DynaSim - A PC Based Ship Maneuvering Simulator
DynaSim is a user-friendly ship dynamics simulator that incorporates Systems Identification Techniques to determine ship maneuvering characteristics. Once these parameters are known the simulator can accurately reproduce ship motion in the presence of waves, wind, currents, and obstacles or other ships. Multi-threading enables simultaneous simulation of multiple ships. The initial efforts to develop the technology were funded by Small Business Innovation Research (SBIR) awards from the National Science Foundation the Department of Defense (see the presentation on that site: Virtual Showcase) and The National Oceanic and Atmospheric Administration.

DynaSim is a user-friendly ship simulator that utilizes ship maneuvering characteristics to faithfully reproduce ship motion in the presence of:
-
- winds
- waves
- currents
- obstacles
- other ships....etc.
- Multi-threading enables simultaneous simulation of multiple ships.
- An auto-pilot following traffic regulation enables traffic simulation in harbors and waterways
Capabilities
DynaSim incorporates state of the art models of ship motion and is capable of executing real time simulations of ship maneuvers in complex environments in real or accelerated time.
DynaSim employs modular mathematical models for the various components of the ship (hull, propellers, rudders, thrusters) and environmental effects (wind, current, waves) and waterways (bottom, pier walls) to achieve a sophisticated and faithful mathematical model for ship maneuvers. These models are based on collective experience resulting from the development of several ship maneuvering software.
DynaSim runs on a Windows operating system and has a user-friendly interactive graphic interface. It achieves capabilities on par with expensive stand-alone full-mission simulators.
Applications
DynaSim is suitable for the following applications:
- Training of master pilots
- Traffic safety evaluation in harbors
- Safety study of vessel types, traffic densities, waterway geometries
- Harbor structures design
- Navigation channels design
- Port traffic planning
- Marine/navigation regulation development
- Tug operation optimization

DynaSim Simulation Modes
DynaSim' has three basic simulation modes:
- User controlled mode: in DynaSim the user controls the rudder, the engine, and any lateral thrusters through a graphic control panel to simulate the navigation of a ship.
- Standard maneuver mode: DynaSim can simulate a ship performing one of the classical maneuvers (turning circle, zigzag, spiral) recommended by the International Maritime Organization (IMO) for certification and evaluation of ship hydrodynamic characteristics and maneuverability.
- Computer controlled navigation mode: DynaSim' can model ship traffic in the open ocean or in a restricted environment. The behaviors of the auto-piloted ships along prescribed routes in the simulation are based on the U.S. Code of Conduct of Vessels. Traffic central parameters can also be adjusted by the user.
Environment Definition
Environmental conditions can be user input and drawn with a set of tool bars or can be read from an environmental data file.
