Parametric Roll Instability of Ships [PDF]
Parametric roll may be defined as the spontaneous rolling motion of the ship moving in head or following seas that comes about as a result of the dynamic instability of motion. The development of the parametric roll occurs under the conditions that the encounter angular frequency is approximately twice the roll angular frequency, the wavelength is equal

Nonlinear Observers for Parametric Roll [PDF]
Parametric roll resonance is a dangerous resonance phenomenon affecting several kinds of ships, such as cruise ships, fishing vessels and container ships. In a worst case scenario parametric roll resonance may lead to roll angles of up to 50 degrees, capsizing of the vessel, or damage of goods and ship for tens of millions of dollars, citep ...

Modeling and Control of Parametric Roll Resonance [PDF]
Parametric roll resonance is a dangerous resonance phenomenon affecting several types of ships, such as destroyers, RO-RO paxes, cruise ships, fishing vessels and especially container ships. Worst case, parametric roll is capable of causing roll angles of at least 50 degrees, and damage in the tens of millions of US dollars.

Stability Analysis of Randomly Excited Ship Parametric Roll Resonance
In this paper, ship stability of randomly excited parametric roll resonance is studied. Parametric roll resonance will lead to severe roll motion and even capsize. Studies on parametric roll resonance have many challenges for the randomness and nonlinear.

The Smart Detection of Ship Severe Roll Motions and Decision-Making for Evasive Actions
This paper presents a numerical model for the smart detection of synchronous and parametric roll resonance of a ship. The model implements manoeuvring equations superimposed onto ship dynamics in waves.

Flow phenomena in fixed-gap and gravure roll coating systems [PDF]
This thesis describes investigations into a number of coating processes using experimental, analytical and computational techniques. The first problem, considered experimentally, is that of reverse roll coating with a liquid reservoir positioned ...

A Numerical Application of Ship Parametric Roll under Second Generation Stability Criteria [PDF]
In this study, the parametric roll motion for the benchmark container ship form C11 is investigated by using the second generation stability criteria, which were intensively studied by IMO (International Maritime Organization).

Parametric roll oscillations of a hydrodynamic Chaplygin sleigh
Biomimetic underwater robots use lateral periodic oscillatory motion to propel forward, which is seen in most fishes known as body caudal fin (BCF) propulsion. The lateral oscillatory motion makes slender-bodied fish-like robots roll unstable. Unlike the case of human-engineered aquatic robots, many species of fish can stabilize their roll motion to ...
