The UK BSRA (BISRA) has released the basic concept of a legitimate successor to the hull roughness gauge, which has been globally recognized for its necessity.
Managing the surface roughness of a vessel significantly impacts the operational costs of the ship. Corrosion, pitting, warping of steel plates, mechanical damage, and marine biofouling all lead to a considerable deterioration in surface roughness. Proper maintenance of the propeller and timely repainting with antifouling and fouling prevention coatings reduce hydrodynamic resistance, contributing not only to fuel efficiency but also to the reduction of CO2 emissions. The AHR value (Average Hull Roughness) measured by the "Hull Surface Roughness Gauge" is closely related to the navigational capability of the ship while it is in operation. 【Features】 ○ Composed of a control unit and a sensor unit ○ The control unit can be operated with one hand ○ The four-direction jog buttons, combined with a large display, allow for intuitive operation ○ Statistical data, time and date, and information on a series of hull positions where average surface roughness was measured are automatically aggregated and stored in the control unit ○ By using the included USB cable and software, inspection reports can be immediately created in Microsoft Excel For more details, please check the link.
