Hot Tapping and 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, pressurized pipelines. Available in sizes 3" to 48" for pressures up to 2200 psi.
STATS BISEPs™ are fully certified by DNV GL to verify that the design criteria satisfies the requirements for Pipeline Isolation Plugs to provide dual seal and isolation in accordance with Offshore Standards; DNV-OS-F101 (Submarine Pipeline Systems) and recommended Practices; DNV-RP-F113 (Subsea Pipeline Repair) and in compliance with the following code; ASME BPVC Section VIII, Division 2.
