Information
has gloss	eng: The Helicopter Landing Officer, also known as HLO is the most vital part of the operating team for offshore helidecks (A helideck is a purpose built helicopter landing area, usually on a ship or offshore oil/gas installation) Over the years the offshore oil exploration and production business has relied upon helicopters as the main method of transferring personnel to and from their workplace. Traditionally, and legally these days, the appointment of an HLO is the responsibility of the ship or installation operator. In the early days of offshore helicopter work, the basic requirements of safety were met by persons who would have a primary task (Deck supervisor, Crane supervisor etc) and would take responsibility for the helicopter crew change as a secondary task.
