The present invention relates to a maritime hydraulic impact-absorbing device for absorbing forces generated from an impact between a vessel having a speed and another structure which is either floating or fixed to a seabed. The impact-absorbing device comprises a base part having a first end and a second end and a connection point, the base part being adapted to be securely connected with the vessel or structure, and the base part having a longitudinal extension; at least one hydraulic cylinder having a first cylinder end and a second cylinder end, the first cylinder end being connected with the connection point of the base part, and the second cylinder end being connected with a movable impact face, whereby the movable impact face is adapted to be moved in a first, substantially horizontal direction when the second cylinder end of the hydraulic cylinder moves in the first horizontal direction, and is adapted to be moved in a second, substantially horizontal direction when the second cylinder end of the hydraulic cylinder moves in the second horizontal direction; and a hydraulic accumulator fluidly connected with the hydraulic cylinder. A first throttle valve is arranged between the hydraulic cylinder and the hydraulic accumulator, the first throttle valve being adapted to provide a pressure drop of a fluid flowing from the hydraulic cylinder to the hydraulic accumulator. The present invention furthermore relates to a vessel comprising a maritime hydraulic impact-absorbing device, a method of damping an impact between a moving vessel comprising a maritime hydraulic impact-absorbing device and another structure which is either floating or fixed to a seabed and an offshore personnel transfer system for transferring personnel between a vessel and an offshore wind turbine.
