DP HIL

Program view

DP HIL test

  • Support User friendly Contents
  • Consist of “Operator View” and “Monitoring Screen”, each program is for tester and owner respectively
  • Various sensors, power, thrust and signal can be tested using 60 different test items
  • DPC control state can be tested using signal modulation ( noise, bias, slope and direct signal)
  • All of test result data can be plotted with graph, and can be analysis
  • Vessel motion can be measured at continuously various sea state
  • Vessel’s limitation can be tested through dynamic positioning
  • Monitoring screen just show operator state, various signal, power, sensor and motion of vessel
  • Especially, Monitoring screen include 3D motion engine that can describe totally vessel motion at glance
  • Motion Engine implement reality sea state(i.e. wave direction and height) using state of the art graphics technique
  • All the other external conditions assume stable when DP controller test be implemented.

Test scope

Validation test

  • Thrust, power. Moment, and scaling testing for the propulsion system
  • Ocean current estimate in the DP control system
  • Wind force configuration
  • Station-keeping performance for different environmental conditions
  • Station-keeping and reference model performance during set-point changes
  • Offset compensation test for pos-ref sensors

Functional test

  • Wind force feed-forward
  • Capability Analysis
  • Station-keeping in all combinations of selected pos-ref and head-ref systems
  • Joystick modes
  • DP controller settings
  • Blackout prevention, load reduction
  • Follow target mode
  • Backup system monitoring and control - Backup DP switch1
  • Motion Prediction Analysis
  • Positioning control modes
  • DP backup system positioning test
  • etc.

Failure test

  • Signal failures on feedback signals from a thruster - Thruster
  • Electro/mechanical failures on a thruster - Thruster
  • Signal failures on VRU roll and pitch signals - VRU
  • Signal failures on a wind sensor speed and direction signals - Wind sensor
  • Signal failures on draught sensor signal - Draft sensor
  • Signal failures on HPR position signal - HPR
  • Failures in HPR flags and status indicators - HPR
  • Failures in DGPS flags and status indicators - DGPS
  • Signal failures on DGPS position signal - DPGS
  • etc.

DP HIL Test Simulator configuration

  • Development Tool : MATLAB, Visual Studio 2012, Unity3D
  • Development environment : MATLAB, .Net Framework 4.0,
    Unity 4
      - Programming Language : Simulink, C++, C#
  • Program Overview
    • 1. Develop features that communicate with analysis engine
    • 2. Develop Graphic Builder
        - drawing, create various event etc.
    • 3. Develop Real time interface
        - Interface which communicate with DP every 0.1 sec
    • 4. Develop Virtual VM
        - Create event for performing HIL Test
    • 5. Develop 3D visualization engine
        - Owner can monitor DP operation and control viewpoint of
          the vessel
