Abstract
Connecting a tubular string to a subsea installation. The tubular string includes a short first section and a longer second section. The length of the first section is approximately one-half the depth between the lowermost guide ring of a fixed platform and the top of the subsea installation. One end of the first section is provided with a connector and the other end with a connector and a funnel. The first section is lowered through the guide rings and connected to the subsea installation. One end of the second section is provided with a connector and the second section is lowered through the guide rings and into the funnel. Since the two adjacent ends are about midway between the subsea installation and the lowermost guide ring, the adjacent ends are easily bent into alignment by the camming action resulting when the end of the second section slides along the inside tapered surface of the funnel when the axes of the platform and subsea installation are offset.
