Successful plugging of two Gannet Alpha leaks come as a Scottish newspaper reveals Shell's poor safety record in the region
The oil sheen on the surface of the North Sea that followed the UK's worst oil spill for a decade has finally disappeared, according to Shell, after the company managed to plug its leaking pipeline on Friday.
Government officials are now launching an investigation into the leak as part of an effort to discover how the spill came about and how to prevent such damage recurring.
Richard Lochhead, the Scottish cabinet secretary for rural affairs and the environment, also called on Shell to review its procedures for handling oil spills, after the company was heavily criticised for being too slow to disclose the leak to the public. Lochhead has written to Chris Huhne, the UK climate and energy secretary, to ask for a meeting on the procedure for communicating incidents.
Shell's successful plugging of both the primary and secondary leaks at the Gannet Alpha platform, 112 miles east of Aberdeen, came as a Scottish newspaper revealed Shell's poor safety record in the region.
An investigation by the Sunday Herald found that Shell had been officially censured 25 times in the past six years for breaking safety rules, giving it one of the worst safety records of any major oil company in the UK. Infringements by Shell include repeatedly failing to maintain pipelines - similar to the one that gave rise to the Gannet leak - as well as for failing to report a dangerous incident, and failing to protect workers from hazardous chemicals. The revelations cited come from records held by the government's Health and Safety Executive (HSE), and include incidents in which Shell was fined or received an official reprimand.
Since 2005, Shell has been prosecuted four times: for an explosion at Bacton gas terminal near Norwich; an accident at Ellesmere Port in Cheshire; a collision at the Mossmorran gas plant in Fife; and a fatality on the Clipper rig in the North Sea. The company has been forced to pay out nearly �1m in fines and legal costs. No other major oil company has faced as many prosecutions in the last six years, according to the HSE. Talisman was prosecuted twice in the period, while BP, Total, Amec and Nexen were each prosecuted once, the Sunday Herald reported.
Shell said: "Safety is our foremost priority at all times. As part of that commitment, in 2004 Shell initiated a $1.2bn (�730m) project to upgrade our assets in the North Sea. This has been completed. This year alone, we plan to invest approximately $600m (�365m) in our assets in the region."
Green campaigners reacted angrily to Shell's record. Stuart Housden, director of RSPB Scotland, said: "Shell is a major player in UK waters. The records show however, that Shell is vulnerable to questioning around its maintenance and investment programme. Senior management must seek exemplar status and invest accordingly to achieve a rapid and lasting improvement."
Stan Blackley, chief executive of Friends of the Earth Scotland, said: "Shell has been found guilty of serial breaches of safety rules, including failing to maintain pipelines and vital equipment properly and failing to avoid or report dangerous practices and occurrences. It's depressing but not a surprise, since Shell already has a reputation among environmental and human rights groups for poor practice, complacency and misinformation. You only have to look at its operations in Nigeria in recent years to see evidence of that."
The Guardian recently revealed that Shell had been responsible for spills in Nigeria far bigger than the BP disaster in the Gulf of Mexico last year.
Blackley said: "Shell's record suggests to us that oil spills and leaks such as the recent one from the Gannet platform will continue to happen unless Shell learns from its mistakes, improves its maintenance regimes, and faces tougher penalties. The levying of a fine or requirement to pay compensation will be shrugged off by such a rich company, and the cost will be passed on to consumers or written off in some way. The executives running the business need to be held accountable for any failings or wrongdoings and, if found guilty of any breach of the law, prosecuted to the full extent of the law."
Shell's safety record is likely to come under scrutiny as the government's investigation into the leak is launched this week. First, Scotland's procurator fiscal will meet experts from the HSE and officials from the Department of Energy and Climate Change (Decc) in order to set the initial scope for the investigation. When Decc has completed the investigation, which will involve talking to divers, marine experts and Shell executives, the results will be taken back to the procurator fiscal who will have to decide whether to proceed with a criminal prosecution.
One of the key questions is whether Shell will have to pay for the government's costs in containing the leak, including the cost of surveillance flights by Marine Scotland.
Shell said that after its divers closed a faulty relief valve on Friday, no further oil had been released. However, the pipeline - which has been secured to the seabed with 26 concrete "mattresses" - could still contain as much as 660 tonnes of oil, three times more than the nearly 220 tonnes that has already leaked. The company is looking at how to make that safe, as well as monitoring the area to ensure that no further oil is seeping out.
Decc has said a containment structure might need to be built in order to ensure that no further oil reaches the sea as the pipeline is dealt with.
Green campaigners criticised Shell for not being sufficiently open about the incident, which was discovered on Wednesday 10 August but not disclosed to the public for two days, and they said the incident raised questions over the safety of oil companies' plans to drill in deep water in the Arctic, as the North Sea is generally supposed to be the safest in the world in terms of spills.
However, a Guardian investigation this summer found that there is an oil leak in the North Sea about once a week on average, though most of them are minor.
A spokesman for HSE said its information on safety breaches at Shell and other oil companies "should not be read as a league table" as it did not take into account the relative size of companies' operations.
He said: "HSE has robust regulatory relationship with all offshore operators and we have an established track record of holding them to account. The offshore safety regulations in the UK already require industry to adopt high standards and additional requirements placed upon operators to undertake audits of their own management systems for managing safety, have third-party independent checks and examination undertaken of safety critical equipment and systems, and to revise and undertake thorough reviews of installation safety cases to ensure they are fit for purpose."
