heal.abstract	This paper deals with the interaction of waves and current with a cylindrical bottom mounted structure piercing the free surface. The problem is formulated by applying linear potential theory and the solution is obtained using a perturbation expansion for the diffraction potential with respect to the normalized current speed. As the associated hydrodynamic problem for the perturbation potential involves the inhomogeneous form of the boundary condition on the free surface, a semianalytical formulation is used for the derivation of the solution. This method results in a Sturm-Liouville problem which requires the construction of a Green's function and the evaluation of an integral with an unbounded upper limit. © 2006 Civil-Comp Press.	en
