The ship’s dynamic under keel clearance as an element of port safety management

The safety of a ship manoeuvring within a port area mainly depends on its under keel clearance. In many cases there is a need to accommodate ships larger than those the port has been designed for. This can be achieved by modernizing some components of port water areas or by changing operating conditions. This article will examine the components of some methods of under keel clearance determination. Their verification has been proposed.
