FoundOcean has developed and executed grouting procedures for Subsea 7 operations at 5,300 feet (1,615 meters) in the Gulf of Mexico, exceeding its previous operating depth levels.
Prior to this, FoundOcean had operated at 4,500 feet (1,370 meters) when it installed a crossover fabric formwork in the region. At that time, FoundOcean’s project teams considered this to be nudging the limits of safe and practical surface-to-seabed grouting operations.
But when Subsea 7, based in Houston, contacted FoundOcean with its proposal, FoundOcean rethought its current deepwater grouting methods, which yielded an enhanced solution for a depth that equaled more than three times the height of the Empire State Building.
FoundOcean completed the non-routine work for Subsea 7 in June without incident.
“Due to the depths involved, we had to ensure that we could deploy our equipment and execute the procedures safely and effectively,” commented Pauric Whelan, FoundOcean’s engineering manager, who is based in Houston. “This project forced an entire rethink of our deepwater procedures, and, when we finally mobilized, our planning and contingencies provided us, and our client, with a high level of reassurance.”
