Limitation of loading and unloading operations in harbours due to ship motion
Konferensbidrag (offentliggjort, men ej förlagsutgivet), 2005
Motions of moored ships in harbours are excited by winds, currents, waves, seiches, tides, passing ships, and cargo handling. This lecture will describe the properties of these excitations as well as the mechanics of the motion response of the ships. Firstly, however, the recommended allowed limits of motions for safe working conditions of various ship types, from pleasure boats to fishing vessels and large bulk carriers, will be described. Such recommendations were presented by PIANC (1995) and the Nordic Council (1986). Following this, a theoretical study of the motion of a ferry at berth in the Port of Visby will be presented, which contains some novel ideas. Lastly, results and animations from some ongoing developments at Chalmers University of Technology on wave computations over large areas with complex topography will be presented.
