What are the consequences if the risk does occur ? Class & Risk Management _ Shipping and the Law, Naples, 3 October 2013 3 Implementation of risk management methods ► FSA: Formal Safety Assessment ► Applied in many sectors regarded as risk- prone ► Offshore industry : the Safety Case Origin : Piper Alpha accident (1988) Norway and the UK both shifted from prescriptive to goal‐setting regulation Requires a Safety Case to make the case to the regulator that the proposed installation and its operation are safe Class & Risk Management _ Shipping and the Law, Naples, 3 October 2013 4 New approaches in the maritime safety regulatory regime: Formal Safety Assessment (FSA) ► Introduced in 1993 by UK at IMO ► Defined as “a rational and systematic process for accessing the risk related to maritime safety and the protection of the marine environment and for evaluating the costs and benefits of IMO’s options for reducing these risks” ► FSA Guidelines defined by IMO ► Applied to high-speed craft, oil tankers (propulsion and emergency steering devices), bulk carriers (Double Side Skin) ► Series of problems raised by FSA ► Possible links between FSA and GBS Class & Risk Management _ Shipping and the Law, Naples, 3 October 2013 5 FSA: A five step risk based approach Preparatory Step Definition of Goals, Systems, Operations Hazard Identification Step 1 Hazard Identification Scenario definition Cause and Frequency Analysis Consequence Analysis Step 2 Risk Assessment Risk Summation Options to decrease Frequencies No No Risk Controlled? Options to mitigate Consequences Step 3 Risk Control Options Yes Cost Benefit Assessment Reporting Step 4 - Cost Benefit Assessment Step 5 - Recommendations for Decision Making Class & Risk Management _ Shipping and the Law, Naples, 3 October 2013 6 Classification and risk management approach ► Genesis of classification rules State of the art of the naval architecture Return of experience ► 3 factors have impacted new rules Development of GBS New technical challenges Recognition of alternative design Class & Risk Management _ Shipping and the Law, Naples, 3 October 2013 7 Goal Based Standards (GBS) and Common Structural Rules (CSR) TIER I Goals TIER II Functional requirements TIER III Verification criteria TIER IV Prescriptive Regulations & Class Rules TIER V Applicable industry and Code of Practice Class & Risk Management _ Shipping and the Law, Naples, 3 October 2013 8 Classification rules for very large vessel ► Mega containerships New hydro structural issues in design and verification processes Springing and whipping phenomena Slamming effect ► Very Large Ore Carriers Procedure for directly calculating fatigue assessment Advanced calculations ensure that all critical structures are adequately designed to meet specified fatigue and strength requirements ► Ultra Large Crude Carriers Class & Risk Management _ Shipping and the Law, Naples, 3 October 2013 9 Classification of ships/units in Arctic conditions The Northern Sea Route (NSR) NSR cargo transit is growing 2012 : 46 transits (1.3 M tons) 2021 : 40 M tons (est.) NSR 6,920 nm (*) Bureau Veritas Artic initiatives Ice Class Rules and Notations IceSTAR Software Tool Direct Calculation of ice loads for a Panamax bulk carrier Design considerations/studies of a LNG carrier/FPU for operation in the Arctic SCR 11,430 nm (*) (*) = Hamburg - Shanghai Class & Risk Management _ Shipping and the Law, Naples, 3 October 2013 10 Risk base substantiation alternative designs ► Risk analysis: a recognized means to support design well established in the offshore industry when designs have to met specified safety criteria set by an operator or a regulation authority ► Ship design to be risk-based ? SOLAS reg. II-2 /17 allows alternative designs to be substantiated by a risk analysis for passenger ships ► It provides flexibility in order to adapt safety measures to novel designs in a reasonable manner, as long as the proposed alternative is demonstrated to be as safe as the prescriptive solution. Class & Risk Management _ Shipping and the Law, Naples, 3 October 2013 11 Conclusion: consequences for the shipping community ► New duties for class societies Integrates risk-based methods in formulating new rules Rules Implementation : risk-based inspection Class provider of risk services ► Shipowner to assume a greater responsibility Ships at a minimum level of safety TMSA programme for tankers ► IMO : the future of maritime safety Class & Risk Management _ Shipping and the Law, Naples, 3 October 2013 12
