TUBULAR INSTALLATION SYSTEM AND METHOD

摘要

The present invention relates to a tubular installation system for J-laying tubulars comprising a J-lay tower structure, a tubulars supply system and a loader device comprising tubular grippers and a boom for transporting a tubular, an accessory supply system and accessory handling means for transporting an accessory between the essentially horizontal accessory supply position and the firing line. According to the invention, the accessory handling means are distinct from the tubular grippers and are attached to the boom 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.
