The present invention relates to an assembly for installing a pile (2) in a seabed (3), the assembly comprising a vessel (23) comprising a positioning system for keeping the vessel (23) at an installation location relative to the seabed, the positioning system (5) having a positioning stiffness (7); a pile guiding system configured to guide the pile (2) during installation thereof, the pile guiding system comprising a base (9) provided on the vessel; a first guiding device connected to the base, the first guiding device being configured to accommodate the pile during installation thereof; a resilient member (11) for providing a resilient connection between the vessel (23) and the pile during installation thereof for allowing relative motions between the pile (2) and the vessel (23), the resilient member having a connection stiffness, wherein the resilient member (11) is configured and intended to keep a natural period of a pivoting movement of the pile about the seabed caused by waves during installation thereof longer than a dominant wave period of a wave spectrum at the installation location by providing the resilient connection with a low connection stiffness.
