Another North Sea disaster
With some 50 serious injuries a year (up by 20) and over 400 reported dangerous occurrences 85 of which were losses of containment of hydrocarbons into the atmosphere (1) it seems an inappropriate time to reduce regulation. Apart from the recent oil spill on Gannet where Shell accept a causal factor may have been lack of maintenance and inspection, with the HSE stating publicly that lack of maintenance offshore could have severe consequences generally across the oilfield, it seems that better and more proactive oversight of this industry is needed rather than less.
(1) Based on public domain data from HSE for year 2009/10, this year figs not yet available, dangerous occurrence is by Government definition under the relevant legislation.
With 50 % of offshore installations well past their original design life (normally 25 years) with some by as much as 20 years, failure is endemic due to ageing, what we call age related failure. The failure mechanisms effect all aspects of the installation where carbon steel is used from the primary structure to pipe, grating, floors, decks et al the list goes on. The corrosion grows and spreads, perniciously like a cancer, through the whole rig, in what is a relatively warm but highly saline atmosphere causing the surface corrosion of metal allied in pipelines with internal erosion caused by reservoir sands carried to the surface by the flow of oil and gas.
Assets which go beyond their design life need more expenditure on maintenance, not less. And, beyond the design life, sometimes called operating or useful life, the risks of continued operation increase with time.
Just at the time when costs are rising revenue is in sharp decline as the reservoirs deplete.

After digital certificate hack, Mozilla seeks reassurances | Free Blog ...
In emails sent out to digital certificate authorities Thursday, Mozilla Certificate Authority (CA) Certificates Module owner Kathleen Wilson asked CAs such as Symantec and Go Daddy to audit their systems for any possible compromise, confirm that nobody can issue a digital certificate without two-factor authentication, and shore up practices with any third parties that might be able to issue digital certificates using the CA’s root key.
Mozilla is giving CAs until Sept. 16 to respond to the email, but the browser maker is not saying what will happen if any of its 54 CAs ignore the request.
Mozilla is also telling the CAs to put “automatic blocks in place for high-profile domain names (including those targeted in the DigiNotar and Comodo attacks this year),” Wilson wrote in the email, which was posted to a Mozilla security discussion forum Thursday morning, Pacific time. “Please further confirm your process for manually verifying such requests, when blocked,” she wrote.
By asking for a manual verification, Mozilla is trying to make it harder for anyone to issue a digital certificate for Google.com or Facebook.com, two domains that were targeted in the DigiNotar hack. Whoever pulled off that attack helped someone execute a massive man-in-the-middle attack that may have compromised security for as many as 300,000 Iranian Internet users.
Companies such as DigiNotar issue digital certificates that tell browsers and other Internet programs that the servers that they are dealing with are legitimate — the real Google.com website, and not some phishing site, for example. If hackers can steal digital certificates and somehow also mess with their victim’s network to redirect to fake sites, the attackers can create virtually undetectable phishing attacks.
In the case of the DigiNotar hack, security experts believe that this technique was used to break into Gmail accounts.
This week, the hacker who earlier in the year broke into Comodo, another CA, took credit for the DigiNotar hack and said he’d compromised four other CAs, including GlobalSign. GlobalSign immediately stopped issuing digital certificates and began a security audit.
