Predicting major hazard accidents by monitoring their barrier systems: A validation in retrospective

OCI Nitrogen, one of Europe's largest fertilizer producers, is investigating the extent to which it is possible to take targeted measures at an early stage and stop the development of major hazard accident processes. An innovative model has been developed and recently explained and elaborated in a number of publications. This current paper...

Predicting major accidents in the process industry based on the barrier status at scenario level: A practical approach

OCI Nitrogen wants to gain knowledge of (leading) indicators regarding the process safety performance of their ammonia production process. This paper answers the question whether indicators can be derived from the barrier system status to provide information about the development and likelihood of the major accident processes in the ammonia...

Predicting major hazard accidents in the process industry based on organizational factors: A practical, qualitative approach

OCI Nitrogen seeks to gain knowledge of (leading) indicators regarding the process safety performance of their ammonia production process. The current sub-study raises the question whether major hazard accidents in the ammonia production process can be predicted from organizational factors, also called management delivery systems. This paper...

Determining a realistic ranking of the most dangerous process equipment of the ammonia production process: A practical approach

OCI Nitrogen seeks to gain knowledge of (leading) indicators regarding the process safety performance of their ammonia production process. The current research determines the most dangerous process equipment by calculating their effects resulting from a loss of containment using DNV GL's Phast™ dispersion model. In this paper, flammable and...

Een praktische aanpak voor het voorspellen van majeure ongevallen in de procesindustrie op basis van de barriere status op scenario niveau

OCI Nitrogen aims to build up knowledge of (leading) indicators that provide insight in advance into the process safety performance of their ammonia production process. Two sub-studies have already been published in TtA. The first sub-study focused on ranking the most dangerous process units of the ammonia production process. In the second sub...

Een praktische, kwalitatieve aanpak voor het voorspellen van majeure ongevallen in de proces- industrie op basis van organisatorische factoren

OCI Nitrogen aims to build up knowledge of (leading, proactive) indicators that provide insight into the process safety performance of the ammonia production process. Three sub-studies have already been published in TtA. The main question of this sub-study is whether major accidents in the ammonia production process can be predicted from...

Mechanical integrity of process installations: Barrier alarm management based on bowties

A Safety Research project was carried out in an ammonia plant of OCI Nitrogen, located at the Chemelot site in Geleen, The Netherlands. This research focused on the development of a method to monitor accident processes in the chemical industry mainly caused by mechanical integrity of static equipment like vessels, tanks and heat exchangers. A...
