THE RAPID RELIABILITY AND RISK ASSESSMENT OF DAMAGED SHIP STRUCTURE

摘要

The rapid assessment of residual structural strength of a damaged ship subsequent to major accident such as collision,grounding etc. is essential for fast response to minimise damage because of consequence in loss of strength. Evaluationof strength of complex structures such as that of a ship is a hard and time consuming task. Presently used computer aidedstructural analysis tools such as Finite Element Analysis and related technologies are neither developed for EmergencyResponse Services nor suitable for such application needing quick assessment of structural strength. A computer aidedstructural analysis tool based on artificial neural network and structural response parameters can provide rapid strengthassessment and shall be of immense help for Emergency Response Services to make reliability and risk assessment ofresidual structural strength and to formulate informed and reliable emergency response actions. This paper is aimed topresents such techniques for reliability and risk assessment of damaged ship structures.
