I don't know who Daniel is...

(I tend to leave my PM box full because I generally don't like communicating though that medium, it's nothing personal).
I never claimed any knowledge on the impact to biological systems. Please cite, specifically, where I did so in previous posts. I never provided
any analysis of anything. Again, where did I say this? I simply said, we need to wait for such an analysis before making idle speculation left and right. I honestly don't know how you missed that. Agreed.
Your claim is implicit in the notion that you can assess this risk. If you can't, then really what you're saying about the money involved is meaningless as anything save an academic exercise. For the rest, incoming!

If that's the case, you need to re-evaluate your position on this moral objection. It happens all the time in real world engineering. What you need to remember is that it may only cost $1M for a better valve, but that valve is just one of thousands upon thousands of components in a system that could "just" be upgraded "in case." And then you end up with a billion dollar oil rig that no one can afford to use.
No one got the Daniel reference... what a pity. Daniel in the lion's den, oh well.
For the quote above, here would be the questions raised:
Thousands of components, couched in the notion of "upgrading" rather than a basic safety standard. Your conclusion is a rig that would be prohibitively expensive. Please cite.
You suggest I re-evaluate my moral position, which implies you have one here as well. Please share.

That does not mean there are no process-control standards on oil rigs.
What standards are there, that are relevant to this? What do you call a standard which is held in countries from Brazil to most of European nations. The standard of a blowout prevention valve was not employed, even though it is affordable to other nations who profit from oil exploration. In the absence of that, other measures would be meaningless under that kind of pressure (210,000 gallons per day from a well-head), and THAT is the "matter of time" issue. This is putting aside the possible causes for the explosion, which I am not going to speculate about.

Then you misunderstood the point of what I'm saying. Again, it is not enough to sit there and say "see, if only they had replaced that valve for a million more bucks. They were so cheap, and look what happened!" You have to look at the overall extent and complexity of all the critical components that "could" be upgraded. Then you have to selectively pick which are deemed to be the best allocation of money to "beef up" and which are not. For example if those pipe valves never had problems in rigs for 10+ years, it doesn't make sense to spend the money there. If (for example), on the other hand, the pipe lines are notorious for problems, then spending the money there is more justified. As I said earlier, such an analysis needs to be carried out by experts to determine the cause of this problem and how responsible BP is. Anything else is pure speculation - and nonsense.
A lot of ifs there, but still being used to make an argument that is fairly important. This statement combined with your quote about risk assessment raises the following question: Without understanding the environmental impact of past and future slicks, and with no definitive statements or evidence, how are you engaging in anything but speculation in a different direction? While we're at it, you said pages ago that it seems BP is at fault, but that evidence of gross negligence is absent. While I agree with the former, and the latter is a matter of record in USA courts (see a link I provided you re a settlement in Alaska), both were assumptions or guesses on your part, which you then proceed to decry and challenge if others make it without semantic uncertainty couching each phrase.
As for an implicit view,speculation as to the cause of the explosion is purely speculative, but the absence of a standard safety feature is not. Putting rhetoric aside, you present a dual view, that speculation should be minimized (very wise), and on the other hand you speculate about the affordability of some equipment albeit always in the hypothetical. It seems your agenda is based in your own industry, which is an understandable emotional reaction, but unwarranted. Aerospace is vilified for a number of fair and unfair reasons, but above all people are just afraid of something falling out of the sky on them. That, is a very unreasonable fear, given a reasonable assessment of risk, but it doesn't qualify you to assess the risk of a far more global event such as this. To reference such a notion, implies that you believe it applies to this situation and that you know how to do so. Risk assessment in ignorance isn't really an assessment, it's a kid skateboarding on a rail without a helmet.
