Our chemical engineering consultants apply principles of chemistry, physics, and engineering to investigate incidents, identify hazards, and optimize processes for clients in a wide range of industries.
We conduct investigations and provide root cause analyses when large, complex chemical or petrochemical incidents occur, such as fires, explosions, chemical releases, and runaway reactions. Leveraging in-house expertise in material science, thermal interactions, and asset integrity, our experts determine how and why an incident occurred and identify the presence of recurrent hazards.
Where safety and efficiency intersect, we specialize in risk and reliability engineering to deliver comprehensive evaluations in accordance with ASTM and industry standards. Our certified experts evaluate risks associated with the production, storage, and transportation of hazardous materials. We employ custom methods including Process Hazard Analysis (PHA), Consequence Modeling (CM), and Safety Systems Inspection, Testing and Maintenance (ITM) to increase production efficiency of unit operations involving mass transfer, heat transfer, and chemical reactions.
Whether consumer protection, workplace safety, or environmental implications, we have the industry knowledge, hands-on experience, and technical expertise required to meet the needs of our clients based on the scope of each project.
