  • Open-water maneuvering

Towing Tank

  • Length 60 m
  • Breadth 5 m
  • Water depth 3 m

  • Linear (1st order Stokes wave) and nonlinear (Jonswap, Pierson-Moskowitz, ISSC, TMA spectra) waves
  • Wave height up to 0.35 m
  • Wave length 0.2-20 m
  • Wave frequency up to 2.8 Hz

The unmanned carriage can tow models 1-3 m in length. The maximum weight of the model is 200-250 kg and the highest speed is 5.5 m/s. The vibratory response and the deflection of the carriage at its midspan remain below 1.0 mm during test runs.
