Comparative analysis of methods for calculating the ship’s squat

As ships get bigger, channels have to be dredged deeper and maintenance costs increase. Dredging costs would be minimized if ship squat predictions could be improved for every ship using the channel. The additional sinkage and trim of ships due to speed, also called ship squat, is an important phenomenon to consider in the design of fairways. Although many ship squat formulas exist, none of them is able to predict squat with satisfactory accuracy for all ship types and channel configurations. Each formula has certain constraints based on the ship and channel conditions for which they were developed. No one formula works best for all channel and ship types. Thus, it is necessary to examine the squat predictions with more than one formula and compare the results based on the type of ship, channel, and formula constraints.
