Subsea PIG & Plug Launcher

The Balltec Subsea PIG & Plug Launcher is the world’s first diverless and flangeless subsea PIG and plug launcher. The tool enables the dewatering of pipelines from a cut section of pipe. The launch system can work independently or in conjunction with the Balltec PipeLOK™ recovery tool.

The Subsea PIG & Plug Launcher can grip and seal onto a cut end of a pipe enabling the launch without the need of any additional fixtures. The PIG & plug launcher uses Balltec’s proven gripping and sealing technology to create a fast, safe and reliable connection.

Designed, built and tested to international standards, the Subsea PIG & Plug Launcher complements other services within Balltec’s pipeline solutions range and can be designed to suit specific client specifications or rented from our fleet where available.
