BEHAVIOUR OF LARGE TANKERS IN SHALLOW WATER IN RELATION TO THE DIMENSIONS OF AN APPROACH CHANNEL

By making approach channels in relatively shallow coastal areas, existing harbours and trans-shipment sites can be reached by bigger (deeper draft) ships. In this paper some aspects influencing the design of such a channel will be discussed, especially the choice of direction, width and depth of the channel in relation to the behaviour of the expected ships and to the environmental conditions. After some years of sailing practice a re-consideration of the originally chosen dimensions may lead to adjustments in the configurations. Therefore it will be of advantage to realize the channel and the ship operations in stages. In this way the latest insights into the interaction between the channel under construction and the sailing behaviour of the ships can be incorporated in the next stage. The paper is not related to a specific location and therefore only a few aspects are discussed. To illustrate the paper some results of design studies for the Europoort channels are given in relation to operational data with tankers up to 250,000 dwt in the channels.
