Straightening the pylon

Yesterday a crew of 3 divers attempted to straighten the leaning pylon. Due to limited divers, the process took about 3.5 hours.
Lift bags were used and to keep it simple, only 5 of the chain/spectra lines were adjusted. The initial lean from the time of installation was to the west, and as illustrated in the picture, yesterday's maintenance lessened the tilt.
Also installed during yesterday's work was a rubber washer for one of the two bolts at the base of the pylon. As the picture suggests, the pylon is still twisted. However, we were fairly successful in lessening the pylon's tilt.
