DAMPING DEVICE, DAMPING SYSTEM, VESSEL EQUIPPED WITH DAMPING SYSTEM AND DAMPING METHOD

摘要

A damping device includes a cable to be connected to a mass; a winch for hauling in and paying out the cable; a measurement system for measuring a cable motion relative to the winch and for measuring a cable tension in the cable; a control system for damping cable motion by driving the winch in dependency of the measured cable motion and the measured cable tension; a sheave to guide the cable from the winch to the mass, wherein the measurement system is configured to measure the cable tension by measuring a magnitude of a load on the sheave caused by the cable tension.
