What We Can Learn From the 100 Largest Losses

What We Can Learn From the 100 Largest Losses

Recently, Marsh released its report on the 100 Largest Losses in the hydrocarbon extraction, transport and processing industry from 1974 to 2013. Using the Nelson-Farrar Petroleum Pant Cost Index, the report includes inflated values to show how much these 100 incidents would cost in 2013.

Of the top 20 events, eight have taken place in the United States. Most of those losses are associated with vapor cloud explosions at petrochemical plants. While the study covers 40 years of plant operations, these events are hardly in our past. A petrochemical explosion on June 13th, 2013 was one of the eight events.

While different sectors were involved in the report, all problems can be narrowed down to a few key areas that exist in all plants: Hardware, Management Systems and Emergency Controls. These are the systems that keep everything running smoothly and their failure can be catastrophic.

One of the easiest ways to ensure your safety systems are always running is to have a maintenance plan in place for routine checkups. The more regular the maintenance, the more you reduce the risk of a catastrophic event. In addition, new and emerging threats should be considered when upgrading hardware and emergency controls. This is why cyber security has been such a huge topic of late. Explosions and natural disasters may be at the heart of these 100 losses, but negligence towards emerging threats leaves the door open to something new creating even more damage.

Critical Measurements in a Process Plant

Critical Measurements in a Process Plant

Measurement is often part of the intelligent HMI discussion from the process industry to boiler systems; the measurement and balance of all materials involved is essential. The list of measurable elements in a plant can seem endless, which begs the question; what measurements should you prioritize in order to have the most efficient process?

This question was posed to Marc L. Hunter, our Vice-President, the other day, to which he replied, “That’s not quite the right question to ask.”

He went on to explain that measurement of anything is dependent on two questions. What is going to happen and what should I pay attention to?

The multitude of factors acting in a plant is indicative of the many different activities being performed. Many of these processes can be easily managed by automation and machines. The most important measurement of a plant then becomes alarms.

Alarm management is vital and should be made as proactive as possible. This requires strategic prioritization of alarms. No alarm should be completely ignored, but a smoothly running system must alert engineers to the most pressing alarms first.

Measurement in a plant therefore boils down to ISA 18.2 Alarm Management Standards. A system made to meet these standards alerts plant engineers of any issue using a prioritized list of alarms. This organization allows for the easy identification of the most critical issues. On days where few high risk problems occur, the less important alarms can be dealt with.

How many priority levels you need to adequately measure the performance of your plant requires a detailed discussion with an engineering consultant with alarm management expertise. The alarm management market offers a substantial variety in terms of the number of priorities levels. There isn’t much of a limit to the number of priority levels you can have. An alarm management expert will help you define just what you need to meet your business goals.
