Abstract
A plug (10) is disclosed which is clamped to the end of a first pipeline section (14) being worked on by a line travel device (12). The line travel device (12) can completely perform its operation on the first pipeline section and move on to the plug. The plug is then unclamped from the first pipeline section and the plug and line travel device are moved together to the second pipeline section (16) to be worked on. The plug is clamped to the second pipeline section (16) to be worked on and the line travel device moves off the plug onto the second pipeline section to perform its operation on the entire length of the section.
