Embodiment Construction

[0057] figure 1 An offshore pipelaying system according to an embodiment of the invention is shown, comprising a vessel VE having a hull HU, an upper deck UD and a pipe installation system for J-shaped pipelay.

[0058] The vessel may be of monohull design, but may also be of other designs (eg, as a semi-submersible, as a converted drilling rig, etc.).

[0059] The pipe installation system includes a J-lay tower structure JT for lowering and raising pipes and fittings in a work line FL extending along the J-lay tower structure JT. The work line FL is substantially vertical and parallel to the J-lay tower structure JT. Preferably, the work line is located adjacent to the J-lay tower structure. The J-laid tower structure may also be referred to as a tower structure or tower in this specification.

[0060] The tower structure JT is supported by the upper deck UD, whereby the upper deck UD acts as a bracing means for supporting the tower JT. Where the upper deck UD supports th...

Abstract

The present invention relates to a pipe installation system comprising: a) a J-lay tower structure (JT) for lowering and raising pipes or fittings along a work line (FL); b) a pipe supply system; c) fittings supply system; d) a loading system configured for transporting pipes and fittings between a horizontal pipe supply location and a production line, wherein said loading system comprises a loading device (LD), an alignment device (LUT), said loading The device comprises a base (BA) and a boom (BO) pivotable relative to the base between a lowered position and a raised position for clamping a horizontally located accessory supply position pipes and fittings on the loader, and the elevated position for subsequent transfer to the line; wherein the alignment unit (LUT) is configured to exchange pipes and fittings with the loading unit and to transport the pipes between the loading unit and the line .

Description

technical field [0001] The present invention relates to a pipe installation system for J-shaped pipe laying, an offshore pipe laying system and a method of handling pipes or fittings. Background technique [0002] A pipe installation system for J-shaped pipe laying is known from the applicant's International Patent Publication WO 2012 / 091560. In WO2012 / 091560, a pipe installation system comprising a J-lay tower structure, a support device for supporting the J-lay tower structure, a pipe supply system and a fitting supply system is disclosed, said J-lay tower structure being used along a service line extending along the tower structure for lowering and / or raising pipes or fittings; the pipe supply system for supplying pipe to a substantially horizontal pipe supply location adjacent the tower structure; and the A fitting supply system is for supplying fittings to a substantially horizontal fitting supply location adjacent the tower structure. [0003] For transporting the pi...
