摘要

Working closely with Marine Service GmbH, the Hamburg-based consultancy, Hatlapa has developed an advanced mooring system primarily intended for use with larger oil and gas tankers. This is specially designed for use on ships required to load and unload at piers or floating platforms outside sheltered coastal waters, where they may be exposed to substantial forces from wind, waves, and currents that can produce significant motions. As the company points out, excessive vessel motions can lead to an interruption in loading and unloading or, in a worst-case scenario, to the disconnection of loading arms and hoses. Larger vessels can create high dynamic loads on mooring lines, while cyclic tensioning and de-tensioning during vessel motions can cause fatigue in mooring lines in a relatively short period of time. Hatlapa highlights, however, that the cause of excessive movement of moored vessels is not just the magnitude of the forces acting on the vessel, but also of the cyclical component of these forces.
