Fathom ROV Tether resistance to chemicals

Good morning,
We are currently using the bluerov in a Firefighter project. Given that many times in our scenarios it happens to work in contaminated water (petrol and oil based pollutants) I was wandering if anybody knows the resistente of the Fathom Tether to those agents. Expecially because those pollutants usually floats as the fathom Tether and therefore the exposure is high.

Thanks a lot

We have had a lot of exposure to hydraulic and mineral oil in various test tanks and the Fathom Tether never suffered any noticeable damage. We also clean the tether with 70% or 95% if it’s been contaminated or discolored and that does not seem to bother it much either. Acetone will alter the jacket material, but not quickly. We have not tested in gasoline or foam additives. Hope this helps.

Thank you very much, it already helps to have some information, although in most cases we have gasoline spills so that’s what we are mostly interested in. We have noticed great damage on silicon based tools or scuba diving gear when exposed to gasoline that’s why we are interested on the cable resistance.

Thank you very much for your quick reply.


We want to see what it does as well. I have scraps of tether here at our shop and may test this tomorrow and will share the results… A good test is to cut a short length of tether, place it in a sealed container with the chemical (gasoline in this case) and leave it at room temperature and check it after 24 hours. If you do this, be careful and store the sample in an appropriate location and sealed to prevent vapors.
