Sea motions and accelerations

  1. Jun 5, 2015 #1
    Hi all,
    I have a question regarding to the ship motion at sea. Can a ship experience maximum roll acceleration and maximum heave acceleration at the same time? I need this answer to determine the worst loading conditions for my equipment on the ship. Thanks.

    There will be an angle of quartering the seas where roll and heave should maximize at bout the same time. However, I think heave will be stil higher with seas directly on the bow and roll with seas on the beam. Quartering the seas is usually gentlest on the vessel.
