Risk Control and Cost Benefit Analysis of Docking Operation

Abstract

In this paper, a failure/accident analysis model is proposed to develop the cost-effective safety measures for preventing accidents in dry docking and undocking operations.The model comprises two parts. In the first part is a quantitative failure analysis model built by Bayesian Network (BN) which can be utilised to present the corresponding prevention measures.In the second part, the proposed prevention measures are ranked in a cost-effective manner through a Bayesian Network (BN) approach.A case study is analysed as an illustration. The case study shows that the proposed model can be used to seek out failure/accident causes and rank the derived safety measures from a cost-effectiveness perspective.The proposed model can provide accident investigators with a tool to generate cost-efficient safety intervention strategies.
