“…To validate the method special attention has been attributed to breach validation by comparisons against LS-DYNA. A benchmark study accounting for different scenarios of collision between the NAPA D-RoPax passenger ship and Floodstand Ship B cruise ship demonstrated good agreement between different methods developed by different project partners irrespective to modelling simplifications [4]. For both collision and grounding cases comparisons showed good correlation.…”

Mitigating flooding risk through passive and active measures is a key step in further increasing the safety of shipping, reducing loss of life and damage to the environment. This paper presents key findings from the EU Horizons 2020 project FLARE (FLooding Accident REsponse) that introduces a novel risk-based methodology beyond the state-of-the-art for “live” flooding risk assessment and control, with potential application to new and existing ships. The project develops a flooding accident model – based on statistics and first-principles tools – that aims to assess the frequencies of flooding events whilst accounting for pertinent environmental conditions and design parameters including ship crashworthiness. Cost-effective risk control options are under evaluation and possible recommendations and/or amendments to the regulatory framework will be submitted to the IMO.

“…These two principal features are considered in the software SHARP, which allows for performing fast collision simulations. The accuracy of this method was recently reconfirmed during Project FLARE, by benchmarking against Finite Element codes ( Kim et al, 2022). Furthermore, the methodology allows for building damage databases suitable not only for the generation of damages in the design stage (Conti et al, 2022) but also for the estimation of risk in real-time applications (Mauro et al, 2023b).…”

The design of a passenger ship is a complex process covering multiple aspects of naval architecture and marine engineering to address performance, functionality safety, and cost as primary objectives. Between them, safety is a key element focusing on the people on board. In this sense, ship safety in the case of flooding events needs proper estimation from the first stages of the design process employing an appropriate metric. To this end, safety can be evaluated as a risk by calculating the Potential Loss of Life. Thanks to a multi-level framework developed during project FLARE, it is possible to calculate the risk associated with an accident, increasing the level of reliability as the design process advances. The framework aims at employing first-principles tools from the early stages of the design process, abandoning static calculations and empirical formulae as soon as data is available to set up advanced calculation techniques. Then, the framework adopts rigid-body time-domain calculations for the flooding simulations, advanced evacuation analysis tools, and direct crash simulation to evaluate collision damages. The process allows for testing alternative design solutions for the ship to enhance safety. Investigating risk control options is also possible, considering active or passive systems such as fixed foam installations, deployable barriers, or crashworthiness. Such an approach allows for evaluating safer solutions, respecting other design constraints and cost-related aspects. The present work describes the risk assessment framework for the case of flooding events, together with the different levels of accuracy that can be achieved, showing the improvements that could be reached by employing alternative risk control options.
