Critical Analysis: Piper Alpha
Introduction:
The Piper Alpha, was an offshore oil production platform that was located in the British sector of the North Sea. It was operated by the Occidental Petroleum Caledonia Ltd. Piper Alpha at the time accounted for approximately ten percent for all gas and oil that was produced from the North Sea (Konard, 2011). Initially Piper Alpha started as an oil platform but later on it was converted to gas production. On the 6th of July 1988, a catastrophic explosion killed 167 men and incinerating the platform causing a damage bill in excess of 3.4 billion U.S dollar. Piper Alpha is the greatest engineering disaster to date. It represent everything that can go wrong due to maintenance errors, causing the worst possible outcome, the loss of many human lives. However, it is essential to understand Piper Alpha disaster was not caused by a singular problem or person, but rather many causes that worked together to create the disaster.
The three main causes, which are not exclusives:
1- Safety Valves maintenance
2- The Firewalls used to construct the four Piper Alpha modules.
3- The rubber matting used by the divers blocked the grating from allowing leaked oil to pass through to the sea.
This analysis is going to focus on the maintenance failures and ignore the rest. It is commendable to note that nothing can be said with absolute certainty because the fire left little for the investigators. The analysis is grounded on few pieces of evidence that were found after two years of investigation. The investigation team was led by Lord Cullen and his report on the incident was published in 1990, it is referred to as the “Cullen Report” or “The public inquiry into the Piper Alpha disaster”.
Summary of the Saf...

...gement team should require the head of maintenance approval.

The filing system flaws were only part of the problem. The other part was the safety procedure conducted by the maintenance team. If the pipe was secured no leak would have happened and therefore the first explosion would have at least been minimised and contained.
The maintenance team should have done the following:
- Follow all safety requirements.
- Annual remainder of all safety requirements through yearly training.
- Maintenance should be conducted in pairs at least even if the task require only one person.
- Maintenance review by the maintenance manager for all tasks.
- Operation tests on short interval should be conducted after every single maintenance to confirm it is safe to operate.
- All maintenance tasks need to be isolated to avoid system operation while there is ongoing maintenance.
