The conference marked the anniversary of the Piper Alpha disaster, which Lord Cullen investigated on behalf of the government. The recommendations made in his landmark report reshaped offshore safety culture THERE is much to be learnt from the reasons for major accidents, by which I mean the underlying factors in particular.
Piper Alpha Incident During the platform fire invirtually nothing went right, which allows us to draw lessons from a long list of events leading to the hazard.
In the aftermath of the huge fire on the Piper Alpha platform, July 6,it was clear that the fire started and escalated very quickly into a full-blown disaster due to a huge list of individual failures at every level of the process safety management systems.
In many respects, virtually nothing in the safety process worked as it should have, and the result was fatalities out of the men on the platform, plus two more men on a rescue vessel.
Property damage ultimately totaled several billion dollars. Part of the problem of trying to examine this event is its complexity. The specific series of events that turned a process safety incident into a disaster began with a decision to change the mode of production on the platform. Operators were also inexperienced with this production method.
The most basic process safety management concepts did not exist on the platform. The platform was poorly designed from a safety management standpoint.
The match probably could have been struck in many places and times with similar results. Consider what happened after the first explosion: Loss of electric power was almost immediate, and along with it public address, general alarms, emergency lighting, emergency shutdown capability, and fire protection systems.
The offshore installation manager panicked and did not order evacuation soon enough, although evacuation paths were already largely blocked due to the layout of the living quarters and the lifeboats were inaccessible.
The layout of the platform combined with inadequate blast panels and firewalls allowed the fire to escalate rapidly.
The second explosion occurred within about two minutes of the first.

Reviewing a detailed sequence of events well worth doing provides insight into the process safety indicators. Many factors combined to create multiple holes through every layer of protection creating a process safety incident: Management driving production beyond safe levels Operators insufficiently trained Lack of experienced supervisors on the platform Poor maintenance practices Little use of redundancy for critical systems Loss of power caused safety systems to shut down Critical systems not physically protected Inaccessibility of safety and escape equipment for personnel, and Dangerous materials located near crew quarters.
This is the beginning of the list and in subsequent posts we will examine some of the human factors and maintenance issues in greater detail. The decision to change the platform to the alternate production method Phase 1 rather than the normal Phase 2 with its higher pressures was one of expedience.
Gas driers that were normally used were shut down for maintenance, and this shift allowed the platform to continue producing. The platforms in the group Piper Alpha, Tartan, Claymore and MCP were interconnected physically but management was not necessarily well coordinated.
Small leaks increased, piping would probably vibrate and rattle, and there was apparently a report that at least one of the flares was roaring and was much larger.There are some truths that I strive to preach, for lack of a better word, in today's information-culture wars propagated in our corrupt mainstream media.
Piper Bravo is one of the the most modern rigs in the North Sea. It incorporates safety features recommended in the Cullen report into the Piper Alpha disaster. Lord Cullen of Whitekirk gave this speech at the opening of Oil & Gas UK’s Safety 30 conference in Aberdeen on 5 June.
The conference marked the anniversary of the Piper Alpha disaster, which Lord Cullen investigated on behalf of the government. The recommendations made in his landmark report reshaped offshore safety culture. Piper Alpha: Lessons Learnt, Piper Alpha was a large North Sea oil platform that started production in It produced oil from 24 wells and in its early life it had also produced gas from two wells.
