A variety of cutting technology is used in support of decommissioning offshore structures in the Gulf of Mexico. The purpose of this paper is to describe the science and technology of nonexplosive severance techniques, and to examine their environmental, physical, safety, and activity requirements. Abrasive water jet, diamond wire, diver torch, mechanical methods, and sand cutters are the primary nonexplosive cutting techniques applied in the Gulf of Mexico. The technology of nonexplosive removal techniques has not changed dramatically over the past decade, but technological progress continues to be made, most notably in abrasive water jet and diamond wire technology. A review of each nonexplosive cutting technique will be described within and across each stage of decommissioning. |
