These sheltered areas have abundant marine life which in general is affected by noise pollution. Sound generated by takeoff / landing of an airplane from a floating airport is the area of interest in this study. T with numerical analysis being relegated to a supporting role and their results greeted costly and hence numerical methods are used. We propose a simple numerical method for calculating the sound radiation from floating structures due to such moving loads. The effect of moving load, current in the fluid below and axial loading has been studied. In developing the expression, Fourier transform methodology for a Timoshenko-Mindlin plate is utilized. Key words: Moving Load; Floating Airport; Timoshenko-Mindlin plate; Heavy fluid- loading; Sound radiation; Mean flow; Inplane loading. ISSN: 2278 0211 (Online)
