Towing a VideoRay

Postby tom_glebas » Mon Mar 21, 2005 6:13 pm

In certain operations, it is possible to tow a VideoRay. One operation currently being conducted for the US Army Corps of Engineers involves lashing a VideoRay Explorer to a sled and towing it on a stretch of the Delaware River in order to search for Sturgeon. The operation was successful in finding sturgeon in the study area.

For pictures of some pre-operations testing, visit http://scott.bentley.com/USACEDelaware0205/

When would you want to tow a VideoRay?

1. Towing seems to be a practical solution for surveying long stretches, where piloting skills would have to be honed and some kind of positioning system used to maintain course.

2. When currents are too strong for any ROV to operate efficiently.

3. When a skilled operator is not available, but the towing equipment is available.

If anyone else has experience towing a Micro-ROV, please contribute...

Towing a VideoRay

We have been asked by an oceanographic institution to survey the sea bottom their side scan sonar will monitor. They need visual support to confirm/document the data collected. Up to this date, we plan to have a diver towed above the side scan sonar, holding the submersible. Depending on the size of the unit, plan B is to directly attach it the VideoRay. This mission is planned for next week.

Good luck with your mission and let us know how it goes. What is the water visibility where you intend to work?

Thank you Tom. Coastal Ecuador has sediment laden water when close to major rivers, we are then talking in terms of inches. Otherwise mostly OK, but nevertheless at the cunjunction of important oceanic currents. Top visibility is found in Galapagos.

I have successfully towed a VideoRay with the MicroWing conversion kit without any additional weight, having the vehicle neutrally buoyant. Here is a link to the charted data. http://www.rovexchange.com/images/microwing_tow_chart.gif

Cable Length: Feet
ROV Depth: Feet
Boat Speed: Knots

Here is a link to more info on the MicroWing: http://www.rovexchange.com/microwing_order.php

See the VideoRay ROV setup from Imbros in Australia.
