Study on Manoeuvring Criteria for Safety Assessment in Shallow Water
Journal Title: TransNav, the International Journal on Marine Navigation and Safety of Sea Transportation - Year 2017, Vol 11, Issue 3
Abstract
The necessity of verifying manoeuvring mathematical models in shallow water for studying the safety of ships using a ship-handling simulator is pointed out in this report. Several instances of verification of mathematical models in shallow water are introduced here based on measurements of motion conditions of full-scale ships and shallow water tank tests of models. Results of safety assessment tests of five manoeuvring phases are given using the verified manoeuvring mathematical models to discuss manoeuvring criteria in shallow water. Objective manoeuvring criteria for safety assessment in shallow water are proposed based on subjective judgement related to control margin assessed by more than 3,200 masters and pilots for over 325 simulation tests and by analysis of the study results of 15 full-scale ships.
