Hi Carl,
I can't claim any expertise. Most of what I know is academic.
From my research and studies, temp limits are not included
within the specifications of ROVs or submersibles. Usually,
the list covers : depth rating, weight, energy type, propulsion,
telemetry, and deepest dive to date. For example, the general
specs given for the "SUPSALV" is 29K ft depth rating, 20.5K
deepest dive, weight-13K pounds, power-80 hp electric/hydraulic
3phase 2800V No standard temp data.
Also, realize that some research ROVs and submersibles dive thru
varying temperature ranges, from surface temps transitioning thru
the thermocline where the temp can approach 0 degrees celsius
at 5+K depth and radically go up to 400 C at themal vents though
this is in very close proximity to the vent, the ambient temp at depth
remains around 2degrees C around the vent. However, manipulators
that take samples directly from the source must stand up to the extreme
temperature changes.
It seems to me that pressure is the primary criteria and not temperature.

What is the maximum underwater temperature an ROV can tolerate?

Thanks Ian,
I checked the DynaMechs site and I can envision applications for
controlled-networked applications for excavation, repairs, and
rescue ops using ROVs controlled from a psub or onboard ship.
A sub could hover at a safe distance while commanding a group
or swarm of rovs [ with manipulators, welders....etc. ] into high
risk areas or at greater depths than the sub could go or into areas
too small or sensitive to turbulence [ ie., archaeological digs ] for
a large boat to venture. Even one ROV with camera and manipulator
working in tandem with a manned sub would reduce the power
overhead of the sub.
Oh well, it's easier to think of these things than take them to task !

Hi Steve,
I've not been doing much work on the DynaMechs K350 simulation, but I do
have some clues to follow once I get sometime to work on it. Mainly, I
need to recalculate the moment of inertia every time I adjust the VBT
(since the mass of the vessel will have changed).
Once I complete the control software for Solo I'll revisit the K350 sim.
It's my (long term) intend that the control software can be interfaced to
the simulator as well. So you could try out a control setup/configuration
in the simulator, and if you like it, then you can use the same configuration
files to configure the controls of a sub.
Ian.
