The 25th anniversary of the Piper Alpha disaster, which claimed the lives of 167 people, has been remembered at a ceremony in Scotland.
The North Sea platform was engulfed in a ball of flames after a gas leak ignited on July 6, 1988.
Hundreds of people today attended a commemoration service in Aberdeen in memory of those who died.
They were joined by politicians, senior figures from the UK oil and gas industry and representatives from the Pound for Piper Trust.
Lessons are being learned to make sure an offshore disaster never happens again, the Secretary of State for Scotland Michael Moore said to mark the 25th anniversary of the Piper Alpha disaster.
Mr Moore said: "It is important that we never forget those who have lost their lives in our oil and gas industry. 25 years on from Piper Alpha, the loss of 167 lives is something that families and communities across the whole country are still coming to terms with".
Safety improvements in the offshore industry are a "lasting memorial" to the 167 people killed in the Piper Alpha disaster, the Prime Minister has said.
In a letter to Malcolm Webb, chief executive of industry group Oil & Gas UK, David Cameron said:
In this testing environment the highest safety standards are paramount. I know how tirelessly the industry works to prevent incidents like Piper Alpha from ever happening again.
Over the last 25 years the North Sea has embraced continuous improvement in health and safety - an appropriate lasting memorial to those who suffered so terribly a quarter of a century ago.
We will never forget the 167 who lost their lives on 6th July 1988. And my thoughts as Aberdeen remembers its loss are with their families and loved ones, the survivors and all those involved on that tragic night.
The names of all 167 people who died in the disaster will be read by representatives from the oil and gas industry and floral wreaths will be laid at the memorial.
Roy Carey, 70, from Ayrshire, was one of 62 survivors and will be attending the service. "It gives me a chance to reflect on it. I do feel it's the only place where I feel a little closer to the lads that never made it," he said.
"A rig can now only burn the fuel that is on board which was not the case on the Piper Alpha. This should prevent a disaster to that extent happening again, but because that is happening in the North Sea doesn't mean it is happening worldwide but it really should be,"
"Safety, with science, should get better not worse and I'm hoping that improvements will be ongoing all the time".
The 25th anniversary of the world's worst offshore disaster, in which 167 men were killed, is being remembered today.
The North Sea tragedy happened on July 6 1988, when explosions and a fireball ripped through the Piper Alpha oil rig.
The service, due to take place at 11am at the North Sea Memorial in Aberdeen's Hazelhead Garden, will begin after the flypast of an RAF Sea King helicopter from Lossiemouth. This was the first aircraft to arrive at the scene of the disaster 25 years ago.
WWF Scotland has called for an investigation into an oil rig in the North Sea, after workers were evacuated for the second time this year, following the discovery of a leak.
In a statement the organisation said that "serious questions must be asked about the integrity of this ageing rig".

In the interests of the environment and all oil workers it would be wise for the relevant authorities to take a much closer look at this platform, and those of a similar age dotted throughout the North Sea.
71 workers have been evacuated from an oil platform in the North Sea after a leak was discovered during maintenance work.
The operator TAQA Bratani said that non-essential staff were taken off the Cormorant Alpha platform as a precaution and that the leak has now been contained.
This is the second time this year that staff have been evacuated from the platform following the discovery of a leak.

The hydrocarbons discovered at 0940 today during maintenance work have now been flushed through with sea water. The platform and all pipeline infrastructure remains shut down as a precaution. The release was contained within the leg and no hydrocarbons were released into the environment.
