Update on max depth for BR2

[EliotBR (Eliot)]

Hi @rangewider,

@rangewider

The last thread I see for discussion of maximum depth for the BR2 ended in '18. I wonder where we are since then.
…
we need to get to 200m and do some physical manipulation of an installation with the gripper.

Failure occurs at the weakest link, so all the pressure-resisting components need to be considered, and same for things like tether communication length. With an aluminum 4" enclosure and WetLink Penetrators, 200m should be well within the ratings

Note that the slim tether is only rated to 200m for communication, so if you want to actually move around at 200m depth then you’ll need a standard tether.

@rangewider

I saw mention of an all aluminum 4" that would be required, but I don’t see that as an available option.

@EliotBR

Sorry about the confusion here, we’ve removed the product page for the old aluminium enclosure because they’ve sold out, and the revised (locking) version will be in a combined product page of multiple tube sizes, which hasn’t been made public yet because the new locking enclosures haven’t yet been released.

I believe the new enclosures will be launching this week
