Services System Safety and Technology Evaluation

Because of safety and liability concerns, both the public and private sectors have been increasingly interested in studying the causes, probabilities, and consequences of accidents associated with the production, storage, transport, and use of hazardous and toxic materials. Aspen provides the thorough knowledge of processes, equipment, and procedures required for safety and hazard assessments and mitigation, as well as knowledge of methods of release, dispersion, and consequence analysis.

Services and Capabilities
  • Analysis of system safety implications and risk of upset for pipelines and industrial and waste management facilities, including hazard footprint analysis and development of mitigation measures
  • Oilspill analysis, including identification of probability of occurrence, maximum spill volumes, and dispersion and fate of oil in both the marine and terrestrial environments
  • Calculation and evaluation of risk and accident statistics and development of mitigation measures for transportation projects
  • Preparation and review of emergency response and oil spill contingencyplans
  • Development of risk management and prevention programs
  • Evaluation of treatment options and waste minimization and pollution prevention opportunities
Selected Project Experience
  • Evaluation of Pipeline Risk

    Aspen staff and specialty subcontractors have evaluated risks associated with several crude oil, gasoline, and petroleum products pipelines, including identification of rupture or spill probabilities, spill volumes, fate and consequence analysis, and comparative analysis of pipeline alternatives. Key project examples include the Yellowstone Pipeline (petroleum products) in western Montana and northern Idaho; the Pacific Pipeline (crude oil) in southern California; the Kinder-Morgan Carson to Norwalk Pipeline (petroleum products), also in southern California; and a risk evaluation for a proposed petroleum products pipeline in New Mexico for a confidential client.

  • Marine Oil Spill Analysis

    For the Gaviota Marine Terminal Project (crude oil), Aspen managed a comprehensive analysis of marine oil spills offshore California, including the Santa Barbara Channel, the Los Angeles Harbor area, and the San Francisco Bay area. This project involved utilization of several state-of-the-art models of oil spill transport and fate in the marine environment. Aspen analyzed the capabilities and efficiencies of existing emergency response resources in containment, removal, and clean up operations.

  • Hazard Footprint Analysis

    Aspen staff prepared and analyzed hazard footprints for tanker accidents, oil terminals, drill sites, refineries, and fuel pipelines for private clients, public agencies, and for several U.S. Navy facilities. These studies included computer modeling of accidental releases of such gases as hydrogen and ammonia, and accidental rupture of truck and railroad car tanks.

  • Accident Analysis

    Aspen has evaluated the safety and accident potential for alternative modes of transporting hazardous materials (including tankers, pipelines, unit trains, and trucks) for a crude oil pipeline and for a hazardous waste storage and treatment facility. Aspen also evaluated upset conditions for the hazardous waste facility and the potential consequences upon surrounding land uses. Analysis included comprehensive release simulation, fire analysis, dispersion, and consequence analysis.

  • Evaluation of Treatment Technologies

    Aspen prepared a feasibility report for a potato processing plant in Oregon. The report evaluated the applicability of electrostatic precipitation and biofiltration in abating odors from hot oil fryers. Aspen principals prepared several reports for the EPA's Office of Solid Waste to evaluate treatment technologies for various pollutants and hazardous wastes. Aspen principals also participated in several studies for the California EPA Department of Toxic Substances Control to evaluate technologies and procedures to reduce the amounts of wastes generated by several industries.
