The Hull Roughness Gauge is used in the Marine Industry to control the roughness of a ship’s hull, this instrument plays an important role in the operating costs of a vessel. It measures the AHR value (Average Hull Roughness) of sea going vessels, which is the ‘mean’ of all the vessel’s hull roughness readings and is the measure against which ship’s performance is correlated.
The roughness of a ship’s hull increases mainly due to corrosion, pitting, plate undulation, mechanical damage, dry spray and above all bio fouling. Proper maintenance and the correct application of high-end anti-fouling coatings reduce the hull roughness which will lead to significant savings on fuel consumption and CO2 emissions. The hull roughness is measured during in-docking and out-docking.
