79278 - Development of an Online Ship Simulator to Represent the Dynamic Ship Responses in Regular Waves Using an Inertial Measurement Unit 

Nowadays, it has been observed a vertiginous growth of  technological implementations in the naval and offshore industry, implementations such as, online ship simulators that represents the state of the vessel in real-time for a certain sea conditions, motion amplification methods to monitoring vibrations of the ship propulsion system, virtual shore stations to control autonomous vessels, among others. This work presents the implementation of an IMU system in a scaled-down vessel with the purpose of observing the dynamic responses of a ship in an online simulator called ShipSim coded in JavaScript. The implementation considers the responses of the ship in its six degrees-of-freedom and its behavior in  regular waves. The simulator responds to a parametric variation, which considers the direction, amplitude, period of the waves, among other geometric parameters. The scaled-down model of the vessel is fabricated on a 3D printer and is designed to place the IMU system at the geometrical center of the vessel. The IMU is an 6DOF ACEINA OpenIMU300ZI which is used to measure the ship motions. In addition, real-time results of the different movements of the scaled-down vessel in the time domain are displayed, which are observed in the simulator in the form of time-series graphs.
