  • the method further comprises the step of installing a drawworks subframe 245 onto the substantially horizontal lower mast section, as has already been installed in fig. 6a .
  • the drilling drawworks is mounted to the lower mast section, possibly via a drawworks subframe, prior to the erection of the transfigurable drilling rig system.
  • a drilling drawworks ramp 200 is used, which is positioned, here by a vehicle 230, in line with and connected to the lower mast section 240 ( fig. 6A ), via connection means 208, 209 ( fig. 6B ).
  • Drilling drawworks are provided to the ramp 200, here by a vehicle 233 ( Fig. 7A ), possibly the same vehicle as provided the drilling drawworks ramp 200.
  • the drilling drawworks are allowed to slide over the sliding surface 201 of the drilling drawworks ramp 200 onto the lower mast section 240, in particular onto the drawworks subframe 245 mounted onto the lower mast section 240 ( Fig. 7B ).
  • sliding occurs by operating the winch 205 actuating the winch driven cable 202.
  • the drilling drawworks ramp is removed, as illustrated in fig. 7C .
  • the other mast sections may be connected to the lower mast section, similar to what is shown in figs. 3A-3C or 5a, 5b .
