Offshore union RMT has made a new call for a full public inquiry into North Sea helicopter safety.

Their move through an emergency motion at the STUC conference comes after 33 people have died in the past decasde in incidents involving Super Puma helicopters in UK and Norwegian sectors of the North Sea. 

The union said such an inquiry is essential due to the "ongoing decline in offshore workers' confidence" in the safety of offshore helicopter operations.

Fourteen oil workers and two crew died when a Bond Super Puma plunged into the water off the Aberdeenshire coast on April 1 2009.

An Air Accidents Investigation Branch (AAIB) probe into the crash found that the aircraft suffered a "catastrophic failure" of its main rotor gearbox, while a fatal accident inquiry (FAI) in 2014 found that the tragedy might have been avoided.

The disaster has already led to a long ban on Super Puma aircraft off Scotland’s shores and a detailed technical investigation.

Last month two opposition MSPs, Labour’s Lewis Macdonald and Liberal Democrat Tavish Scott,  renewed demands for such an inqui

Now in an emergency motion tabled at the conference in Dundee on Wednesday, the RMT said that the FAI process does not offer "meaningful safety lessons for the wider industry" and is not an effective means of restorative justice for the families affected by offshore helicopter incidents.

RMT general secretary, Mick Cash said: "It is nothing short of a scandal that the Scottish and UK Governments are opposing the public inquiry that is clearly needed to tackle the decline we have seen over the last 10 years in offshore workers' confidence in the safety of the helicopter transport they are required to travel in.

"That is why are calling for renewed support from across the Scottish trade union movement for our on-going campaign in Dundee today.

"Both RMT and Unite support an inquiry, which would cover commercial pressures brought on operators by oil and gas companies and we now have a significant body of cross-party support, including SNP MPs in Westminster, who have added their voices to this important campaign for a just response to the deaths, trauma and growing safety fears of North Sea oil and gas workers and their families."

Eleven passengers and two crew members were killed when a Super Puma 225 aircraft came down near the city of Bergen, Norway, in April 2016 while in August 2013 a Super Puma L2 carrying oil rig workers ditched in the North Sea leaving four people dead.

In a statement after the FAI Bond Offshore said it accepted that it had made mistakes and that lessons have been learned and continue to be learned.

The motion, moved by Aberdeen Trades Union Council, calls on the STUC congress to write to the Scottish Government urging them to back a full independent public inquiry.

The crash in 2009 claimed the lives of captain and co-pilot Paul Burnham, 31, from Methlick in Aberdeenshire, and Mr Menzies, who was from Worcestershire.

Five men from Aberdeen died: Alex Dallas, 62, James Costello, 24, Stuart Wood, 27, Vernon Elrick, 41, and Brian Barkley, 30; and two workers were from Aberdeenshire: Leslie Taylor, 41, from Kintore, and Warren Mitchell, 38, from Oldmeldrum.

The other victims were Raymond Doyle, 57, from Cumbernauld; David Rae, 63, from Dumfries; Gareth Hughes, 53, from Angus; Nairn Ferrier, 40, from Dundee; James Edwards, 33, from Liverpool; Nolan Goble, 34, from Norwich; and Mihails Zuravskis, 39, from Latvia.
