Method of moving a drilling rig on skids or rollers which are positioned under the derrick. It mostly refers to the process of sliding the rig off from the wellbore or moving it from one well slot to another on a fixed offshore platform. A skid is usually a steel frame on which portable equipment is mounted to facilitate handling with cranes or flatbed trucks. The skid is robust and is usually designed with attachment points for hooks, chains, or cables, and has at least two lengthwise beams to facilitate sliding the equipment into place on the rigsite
