Pipeline Bungs have the core properties of a J-Tube Seal, but are simpler in installation given the fact that their core purpose is simply to plug the end of any circular orifice.
Pipeline bungs are used in the following applications:
• Temporary sealing of J-Tubes prior to pull-in operations
• General pipeline isolation
• Pipeline abandonment applications
• Suction pile plugs
• Monopile isolation
Pipeline Bungs come in a variety of forms for installation topside or subsea, using diver or ROV intervention. They can be designed for long or short-term use and implement a host of features such as pressure monitoring ports, messenger wire attachments, test facilities, flooding / flushing capabilities etc.
