DIVERS working on North Sea gas rigs joined millions of people in last night’s weekly “thank you” to the NHS and care workers – from more than 300 feet below the surface.

The divers, based on the maintenance vessel Rever Polaris, carry out dangerous underwater maintenance work on rigs in the Jura gas field 100 miles east of the Shetland Islands and 275 miles north-east of Aberdeen.

Today they displayed a poster carrying the message: “Thank you to the NHS from the Rever Polaris, depth 110m (330ft).”
