The decommissioning of offshore structures is a severing intensive operation. Cutting is often required throughout the structure above and below the waterline and mudline on braces, pipelines, risers, umbilicals, manifolds, templates, guideposts, chains, deck equipment and modules. More significant cutting operations are required on elements that are driven into the seafloor, such as multi-string conductors, piling, skirt piling, and stubs which need to be cut at a minimum of 15 below the mudline, pulled, and removed from the seabed.
