Subsea 7's Hot Tap Technology Tested

Wednesday, September 09, 2009

Subsea 7 Inc (OSE Symbol: SUB) has announced that following a three year development, testing and qualification program, its new subsea hot tap technology - Subsea Grouted Tee (SSGT), has successfully completed offshore trials in the North Sea and further demonstrated the technology's deepwater, diverless potential.

Following an extensive DNV approved onshore testing program in test tanks and laboratories, the offshore trials of the SSGT technology involved the mobilization of a subsea grout mixing and injection unit, complete with test tee assemblies, on Subsea 7’s Seven Pelican dive support vessel (DSV). The skid mounted mixing unit was developed to enhance diver based hot tapping operations and also allows the SSGT technology to be utilized in deep water, where pumping from the surface could be challenging.
 
During the trials, the mixing unit was deployed to the seabed where divers carried out the installation and hook up operations. After grout injection into a test tee assembly followed by a 24 hour grout curing period, the unit was recovered to the vessel where the grout quality test was successfully performed.
