D SIMYNA©D , IYNAFLOW NC.Research & Development in Applied Scienceshttp: www.dynaflow-inc.comA PC BasedShip Maneuvering SimulatorCapabilities? D SIM incorporates state of the artmodels of ship motion and is capable ofexecuting real time simulations of shipmaneuvers in complex environments in realor accelerated time.D SIM employs modular mathematicalmodels for the various components of theship (hull, propellers, rudders, thrusters) andenvironmental effects (wind, current, waves)and waterways (bottom, pier walls) toachieve a sophisticated and faithfulmathematical model for ship maneuvers.These models are based on collectiveexperience resulting from the developmentof several ship maneuvering software.DYNASIM runs on a Windows operatingsystem and has a user-friendly interactivegraphic interface. It achieves capabilities onpar with expensive stand-alone full-missionsimulators.YNAYNA©©©??Definition??D SIM is a user-friendly ship simulator thatutilizes ship maneuvering characteristics tofaithfully reproduce ship motion in the presenceof:windswavescurrentsobstaclesother ships....etc.Multi-threading enables simultaneoussimulation of multiple ships.An auto-pilot following traffic regulationenables traffic simulation in harbors andwaterwaysYNA©??????DYNAStatus indication dialsSIMA©ApplicationsD SIM is followingdesignYNA©suitable for the applications:Training of master pilotsTraffic safety evaluation in harborsSafety study of vessel types, traffic densities, waterwaygeometriesHarbor structuresNavigation channels designPort traffic planningMarine/navigation regulation developmentTug operation optimization????????Advantages & FeaturesD SIMAdvanced mathematical modeling of ship maneuveringhydrodynamicsEnvironmental effects: wind, wave, current, bathymetry,...User input ship data fileYNA©includes the following:Ship characteristics: type, geometry, twin screw,bow/stern thrusters, tugs,..Simulation of IMO standard ship maneuversAutopilot with collision avoidanceConfigurable preplanned routes and ship schedulesHarbor/waterway system safety metricFuel consumption calculationTug operation simulation by a user controlled tugboatand/or by tabulated force vectorsHuman errors and delaysGraphic User Interface with user control input through akeyboard, a mouse, and a joystickTechnical support and flexible customization?????????????Ship control panelRoute properties panelShip definition panelD SIM Simulation ModesYNA ©D SIMin D SIM the user controls the rudder, theengine, and any lateral thrusters through a graphic control panel tosimulate the navigation of a ship.D SIM can simulate a ship performingone of the classical maneuvers (turning circle, zigzag, spiral)recommended by the International Maritime Organization (IMO) forcertification and evaluation of ship hydrodynamic characteristics andmaneuverability.D SIMYNAYNAYNAYNA©©©©has three basic simulation modes:can model shiptraffic in the open ocean or in a restricted environment. The behaviors ofthe auto-piloted ships along prescribed routes in the simulation arebased on the U.S. Code of Conduct of Vessels.
