In an era of uncertainty, incident investigation services provide a vital source of reassurance. Accidents and incidents can have far-reaching consequences on human life, the environment, and facility operations, emphasising the need for thorough investigation. By adopting a proactive approach to incident investigation, the probability of accidents can be significantly reduced, fostering a safer work environment, and enhancing operational efficiency.

Accident and incident investigation, when implemented effectively, serves as a preventive mechanism, mitigating risks before they escalate into substantial hazards. However, to realise the full potential of such investigations, organisations must prioritise accuracy, detail, and a commitment to implementing the lessons learned.

Leveraging Phast for effective incident investigations and preventive strategy development

DNV's Phast software is a vital tool for incident investigation. It is used by safety professionals to evaluate the release of hazardous materials and assess their potential impact. This valuable information facilitates the identification of root causes of incidents and enables the development of effective preventive measures for future incidents. 

With Phast, users can input key incident details, such as release characteristics, facility layout, and meteorological factors, to accurately model and visualise the dispersion of released substance. Phast offers a wide range of equipment and scenario options, allowing users to simulate various incidents, whether it is a leak from a long pipeline or a catastrophic pressure vessel rupture. The advanced capabilities of Phast ensure comprehensive modelling for different scenarios.

The software generates reliable predictions of the release behaviour, allowing safety professionals to assess the potential consequences, draw conclusions from the simulation results, develop strategies to prevent similar future incidents and make informed decisions regarding mitigation strategies, emergency response plans, and overall safety measures.

Safety professionals can further enhance their understanding of the incident by visualising the impact of the release to the three-dimensional surroundings, such as obstructions, along with wind direction and speed. Phast, including its powerful Phast CFD pool fire and jet fire extensions*, can help with this.

Phast serves as an invaluable tool for aiding accident and incident management within organisations. Its predictive and analytical capabilities provide insights into the possible outcomes of an incident, which subsequently facilitates the pinpointing of root causes. Furthermore, it assists in developing efficient strategies to prevent similar occurrences in the future.
