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.
Towing tank, St. John's
Tests performed in this facility include:
- Testing in calm water, waves
- Resistance and propulsion
- 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
