13 dead over 40 yrs period in the oilfield, 12 offshore, 1 onshore. Personally knew 8 of them. Equipment failures, cranes, popped ropes, falls, burns, crushed and personal/personnel fk'ups via shortcuts. Life can be so fragile. Pays to handle with care and pays to pay attention. Doing multiple RCAs (root cause analysis)on these things is no fun especially when you know them.
But things have much improved by lessons learned the hard way.
