Temporary Line Plugging can be achieved using the DNV GL type approved BISEP®. STATS patented BISEP provides fail-safe double block and bleed isolation deployed through a single full bore hot tap penetration, without the need for additional bleed or vent ports. The BISEP offers significant safety advantages over traditional line stop technology, the hydraulically activated dual seals provide leak-tight isolation of live, pressurised pipelines.

The development of the BISEP with integrated bypass provides dual seal isolation and bypass through a single hot tap fitting, offering operators significant cost and time savings.
