FoundOcean has completed the installation and grouting for a clamp repair to an 18” pipeline in the Gulf of Mexico. Saipem America awarded FoundOcean the contract to repair the damage caused by a vessel’s anchor being dragged along the seabed over the pipeline in bad weather, at a water depth of 750 meters.
The seabed was dredged around the damaged area of the pipeline. An ROV maneuvered the two steel half-shells of the clamp into position and pre-tightened the bolts. FoundOcean then connected the hose to the inlet valve on the clamp and delivered the grout using its reliable and cost-effective deepwater grouting umbilical system. Due to the extra load, a fabric formwork was installed under the clamp to provide more support.
In total 28 tons of cement was used: four tons for the clamp and 24 tons for the fabric formwork.
