Designing equipment for arctic environments requires special considerations from the design engineer. Low temperatures and harsh environments place special demands on equipment and components. Many materials in common use will experience drastic changes in physical properties, resulting in catastrophic failure of the systems in which they are incorporated. Components may no longer meet original specifications, and instrumentation may not work properly. This design guide should familiarize the design engineer with the factors that must be considered when designing for the Arctic environment. A list of environmental factors and how they may affect a design is first presented. Then, a general design procedure is presented and a detailed analysis of problems and solutions for materials, components and systems follows.
