Balltec Subsea PIG Launcher

Balltec’s Subsea PIG Launcher is the world’s first diverless and flangeless subsea PIG Launcher. The PIG launch system can work independently or in conjunction with Balltec’s PipeLOK™ pipeline recovery tools to enabling pipelines to be lifted from the sea bed in a dewatered state.

Balltec’s subsea PIG Launcher can grip and seal onto a cut end of a pipe meaning the PIG can be launched without the need for any additional fixtures to be added onto the pipe. The PIG Launcher uses a combination of Balltec’s gripping & sealing technologies to create a safe and secure connection.

Designed, built and tested to international standards, the Subsea PIG 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.
