Abstract

A compact subsea pig launcher comprises a tubular magazine for holding a plurality of pipeline pigs in longitudinal succession ready for launching successively into a subsea pipeline. The magazine is shaped to define at least one turn such as a coil around an upright axis. Thus, a series of pigs are stored in longitudinal succession along a path that is curved in plan view around the upright axis. During launching, at least one of the series of pigs is advanced along the path with angular movement around the upright axis.
