摘要： A support element (12) for supporting a rigid pipeline (10) during plastic bending of the pipeline has a transverse cross-sectional configuration such that, in use, a pipeline supported by the support element contacts said support element at at least first and second points (14, 16) disposed substantially symmetrically on either side of the plane of bending, the points of contact being arranged such that resultant forces between the pipeline and the support element act at points which are disposed substantially symmetrically about the plane of bending and which are spaced apart by an angle a greater than 90 DEG and less than 180 DEG around the cross-sectional circumference of the pipeline. The angle a is selected so as to minimise ovalisation for a pipeline of given material, diameter and wall thickness, and for a given bend radius and pipeline tension, or to provide useful modification of ovalisation over ranges of these parameters. For most practical applications, the optimal angle a will be greater than 90 DEG and less than or equal to 150 DEG . In preferred embodiments of the invention, the angle a is greater than 90 DEG and less than or equal to 110 DEG .

摘要： Improvements relating to apparatus for diverting a pipeline or other elongate member about an arcuate path, most particularly for diverting a rigid pipeline (300) from a horizontal assembly axis to a desired launch angle from a marine pipelaying vessel (44), including the following: the use of a helicoidal arcuate pipeline path enabling the pipeline (300) to cross itself prior to launch; the use of multiple caterpillar-type roller track assemblies (302) to define the arcuate pipeline path; a method of initiating pipelaying operations by attaching a pre-bent length of pipe (314) to the leading end of the pipeline (300) and pulling the pipeline around the arcuate path by means of an initiation cable (312) attached to the leading end of the pre-bent pipe, and removing the initiation cable (312) and pre-bent pipe (314) prior to commencing pipelay operations; a method of interrupting pipelay operations by displacing the pipeline (300) radially outwardly from its arcuate path, whereafter the pipeline may be clamped and cut, allowing an abandonment and recovery (A & R) cable (322) to be passed around the arcuate path for A & R operations; the apparatus allows pipeline (300) to be plastically bent in a substantially vertical plane to divert the pipeline from its initial, horizontal orientation to a variable launch angle of up to 90 DEG , and is suited for use on marine pipelaying vessels (44) which are also described.

摘要： Methods and apparatus for laying marine pipelines of the type in which the pipeline is assembled along a horizontal axis on board a pipelaying vessel prior to being launched therefrom; in which the pipeline is plastically bent to a desired launch angle and, in most cases, at least partially straightened thereafter. In preferred embodiments, the pipeline is bent through an angle greater than 90 DEG . In the most preferred embodiments, the pipeline is diverted through an angle of substantially 270 DEG , plus or minus an angle allowing variation in the launch angle from the vertical, and crosses itself prior to entering the water. The pipeline (102) is diverted by being passed around a wheel-like diverter structure (104), the pipeline being assembled in multiple fabrication lines to produce stalks which are aligned and connected in a central firing line prior to being fed around the diverter structure. Other variations are also described.

摘要： A reel-type marine pipelaying vessel having a main pipe storage reel (26) mounted for rotation about a vertical axis, and a pipeline diverter structure (30) around which the pipe (28) is bent to a required launch angle as it is unspooled from the reel. The pipe is launched over the side of the vessel, so as to reduce pitching movements transferred to the pipe from the vessel, as compared with conventional stern-launching vessels. The vessel may also include an additional reel (31) for storing flexible pipe (32), which may be launched via the same diverter structure as pipe from the main reel.

摘要： Methods and apparatus for marine pipelaying operations are described in which the pipe to be laid is fed from a storage reel (18), over a bending shoe (20) mounted on a derrick structure (12) located above a moonpool (14), through a straightening assembly (22) suspended from the derrick structure (12) and into the water via said moonpool (14). The pipeline is straightened by being fed piecewise from the reel and being clamped while the straightener assembly is drawn upwards along a length thereof extending between the bending shoe and the moonpool. The system described is suited to use on a drill ship which can be temporarily converted for pipelaying purposes.

摘要： A bi-metal lined pipe and methods of forming such a pipe suitable for spooling onto a reel for marine pipelaying applications, the pipe comprising a carbon steel outer pipe and a liner of corrosion resistant metal, in which the liner is secured along its length to the inner surface of the outer pipe by circumferential fixing means having a circumferential shear strength greater than the circumferential shear stress which would be induced by bending the pipe to a predetermined minimum radius of curvature. The circumferential fixing means securing the liner to the outer pipe includes at least one of the following: adhesive agents selected to provide a circumferential shear strength greater than the circumferential shear stress which will be induced by bending a given combination of outer pipe and liner to a predetermined minimum radius; soldering, brazing or other similar technique to produce a mechanically acceptable bond between the liner and the outer pipe without fusing the bulk material; mechanical interlocking of the liner and outer pipe; solid-phase welding, such as electrical resistance spot welding from the interior of the liner. The circumferential fixing means may be used in combination with known friction-bonding techniques.

摘要： Methods and apparatus for controlling the ovality of rigid, tubular members, particularly pipelines in marine pipelaying operations, most particularly in marine pipelaying operations of the type in which the pipeline is subject to plastic deformation. The pipeline is passed through a guide defining a gap dimensioned to apply a compressive force to the pipeline in at least one direction if the diameter of the pipeline in said direction exceeds the width of the gap. The guide may comprise one or more pairs of rollers (40) disposed on either side of the pipeline path, or a flange (52) on one side of the pipeline path and one or more pinch rollers (50) on the other side of the pipeline path. The apparatus may include sensing devices (68) for measuring the ovality of the pipe and automatic control apparatus for varying the dimensions and/or orientation of the guide in response thereto.

摘要： Method and apparatus for preventing the buckling of a pipeline (10) on either side of a localised zone of increased stiffness in the pipeline (such as a buckle arrester (12)) when the pipeline is bent around an arcuate path, in which packing elements (14) are located between the pipeline and a pipeline bearing surface (20) defining the arcuate pipeline path on either side of the zone of increased stiffness so as to vary the radius of curvature of the pipeline between a first, greatest value adjacent the zone of increased stiffness, and a second smaller value substantially equal to the radius of curvature of the arcuate pipeline path at a predetermined distance from the zone of increased stiffness on either side thereof. The packing elements (14) comprise a graded series of blocks adapted to be attached to the pipeline on either side of the zone of increased thickness. The blocks may be shaped as required to cooperate with the pipeline and the pipeline bearing surface.
