This paper analyses the wave scattering generated by point pressure loads in the vicinity of infinite fluid-filled circular pipelines submerged in a homogeneous fluid medium. The pipeline has a constant cross-section and is modelled as a homogeneous elastic material. The three-dimensional (3-D) response is formulated in the frequency domain, and is obtained as a discrete summation of the 2-D solutions found for different axial wavenumbers. Time solutions are computed by means of inverse Fourier transforms. Complex frequencies are used to avoid aliasing phenomena.
