Undamped Natural Period of Vessel evaluator uses Undamped Natural Period of a Vessel = 2*pi*(sqrt(Virtual Mass of the Ship/Effective Spring Constant)) to evaluate the Undamped Natural Period of a Vessel, Undamped Natural Period of Vessel is defined for undamped natural period whereas motion of ship in surge is assumed to be independent of other directions of motion. Damping is assumed to be small for low-frequency motions of ship in surge. Undamped Natural Period of a Vessel is denoted by Tn symbol.
