Subsea Temporary Launcher / Receiver
Flangeless subsea launchers / receivers can be attached to any open pipe end without the need for hyperbaric welding. Quick and efficient installation enables maintenance pigs or isolation plugs to be deployed and recovered during pipeline maintenance or repair activities.
Currently subsea launchers are designed for flanged pipe connection, however, flanged connections limit the location of where a subsea launcher can be attached. The Flangeless Subsea Launcher can be efficiently lowered to the seabed and introduced to any open pipe end without the need for a flanged connection or hyperbaric welding to install a flange at the desired location.

The launcher housing incorporates a lock and seal module which when actuated provides a secure connection to, and seal against, the outside diameter of the pipe using STATS proven lock and seal technology. Once actuated, the locks prevent movement of the pipe during pigging operations and the seal provides a leak-tight barrier.
Flangeless Subsea Launcher and Remote Tecno Plugs® can be utilised as part of a contingency to enable pipeline flood prevention and wet buckle recovery solutions during pipe laying operations.
