Simulating global ship vibration can be split into three steps: firstly, the computation of the dry elastic vibration of the ship structure, secondly determination of the hydrodynamic pressures caused by a given time harmonic velocity distribution on the outer shell and thirdly, the solution of the coupled vibration problem by considering the interaction of fluid and structure. In this paper various approaches for the solution of the third problem for large models are compared and discussed. They are based on reduction methods for the hydrodynamic mass matrix and make use of fast solution methods for the exterior fluid problem for given velocity distributions of the shell. A numerical example is used to assess the accuracy and the speed of the solution procedures.
