Full cleaning and validation

Yesterday, 18 July 2010, a full cleaning and validation was completed. The validation CT was plugged in at 12:45. Cleaning was initiated by 3 divers at 14:15 and lasted for 40 minutes. All spectra lines, chains, and cables were inspected and confirmed to be in good working order. Copper screens were cleaned and replaced. There was a moderate to heavy fouling of the pylon from the algae build-up. The CT was then removed at 16:15.

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.

Basic Cleaning

On 4 July 2010 a basic cleaning of the pylon and the instruments was completed. Chains were scrubbed and everything was observed to be in good working order.
