Purpose: The purpose of this presentation is for general knowledge only on how “underwater welding” is carried out. Safety is also emphasized here as we are dealing with two types of activities, Diving and Welding. One must remember that underwater welding is a different world, and so special precautions are adhered to for maximum safety of the welder/diver. Introduction: Underwater
Types of Pipeline in Oil & Gas Industry: Injection lines: Pipelines injecting water / steam / polymer / gas into the wells to improve the lift. Flow lines: Pipelines from the well head to the nearest processing facility. Trunk lines / Inter field lines: Pipelines between two processing facilities or from pig trap to pig trap or from block valve
