Evaluation of safety monitoring scheme for offshore floating platform based on the multiple connection numbers

Abstract

To accurately evaluate the safety monitoring scheme of offshore floating platform, a five-element connection number analysis method for evaluating the safety monitoring scheme of offshore floating platform was developed in this paper. According to the characteristics of safety monitoring of offshore floating platform, an index system was constructed. Considering the complexity and uncertainty in the evaluation of safety monitoring schemes, the Set Pair Analysis based on the five-element connection number was used to establish the similarity, difference and reverse evaluation model of safety monitoring schemes for offshore floating platforms. In addition, entropy weight method was employed to calculate the objective weights. Taking an offshore floating platform project in Guangdong, China as an example, a case study was carried out. The study showed that the evaluation grade of this monitoring program was good and the scientificity of the programming method is the most important influencing factor. The research results provided a theoretical basis for the safety monitoring scheme management of offshore floating platform.
