Piper Alpha: A Maintenance Process Hazard Analysis

Among the physical causes of the initial process safety incident, maintenance should be at the top of the list. That basic safety management failure struck the first match.

Piper Alpha: Maintaining a safe work environment

Operator and supervisor errors escalated a process safety incident into a disaster. Could people better trained in oil and gas safety procedures have prevented it, or stopped the process safety incident once the fire stated?

The Rocky Relationship between Safety and Security

Best practices for avoiding common cause failure and preventing cyber security attacks in Safety Systems.

Common Denominator of Economic Effect

The common denominators of most major process safety disasters is that they seem to happen in facilities where people are not well trained and they work in units where equipment and systems are not always in the best condition. Much of that is probably cost dr…
