In this paper, two methods to calculate the natural frequency of trapezoid stiffened plate in water are proposed. The results calculated by two methods are almost same, and have a good agreement with experimental results. A method to estimate the non-dimensional added mass coefficient of trapezoid plate simply supported or clamped along all edges is also proposed. The added mass coefficient of stiffened plate is estimated from the equivalent plate of which weight is equal to that of stiffened plate. The estimated results for the rectangular stiffened plate have a good agreement with calculated ones, but it can be seen a little discrepancy for the trapezoid or triangular stiffened plate.
