Evolution of ship damage stability assessment—Transitioning designers to direct numerical simulations

Mauro, F. (author), Vassalos, Dracos (author), Paterson, Donald (author), Boulougouris, Evangelos (author)

Theory and application of damage stability followed over the years two dissociated paths: static assessments and dynamic simulations. The first approach, being easy to apply and understand, has been preferred by ship designers and regulators; the second, more advanced and first-principle oriented, has been mainly reserved for research or high...

Damage surrogate models for real-time flooding risk assessment of passenger ships

Mauro, F. (author), Conti, Fabien (author), Vassalos, Dracos (author)

Real-time assessment of flooding risk associated with the collision between two ships, requires a fast estimation of damage dimensions and associated survivability. The state-of-the-art frameworks for risk assessment on passenger ships do not consider a direct evaluation of damages through crash simulations but refer to probabilistic...

The effect of the operational environment on the survivability of passenger ships

Mauro, F. (author), Vassalos, Dracos (author)

The in-force probabilistic framework for passenger ship survivability assessment covers collision hazards. The framework primarily pertains to a static approach. Nonetheless, more complex dynamic analyses usually employ the same damage definitions, adding besides the breach characteristics, the environmental condition selection or, more...

Real-time flooding risk evaluation for ship-to-ship collisions based on first principles

Vassalos, D. (author), Paterson, D. (author), Mauro, F. (author)

Flooding risk identification is a task always treated within a very narrow scope between the life-cycle of a passenger ship. Therefore, different approaches and methods are available for design, operational or onboard applications. Furthermore, the models employed and proposed solutions use simplified methods based on empirical or...

Exploring smart methodologies for critical flooding scenarios detection in the damage stability assessment of passenger ships

Mauro, F. (author), Vassalos, Dracos (author), Paterson, Donald (author), Boulougouris, Evangelos (author)

A more contemporary damaged stability assessment of a passenger ship can be addressed with a non-zonal approach, assessing multiple damage types and environmental conditions and employing dynamic analysis for ship survivability. This direct method necessitates the generation and simulation of many damage scenarios. However, the probabilistic...

Critical damages identification in a multi-level damage stability assessment framework for passenger ships

Mauro, F. (author), Vassalos, Dracos (author), Paterson, Donald (author)

The damaged stability assessment for a passenger ship is a process requiring the simulation of multiple damage scenarios. Nevertheless, the stochastic nature of the damage stability framework requires the analysis of a statistically significant number of cases. On the other hand, the probability density functions used to estimate the possible...

Process, methods and tools for ship damage stability and flooding risk assessment

Vassalos, Dracos (author), Paterson, Donald (author), Mauro, F. (author), Mujeeb-Ahmed, M. P. (author), Boulougouris, Evangelos (author)

Development of damage stability as a scientific subject, specifically in damage ship hydrodynamics and, generally, flooding risk assessment, has evolved primarily by inquisitive academics with support by people with vision and passion towards maritime safety enhancement from industry and Government, the latter in the wake of serious accidents...
