SUMMARY OF WORK

RIVERSON ENGINEERING was able to successfully execute the grouting of pipeline free span correction works at a water depth of EL (-) 65 meters. The grout bags were made of industrial grade poly-propylene fabric bags with a 1.5” coupling for the grout hoses attachment. Prior to the installation of grout bags and grouting, divers were deployed to conduct a run through inspection for conformity check based on the Client's underwater survey. Once confirmed, a slurry of mixed grout was pumped down from a work vessel deck via 2”/3” diameter series of hoses to 7 different locations on the 18”/24” pipeline that needed correction until the divers indicated that the bags were full.
