He was "responsible for safety of all crew and clients". So, he voiced that the sub wasn't safe. He was doing his job. If he hadn't been fired maybe he would've been able to enact changes to prevent a disaster, so I disagree that being fired was an ideal outcome. Being fired is only an ideal outcome if you believe that Lochridge wasn't trying to enact change but only to avoid liability. I don't see a reason to such cynical view.

Lochridge was also a submersible pilot. Being fired was an ideal outcome for Lochridge, because Lochridge was therefore not piloting the sub this week.

  The ideal outcome for Lochridge, I'm sure would have been the sub being modified so that these problems did not occur. I'm pretty sure he does not set the utility of other peoples' lives at 0, so their surviving along with him would definitely be better. So this has to be the second-best outcome at best.

    That's true. What outcome is ideal depends on the priors, I suppose. If the company not listening to Lochridge is a given, then being fired is better than not, and having to go down on the sub. The company listening to Lochridge is better than the company not listening to Lochridge. The company putting safety first and engineering something that met Lochridge's standards from the outset is better than the company listening to Lochridge when he brought up problems. And so on.

    I think they couldn't modify the sub to be safe - the big worry is the integral part of the sub (and the one with the highest cost in this one), the composite pressure hull. You cannot ensure its safety, since you cannot evaluate it for growing defects. As is best practice for all other DSVs in the world that use metal pressure hulls. I suspect a metal hull and all it entails (way more complex design and careful selection of materials, equipment, passenger space etc.) would have cost too much.

  > Being fired was an ideal outcome for Lochridge, because Lochridge was therefore not piloting the sub this week. What an absurd thing to say. Not having the sub sink has all the upsides and none of the downsides of having it sink. Ergo, being fired is guaranteed not to be optimal.

If he resigned then it's plausible to speculate that he was trying to avoid liability, but he was fired. Someone didn't want him to do his job regardless of what he himself wanted.

I think there was simply no economically feasible alternative to the composite hull, so Lochridge was fired. I also suspect that if you go with a metal hull, you don't have positive buoancy anymore - you need syntactic foam. You need larger thrusters, those are heavier too, so more foam etc. The engineering becomes harder and also costlier, in addition to the material and equipment costs. What you gain is the ability to evaluate your pressure vessel for growing defects - which you didn't do in the first place (and can't do) with your composite hull.
