A hydraulic mooring cable holding device is provided. The device is designed to provide slack on a mooring cable when a ship moored along a quay rocks due to wind gusts. The device has a hydraulic cylinder with a piston in the hydraulic cylinder, a reservoir for hydraulic liquid and gas, a part of the hydraulic cylinder on a first side of the piston and the reservoir forming an operationally closed hydraulic circuit. A one-way valve is provided between the reservoir and the hydraulic cylinder on said first side of the piston, directed to selectively allow flow of the hydraulic liquid from the reservoir to the hydraulic cylinder. A relief valve is coupled between the reservoir and the hydraulic cylinder on said first side of the piston and directed to selectively allow flow of the hydraulic liquid from the hydraulic cylinder to the reservoir, when a pressure difference between liquid in the hydraulic cylinder and the reservoir exceeds a predetermined threshold. Thus, when the force on a cable due to rocking of the ship exceeds a threshold, the device pays out slack on the cable. When the force decreases sufficiently the device hauls back in the slack.
