Since the first crude oil pipeline has been constructed by the end of the 19th century to transfer the oil and hydrocarbons from one location to another, some of this pipelines life time have been expired, in such a case the rehabilitation or replacement the old line by a new one is essential to avoid access leaks, Shutdowns, high maintenance cost, Safety Hazards & Environmental impacts. In some cases it’s more visible to replace the old line by a new one and DEMOLITION of the old line. The aim of this paper is to introduce safe, economical & practical techniques to implement such job which have been proven through a successful demolition of 50 Km of crude oil pipelines with various diameters starting from 16” to 48” by using of high productivity construction techniques in the demolition activity through a proper safety risk analyses.
