Works at 32 bars = 320 meter about 1000 feet 
At greater dephts design we use them on both sides to reduce the cable tension force.

Does anyone know what the rules are concerning electrical penetrators.  I understand some people use Blue Globe compression fittings.  Can a multi wire cord be used with a Blue Globe fitting?

Jon,
Agreed, I am concerned of coarse about the buffing temperature.  In my case the ports are in quite good condition, and should need minimal buffing.  The mbt windows are in rough shape but they are not under stress like a port so we can get tough with them.

It looks like GL has similar wording, depending upon actual usage and detailed testing agreed to by GL a service life extension may be granted.  For the person desiring a certified vessel I agree new windows would probably be a cheaper route unless you were very sure the existing windows would pass the required testing.  Scratches are a no-no however so you really need to get them completely buffed out.  The heat produced in buffing may justify annealing however if the windows were manufactured to PVHO standards there's a lot of safety factor built in.

Jon,
Yes, that is what I call the bible.  I just read on page 940 that ABS accepts the extrapolation method to determine remaining service life. The test is very extensive and for a flat disk window  it would probably be cheaper to buy new windows.  I did not see that re- annealing helps.
