Vessel Traffic Systems, Ship Handling and Ship Manoeuvring Capabilities

摘要

Man's awareness of the threat of technology to the environment but also the new technology in itself are promoting the implementation and legislation of Vessel Traffic Systems of various degrees of sophistication. In the strive towards shore-based control the limitations inherent in the dynamics of the ships are sometimes overlooked. The purpose of this paper will be to pinpoint some of these limitations and some of the ship handling problems built into new designs. Following a brief look at ship design parameters an approximation of reference is formulated for the basic relation between hull form, size and specific resistance of power. Characteristic numbers are used to describe operating hazard or control potentials as examplified by four representative ships. A new method is advanced for the rational description and comparison of fairway alignments as well as for the analysis of ship maneuvering history from prototype records or computer simulations.
