Flights of Super Puma helicopters carrying oil and gas workers to North Sea installations resumed this week.
Last month, use of the aircraft was suspended after the crash of a Super Puma off Shetland left four dead.
On Tuesday, UK Chancellor George Osborne flew offshore in a Super Puma AS332 Ls.
Speaking earlier at the Offshore Europe 2013 conference in Aberdeen, he paid tribute to those killed in the crash and to all oil and gas workers.
“Our thoughts are with their families, friends and colleagues at this difficult time – and the book of condolences here today shows the depth of feeling for those four brave professionals,” he said.
“And we should also remember that 25 years ago, 167 people lost their lives in the Piper Alpha disaster. The whole of the UK owes a massive debt to the thousands of men and women who work in what is an inherently dangerous environment – delivering enormous benefits to every family in the country.”
The Super Puma L2 that crashed was headed to Shetland’s Sumburgh Airport from the Borgsten Dolphin rig.
