ABERDEEN, UK -- Subsea 7 has acquired the exclusive global license rights for a new subsea hot tap technology, known as Subsea Grouted Tee (SSGT).
The technology enables intervention activities to be carried out on high and low pressure subsea pipelines, without the need for major hyperbaric welding operations. SSGT allows companies to intervene into pipelines that are still under pressure, negating the requirement for production shutdowns. Further benefits are that SSGT can be deployed by mechanical divers, eliminating the need for lengthy welding qualification.
Following completion of the JIP and further development by Subsea 7, the Subsea Grouted Tee technology has been verified by DNV and is now available for offshore use.
