LIFEBOAT LAUNCH SIMULATION AND ITS APPLICATION TO SAFETY ASSESSMENT

The paper deals with the motion simulation of lifeboats launched from fixed or floating platforms and its application to collision risk assessment. The mathematical model of the Davit launch system is presented. By solving the motion differential equations, the three dimensional motions responses of the lifeboat and the platform are simulated in the time domain and the clearance between the lifeboat and platform structural members are monitored. Numerical examples are given and key parametric effects are investigated through deterministic and probabilistic analyses. It is demonstrated that the motion simulation combined with probabilistic analysis techniques can provide an effective tool for quantitative risk assessment of offshore emergency evacuations using lifeboats.
