Tubular installation system and method

摘要

The present invention relates to a tubular installation system (10) for J-laying tubulars comprising a J-lay tower structure (100), a tubulars supply system and a loader device (20) comprising tubular grippers (21a-c) and a boom (24) for transporting a tubular, an accessory supply system (200, 201, 202) and accessory handling means (29) for transporting an accessory between the essentially horizontal accessory supply position and the firing line. According to the invention, the accessory handling means (29) are distinct from the tubular grippers (21a-c) and are attached to the boom (24) of the loader device, at a different position than the tubular grippers, such that the loader device can be used as desired for transporting a tubular or an accessory between the respective supply position and the firing line.

1. A tubular installation system for J-laying tubulars said system comprising:
a J-lay tower structure for lowering and/or raising a tubular or an accessory along a firing line extending along the J-lay tower structure; a support for supporting the J-lay tower structure; a tubulars supply system for supplying tubulars to an essentially horizontal tubular supply position in the vicinity of the tower, J-lay tower structure; a loader device for transporting a tubular between the essentially horizontal supply position and the firing line, wherein the loader device comprises:
one or more tubular grippers adapted for gripping the tubular;a base; anda boom to which the one or more tubular grippers are attached, said boom being pivotable with respect to the base in a boom pivot direction about a horizontal boom pivot axis, between a lowered position for gripping a tubular in an essentially horizontal tubular supply position, and a raised position for delivering a tubular to the firing line and vice versa; an accessory supply system for supplying an accessory to an essentially horizontal accessory supply position in the vicinity of the J-lay tower structure; and an accessory handling mechanism configured to transport the accessory between the essentially horizontal accessory supply position and the firing line, wherein the accessory handling mechanism is distinct from the one or more tubular grippers and is attached to the boom of the loader device, at a different position than the one or more tubular grippers, such that the loader device can be used as desired for transporting a tubular or an accessory between the respective supply position and the firing line.
