International Software Summit 2025 - Kuala Lumpur

Phast, Safeti, KFX and EXSIM 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, and the latest developments in KFX/EXSIM. These advancements support more accurate, reliable, and comprehensive safety risk analyses to meet evolving industry needs.

CCS is advancing rapidly, with over 500 projects underway globally. This presentation addresses safety considerations for managing large quantity of CO2 and showcases advanced dispersion modelling techniques for both atmospheric and subsea releases to support safe CCS projects.

Phast, the industry-standard consequence modelling software, is trusted by over 1,000 companies worldwide. For over 40 years, its models have been rigorously validated through large-scale testing at DNV’s Spadeadam site. This presentation highlights validation efforts for hydrocarbons, hydrogen, CO2, and more, ensuring accuracy and reliability across applications.

As the maritime industry explores alternative fuels, ammonia is gaining attention as a potential zero-carbon shipping fuel. However, its toxicity and volatility present significant safety challenges, particularly during bunkering operations. This study assesses the dispersion and dissipation characteristics of ammonia in the event of accidental releases during bunkering, using 2D simulations in DNV Phast 9.0. Key factors, including release size, operating conditions, and meteorological parameters, are analyzed to determine their influence on ammonia cloud behavior. The results highlight the critical role of wind conditions in dispersion dynamics, demonstrating that lower wind speeds prolong dissipation and increase exposure distances, whereas higher wind speeds accelerate dilution. Under certain conditions, ammonia concentrations remain above regulatory safety thresholds for extended durations, underscoring the need for robust emergency response strategies. This study provides key insights for improving safety measures, including real-time monitoring, early leak detection, and enhanced regulatory compliance, ultimately supporting the safe adoption of ammonia as a marine fuel, contributing to the safe and sustainable adoption of ammonia as a marine fuel.

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.

Ammonia is a key hydrogen carrier and alternative marine fuel, but its toxicity presents safety challenges. This presentation outlines recommended methodologies for accurate ammonia dispersion modelling and mitigation using water curtains, based on findings from DNV’s latest ammonia Joint Industry Project (JIP) with industry partners.

With the rise of hydrogen, ammonia, and CCS projects, performance forecasting and RAM analysis are becoming increasingly vital. DNV’s Maros and Taro software, proven in oil and gas, now support these sectors by optimizing CAPEX/OPEX, improving availability, and enhancing decision-making across the asset lifecycle - from design to decommissioning.

This paper presents a reliability analysis of decarbonization within Power Management Systems. With the growing emphasis on sustainability and environmental concerns,  decarbonization efforts have become paramount across various industries. The study employs advanced reliability analysis techniques to assess 3 cases on effectiveness and performance of decarbonization strategies, aiming to enhance operational efficiency while reducing carbon emissions. The study highlights challenges, proposes mitigation strategies, and provides insights to guide stakeholders in enhancing efficiency, reducing emissions, and advancing sustainability goals. 

What's coming in 2026.

This session demonstrates how DNV’s MAROS software was applied to perform a Reliability, Availability, and Maintainability (RAM) study for a large-scale green hydrogen facility. The talk covers modeling approach, key assumptions, and insights on optimizing design for production availability, showcasing MAROS as a powerful tool for complex energy projects.

Navigate the latest enhancements in Maros 10.01 with the product manager.

This session explores the critical role of Permit to Work (PTW) systems in managing high-risk operations across high-hazard industries such as oil & gas, chemicals, hydrogen, and energy sectors. It will examine how PTW frameworks contribute to strengthening operational barriers, preventing incidents, and ensuring compliance. The session highlights the transition from traditional paper-based PTW processes to digital solutions, showcasing how digital platforms enhance real-time visibility, work control, accountability, and safety performance. Key benefits of electronic PTW (e-PTW) systems—such as audit trails, contractor integration, and real-time status updates—will be discussed, along with integration capabilities with Synergi Life and broader HSE reporting systems. A real-world use case from S-Oil Korea’s onshore plant turnaround will illustrate the practical application, challenges, and success factors in implementing digital PTW as part of a holistic safety management strategy.
