We
were working on a Hydro-electric plant. The water supply for the plant
comes from a tunnel through the mountains. Every once in a while
the have a vertical shaft drilled down to the main tunnel with the large concrete structure around the shaft. These act as surge tanks when the shut the water off going through the plant. When we were mobilizing the job they had an emergency shut down and the tank in the pictures filled up with 3' of water immediately. It was lucky nobody was sucked back into the hole when the water went back down a few seconds later. |

There
was supposed to be some kind of obstruction in the tunnel keeping the plant
from coming up to full capacity. We went down to look for the obstruction.
None was found. They had to shut down the power to Lima, Peru for 6 hours
during the height of their carnival season.

The vertical shaft was about 100' down to the waterline while we were working and the water depth was 380'. It was a one dive deal with 3 or 4 days decompression in a mini sat system the size of a deck chamber. Mark Trimmer was the diver who locked out. |
