<div>Hi Hank,</div>
<div>I don't know what the "rules are on them yet"</div>
<div>I think their pressure rating is well below what they have </div>
<div>been tested to by Emile (3000ft).</div>
<div>The European Psubbers use 2 per penetration, 1 either side of the hull.</div>
<div>It would depend on the configuration of the multi strand wire as to how</div>
<div>it sealed up. Experiment or test? </div>
<div>I put two wires through the same penetration by buying an item that</div>
<div>fitted in to the Blue Globe Gland & potting the wires in this.</div>
<div>It was basically a pipe with an outside lip to stop it extruding in through</div>
<div>the BGCG & an inner narrowing at one end to stop the potting from</div>
<div>extruding through.</div>
<div>In hind-site an elbow may have been good to pot in to.</div>
<div>Regards Alan </div>

<div><span>Jon,</span></div>
<div><span>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. </span></div>

<div><br clear="none">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.<br clear="none">

<div><span>Jon,</span></div>
<div><span>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.</span></div>
