TQC has made the next evolutionary step in hull roughness surveys. Surpassing the industrial standards with an easy to operate 4-way directional push button, graphical representations, storage of data in multiple batches, and survey reports in Microsoft Excel®. The whole system fits into a small-sized waterproof rugged casing that can carry on travel luggage and benefits your overseas travel plans.
Controlling the roughness of a ship’s hull plays an important role in the operating costs of a vessel. The roughness of a ship’s hull increases due to corrosion, pitting, plate undulation, mechanical damage, dry spray, and above all biofouling. Proper maintenance and the correct application of high-end anti-fouling coatings reduce the hydrodynamic effects and will lead to significant savings on fuel consumption and CO2 emissions.
The hull roughness is measured during in-docking and out-docking. The Hull Roughness Gauge measures the AHR value (Average Hull Roughness) of seagoing vessels. AHR is the ‘mean’ of all the vessel’s hull roughness readings and is the measure against which the ship’s performance is correlated.
The TQC Hull roughness Gauge consists of a Control Unit and a Sensor unit.
The Hull Roughness Control unit can be operated with just one hand, a 4-way directional push-button operates an intuitive menu on a large illuminated display. The neck strap keeps the users’ hands-free when required.
The Sensor unit is equipped with three non-slip wheels and a carbide-tipped stylus and is moved over the ship’s hull in a horizontal way collecting series of measurements. A set of LEDs indicates the status of the instrument, so operation is possible without observing the control unit.
Statistics, time/date, and location of each series and the average hull roughness are automatically calculated and stored in the Control unit. Using the supplied USB-cable and software you instantly create inspection reports in Microsoft Excel. Your own company logo and or -details can be incorporated to restyle your reports.
