The ''[[catwalk]]'' is the deck located to the side of the derrick floor and between the pipe racks (22). Joints of drill pipe and casing are rolled from the pipe racks where they are stored on the catwalk and hoisted up through the [[slide]] (21) and [[V-door]]. The catwalk is also the primary location to process [[Core handling|core]] and assemble [[Basic tool table|wireline logging tools]].
