Abstract: A plug launching system includes a main body and a plug canister (102) disposed within the main body. The plug canister includes a liner (200), a first rotational assembly (120) disposed about the liner, wherein the first rotational assembly is configured to support a first plug disposed within the liner and selectively enable fluid flow from an annulus between the main body and the plug canister (102) to a central passage of the liner (200), and a second rotational assembly (118) disposed about the liner (200), wherein the second rotational assembly is configured to support a second plug disposed within the liner (200) and selectively enable fluid flow from the annulus between the main body and the plug canister to the central passage of the liner, wherein the first and second rotational assemblies are configured to be actuated independently from one another.
