Abstract A flange catching, aligning and closing tool 10 designed to facilitate the tie in of spools and other similar mechanical assemblies that utilise a bolted 5 flange for installation, for example, in subsea pipelines. The tool 10 has an elongate support member 12 having a locating pin 14 mounted adjacent one end with its longitudinal axis 16 substantially parallel to a longitudinal axis 18 of the support member 12. A slide assembly 20 is slidably mounted on the support member 12 and has a movable drift pin 22 provided in 10 connection therewith. In use, when the locating pin 14 is located in a bolt hole on a first flange, a second flange can be brought into partial alignment with the first flange by engaging with the support member 12, and the drift pin 22 can be inserted in a matching bolt hole in the second flange to bring the two flanges into full alignment.
