There’s a strange sense of scale on that thing. You wouldn’t immediately look at it and say that two people can fit inside for 30 days. EDIT: 30 days between maintenance. I’m a dirty skimmer.

  What? > Alvin enables in-situ data collection and observation by two scientists to depths reaching 6,500 meters, during dives lasting up to ten hours. Maybe you misskimmed: > Alvin is a proven and reliable platform capable of diving for up to 30 days in a row before requiring a single scheduled maintenance day

    I did skim! :) Don’t do that.

  I think it's 30 days of diving, not 30 continuous days submerged. You can use it a whole month before you need to take a maintenance day. There's a 3d panorama view of the interior of the sphere linked from the article - I doubt anyone's spending more than a day in there at a go, let alone with someone else. Edit: apparently, it's 3 people - the pilot and 2 scientists.

As a US Navy-owned submersible, Alvin also undergoes extensive safety evaluation under the Naval Sea Systems Command SUBSAFE program: https://ndsf.whoi.edu/its-official/ https://ndsf.whoi.edu/its-official/ Other manned submersibles undergo classification from groups such as DNV: https://www.dnv.com/services/manned-submersibles-1102 https://www.dnv.com/services/manned-submersibles-1102 Yet OceanGate seems to have avoided this kind of safety classification: https://oceangate.com/news-and-media/blog/2019-0221-why-titan-is-not-classed.html https://oceangate.com/news-and-media/blog/2019-0221-why-tita...
