Plant Excellence Summit 2026 - Rayong

DNV Energy Transition Outlook (ETO) offers key insights into global energy shifts. This presentation highlights key trends in energy transition, especially hydrocarbons, hydrogen, and CCS and the role of oil and gas companies can play.

This session will discuss Thailand's industrial safety regulations and the application of Risk-Based Inspection (RBI) methodologies for pressure vessels. Participants will gain insights into regulatory expectations, safety management practices, and industry readiness for sustainable plant operations.

Learn how Risk-Based Inspection (RBI) methodologies can be applied to fixed equipment to optimize inspection planning, improve safety, reduce operational risks, and enhance asset integrity throughout the equipment lifecycle.

The main objective of Process Safety Management (PSM) is to prevent the top event of Loss Of Primary Containment (LOPC).

In Bow Tie Analysis model, there are prevention barriers e.g. Emergency Shutdown System (ESD) to prevent LOPC and there also mitigation barriers e.g. automatic fire suppression to stop escalation of LOPC to major accident event (MAE). It is important to ensure that Bow Tie Analysis barriers are always effective. The digital applications and technology can be applied to ensure effectiveness of Bow Tie Analysis barriers (safeguards).

There are many use cases in Refinery and Petrochemical Plants. There is a success case of simple coding by standard Microsoft tools for Barrier Validation by Field Operator. AI agents are used for Stress Corrosion Cracking and Corrosion Under Pipe Support prediction. Drones are widely used for process equipment inspection and firefighting command team.

Phast and Safeti are industry-standard tools for safety and risk analysis for major hazard facilities. This presentation will highlight key updates from the past year and outline our roadmap for the year ahead. Topics include consequence modelling with Phast CFD, transport route model enhancements, IRPA in Safeti, integration of CFD data into QRA, solid explosion modelling, improved pipeline release modelling, etc.. These advancements support more accurate, reliable, and comprehensive safety risk analyses to meet evolving industry needs.

Traditional consequence modelling in QRA typically relies on empirical models with free-field assumptions. While effective in many scenarios, this approach can lead to overestimated or inaccurate results when obstacles, complex terrain, or mitigation measures significantly influence outcomes.
CFD-based consequence modelling addresses these limitations by accurately representing such complexities. By integrating CFD results into Safeti QRA, risk analyses can be made more accurate. This presentation will outline the integration process and illustrate its benefits through a case study.
