Celeros offers patented Pig Stop and Bypass solution


The patented Pig Stop and Bypass (PSB) mechanism from Celeros Flow Technology allows automated pigging on oil and gas pipelines to be managed remotely and reliably, either from land or a main platform.

Enabling complete automation of pig launch processes, the PSB mechanism can reduce platform footprint and realise cost savings through reduced manpower.

Developed by GD Engineering (originators of the Bandlock closure), the PSB mechanism is a critical component of unmanned or normally unmanned platform pigging solutions.

It is designed to be integrated with an automated multiple pig launcher vessel and allows multiple pigs to be preloaded and sequentially launched without the need to depressurise the vessel between pigging runs. The PSB therefore delivers benefits that include reduced maintenance time and costs, as well as improving safety in oil and gas operations.

The PSB mechanism is proven in the field as a reliable and safe system for ensuring that individual pigs are positively launched into a pipeline, using a sophisticated bypass and pressure balance system.

It allows interchangeability of any type of conventional pig with the same dimensions as the original pig design, as well as allowing future change-out of conventional pigs with intelligent pigs. This gives specifiers and platform operators the advantage of flexibility and a system that is future-proofed.
