Case Study: Deep Water Pipeline Repair

An 18" gas pipeline operated by Williams in the Gulf of Mexico had been damaged by a cable-laying vessel dragging its anchor along the seabed during bad weather. The 750m deep pipeline was forced to run at a reduced pressure for safety reasons until remedial work could take place.

The solution was a two stage fix using a grouted repair clamp around the section of damaged pipeline and a grout bag to support the additional load.
