Remote Tecno Plug

STATS GROUP Stand: E30

The Remote Tecno Plug® system is a piggable, remote controlled, tetherless isolation tool. The pipeline isolation plug provides a high degree of flexibility and eliminates the need for tethers or specially modified pig-trap doors. The Remote Tecno Plug provides a fail-safe double block and monitor isolation of pressurised subsea pipelines while the system remains live and at operating pressure. The Tecno Plug is DNV type approved and complies with all relevant subsea pipeline isolation guidelines, ensuring safe worksite conditions for divers from breaking of containment to pipeline reinstatement.


The dual seal configuration of the pipeline isolation plug provides an annulus void between the seals which can be pressure tested to verify both seals are leak-tight before maintenance work is carried out. Both seals are leak tested with full pipeline pressure. Once the seal integrity has been proved the annulus is then vented to ambient to create a zero-energy zone, providing effective double block and monitored pipeline isolation. The large section elastomer seals are highly compatible with poor pipe surfaces and are engineered to suit corrosion or ovality issues ensuring a leak-tight seal even in ageing assets. The isolation plug has the ability to monitor the isolated pipeline pressure, this is achieved via a dual sealed pressure impulse line and ensures there is no leak path through the tool. If required, pressure

application through the isolation plug is attained by adding an additional module containing a second equalisation valve. Pipeline isolation safety is ensured as two separately controlled valves need to be functioned to allow pressure communication through the Tecno Plug.
