초록
Offshore fields are increasingly important for the development of offshore resources due to the growing energy needs. However,anoffshore field for oil and gas production has difficult development conditions, e.g., high temperature, high pressure, sweet/sour compositions of fluids,etc. Corrosion is one of the biggest issues for offshore pipeline engineering. In this study, a Corrosion Resistant Alloy (CRA) pipe for corrosionprevention was investigated through its global demand and trends, and three types of CRA pipelines were introduced with detailed explanations. The usefulness of CRA was also evaluated in comparison to a carbon steel pipeline in terms of the structural strength, cost, and other factors. Offshore pipeline engineering, including mechanical design and verification of the results through an installation analysis based on numericalsoftware, was performed for the carbon steel type and solid CRA type. The results obtained from this study will be useful datafor CRA pipelinedesigners and researchers
