OFFSHORE PIPELINE INSTALLATION METHOD

摘要

An underwater pipeline is installed by lowering it to the bottom of the water from the stern of a lay barge as the barge advances along a long preassembled pipeline section which floats near the surface of the water and is held in tension by a second vessel positioned in front of the lay barge. An additional floating section is connected in place when the lay barge reaches the end of the initial section, this additional section is held in tension by the second vessel, and laying of the line is continued as the lay barge advances.
