TMC Services can identify and integrate functional, engineering, safety, regulatory, design, construction, environmental and operating requirements into comprehensive safety analysis reports (SARs) that remain effective over the entire life cycle of a facility. TMC Services develops technical specification requirements and safety analysis requirements and identifies design, construction, and operating requirements. TMC Services manages deterministic and probabilistic safety analyses, pioneering the development of some of these tools. TMC Services develops detailed system risk models, accident progression event trees, and other engineering analyses to support probabilistic risk assessment models and decision analysis. TMC Services' extensive experience in threat and vulnerability assessments includes on-site engineering surveys, system deployment logistics and development of highly complex interdiction plans based on operations research.
