferred from the underwater vehicle (10) to be supported by the subsea structure. The underwater vehicle can then stand off from the package. While the package is supported by the subsea structure, the tool or sensor of the package performs the required task on the subsea structure, powered and controlled by the on-board power unit and controller of the package.

Abstract: To avoid using an expensive, heavy pipeline end termination (PLET) (1c) on a rigid pipe section (1) on the seabed to perform an underwater connection of that pipe section to a flexible pipe section (34), a rigid-to-flexible connector (RFC) (1b) is provided on the rigid pipe section (1) instead of a PLET and the pipe end having the RFC (1b) is raised to the surface (107) of the sea, while leaving a portion of the rigid pipe section on the seabed (400). The RFC is then connected to one end of the flexible pipe section (34), and the latter lowered to the seabed with the raised end of the rigid pipe section (1) attached, to return the rigid pipe section (1) to the seabed (400). Since the RFC (1b) on the rigid pipe section (1) is connected to the flexible pipe section (34) at the surface of the sea, the RFC can have a simpler, lighter, technical design, resulting in significant cost, manufacturing time and quality control time savings.
Abstract translation: 为了避免在海床上的刚性管部分（1）上使用昂贵的，重的管道末端（PLET）（1c），以将该管段水下连接到柔性管段（34），将刚性 - 柔性连接器（RFC）（1b）设置在刚性管部分（1）上而不是PLET，并且具有RFC（1b）的管端被升高到海的表面（107），同时留下一部分 海底刚性管段（400）。 然后将RFC连接到柔性管段（34）的一端，并将后者连接到刚性管段（1）的升高端部上升到海底，将刚性管段（1）返回到海底 （400）。 由于刚性管段（1）上的RFC（1b）连接到海面上的柔性管段（34），RFC可以具有更简单，更轻的技术设计，导致显着的成本，制造时间 并节省了质量控制时间。
