Abstract In setting a safe route for a ship, one of the problems to face is represented by excessive roll motions deriving from resonance phenomena in adverse weather conditions. An effective prediction of the roll motion amplification is related to a proper mathematical modelling of the ship motions. Linear models may result to be inadequate in case of large roll motions, where non-linear effects dominate. This paper investigates the roll response resonance in irregular waves. The developed met...

Ship accidents that entail flooding may lead to disastrous consequences which could be avoided or mitigated based on the knowledge of damaged ship dynamics. The dynamic behaviour of a damaged hull is a complex phenomenon involving the interaction of the flooded water and the ship motions. The presence of a damage opening allows water flow into and out from the compartment, which further complicates the mathematical description of the problem. A fast simulation method, based on the lumped mass ap...

Abstract A proper estimation of the ship accelerations, particularly in the transversal direction, is fundamental for predicting the risk of cargo shifts and inherent structural damages in severe irregular seas. A specific situation worth to be considered in this context is the so-called dead ship condition, in which the ship, because of a loss of steering capabilities, is drifting in beam waves at zero speed. Particularly in this situation, a proper modelling of ship dynamics in wave is deemed ...

Abstract The concept of autonomous merchant ships is quite recent. The increasing interest in autonomous vessels is nowadays calling for smart technologies that are supposed to replace the human actions on board. This involves troublesome issues related to ship safety. In the future, decision-making processes that are conventionally performed by human beings on board ship will be moved ashore to the control centre and maybe even completely replaced by computers and smart technologies. This paper...

Abstract The dynamics of a damaged ship in waves is a complex phenomenon regarding fluid and structure interactions. Flooded water motions in the damaged compartment could be influenced by decks, obstructions and obstacles in the compartment. This becomes particularly relevant in case of flooding in the engine room that is usually characterized by the presence of large objects such as engines and machineries. In such cases the possibility to better understand the behavior of a damaged ship, infl...

Abstract Synchronous roll and parametric roll resonance are critical phenomena that lead a ship, under certain conditions, to quickly develop large roll amplitudes. This will result in excessive accelerations that can be dangerous for a ship and her cargo. Ships with large bow and stern flare (i.e. container carriers and RoPax) are especially prone to this type of hazards. Therefore, it is of utmost importance for ship operators to be aware of a set of conditions under which these two unwanted p...

Abstract A large number of containers is lost every year from ships along shipping routes. Even though the economic losses are in most cases covered by insurance, the containers drifting in sea may compromise the safety of navigation. Moreover, there can be serious consequences for the environment, in terms of pollution. All the reported losses were caused by extremely violent motions of containerships, due to adverse weather conditions. This pointed out the need of further researches on safer c...

The verification of ship stability has been historically carried out on the GZ curve and on the dynamic lever curve. They are both evaluated in still water. Recently, new methods have been developed, accounting for dynamic instabilities in waves. The present research study aims to investigate on the dynamic stability of a ship in waves. This is carried out by means of numerical simulations of the transient roll response of the ship, caused by sudden heeling action. The effective influence of lon...
