Mooring Systems are used to hold buoys, ships or plat forms in position during certain operations. This dominantly refers to the three translational degrees of freedom. These mooring systems can spread out over many kilometers. They consist of anchors, heavy chains and nylon ropes or steel cables, which are attached to the moored object. A displacement of the vessel with respect to the equilibrium position causes lowering or lifting of the heavy chain links from the ground and thus results in a changed restoring force.
