Piper Alpha: Living with the legacy
5 July 2013 Last updated at 12:36 BST
The 25th anniversary of the Piper Alpha disaster, which claimed the lives of 167 men, will be marked on Saturday.
A series of explosions ripped through the North Sea platform, which was destroyed in just 22 minutes.
In the second of two special reports, BBC Scotland's Kevin Keane has been looking at what has changed in the offshore industry as a result of the disaster.
He has also been speaking to some of those who have had to live with its legacy. You may find some testimonies upsetting.
