ABSTRACT
One third of the estimated global reserves of oil and gas, viz., 1.3 trillion barrels of oil and 6.2 quadrillion cubic feet of gas, occur in continental margin sediments, which cover about 28% of the oceanic area [1, 2]. In developing these natural resources for human benefit, a variety of offshore structures have been developed and utilized to meet the need. These structures are used to facilitate the process of geophysical reconnaissance, exploratory drilling, production, and transportation of offshore oil to the essential infrastructures located on land.
