OFFSHORE union RMT has repeated its call for a full public inquiry into North Sea helicopter safety – exactly 10 years on from the Super Puma tragedy.

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.

RMT is calling for lasting changes to regulatory standards to make the industry safer in the wake of a series of tragedies in recent years.

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.

RMT general secretary Mick Cash said: “On the 10th anniversary of the Super Puma disaster off Peterhead that cost 16 workers their lives our thoughts are with the families, colleagues and friends affected by the tragedy. Offshore workers remain angry that despite a five-year fatal accident inquiry process we still await justice, meaningful changes and the public inquiry into helicopter safety in the North Sea that has long been our central demand.

“Meanwhile confidence in the safety of offshore helicopter transport has declined as we continue to see commercial pressures on standards in a culture of cost-cutting.

“On this grim anniversary for the industry the union pledges to step up the fight for North Sea helicopter safety, a public inquiry and lasting changes to regulatory standards that are the best way to restore offshore workers’ confidence.”

The crash in 2009 claimed the lives of captain and co-pilot Paul Burnham, 31, from Methlick in Aberdeenshire, and Richard Menzies, 24, from Droitwich Spa in 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.

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.

A Department for Transport spokesman said: “We have given this matter careful and serious consideration, and the CAA has already undertaken a comprehensive review into this matter.

“We found that a public inquiry would not achieve anything beyond the assurances already provided by this review, which culminated in number of significant changes to increase the safety standards of offshore helicopter flights.”

Paul Wheelhouse MSP, Minister for Energy, Connectivity and the Islands, said the offshore workforce’s concerns on helicopter safety are a “shared priority of the highest order” and added his thoughts were with the families and friends of those who died in the accident.

He added: “While we have no legal or regulatory powers in respect of aviation safety, we have made clear to our industry partners that nothing is more important than ensuring the safety of those who work offshore.

“We are very sympathetic to the underlying concerns of the offshore workforce, and have raised specific issues with employers on their behalf.

“However, we do not believe a public inquiry into helicopter safety would, at this time, add to the significant streams of work being undertaken by the Civil Aviation Authority, unions, operators and other stakeholders in developing and implementing a range of safety measures to address concerns that have been raised.”

Deirdre Michie, chief executive of Oil and Gas UK, said: “As we mark the 10th anniversary of the tragic Super Puma helicopter crash in the North Sea, our thoughts remain with the families, friends and colleagues who lost loved ones that day and we will never forget them.

“This anniversary serves as a stark reminder that we can never be complacent about ensuring safe operations in our industry.”
