Dropped Object Impact Analysis Considering Frequency and Consequence for LNG-FPSO Topside Module

Recently, quantitative risk assessment (QRA) has been widely used as a decision-making tool in the offshore industry. This study focused on analyzing dropped objects design of modern platform. A modified QRA procedure was developed for assessing production module protection against accidental external loads. Frequency and consequence analyses were performed using procedure. An exceedance curve plotted, high-risk management item derived through this process. In particular, simulations experiments to verify difference between potential impact energies according drop orientation. When object specific orientation, energy confirmed be up 4.7 times greater than energy. To reflect results structural design, proposed should calculate maximum The provides step-by-step guide assess damage capacity area well frequency consequences.
