Proc. ASME. OMAE2021, Volume 2: Structures, Safety, and Reliability, V002T02A036, June 21–30, 2021
Paper No: OMAE2021-61424
...Abstract Abstract Large modern container ships feature an open cross section which results in a low stiffness of the vessel to global hull excitation. The contribution of whipping is a significant portion of the overall acceleration and stress response of such a vessel. Whipping results...

Proc. ASME. OMAE2013, Volume 5: Ocean Engineering, V005T06A056, June 9–14, 2013
Paper No: OMAE2013-10775
.... The vessel speed has been relatively low in average and well below the service speed, still the effect of springing and whipping has been significant on the fatigue and extreme loading. Previously, results from the strain sensors have been presented versus the fatigue and extreme loading on a general level...

Paper No: OMAE2013-10742
... A large blunt vessel was designed for a longer target life than usual in world-wide trade. Due to experience with whipping and springing, special attention to these effects was also made during the design and approval in order to ensure satisfactory strength of the vessel. The vessel...

Paper No: OMAE2011-49366
... It is well known that ships vibrate due to waves. The wave induced vibrations of the hull girder are referred to as springing (resonance) and whipping (transient vibration from impacts). These vibrations contribute to the fatigue damage of fatigue sensitive details. An Ore Carrier of 400 000 dwt...

Paper No: OMAE2011-49370
... Many large and ultra large container vessels have entered operation lately and more vessels will enter operation in the coming years. The operational experience is limited and one of the concerns is the additional effect of hull girder vibrations especially from whipping (bow impacts), but also...

Paper No: OMAE2011-49378
... Large container vessels are known to vibrate heavily in head sea storms due to its flexible hull girder, pronounced bow flare and high vessel speeds. Strong vibrations are mainly excited by bow impacts causing transient vibrations referred to as whipping. This whipping response increases both...

Proc. ASME. OMAE2010, 29th International Conference on Ocean, Offshore and Arctic Engineering: Volume 2, 123-131, June 6–11, 2010
Paper No: OMAE2010-20124
... Wave-induced vibrations, also known as whipping and springing, are defined as the high frequency response of ship structures. In this paper, the fatigue damage caused by whipping and springing is presented by investigating the amidships section of a 2800 TEU container ship that operates...

Proc. ASME. OMAE2009, Volume 4: Ocean Engineering; Ocean Renewable Energy; Ocean Space Utilization, Parts A and B, 51-62, May 31–June 5, 2009
Paper No: OMAE2009-79127
... 22 02 2010 Ships vibrate due to waves, and these wave induced vibrations can not easily be avoided by moderate changes to the hull lines. The waves may cause the whole hull girder to vibrate due to springing (resonance) and whipping (transient response), which increase the fatigue...

Proc. ASME. OMAE2008, Volume 5: Materials Technology; CFD and VIV, 731-737, June 15–20, 2008
Paper No: OMAE2008-57385
.... Hull girder whipping was analyzed to investigate dynamic amplification of structural stresses. Short-duration impact-related slamming loads excited the ship structure to vibrations in a wide range of frequencies. Excitation of the lowest fundamental eigenmode contributed most to additional stresses...
