Ship Squat and Interaction

This book provides detailed explanations of ship squat and interaction, using worked examples, diagrams, case studies and the author’s personal computations and time-proven formulae.

Ship squat and interaction are major concerns for ship handlers, particularly when operating in shallow waters. This book examines the theory of these forces, how they compromise ship safety and the actions to take to avoid grounding or collision.

The first section of the book lists the signs that indicate when a ship has entered shallow water conditions. It describes methods of measuring squat and looks at the effect of speed on the squat value. Detailed guidance is provided on calculating squat and mean bodily sinkage, as well as the actions a ship can take to reduce squat. The guide provides 15 worked examples that guide the reader through each step of squat calculation.

The second section describes the causes and effect of interaction and identifies the situations in which it is likely to occur. It contains case studies that analyze the causes of various ship incidents related to interaction.
