dc.description.abstractThis thesis computationally analyzes the effect of commonly occurring ship load variations and wave induced bending moments on hull girder flexure. The deflection of the hull is used to determine the impact on the alignment of the vessel's combat system. Simple beam theory is applied for the structural portion of the analysis. Wave induced bending moments are determined by using a quasi-static approach with regular waves. Calculations and results are presented for theFFG7 calss of U.S. Navy frigates. It is shown that commonly occurring load conditions produced no significant problems with the alignment of the ship's combat system. The effect of waves can be more significant. Deflections of up to 9 arc minutes are predicted between elements of the combat system in seastate 6. This is out of the elements' alignment tolerance and could affect the operability of the systemen_US
