Iceberg Stability Investigations Using Machine Learning for Alaska and Greenland
Iceberg-capsize tsunamigenesis is a coastal hazard not often discussed or observed due to the lack of frequency of which this process occurs. Greenlandic communities are proximal to coasts and are at risk of tsunamis caused by unprompted iceberg-capsize. We use time-lapse imagery from our own sites …

Application of Lyapunov Exponents to Strange Attractors and Intact & Damaged Ship Stability
The threat of capsize in unpredictable seas has been a risk to vessels, sailors, and cargo since the beginning of a seafaring culture. The event is a nonlinear, chaotic phenomenon that is highly sensitive to initial conditions and difficult to repeatedly predict. In extreme sea states most ships …

Analytical and Numerical Methods Applied to Nonlinear Vessel Dynamics and Code Verification for Chaotic Systems
… etc. Two classical chaotic models and two ship capsize models are examined. The current approach overlaps entrainment in chaotic control theory. Here entrainment means two dynamical systems have the same period, phase and amplitude. The convergent region from control theory is used to give a …

Ship Rolling Motion Subjected to Colored Noise Excitation
… The ship will finally leave the safe domain and capsize in the probability?s view. It is also shown the similarity of probability density contours between the case of white noise wave excitation and the case of colored noise wave excitation.

Capsizing of ships : static and dynamic analysis of wind effect and cost implications
… case and the wind speeds that caused the ship to capsize are calculated.

A New Method to Predict Vessel Capsizing in a Realistic Seaway
… shortterm irregularity of the design seaway. The capsize risk associated with operation in a given sea state can be evaluated during the design stage or when an operating area change is being considered. Moreover, this technique can also be used to guide physical model tests or computer simulation …

"Performance-based damage survivability of passenger ships and design implications"
… can be accurately predicted and how time to capsize can actually be related to survivability in waves. In order to achieve this, established concepts like the critical significant wave height have been revised. Moreover, the proposed modifications of the s-factor can link it directly to …

Dynamic stability assessment of damaged passenger ships using a time simulation approach
… the basis of maximising the danger of potential capsize (or sinkage) while taking into account actual accident records. The practical applicability of the proposed procedure is demonstrated by means of a parametric investigation aimed at identifying the effect of a number of key parameters on the …

A framework for ship stability in a seastate using the state-space Fokker-Planck method
… to potentially the most catastrophic events capsize, and loss of cargo and life. This compels the need to reliably predict vessel responses to wave interactions in order to aid the decision-making process for operating the ship safely. Despite the advances in computational methods and …

Analysis and Modeling of Hydrodynamic Components for Ship Roll Motion in Heavy Weather
… of crew injury, cargo damage, or even capsize, it is important to understand the behavior of the roll added inertia and damping for these conditions. Dead ship conditions, where ships may experience excitation from beam, or near beam, seas present a worst case scenario in heavy weather. …

Quantifying human performance during passenger ship evacuation
… accidents still occur that result in sinking or capsize. When this happens to passenger ships, the results are often shocking and devastating with loss of life, sometimes numbering in the thousands. For this reason, the International Maritime Organization (IMO), which regulates the maritime …

Analytical and computational methods for non-Gaussian reliability analysis of nonlinear systems operating in stochastic environments
… both to avoid catastrophic failures like capsize or hull breach, but also to make long term plans such as maintenance schedules, fatigue calculations, and route selections. These statistics are especially important during the design phase, when the statistical performance of different hull …
