Remote Tecno Plug, Pipeline Isolation, Qatar

STATS Group was contracted by the largest LNG producer in the world to provide isolation and reinstatement leak-testing of a 38” sour gas export pipeline in Qatar. STATS supplied two DNV GL type approved Remote Tecno Plugs® to provide a fully monitored leak-tight isolation, which facilitated the safe hot work modification of 2” bypass pipework connected to the gas export line around the 38” emergency shutdown valves.
The isolation scope was completed as planned, enabling the bypass pipework modification to be completed incident-free and within the planned shutdown. The successful delivery of the project is testament to the teamwork and good communication between all parties.
Utilising the Remote Tecno Plugs provided the operator with a very high value proposition, meeting their sustainability development goals and eliminating the need to flare 80 km of sour gas inventory from the 38” trunkline. The double block isolation provided safety assurance to carry out the hot works which improved plant integrity and led to a reduced shutdown duration, ultimately increasing operational performance.
