A team of 11 has boarded the Elgin platform in the North Sea as preparations continue to stem the leak of gas. Operator Total said it was part of its \"well kill\" plans which are likely to involve plugging the leak with mud. The experts flew out from Aberdeen on Thursday morning. The platform was evacuated after gas started leaking on Sunday 25 March. Tests on fish from close to the gas leak have shown they are \"untainted\". The Scottish government said on Wednesday that taste tests concluded that \"no taint of hydrocarbons\" was found in the samples. Full chemical testing of all environmental samples is continuing.
