Hi all,<div>Could have been condensation on the port. I’m going to leave that for now and just tackle the valve.</div><div><br></div><div>With regards to cost.

I tried to take it to the chamber in Aberdeen. Had it all booked but then the day before I was to leave, they said they wouldn’t do it as it’s home made and if it failed might damage their equipment. There are no lakes here and to get 100 meters in the ocean would take about a 4 hour trip just to get there and at the price of the hire boat, I had to go closer in.</div><div><br></div><div>I told them to get me as deep as they could.

<div dir="ltr">Congratulations James. Always great to see a successful depth qualification test. To sort out the leaky scuttle valve, I would build a bench pressure test and retest after disassembly, inspection and repacking.</div>

<div dir="ltr">As you note, K250 have seen much deeper depths than 50 m. If it were me, I would shoot for depth qualification of 1.25 times 250 ft operating depth or 313 ft (95m). As well built as your boat is, a depth qualification to 95m should be no problem.</div>

Was that seawater at the viewport? I didn't see a taste test. Could simply have been condensation, yes? Good news, though. Now you can sort that valve out and go diving. What a great way to end the summer!!!

<div>Hi all.
<div>I finally managed to do a deep test. We get about 60 meters reasonably close to land. There are some deeper places but they are too far out to sea to get to easily. </div>
<div>I was trying for 50 meters which is no where near what she should be tested to I know, but it’s deeper than she has ever been or likely to go from now on.</div>
<div>There was 40 meters of cable and 10 meters of strops, but the deck length gobbled some up and they left a turn on the winch. We drifted with the tide for an hour with the sub at the end of the line. It’s very flat on the seabed where we were so nothing to crash into.</div>
<div>So in the end I got about 43meters. I’m slightly disappointed I couldn’t get to 50 but there we go. </div>
<div>The crew haven’t sent me the rov footage yet but when they do I will modify the video to include it. I couldn’t look at the footage as they were doing it fearing the sight of a crushed sub coming into view. I went and hid on the bridge and tried to gauge the reaction of those looking at it.....</div>
<div>Anyway, I’m not sure what to do with the weep on the viewport and valve. Reseat the port? Any ideas?</div>
<div>Regards</div>
<div>James</div>
