  • Patent number: 6742963
    Abstract: A tool (1′) for pulling an end of a first pipe (102) towards a stationary, second pipe (101) includes gripping devices (47) for holding the first pipe (102), and winch devices (140) for pulling the tool with the pipe towards the stationary pipe (101). A collar (50) which is releasable attached to the stationary pipe, has an anchoring point (60,61) for the pull-in line (141). When the tool with the end of the first pipe approaches the stationary pipe, a moment arm (149) on the tool interfaces with a stop (65,66) on the collar. At the same time, an alignment and stroking actuator (110) grips the collar above the axis of the stationary pipe. The moment arm and alignment actuator cooperate to raise the first pipe into a horizontal position so that it is aligned with the stationary pipe.

  • Publication number: 20030049076
    Abstract: A tool (1) for pulling an end (102) of a first pipe towards a stationary second pipe (100). The tool comprises gripping devices (46, 47) for securing the second pipe and winch devices (40) for pulling the tool with the pipe end towards the fixed point. A collar (50) which is attached to the stationary pipe (100) provides an anchoring point for the pull-in line. When locating the first pipe (102) directly on the stationary pipe (100), the collar (50) is advantageously equipped with an adaptor (70; 170), which comprises means for releasable attachment to the first pipe (102).
