MARTE

  • Length 60 m, breadth 5 m, water depth 3 m

  • Linear (1st order Stokes wave) waves

  • Nonlinear (Jonswap, Pierson-Moskowitz, ISSC, TMA spectra) waves

  • Irregulaarsed lained (Jonswap, Pierson-Moskowitz, ISSC, TMA spectra)

  • 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 250 kg and the highest speed is 6 m/s. The vibratory response and the deflection of the carriage at its midspan remain below 1.0 mm during test runs.
