Reliability evaluation of conceptual design for the dehydration package
- 17 Downloads
In this study, reliability evaluation in conceptual design stage is performed to develop the dehydration package of offshore plant equipment. Dehydration package is commonly used in the gas treatment system but has still being developed. Since the technology for the dehydration package relies on almost 100 % in overseas companies, it is necessary to acquire the design/engineering technology for dehydration package. The design must also consider reliability and safety with the special characteristic of ocean environment and the danger of gas process. Therefore, the concept of adsorption dehydration package and design philosophy for development of dehydration package is derived through reliability evaluation in conceptual design stage in this study. After defining the equipment for dehydration package by IDEF0, reliability evaluation of conceptual design for the dehydration package is performed using fault tree analysis (FTA), based on the result of hazard identification (HAZID) analysis. In the future, this result will be applied in detail design.
