摘要
海洋平台现已广泛应用于海洋资源开发,对其进行安全评价是一项具有全局性的重要任务。现今的评价多集中于其使用与维护,且评价方法的可信度与可解释性较差。文章较为系统地介绍了未确知集的基本知识及与模糊集的区别,并引入海洋平台安全评价中,对平台组块装船过程进行了安全评价,结果表明,评价结果的置信度与可解释性增强,该方法对海洋工程具有重要的理论与现实意义。
Platforms have been widely used in offshore oil exploring. Safety assessments of them are urgent tasks. The safety assessments now are focusing on the application and maintenance of the platform and the methods employed have many shortcomings, they cannot make the reliability well explicable. The basic knowledge of the Unascertained Sets and the essential difference between the Unascertained Sets and the Fuzzy Sets were analyzed systematically. The unascertained measure was proposed and the credible identification was set up. Then the method was introduced to the fields of safety assessment of jacket and modular loadout. Finally, engineering practice showed that it could complete the safety assessment systematically and scientifically without any assumption. The work has significance in theory and practice for offshore engineering.
