ABSTRACT In order to improve the working conditions for the operators of drilling rigs, the work area for handling of pipes and tubes is arranged on a main deck covered by a drill deck , which has openings closable by hatch cover panels . The derrick is enclosed in a cover, from which tunnels extend out over the drill deck and comprises lifting means for handling of pipes and tubes between the decks. The tunnels are connected to the cover of the derrick by raised enclosures permitting the swinging of pipes from a horizontal position in the tunnel to a vertical position in the derrick, and vice versa. There is a door , at least at one of the enclosures permitting handling of especially long objects, and basically the handling of pipes and tubes can be performed within areas fully pro- tacted from the weather.
