An overview of the prediction methods for roll damping of ships

Abstract: Of all the six degrees of freedom, the roll motion of a ship is the most poorly understood and displays complicated phenomena. Due to the low potential wave damping at the natural frequency, the effective analysis of ship roll dynamics comes down to the accurate estimation of the viscous roll damping. This paper provides overview of the importance of roll damping and an extensive literature review of the various viscous roll damping prediction methods applied by researchers over the years. The paper also discu… Show more

“…Himeno (1981) reviewed various methods used by practitioners, many of which remain common practice in the industry today. More recent reviews of the prediction methods have been provided by Ikeda (2004), Falzarano et al (2015) and Piehl (2016), for instance. The most frequently employed approach, which is referred to as Ikeda's method (see also Kawahara 2012…”

“…), and can be obtained by analyzing the results of free decay tests. Bilge keel damping may also be calculated empirically by using various empirical formula based on experiments (Himeno, 1981;Kawahara et al, 2008Kawahara et al, , 2012Falzarano et al, 2015). Damping caused by mooring and risers can also be calculated using lump-mass type dynamic line model with Morison drag and added mass defined on each element.…”

“…Roll motion of a ship has always been a prime concern for many researchers in the marine field due to its importance and its possible consequence on the ship stability, operability, cargo handling activities, or comfort on board and sometimes even on the survivability of the ship. It is also considered as one of the least understood ship motion among all the six degrees of freedom of a ship as it was argued by Falzarano et al [1], who correlated this lack of understanding to the shortage in predicting the viscous roll damping. The damping effect is one of the most important aspects that should be taken into consideration when talking about roll motion prediction, especially if the ship is designed to sail in moderate or rough sea conditions, where the parametric rolling and possibly loss of stability are subjected to occur.…”
