Explosive Welding - The Deepwater Pipeline Connection/Repair Solution

Abstract: After briefly describing the physical aspects of explo sive welding ingefieral terms, this paper outlines how the underlying principles are applied to the making of pipeline connections under water. Using the same basic weld geometry, two general connection types are available -a pipe flange and a sleeve weld. '-The associated systems of pipe preparation, flushing and drying, dewatering, welding, and subsequent inspection receive attention, and in all cases the minimal requirement for operator skill is emphasi… Show more

“…These are on Melville Island in the Canadian High simple tasks readily achieved by either a Arctic (5,6,7). This overall concept of making the equipment required in the bore of the connections by lateral deflection has been pipe including the charge unit, the detanalysed theoretically, simulated in model onation and dewatering systems are inserted form and proved by full scale sea trials before the connection is made.…”
