What Unwin does

Unwin Company is a private process safety and risk management consultancy founded in 1996 and headquartered in Columbus, Ohio. The firm specializes in process hazard analysis (PHA), quantitative risk assessment (QRA), and regulatory compliance for OSHA Process Safety Management (PSM) and EPA Risk Management Program (RMP) requirements. Its client base spans commodity and specialty chemicals, petroleum refining, petrochemicals, pharmaceuticals, semiconductor manufacturing, ammonia production, water treatment, fossil and nuclear power generation, nuclear fuels processing, and waste management. The company also operates a Government Services Division established in 2007 to provide technical support to the U.S. Department of Energy's Office of Enterprise Assessments for independent oversight of safety and security at DOE facilities.

Unwin's offerings combine professional consulting services with proprietary Excel-based software tools — ePHA for electronic process hazard analysis documentation supporting HAZOP, What-If, FMEA, and LOPA methods; eFTA for fault tree analysis and Safety Instrumented System logic modeling; and eVA-H2O for water system vulnerability assessments using Sandia National Laboratories' RAM-W methodology under EPA contract. The firm's principals, including President Robert W. Johnson (former AIChE Fellow with 40+ years in risk analysis, prior senior roles at Hercules, Du Pont, and Battelle) and Principal Steven W. Rudy (35 years' experience), are lead contract authors of five AIChE Center for Chemical Process Safety (CCPS) guidelines books spanning 1995 to 2017.

Revenue is generated through direct consulting engagements with multi-year contract structures and ancillary software licensing, delivered via sales-led direct engagement with enterprise industrial and government clients. The firm maintains a corporate membership in the AIChE Center for Chemical Process Safety and a Partner in Safety relationship with Safteng.net, and has been providing process safety and risk management consulting for over 30 years.
