GRaphical Interface for reliability Forecasting
From 31 March to 2 April 2026, OTC Asia brought together offshore and energy stakeholders in Kuala Lumpur to exchange on current technical and industrial challenges facing the sector. With more than 25,000 participants, 6,600 organizations and representatives from nearly 90 countries, the conference is one of the major international events dedicated to offshore and energy systems.
GRIF contributed to these exchanges around topics related to dependability, safety and reliability, addressing both existing offshore installations and emerging energy applications, in a context where modelling, data and digital tools play an increasingly central role in engineering decisions.
An Event Focused on Concrete Challenges
Key themes at OTC Asia 2026 included decarbonization, digitalization, and integrated offshore operations. Across technical sessions, the conference highlighted how modelling approaches and data‑driven tools are used to support asset performance, risk control and long‑term system resilience, particularly for complex and safety‑critical systems.
The exhibition area reinforced these discussions by encouraging direct technical dialogue between operators, partners and solution providers; fostering exchanges grounded in concrete industrial use cases.
Extending ISO/TR 12489 to Hydrogen Applications
One of the key technical contributions at OTC Asia 2026 was the presentation of the paper "How International Organization for Standardization Intends to Address Low Carbon Energy Specificities for Reliability Modeling and Safety System Calculation", authored by Maïder Estécahandy and Nicolas Clavé. This paper highlights the ongoing revision of the ISO/TR 12489 framework to address the unique safety challenges of emerging low-carbon technologies, particularly hydrogen systems.
Hydrogen presents specific hazards, such as a wide flammability range, high diffusivity, and the potential for violent explosions that demand highly reliable Safety Instrumented Systems (SIS). The presentation demonstrated how applying advanced probabilistic calculations and reliability modeling approaches, ranging from analytical formulas to dynamic methods like Markov models and Petri nets, is critical for evaluating these systems.
The paper illustrated a practical case study using the GRIF software suite to model a hydrogen safety loop. The study proved that utilizing robust field data alongside appropriate mathematical techniques (such as Fault Trees, Reliability Block Diagrams, and Petri nets, all available within GRIF) generates highly accurate reliability indicators. This methodology enables engineers to calculate realistic performance indicators, avoiding the overly conservative estimates of standard formulas.
Presented in an international technical forum such as OTC Asia, this work underscores the growing need for robust, recognized methodologies and certified software tools to ensure the integrity of critical safety barriers in the future of responsible energy development.
International Exposure and Technical Discussions
Participation in OTC Asia 2026 helped reinforce GRIF’s international visibility, supported by the involvement of TotalEnergies EP Malaysia and the quality of the technical exchanges held during the event.
Beyond visibility, the conference provided opportunities to engage with local teams and partners and to take part in discussions centered on the industrial use of reliability and safety methods, notably how these approaches support concrete engineering choices and operational decision‑making for complex systems.
OTC Asia 2026 highlighted the importance of linking technical discussions to industrial practice. Through standards work, technical exchanges and feedback from the field, GRIF remains part of this ongoing effort to support responsible energy development in Asia and beyond.
