UK government energy minister Charles Hendry said he had been advised by Total that the flare was "well-above" the level of the gas. | UK government energy minister Charles Hendry said he had been advised by Total that the flare was "well-above" the level of the gas. |
He said: "Clearly, when you have a significant amount of gas escaping, there is a case for trying to burn some of it off to get rid of it rather than leaving it as a hazard elsewhere, so there has to be a decision made on the balance between safe operation and flaring off the gas that can be flared off and closing down the full platform." | He said: "Clearly, when you have a significant amount of gas escaping, there is a case for trying to burn some of it off to get rid of it rather than leaving it as a hazard elsewhere, so there has to be a decision made on the balance between safe operation and flaring off the gas that can be flared off and closing down the full platform." |

Scottish Environment Secretary Richard Lochhead said: "Any gas leak on an evacuated offshore installation is, of course, deeply worrying. | |
"Therefore it's critical both Total and the UK government ensure absolute transparency, with all information placed in the public domain. | |
"This should include not just details on the level of risk, but also how this is calculated." | |
He said the Scottish government was responsible for the marine environment. | |
"The gas condensate is expected to disperse naturally and - as the situation currently stands - environmental risks are minimal," Mr Lochhead said. | |
"However, we're not complacent and are continually reviewing the situation." | |
