Comments on: What offshore miners know http://blogs.reuters.com/environment/2010/05/11/what-offshore-miners-know/ Global environmental challenges Wed, 16 Nov 2016 08:14:55 +0000 hourly 1 http://wordpress.org/?v=4.2.5 By: wombatmarsupial http://blogs.reuters.com/environment/2010/05/11/what-offshore-miners-know/comment-page-1/#comment-345067 Wed, 12 May 2010 17:04:19 +0000 http://blogs.reuters.com/environment/?p=17299#comment-345067 JohnMetz: When you say “Our government chose not to insist on back-up controls for the BOP. So we have no way to shutdown the well.” I am fascinated just wondering how the US government could have been so lax. It is as if the government was run by Haliburton and an oil man for 8 years or more. And by the way, have you completely excluded BP from the list of actors who could have been responsible for selecting the pressure rating of the BOPs they paid for and had installed?

Swimmer: When you say “It’s certainly possible that a new and unforeseen situation could arise causing a Brazilian well to blow out.” I am reminded of that delightful George W Bush joke about the Brazillian soldiers. How many??!

We are a long ways from being able to control such a volatile environment. Just look at the inability to respond real time to such a disaster. With all of the money and all of the technology being thrown at the problem, we have been helpless to stop the leak.

This is a critical time in our nation. The technology is not ready to safely extract oil from deep water reservoirs. Do we continue to take huge environmental risks or do we take the necessary steps to convert to clean energy.

If they shut down for safety with good reason (e.g. hearing a hiss, equipment recording pressure surge), no one will challenge them. The public perception that oil companies are cavalier about safety is dead wrong.

risenstar: Why do you believe the government could do a better job than BP? I hear this often. I don’t understand the reasoning. And how do you know for certain that BP made a human error? Is this an opinion? A fact? Hearsay? They deny it. What inside info do you have?

JohnMetz: Since 1947, and after about 60,000 offshore wells, there had been no serious blowouts in the US Gulf of Mexico. In hindsight we can now see that the risks are higher than was thought, but up to the day before the event, risks were in fact widely regarded as being low (review above stats). Companies are operating on the edge of science, and that entails risk. Can you be certain that equipment mandated in Brazil or the North Sea is risk free, and if not how much does it reduce risk? It’s certainly possible that a new and unforeseen situation could arise causing a Brazilian well to blow out. Also, your charge of sabotage is astonishing. What evidence do you have? What would the motive be?

If the oil corps want to continue to drill deepwater rigs in our waters, we should mandate blowout preventers that can handle the higher pressures.

Finally, our Coast Guard needs to be equipped with some huge sweepers and a fleet of big tankers that can respond to spills. Make dispersants illegal, they only magnify the damage. Let’s start doing the smart thing and go directly to the heart of leaks/spills and sweep the oil up into freighters and let’s build or equip a refinery to separate the sea water from the oil… leaving the oil in the water to kill marine life and then invade our shoreline is utterly stupid.

That is unfortunate, because her point IS supported by actual facts related to the Deepwater Horizon disaster that she ignores.

First, her errors: The blowout preventer (BOP) is a piece of equipment meant to stop the flow of oil. It had nothing to do with trapping methane bubbles. Secondly, this rig was not transitioning to production; it had just been drilled and its core cemented; it was transitioning to a sealed well, not production.

The author’s basic premise – that automated equipment was involved in or caused the Deepwater Horizon explosion and might have been prevented by greater human involvement – is completely wrong. This wasn’t a matter of stupid automated equipment missing signals smart humans would have caught. Rather, smart humans possibly made a mistake in the cementing or other process, resulting in methane coming into what was supposed to be a sealed drill shaft.

However, the ecological disaster we now face IS due to over-reliance on automated technology. The fact that an environmental disaster is occurring can be traced to the failure of the blowout preventer (but, again, the BOP failure came after, and did NOT cause, the explosion). But don’t blame the technology: additional technology exists for remote actuation of BOPs, technology that is required by Brazil and some governments involved in North Sea drilling regulation. Our government chose not to insist on back-up controls for the BOP. So we have no way to shutdown the well.

In short, the explosion was horrible, although not completely unpredictable (the US govt had warned BP/Transocean about the high methane levels in this field; warning possibly ignored). But it was not due to over reliance on automated equipment. The following eco-disaster was entirely predictable, and caused by political choices made by smart humans.

We split the atom 65 years ago but we can’t remove oil from water??? As soon as that oil hit the surface, April 22nd, government ships should have been there to collect it on the spot. This was not a bad leak, we should be prepared to handle a leak ten and twenty fold this bad, government should take command and remove the oil and send it to a special refinery to separate out the water… then send the bill to the oil corp responsible.

Finding a balance between human mastery and computing technology is a defining challenge of our generation. Too much reliance on technology and you dumb-down the species. Too little, and you miss the full benefits technology can bring.
I’m certain too that the environmental aspects of being in an enclosed mine, where sound and feel are significant, are vastly different from those of an outdoors at-sea area where a shake and a noise can be simply a gust of wind.

Still, the challenge is there. Waiting.

And if they did, and the disaster never happened, would they have been still working after having taken this responsibility?
Try telling **your** boss that you have just avaided a multi-billion dollar disaster by destroying his multi-million-dollar equipment.
