Diving and Training for Polluted
Water Diving Operations
One of the world’s leading authorities on diving in high risk environments, Steven M. Barsky, recently
worked with Trelleborg Protective Products to update their educational video on diving in contaminated
water and here he gives us an insight into how this video was made...

Viking approached me again to discuss updating the
Viking video with new material. Since the prior program
had been filmed entirely in the U.S., and Viking is a
global firm, they wanted to show how Viking suits are
used around the world. In addition, since they had just
released their new HDS suit – “Haz-Mat Diving Suit” –
made from a new rubber coated textile called” Nitecs,”
they felt this would be an ideal opportunity to show
divers using this rugged new material in challenging
environments.

Nautilus SRL – Commercial Diving in the
City of Canals

   Nautilus SRL is a commercial diving firm who works
in the polluted waters surrounding the city of Venice.
While Venice is certainly one of the most charming
cities of Europe, it’s a known fact that raw sewage and
waste water are regularly dumped into the canals that
weave throughout the city. This means that any diving
in the lagoon exposes the diver to a wide range of
biohazards.
   We filmed aboard the Nautilus SRL barge, which was
deployed specially for us, and watched their procedures,
with the city of Venice serving as a backdrop for their
work. They normally dive with tethered scuba gear, full-
face masks, wireless communications, and dry suits.
   Although most people think of Italy as a warm
country, during the winter months, ice actually forms
on the surface of the lagoon, so the divers appreciate
not only the biological protection afforded by their
equipment, but also the warmth factor when the
lagoon freezes over.
                                                                  Nautilus SRL is one of the leading commercial diving companies in Venice, Italy. Each of
