THE PHYSICAL CAUSES OF HYDRODYNAMIC INTERACTION AND ITS EFFECTS

All ships must, at some time, navigate close enough to another ship, or to the sea bed, river bank, or other boundary, to experience hydrodynamic interaction. The Author, of the National Maritime Institute, examines in detail some aspects of this interaction in the light of work carried out at the Institute, with the object of providing a better understanding of the phenomena and of indicating the areas where they may lead to problems in ship-handling. The paper, which gives some emphasis to ships operations in shallow water, is arranged under the main headings: 1. Introduction. 2. Basic Hydrodynamics (Interaction--The Causes of Interaction). 3. Ship-Ship Interaction (Ships of Similar Size--Moored Ships--Ships of Dissimilar Size). 4. Ship/Bank Interaction (Ship on a Course Parallel to a Bank--Ship on a Course at an Angle to a Bank). 5. Some Ship-Handling Matters (The Effect of Speed--The Effect of Water Depth--Resistance and Squat--Rudder Effectiveness--Response of Helmsman and Control Gear--Areas of Safe Approach--Ships in Curved Canals).
