Offshore hoisting operation risk evaluation method based on analog simulation system

Abstract

The invention discloses an offshore hoisting operation risk evaluation method based on an analog simulation system, and the method comprises the steps: introducing the analog simulation system based on an expert system and statistical data, accurately simulating and truly reflecting the operation characteristics of offshore hoisting operation, carrying out the fault simulation based on the analogsimulation system, and obtaining the risk result information; on the basis of an expert evaluation method, an expert evaluation language is converted into a specific numerical value in combination with a fuzzy mathematical method, risk factors are quantitatively analyzed, the advantages of statistical data, an expert system and an analog simulation system are fully utilized, and the problems of subjectivity and understanding limitation of the expert evaluation method are avoided; compared with an expert evaluation method, the offshore hoisting operation risk evaluation method is higher in objectivity and scientificity, AND the evaluation result is closer to reality; the offshore hoisting operation risk evaluation method based on the analog simulation system has great advantages in risk factor identification and risk consequence evaluation in the complex operation process; AND the method can be widely applied to offshore hoisting operation risk evaluation.

Description

technical field [0001] The invention relates to a risk assessment method for offshore hoisting operations based on a simulation system, and relates to the field of marine engineering operation safety assessment. Background technique [0002] There are currently two operating methods for the offshore installation of offshore oil platforms. One is to use large-scale offshore engineering floating cranes for block hoisting operations, and the other is to use large-scale special-purpose buoyant barges for overall float-over installation operations. The latter is mainly suitable for super-large oceans Installation work on oil platforms. In recent years, with the development of large-scale and complex marine engineering, the lifting capacity of floating cranes has been continuously improved, and the scope of operation has also continued to enter the deep sea, and the requirements for high efficiency in the hoisting process have continued to increase. The "Blue Whale" crane ship wi...

Problems solved by technology

Each hoisting operation is the first operation in a new environment. Under different sea conditions and weather conditions, the same combination of risk factors appears at the same time sequence, which may lead to different consequences

[0006] The subjectivity and cognition limitations of expert systems, data incompleteness, logical uncertainty, timing of risk factors, and fineness requirements of risk analysis are new major challenges for risk analysis of offshore hoisting operations.
