In this article the authors propose a change in approach when providing information included in maneuvering documents on the squat effect of a ship. The development of ships which is aimed at increasing the loading capacity contributes to the increase of their draft and construction dimensions. This fact renders it necessary to develop ports and to interfere in the bathymetric layer of the basin,...
The reduction of the distance between ship floor and seabed, while the ship is moving forward, is called squat. In this research, squat is determined for vessels with Series-60 hull forms in various depths by experimental methods and then different numerical methods are employed for squat modeling. For this reason, a set of facilities for testing the ship movement in shallow waters is prepared. A...
A review is made of linear slender-body methods for predicting the squat of a ship in shallow open water, dredged channels or canals. The results are summarized into a general formula based on Fourier transforms, and the method is extended to cater to stepped canals. An approximate solution for canals of arbitrary cross-section is proposed.
