Zeeuw provides inwater surveys of vessels to inspect for issues like damaged propeller blades, hull damage from collisions or groundings, wasted anodes, and shell plating cracks or corrosion. The surveys look at hull roughness from factors like fouling or corrosion which increase drag and reduce fuel efficiency. Zeeuw offers standardized inspection methods and detailed reporting per vessel part with photos and video to interface with biofouling management plans and identify needs for underwater cleaning or repair work.
