FoundOcean completes GoM pipeline grout job for Saipem

Offshore staff

MARLOW, UK – FoundOcean has completed installation and grouting for a clamp repair on an 18-in. pipeline in the Gulf of Mexico under contract from Saipem America.

The seabed a water depth of 750 m (2,460 ft) was dredged at 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 deepwater grouting umbilical system. Due to the extra load, a fabric formwork was installed under the clamp to provide more support.

In total 28 metric tons (30.86 tons) of cement was used: 4 metric tons (4.4 tons) for the clamp and 24 metric tons (26.46 tons) for the fabric formwork.

The pipeline damage resulted from an anchor drag during bad weather.
