Q: I’ve received a number of questions about the oil drilling accident in the Gulf of Mexico: What caused it? If properly designed process control systems were used, could the blowout have been prevented? What contributions could process control have made to stop the flow after the blowout?

A: To answer these questions, we must understand the drilling process, the causes of the BP accident and the kinds of automatic controls necessary for both the normal and the emergency drilling operation.

Drilling a test well on land is as simple as digging a hole. Drilling deep under the sea increases both the risks and the costs because of the high pressures and hostile environment at the ocean bottom. As the depth increases, the weight of the connecting piping between the sea floor and the platform above also increases. To reduce this weight and the associated cost, the pipe thicknesses had to be reduced, which could only be achieved if some of the drilling equipment was lowered down to the ocean floor where the pressure is high (2200 PSI in case of BP), the temperature is near freezing, and the environment is corrosive. Furthermore, the lowered equipment is inaccessible and has to be operated by remote-operated vehicles (ROV) or subsea robots.

Under these conditions, state-of-the-art technology, including automatic safety controls, trips and redundant equipment, should have been used, potentially making the drilling of deep sea wells uneconomical and in some cases consuming more energy than the wells produced. The industry and its regulator, the Mineral Management Service, in the absence of standards requiring such controls, concentrated on cutting costs.

After 12h I have received an email from the website owner , Mr. Richard – the so called “code-director” (hahaha) telling me that he was unable to find a proper unlock code for my BB 8900 but I can choose another option from their website, and so on. Practically just bullshit …

Hi ,

This is just to inform you that a request on the server for your BlackBerry phones unlock code (imei : 359485027368XXX ) has returned “Code Not Found”

This could be because your imei is incorrect. Please recheck your imei and if incorrect forward to us for resubmission.(free)

This could also mean that the unlock service chosen wasnt the service that locked your phone.

YOU MAY have an alternative service….

For example if you chose Motorola unlock codes we try to obtain your codes from Motorola, if your phone returned Code Not Found from them it could be that your “network” that locked it, ie Vodafone or AT&T.  Its quite possible and happens quite often that if you re-place your order choosing the alternative service you can obtain your codes this way.  Alternatives are not always available it really will depend on your network and make of phone, you can check our list here:

When you order codes from us our form just automatically selects the CHEAPEST option available, not always the most reliable for your phone, If you would like to try another service please REPLY and I can set up new payment for another code.

I have submitted a refund request two or three times, no answer. I had to contact Paypal report it and after a couple of days PayPal refunded my account.

So please take care when you’re looking for “unlock blackberry” on Google, a lot of scammers like this one ( foneszone.co.uk ) show up. It’s better to be warned than sorry !

Such is the case with the Sony E-Series Walkman, a flash player positioned to square off against the iPod Nano.

Available in 4 , 8 and 16 GB versions depending on your pocked size , the Sony Walkman E series is a good competitor for Apple’s Ipod. The sound quality is excellent and you don’t need iTunes to upload your .mp3 files to your Walkman. The device is automatically recognized by WinXP and Vista , and all you have to do is copy/paste or drag&drop your favourite music , videos , photos to the specified folders with the same name.

Battery is awesome, you can keep it in standby for more than a week and while you’re listening to music be shure that 12hours you will not have any issues with it. The 4GB version costs in Romania about 100 US Dollars and the 16 GB version around 230 US Dollars.
