Unascertained Measure——a New Tool of Safety Assessment for Platform Installation
To deal with the unascertained information and solve the problem of the data shortage in the safety assessment of the offshore platform installation procedure, a mathematical tool,the unascertained measure, was proposed. First, the basic knowledge of the Unascertained Sets and the essential difference between the Unascertained Sets and the Fuzzy Sets were analyzed systematically. Second, the unascertained measure was defined and the credible identification model was set up. Then the method was introduced into the field of safety assessment of jacket installation procedure. Finally, engineering practices show that it can complete the safety assessment systematically and scientifically without any assumption. The work provides a method for safety assessment and it has significance in theory and practice for offshore engineering.
