We have all heard about tragic accidents and the sad stories of lost lives at sea when vessels capsize or sink, due to a collision or grounding. It does not occur that often, but when it does, the consequences can be devastating and catastrophic.


hus the question seems valid: are ships built under the present regulations really safe enough? And


how do we support the crew during emergency situations, enabling them to make life saving decisions?


Beyond IMO regulations In a joint European Research project under Horizon 2020, named FLooding Accident REsponse (FLARE), 19 partners are working together with the aim of delivering a risk-based methodology (framework) for ‘live’ flooding risk assessment and control, which can potentially be applied to newbuildings and existing ships. The EURO 9.4 million project

focuses on the safety of cruise ships and Ropax vessels.


MARIN is making a significant contribution of EURO 1.25 million to the project and is responsible for Work Package 4 concerning “Numerical Simulations and Verification”. In this Work Package, model tests are conducted and numerical simulations of flooding are benchmarked. At the heart of the framework for damage stability risk evaluation is the use of dynamic flooding simulations that predict how the water progresses through the ship over time, taking into account the effect of ship hydrostatics, hydrodynamics and waves.


The outcome of the simulations enhances the designers’ and operators’ insight into the flooding risk quantification beyond the current IMO regulations.


MARIN has been developing dynamic flooding simulations within the FREDYN project for many years. Although the flooding equations are “just” the classical Bernoulli equations, the complexity of the ship compartmentation, with many compartments and flooding openings, and possible air entrapment in combination with large ship motions, makes dynamic flooding simulations a very challenging topic.
