Re: [PSUBS-MAILIST] Reverse engineering in CAD
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.
