RISK ASSESSMENT MATRIX FOR PORT INFRASTRUCTURE

1. RISK ASSESSMENT MATRIX FOR PORT INFRASTRUCTURE CHRIS EDWARDS AECOM Inc

2. Ports have a variety of infrastructure subject to deterioration. The most severe deterioration occurs on the main working assets such as wharves and jetties, principally from chloride attack on steel. Assets must be kept in good working condition within tight budgets Asset managers need to prioritise their maintenance programs to be able to plan for future budgets. Often this is done on the basis of condition alone and ignoring the consequences of loss of service or failure

3. The AECOM Risk Assessment Deterioration Model (RAM) is a tool that allows assets to be ranked according to their requirement for maintenance based on condition and consequence of loss of service or failure

4. Time Dependent Deterioration Time Dependent Chloride Ingress & Corrosion

5. Repairs should be timely The ranking of assets allows: • Remediation to be prioritised and scheduled • Multi-year maintenance budgets to be estimated with confidence

6. The AECOM RAM is a multi-step process based on Likelihood and Consequences 1. Select the Likelihood Rating based on the data points 4. Select the Consequence Ranking 2. Select the weighting for each data point 5. Select the Consequence Weighting 6. Calculate the Consequence Multi Criteria Assessment 3. Calculate the Likelihood Multi Criteria Assessment Calculate the Severity of Risk
