Development And Application Of Simulation Platform For Ship Maneuvering

Ship maneuverability is considered as an important index and relates closely to the navigation safety and economy. As the navigation abilities have been enhanced quickly,the transport quantity of ships increase so fast that the navigation conditions of waterway and navigation structures must be challenged with difficulties due to enlargement and rapid development of ships. In addition,it is obvious that there are more and more difficulties for ship maneuvering because of the complexity of navigation condition and distinct discrepancy of drivers.Thus,the attention of navigation safety has been largely paid.Therefore,in order to insure the safety of waterway and ships, it is more and more important for the researches on ship maneuvering.According to the reseaches results on hydrodynamics, the simulation platform for ship maneuvering has been developed based on the ship maneuvering motion mathematical model in this paper.The main reseach work and relevant results are listed as follows:①The relevant research results and successful experiences and existing problems get investigated and concluded. Also,the research method was analyzed.②The simulation code has been obtained based on fortran by building the flow mathematical model with two dimension and corresponding verfication have been carried out.The results showed that the simulation precision can meet with the need of practical engineering.③Based on the ship maneuvering motion mathematical model,the simulation platform has been developed. In addition, there are menus,tools and windows with style of Microsoft Windows on this platform which can achieve visualization and dynamic display.④Various tests of ship maneuvering simulation including turning circle, zig-zag maneuvering on the practical engineering reach are carried out by this platform, which showed that the results are satisfactory by analyzing the simulation precision and can be applied with the practical engineering studies.⑤Based on the reasonable flow and ship motion mathematical model, the tests of ship maneuvering simulation on the Caiyuanba reach were achieved on this platform and ship maneuvering characteristics on typical water area were investicated.The results showed that the platform can be deemed as a tool that forecasts ship maneuvering under some certain conditions. Furthermore, it is foreseen that the platform will be more heavily used as its development becomes more sophisticated and user friendly.
