Towing tank

Research facility highlights

Deep enough to test underwater vehicles and equipped with a tow carriage fast enough to test high-speed vessels such as warships, the NRC's towing tank is used to simulate marine conditions and evaluate the performance of a range of marine systems including bulk carriers, patrol vessels, sailing yachts, ice breakers, and submarines among others.

Tests performed in this facility include:

  • Testing in calm water, waves
  • Resistance and propulsion
  • Seakeeping
  • Manoeuvering
  • Propeller open water
  • Hydrodynamic force measurement
  • Motion studies of moored and floating structures
  • Life-saving appliances and human factors testing

What we offer

At 200 m long, 7 m deep and 12 m wide, this tank is capable of testing ship models up to 10 m long and can also produce regular waves up to 1 m high and irregular waves up to a height of 0.75 m. The tank's carriage is a precision-controlled mobile laboratory that is used to follow self-propelled free-running models or tow rigidly-connected models at a maximum speed of 10 m/s. Wave absorption is provided by a parabolic beach and wind generation by a bank of eight fans.

The NRC's towing tank is 200 m x 7 m x 12 m

The capabilities of the towing tank are supplemented by unique pieces of equipment including a large amplitude planar motion mechanism for studying manoeuvring characteristics, a marine dynamic test facility capable of evaluating underwater vehicles in six degrees of freedom of motion and a sailing yacht dynamometer. Wake survey equipment and propulsion dynamometers are also offered, as well as flow visualization equipment and HD video.

Other test equipment includes:

  • Capacitance and sonic wave probes
  • Qualisys optical tracking
  • Precision gimballed towing dynamometers
  • Inertial measurement systems and propulsion control systems for free-running models
  • High-definition video that is synchronized with all digitally-recorded sensor data
