Stage three of the full rigging program begins after the rig has been unstepped, masts laid in trolleys and then transported to the place where they will be serviced by the team.
Stage three will commence with a full visual walk around of the rig to look for any structural issues, and notes are made of anything that rings alarm bells with the riggers. The headstays and forestays are then removed and laid down beside the rig. The rods are then all disconnected from the mast, tagged and marked and put down beside the rig. Should the rig be scheduled for painting, it will be hung in the scaffold towers and prepped for paint.
Meanwhile, depending on the plan service wise, the rods will be prepped for re-heading and the lengths will be checked to make sure they are the same length as on the cut sheets supplied by manufacturers (sometimes there are discrepancies and adjustments need to be made). If they are being re-headed then the calculations for adjustments will be made, and how much rod will be lost in the reheating process taken into account.
All the pins, sheaves, turn buckle bodies and associated hardware are cleaned and polished in prep for Non-Destructive Testing survey. The NDT survey will give the indication as to whether any pins or hardware need replacing and rods need reheading. At this point anything that has been flagged or failed by the NDT will be ordered, re-machined or re built, and any extra new parts necessary will be ordered.
