Isolation & Intervention

Isolation of pipelines and pipework systems is a key requirement for the maintenance and modification of oil, gas and petrochemical infrastructure. STATS Group has access to a wide range of pipeline isolation techniques and offers a consultation service to assist operators in assessing the optimum solution for their pipeline isolation challenges. Our comprehensive range of products and services provide the highest practical pipeline isolation integrity for a vast variety of applications.

STATS supply isolation devices from ¾ inch to 54 inches that are compliant with 1D to 5D bends. Our extensive product range allows for isolations to be undertaken safely and efficiently on ambient or pressurised systems. This product range also allows for isolations to be undertaken where full bore access is not available. STATS have designed and manufactured a number of world-beating products, which have led major operators to reassess how they manage isolation and intervention projects.

DNV GL Type Approval

STATS Tecno Plug® and BISEP® 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.

STATS have an extensive track record of providing temporary pressurised isolation of onshore and subsea pipelines in a range of sizes. Isolation operations have been undertaken in most pipeline mediums including, gas, crude oil, liquid CO2 and condensate.

Non-Intrusive Inline Isolation

Non-Intrusive Inline Isolation

The Tecno Plug® provides fail-safe double block and bleed isolation of pressurised pipelines while the system remains live and at operating pressure. Dual seals provide a zero-energy zone to enable maintenance work on pressurised systems to be carried out safely and efficiently.

Hot Tapping and Plugging

Hot Tapping and Plugging

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.

Small Bore Hot Tapping and Plugging

Small Bore Hot Tapping and Plugging

The patented BI-STOP™ provides a unique hot tap and plugging system to address challenges with small-bore pipework that have absent or limited isolation facilities. This cost-effective solution enables small-bore pipework to be isolated, cut and if required, terminated with a full-bore valve whilst the system remains live.
