NEW THINKING IN SHIP GENERATED HYDRODYNAMIC FIELDS: INTRODUCING CONCEPTS FOR PREDICTING BANK SUCTION AND REJECTION

摘要

Whilst numerous papers have been written describing effects that vessels may experience when encountering one another or, indeed, when stationary but under the influence of a tidal stream or current, there is limited information on the causational dynamic that results in what we call 'interaction'. This paper is, effectively, a work of four parts. It begins by outlining current teaching on the subject of marine hydrodynamics theory and highlights its particular shortcomings. The second part introduces the Manchester Ship Canal as research venue and explains the benefits and peculiarities of the location. The paper then introduces new theories on ship-generated hydrodynamic fields and provides detailed practical explanations that will be recognisable to experienced ship-handlers. Finally, a new theory on the mechanics of bank suction and rejection, along with a means of predicting its occurrence, is proposed. The ultimate aim is achievement of safer 'close-quarters' navigation and more predictable ship-handling.
