Pig launchers and pig receivers are installed in pipelines to launch and receive pigs, spheres and inspection tools for pipeline maintenance. Our pig launchers and receivers are suitable for onshore, offshore and subsea pipelines.
Pig launchers & receivers offer a safe and effective means of inserting and removing pipeline pigs to and from pipelines. At Halvorsen, we fabricate launchers and receivers to meet specific requirements for each pipeline.
Our in-house design, engineering, fabrication and testing capabilities produce all types of pig and sphere launching and receiving systems. All units are designed and fabricated using relevant codes for pipeline and vessel design.
Sequential launching of pigs
We also design multiple pig launchers to allow the sequential launching of pigs and spheres.
Using our automatic multiple pig launching system, a series of pigs are launched into a pipeline without having to repeatedly depressurize and re-pressurize after each pig launch. The process can be controlled from a remote location. This is particularly relevant on unmanned platforms such as offshore platforms and sour service applications.
