We had a similar case in a power plant up here in Quebec a few years =
back.
The differences are that the guy used ice diving techniques and he was =
asked
to inspect the exit pipe instead of the intake. Safer you would =
think...

The power plant was shut off but as small residual flow was going =
through
it. Therefore the turbines were turning ever so slowly. This was enough =
to
create a current similar to an under toe close to the turbine. Because =
of
the shape of the tunnel, the tender had difficulty "feeling" the diver =
at
the end of the rope he kept giving him slack. Eventually, the rope got
caught by the turbine, the diver got reeled in, knocked unconscious and
drowned. He is now part of the coroner's second thematic report on =
scuba
diving deaths in Quebec.=20

Thanks but no thanks! I will leave the commercial stuff to the =
commercial
divers.
