Comfort on board

Paper

The aspects related to the vibrational behaviour of the ship are significant for issues relating to possible fatigue stress on structure, heathy and onboard operators’ comfort reasons. Nowadays, this is even more significant due to the need of keeping the hull weight that leads to plan increasingly lightweight and less rigid structures and therefore more likely to experience vibrational and...

Stability, Seakeeping, Maneuverability

Paper

The International Maritime Organization has formally approved, as recommended guidelines, the methods and procedures of the Second Generation Intact Stability Criteria (SGISC). These criteria introduce the concept of dynamic stability in the intact stability assessment of ships and define the failure modes that might occur to a ship that navigates in harsh sea conditions. This paper focuses on...

Stability, Seakeeping, Maneuverability

Paper

One year later the finalization of Second Generation Intact Stability criteria (SGISc), there is still the need to validate the robustness and consistency of these criteria as indicated by IMO. The stability failures addressed by SGISc take into account the dynamical aspects in relation with the actual seaway conditions which may affect the ship stability performances, i.e. they focus on the...
