Full-scale tests of a subsea grout mixing and injection skid unit in the North Sea in June verified both the overall functionality of the injection system used for installing a Subsea Grouted Tee and the grout's ability to cure at seabed temperature and pressure. SSGT technology mechanically connects an off-take fitting to an existing pressurized pipeline, providing an alternative method of hot-tapping into high and low-pressure pipelines without major welding.Applying the technique to marginal satellite fields could help develop such prospects by dropping the cost of linking to export infrastructure. SSGT also offers a more efficient means of making emergency interventions.Backgroun...
