Pipeline Failure

The combination method of fault tree analysis and nonlinear fuzzy comprehensive assessment method was proposed to make research of oil & gas pipeline failure .The common factors influencing oil & gas pipeline failure could be determined with fault tree analysis .However , the practical operated oil & gas pipeline often have some individual factors and fuzzy ones .Nonlinear fuzzy comprehensive assessment method could evaluate objectively based on evaluated factors sets and weight sets provided by fault tree analysis .The new model steps were listed by taking the example of oil & gas pipeline failure .The result indicates that the method is more reasonable and easier for engineering application , and the evaluation result is more with the objective reality.

Financial Losses

Pipeline transportation is the most important transport mode for crude oil. When oil pipeline operates at low throughput or shutdown, congelation accident always happen as the temperature of oil in pipeline drops, which causes malignant accidents and significant financial losses. Study of the various factors affecting congelation failure is necessary. According to the statistics and analysis of congelation accident, direct and indirect reasons of affecting pipeline congelation failure were determined. Combining with fuzzy comprehensive assessment method, the related importance of factors on congelation accident was studied, and the grade of factors affecting failure congelation of pipeline was also identified. Aiming at the factors, some improvement measures were put forward. These can provide evidences for accident treatment, planned maintenance, security operation and scientific management.

Fuzzy Assessment

Tower crane belongs to high risk equipment in the construction site. Evaluating safety statement of tower crane is a subject of the technical field. The paper setups a new way to evaluate the safety statement of tower crane by means of fuzzy assessment theory. Membership functions have been established for describing the influencing factors of tower crane safety. Fuzzy comprehensive assessment model for evaluating tower crane safety statement has been established. Finally an example for illustrating the method of using the fuzzy comprehensive assessment to analyzing the tower crane safety statement.
