BRION22 WHITE SHARK SCIENCE EXPEDITION
Shark observation cage upgrade begins at CNIMI
Drummondville, July 30, 2022 — In order to study sharks in their element, the expedition will deploy the ORS aluminum shark observation cage after it has been modernised by engineering students at CNIMI (Centre national intégré du manufacturier intelligent). The cage designed by ORS and built by Centre de formation professionnelle Paul-Rousseau for our very first expedition in 2000, is currently being retrofitted to meet current commercial standards¹.
During the expedition, the cage will be secured alongside the vessel to allow scientists to observe and film the white shark swimming freely*. Sharks will not be able to pass between the cage and the vessel and a ladder will remain in place to allow for the immediate and safe evacuation of divers.
In order to reduce the risk of injury to sharks, and to make the cage safer and more comfortable for the divers, CNIMI engineering students under the supervision of Dr. Marc-André Gaudreau (UQTR) are carrying out the following modifications²:
• Design, manufacture and installation of a guard rail around the top of the cage with at least 300 mm of freeboard when fully loaded to reduce the risk of a shark swimming or becoming entangled above the cage floating at the surface.
• Polish welds where necessary to reduce the risk of lacerations or other injuries to sharks colliding with or rubbing against the cage.
• Replace hinges and install latches on all openings to prevent sharks from accidentally entering the cage and getting caught.
• Design and manufacture of a floor equipped with footrests to ensure the stability of observers and videographers.
• Design and manufacture of observation port shutters to prevent sharks from accidentally entering or getting stuck in the cage.
