Abstract: A pile driver configured to drive a pile into an underwater bed includes a floatable body with a pile guide configured to guide the pile in a downward direction, and an actuator that is fixed to the floatable body and that is configured to drive the pile from the floatable body into the underwater bed. A method of driving a pile into an underwater bed includes the steps of: positioning a floatable body; arranging a pile in a pile guide configured to guide said pile in a downward direction; and driving the pile from the floatable body into the underwater bed by an actuator that is fixed to the floatable body.

Abstract: The present disclosure relates to a support device. The support device can include a hollow elongate member being in the form of a pile, a substantially fluid tight confined space within the hollow elongate member with at least a first seal at a distance above ground level, wherein a first fluid is arranged in the confined space, and at least one damping means is arranged in pressure connection with the first fluid in the confined space. Furthermore, the disclosure provides a method for the application of the support device.
