It's funny really, but a sign of the times. Oil rig mishaps have occured throughout the history of off shore oil production as has storm damage. But it isnt until global supply is stretched tighter than a drum that each little mishap becomes major news.

It looks like it might just be one of the ballast tanks took on water. Could be as simple as pumping it out to put things back the way they were.

By the way Thunderhorse is not on production yet. It is scheduled to start up in September at about 250 Kbpd. The rise in oil price is only related in that the traders see Emily building and if there is a bunch of unknown damage out there getting hit by another one will likely create big problems and possible supply disruptions.

It's kind of funny that you say it that way fox. With the advent of the internet I have become a hurricane junky. I live in Utah but it's so easy to get maps from the net and watch the things roar ashore that I can't help but watch with a morbid curiosity. Then in the last year or so I can add PO to the whole situation and, blammo they effect world economics.
You observed it from the start
Now you’re a million miles apart
As we bleed another nation
So you can watch you favorite station
Now you eyes pop out your sockets
Dirty hands and empty pockets
Who? You!

$this->bbcode_second_pass_quote('', 'I')t looks like it might just be one of the ballast tanks took on water. Could be as simple as pumping it out to put things back the way they were.

It indeed seems like one of the pontoons took-on a lot of water. The waves could never be so high that they have flooded the deck. That means that the pontoon must be damaged under the waterline. It depends on the amount of damage how long it takes to repair it. For all we know the entire pontoon could be sheared-off and the thing is resting on air pockets in the legs.

Furthermore the rig was also not designed to list so badly. This angle puts some enormous stresses on parts of the structure, exceeding the design threshold by far.

And lastly when these types of things happen to new constructions it usually implies design error. That might not be fixable on the spot, so the thing has to be pulled back to shore. I think that even the best case scenario implies a few months of hard work and good weather.

The worst case scenario?.

OH NO......Not Thunderhorse.

In Business Week there was a huge cornacopian article about how oil prices were headed for a collapse. Next to the article they had a huge picture of the Thunderhose plaform with a caption that read new hightechnology oil production will squash oil prices.

These cornacopians are sounding a lot like Bagdad Bob who went on Iraqi TV just days before the city fell saying how the Iraqi army was winning the war. Funny thing is a lot of people beleived him but reality eventually caught up to him and his lies.

Newspapers quote informed sources that saying it will take 3 to 4 months to repair, or possibly may be a total loss. The one billion $ cost is covered by insurance. I am curious if anyones knows exactly how they will be able to fix this.
$this->bbcode_second_pass_quote('', 'C')rews placed aboard the BP operated Thunder Horse platform in the Gulf of Mexico have restored partial power to the platform, and have begun pumping operations to restore the platform to a normal marine configuration. The crews have also retrieved the platform’s data recorders, which will be used in the investigation into the cause of the stability imbalance that saw the platform list to port at an estimated 20 to 30 degrees.
The crews boarded the BP operated facility today following safety evaluations that included reviews by BP staff and the US Coast Guard’s Federal On-Scene Commander, and an underwater inspection of the facility by remotely operated vehicles (ROVs)

I had no idea those rigs were so complicated. How is the "head" held in place over the well? Is it buoyant? What would we see if we looked under water--are there supports going all the way down to the sea floor? I assume that crews stay out there for weeks or months at a time, so there must be living quarters somewhere too, right? And why do they need so many cranes?

Hey folks from what I have seen in the various sources of oil and gas press I go to BP is just getting out onto the platform to have a look at it....the rest is here is supposition.
Three to four months isn't a big deal....what is a big deal is if they can't sort out the problem and get the thing righted before Emily's tail (or the one after that) gives it another swat. This is a big semi-sub platform so I suspect towing it in present condition is out of the question.
250 kbpd is a big deal...but since it isn't in the market now and wasn't expected to hit the market until Sept or Oct I suspect it's inoperation will only affect oil 3 month out future and not the spot. Mind you we are dealing with traders who make Chicken Little look like Budha.

The drilling sites don't need to be under the platform. The drilling (and mudding/casing behind the bit) goes down in a flexible pipe. Moreover, the big-rig is often mostly for production (first steps of refining, storage and transport to shore), with smaller drilling platforms around.
On semi-submersible rigs, the whole damn thing floats if the air bladders are inflated. The rig is then anchored to the seafloor out from the platform. The tension in these lines keeps it upright. Living quarters below decks. These cranes appear to be for construction, but the rig will have a couple. When they need more of anything that they aren't going to helicopter out (crew and emergency parts), a ship comes by and you use cranes to offload.
Any word from Petronius platform (not awfully far from Thunder Horse)? I assume it doesn't look too bad as it hasn't been on the AP wire.

The Atlantic/Caribbean wave alley is now in full swing. Going to be a long season. My country of origin, Jamaica is smack in the middle of the paths. There may be nothing left at the end of this season there. This is the fourth hurricane that threatens that vicinity in less than a year. Gulf production is going to take a serious hit if the season continues how it started. We better hope for the best in this regard.

Can not find anything on Petronius, so I guess its ok. Don't have link for the below quote.
$this->bbcode_second_pass_quote('', 'L')LOYDS LISJuly 13, 2005 Battle to save BP's Thunder Horse
BP FACES a potential disaster after its Thunder Horse floating production platform (right) was damaged by Hurricane Dennis when it crashed through the Gulf of Mexico, writes Martyn Wingrove. The semi-submersible platform, located 150 miles southeast of New Orleans, was yesterday listing more than 20°.
BP was frantically working to save the platform before it sinks below the water, thereby delaying a $1bn deepwater oil project for three years or more. 'We don't know yet what made it list and our focus is to stabilise and right the platform,' a BP spokesman said.

'We have deployed remotely operated vehicles with cameras to inspect the submerged portion and are looking for damage. We are also preparing a team to go aboard to look at how to level the platform.' He said the listing could be due to excess water in the platform's ballast tanks and not the result of major structural damage, but no results were available yet from the survey. The MMS said Hurricane Dennis caused 43.8% of the region's 819 manned platforms to be evacuated, while 96% of the Gulf of Mexico's 1.5m barrels daily oil production was shut in.

Thinking about tropical storm season: any thoughts about our stretched infrastructure (98% refinery utilization) with regard to imports. I know that our Arabian imports largely come to the "LOOP" (Louisiana Offshore Oil Port). There are very few places the largest-of-the-large oil tankers can onload or offload directly. Generally, it's Dharan or Bahrain, to LOOP, and back again. Barring a good offshore port, the biggest tankers must transfer oil to ships with less draft which can get in to port.

The thought is, even without a hurricane damaging the LOOP, the shutdowns for storms and the days when ships are avoiding weather would seem to adversely affect our import capacity. Nothing came into LOOP for a couple days because of Dennis, though the terminal kept crude flowing from on-shore reserves.

I'm curious if we'll see this reflected in tomorrow's EIA numbers (which are reflected in tomorrow's NYMEX, and Thursday's corner gas bar).

$this->bbcode_second_pass_quote('', 'T')he Globe and Mail Reuter International By BUSINESS TICKER: NORTH AMERICA: RESOURCES: OIL AND GAS Hurricane Dennis damages BP rig in Gulf of Mexico BP PLC's Thunder Horse platform -- the brightest short-term prospect for raising U.S. oil production -- is tilting 20 to 30 degrees after hurricane Dennis hit the Gulf of Mexico, but the company said it's too early to tell whether initial output will be delayed. BP spokesman Ronnie Chappell said a 10-tonne winch that fell off the platform as it was being evacuated ahead of hurricane Dennis last Thursday probably did not cause the tilt. The $1-billion (U.S.) platform had been expected eventually to boost U.S. Gulf of Mexico oil output by nearly 17 per cent. Thunder Horse's peak output was expected to be 250,000 barrels per day of oil and 200 million cubic feet of natural gas. It is the biggest hope for a small recovery in crude production in the United States, where oil output has been falling since the 1970s. The Gulf currently produces about 1.5 million barrels a day of oil, about 25 per cent of total U.S. output. BP (LSE) fell 14.5 pence (31 cents) to £6.195. Reuters


Who knocked over the 10 ton winch on the way out? :shock:
