Abstract: An internal line-up clamp (20), for aligning two pipes to be welded together, includes a hi-lo measurement system, for example includes a laser source (24) and camera system (22), mounted on the internal line-up clamp (20) and arranged to make a hi-lo measurement (d), indicative of the degree of alignment of the pipes (10a, 10b). The measurement may be made when two pipes are clamped together by means the internal line-up clamp (20). The pipes may then be welded together, whilst the pipes remain clamped together in the same position, and whilst the hi-lo measurement system remains inside the pipes.

Abstract: The free ends of two pipelines lying on the sea bed are joined by raising both ends to above the surface and supporting them on a barge, bringing them into axial alignment and welding them together by inserting a spool piece if necessary. The welded line is then lowered back to the sea bed and the barge moved sideways.

Abstract: A catamaran, adapted for use in laying a submerged pipeline, is provided with a slidable support for the pipeline, including a slightly inclined ramp integral with the awning deck of the catamaran for carrying out the operations for building the pipeline, a moveable stinger extending from the rear end of the catamaran, and an intermediate pipeline supporting element having its bow end hinged to the stern end of the ramp and its stern end pivotally hooked to the front end of the stinger. The stern end of the intermediate pipeline supporting element may be raised or lowered so that its angle of inclination may be varied and it may be locked in position at a selected angle of inclination through a castle-shaped member located abaft the catamaran and including two side frames fixed to the awning deck of the catamaran so that they straddle the intermediate pipeline supporting element and their lower ends are submerged. The frames are provided with vertically spaced pairs of opposed holes for the reception of check pins extending through holes located in the sides of the intermediate pipeline supporting element at its stern end.

Abstract: An arrangement of an umbilical of data communication lines and/or electrical energy transmission lines is mounted on a lazy wave catenary riser. The umbilical has a first section extending from an upper hang off location of the riser continuously downward to a first installation point at the riser and a second section extending from a second installation point at the riser continuously downward to the sea bed at a riser touch down location. The first installation point is positioned in an installation region of the riser between a lowest sag bend point and a highest hog bend point of the lazy wave catenary riser extension. The first 1 section is tensioned to a flatter catenary shape than a catenary shape of the riser between the upper hang off location and the first installation point, so that a portion of the first section extends detached from the riser.
