It’s difficult to comprehend the varied and complex piping systems that allow a rig or a drill ship to operate successfully and safely, but they’re an integral part of what’s happening every day. These piping systems contain a multitude of valves built to multiple specifications to handle a variety of flow control challenges. They also control various system loops and contain pressure relief devices.
