Abstract
As shown a carrier module () includes a magazine () having five chambers () each adapted to receive a pipeline pig, rotatably mounted on a blind hub () attached to a frame (). A hanging eyeallows the module to be lowered to an undersea location where, guided by a ROV via a grab handle, its frame member () is received by guides () of a launcher module (). The magazine passes through a large connector () which engages the blind hub. The ROV operates a bucket drive () causing the connector to engage the blind hub in sealing fashion thus enclosing the magazine in a launch chamber (). A hydraulic ram () indexes the magazine to select a chamber from which a pig is to be launched or an empty chamber to receive a pig. Indexing is achieved by a roller on the free end of the ram shaft engaging in a cusped track () on the magazine. A pressure connection () for launching fluid goes through the center of the magazine, through the blind hub and back into a selected chamber.
