Oil and Gas Production Installation Platforms located in the sea, regardless if drilling rigs or mooring/loading points are marked by a distinctive light character, which enables the seafarer to identify it as a production platform. This morse code is SHORT SHORT LONG. That means, you see two short flashes and a long flash which represents the letter "U" and and gives notice of a production installation. These rigs or mooring points have special restrictions and precaution areas (passage with a good distance, supply by vessels, pipes in the water) and therefore are specially marked. The Admirality List of Lights mostly do not contain all rigs, only the major ones. The smaller ones are often replaced and special exploration rigs exist in the vicinity of the oil and gasfields to search for new sources.
