This is caused primarily by the synchronization of the relutive period of the seas, as they strike the vessel, with the vessel’s nut~rdl period for pitching or rolling.
Web3.2 Synchronous rolling motion Large rolling motions may be excited when the natural rolling period of a ship coincides with the encounter wave period. In case of navigation in following and quartering seas this may happen when the transverse stability of the ship is marginal and therefore the natural roll period becomes longer. WebMay 12, 2024 · Synchronous Rolling & Pitching When the ships roll period is equal to that of the apparent wave period, each roll is boosted by the wave and a condition of synchronous rolling is set up. An alteration of course rapidly helps to change the apparent wave period. Heavy rolling places high stresses on the transverse structure of the ship.
