BISEP DS with Integrated Bypass

Pipeline owners and operators are constantly looking to improve operational safety and reduce time and costs during pipeline repair and maintenance activities. STATS BISEP developed more than a decade ago, is the true industry-first, leak-tight double block and bleed isolation technology. The BISEP is the market leading technology solution for temporary line plugging, offering a leak-tight seal, every time at any pipeline pressure. The BISEP offers significant safety advantages over traditional line stop technologies with seals that can be proven, tested and monitored before breaking containment. Deployed through a single hot tap intervention, the BISEP reduces costs and results in faster job completion.

The dual seal isolation barrier is confirmed once each seal is independently tested with full pipeline pressure - and the pressure between the seals is vented, creating a zero-energy zone. Following successful testing of both seals the zero-energy zone is monitored confirming the isolation integrity throughout the workscope - with zero leakage.

Hydraulically activated elastomer seals provide leak-tight isolation in ambient to high pressure pipelines. The hydraulically set seals provide a fail-safe isolation with pipeline pressure maintaining isolation integrity independent of hydraulic activation. In addition, two independent hydraulic systems maintain seal activation for increased safety.

With an extensive global track record, covering 3” to 56” and pressures from ambient up to 2220 psi, there is no limit to the application of the BISEP. Whether your pipeline is located on an offshore platform, onshore or subsea the BISEP is covered by DNV Type Approval that meets the requirement for pipeline isolation plugs.
