In the framework of the refined theory, which takes into account transverse shear deformation and all inertial components, the solution of the problem on the steady state vibration of the orthotropic closed cylindrical shell with the arbitrary number of cutouts of the arbitrary geometrical form and location is constructed. External boundaries of the shell are of the arbitrary geometrical configuration. Arbitrary harmonic in time boundary conditions are considered on the external boundaries of the shell and on the contours of the cutouts. The solution is built on the basis of the indirect boundary elements method and the sequential approach to the representation of the Green's function. The boundary value problem is reduced to the system of algebraic equations.
