Abstract

A plug release system includes a tubular member having an outer surface and an inner surface defining a flow bore having a central longitudinal axis. A sleeve is positioned in the flow bore. The sleeve includes a first end having a radially outwardly extending annular lip, and a second end. A release mechanism is rotatably mounted in the tubular member radially offset from the central longitudinal axis. The release mechanism includes a sleeve support surface that selectively engages the radially extending annular lip. The release mechanism is rotatable between a first position wherein the sleeve maintains a plug in a retained configuration and a second position, wherein the sleeve releases the plug into the tubular member.
