A massive investment in Shetland's Sullom Voe oil terminal will extend the facility’s life for a further 25 years.

Sixty million pounds is to be spent on the biggest construction project the site has seen since the early 1980s.

At its peak the terminal separated more than 3,000 tonnes of gas every day from the 1.5 million barrels of oil from the North Sea.

Today it handles far less, which means costly maintenance of corroding metal pipes which are no longer needed.

A new plant is part of a £60million investment which will see the liquid petroleum gas used to run the terminals' power station or to be piped out into the North Sea to extract further oil.

The Aurora this month celebrated a milestone having put 100 tonne tower in place.

Sullom Voe Terminal Manager, Lindsay Boswell said: "We started construction in August last year and will complete around August next year. It sets us up for the long term future for Sullom Voe."

The workforce at the terminal will falnol by around 40. But it is hoped more work coming to Shetland from new oil fields will compensate for that.
