After the Piper Alpha disaster, we got decender things offshore which I can't remember the name of.
That was an emergency abseiling kit designed to be idiot proof. I cannot remember it being used in anger.
I was involved after the Piper Alpha being on the primary support helicopter. During the following morning I had to take the off duty OIM (Offshore Installation Manager) plus others on a recce of the platform whilst it was still burning to get a close up of what was burning and where. Later in the day the same with Red Adair an others.
The pictures taken at that time by Time Magazine and others were from my aircraft.
