Flooding Risk Assessment of Motor Bancas Operating in the Philippines

This paper focuses on describing the process of assessing the flooding risk, as well as identifying and implementing cost-effective solutions, for designing new or for retrofitting existing motor bancas, representative of some 10,000 of these boats, serving most of the domestic trade in the Philippines. To this end, the selected design has been subjected to a systematic process of damage stability and flooding risk analysis in order to identify design vulnerabilities, leading to risk estimation in the form of PLL. A number of risk control options have then been identified, enabling a thorough risk assessment and identification of costeffective RCOs, as well as impact assessment, using IMO risk acceptance criteria as the basis and the metric of Potential Loss of Life, facilitating estimation. The process of risk analysis and risk assessment is then detailed, the latter providing a cost-benefit assessment to aid decision-making in the RCOs selection, practical implementation, and impact.
