MATHEMATICAL MODEL TO PREDICT THE BEHAVIOR OF DEEP-DRAFT VESSELS IN RESTRICTED WATERWAYS

Presently deep-draft navigation channel analysis, design and review is based on empirically derived ratios of the design vessel's dimensions. Because of radical changes in vessel operation purposes and characteristics, these ratios can no longer be safely or economically applied. The mathematical model and related theory described in this report provide the engineer with a comprehensive tool in the design and review of deep-draft navigation channels. Through its use, he will be able to predict values of squat, bank suction forces and moments, equilibrium drift and rudder angles, and heights of ship-generated waves for varied channel configurations, ship positions and ship velocities. Through the determination of channel section configuration sensitivity, an optimal design both operationally and economically can be achieved.
