You still must consider the tether. This would have to follow the ROV through the system. The tether would have to be controlled. There are tether reels that could be set a some distance into the system to minimize this. Tethers are usually the downfall of ROVs. Create a lot o' drag, though not a real problem here. What you are thinking would be easier, and more efficiently done via a AUV. There would be no tether involved.
