Summary: When is 3D CFD required in gas dispersion modelling? 3D CFD isn’t usually named as a legal requirement. UK and Australian rules apply the ALARP principle instead; US rules ask for a documented hazard analysis; Norway’s NORSOK standards build CFD into recognised offshore practice, though they’re industry standards, not statutes. In practice, CFD becomes...Continue Reading

SynergenOG delivered a four-day Quantitative Risk Assessment (QRA) training programme for Pertamina Hulu Indonesia in Balikpapan, Indonesia. The programme was attended by 19 participants from functions including Process Safety and Asset Integrity, Asset Integrity and Reliability, Process Safety Assurance, Health, Safety, Security and Environment, Product Operations, and Surface Facilities Planning and Support. The training provided...Continue Reading

Summary: EERA—Evacuation, Escape and Rescue Analysis—tests whether offshore personnel can respond to a major accident, reach a suitable muster area or Temporary Refuge, and leave or escape the installation with a credible prospect of recovery and rescue. In the UK, PFEER regulation 5 requires this assessment and measurable performance standards for each credible scenario. It...Continue Reading

Summary: Hazardous area classification (HAC) identifies locations where flammable gas, vapour, mist, or combustible dust can form an explosive atmosphere. It classifies areas as Zone 0, Zone 1, Zone 2, or dust Zones 20, 21, and 22 based on release likelihood, duration, ventilation and material properties. A defensible HAC study supports Ex equipment selection, ignition...Continue Reading

SynergenOG is pleased to announce that Aqualis has successfully completed the acquisition of 100 percent of the shares in SynergenOG, a Southeast Asia-based process safety and technical risk management consultancy. SynergenOG will now be integrated with Aqualis’ design and engineering arm, Longitude. SynergenOG expands Longitude’s technical offering in process safety and technical risk management, while...Continue Reading

Summary: Imagine finalizing your facility design, only to discover late in the project that your layout cannot withstand a credible explosion scenario. This is exactly the kind of costly oversight a FERA study is meant to prevent, but only if it’s conducted at the right time. This is what this article explains: What is a...Continue Reading

Summary: What are the typical flaws in a HAZOP process? Why does a HAZOP study/workshop fail to fulfill its targeted aim? This article serves as a guide for engineering and safety professionals to restore the technical integrity of their process safety reviews by crossectioning the root causes of HAZOP failures. Hazard and Operability Study (HAZOP)...Continue Reading

When a plant is approaching startup, the project can look finished long before it is truly safe to operate. Equipment may be installed. Procedures may be circulating. Commissioning may be underway. But once highly hazardous chemicals enter the system, small gaps can quickly escalate into startup delays, loss events, or serious process safety incidents. That...Continue Reading

13 May 2026: Global consultancy group ABL Group has signed an agreement to acquire 100% of the shares in Southeast Asia‑based consultancy SynergenOG, adding specialist capability in process safety and technical risk management and enhancing the group’s end‑to‑end technical offering to the energy industries. Upon completion of the acquisition, SynergenOG will be integrated with the...Continue Reading

What is gas dispersion modelling in risk assessment? Dispersion analysis is the simulation of how a hazardous gas release moves, dilutes, and settles after a leak. It is a core part of quantitative risk assessment (QRA) because it helps safety teams predict toxic and flammable hazard zones, improve gas detector mapping, and support compliance and...Continue Reading
