The oil industry will have to overhaul how it operates in deep water as a result of the Gulf of Mexico disaster, BP’s chief executive, Tony Hayward, said last night, as the company disclosed that the cost of the spill had now reached $350m (£236m).
He said there would be "significant implications" in terms of new regulations and safety, while companies drilling offshore may be required in future to have spill-response equipment on standby.
The blowout preventer, which failed to stem the flow of oil when the wellhead erupted and is widely used throughout the industry, is likely to be declared not fit for purpose, he added.
Hayward admitted BP was having to learn on the job how to contain the spill as this kind of accident had never happened before at such depths. "There is an enormous amount of learning going on. We are doing it for real for the first time," he told reporters on a conference call last night.
He also acknowledged that BP did not know how much oil was leaking from the stricken pipeline, which now lies 1.5km under the sea after the rig operating it exploded and sank three weeks ago.
Kent Wells, senior vice-president in BP’s exploration and production business, said: "There is no way to measure it [the flow]." A BP spokesman stressed the estimate of 5,000 barrels a day leaking from the well came from the US National Oceanic and Atmospheric Administration.
US regulators and government agencies are still investigating what caused the well head to blow, leading to the disaster in which 11 rig workers died.
Hayward said: "Implications for the industry will only become clear once the results of the investigation become known." But he added: "There will be significant implications for regulations, on the redundancy of blowout preventers, and safety. There will be some significant findings on subsea intervention [how leaks are tackled] – what might industry have to have available [in case any accident happened]."
The cost of dealing with the disaster includes the flotilla of 275 skimmers, tugs, barges and recovery vessels being used to collect and disperse the slick, as well as the efforts to stem the spill on the sea bed. The clean-up has cost about $150m so far and has escalated significantly as the scale of the environmental disaster has unfolded.
A few days after the Deepwater Horizon exploded, BP said about $1m a day was being spent on the relief effort. Last week, this rose to $6m a day, and now stands at approximately $10m. Drilling several relief wells will also cost a further $100m. Another $100m has been spent distributing grants to the four US states affected by the slick – Louisiana, Florida, Alabama and Mississippi. Unspecified amounts have also been paid to the National Guard and in federal costs.
BP said it was also planning to use "top kill" to try to stem the flow of oil from the well head. This involves blasting a mixture of debris such as rubber tyres and golf balls into the blowout preventer, which would then be sealed using cement. A spokesman for the company said it could take several weeks to prepare.
The company is also planning to lower a second, much smaller canopy on to one of the two remaining leaks on the pipe, which is now lying on the seabed.
