Criteria for the mooring forces of ocean-going ships in locks

The criterium applied in this paper is that the ratio of the hydrodynamic force and the ship's displacement should not exceed a distinct value. From investigations concerning the representative mooring outfit of ships, their normal behaviour in the lock and the influence of external hydrodynamic forces acting on the ship when berthed, criteria for the mooring forces have been determined for ships up to 150,000 dwt.
