Hull Thickness Testing measures the structural integrity of a vessel's hull using ultrasonic gauges to detect corrosion or wear. UWILD surveys assess underwater hull conditions, including fouling, damage, and coating performance. Both are critical for ensuring maritime safety and regulatory compliance.

Hull Thickness Testing: Measures hull thickness using ultrasonic gauges; typical range 5-30 mm; material: steel, aluminum, or composite; grade varies by vessel class; no viscosity or buoyancy parameters.

Uwild Surveys: Focus on underwater inspections; size: adaptable to vessel dimensions; material: typically corrosion-resistant alloys; grade: depends on survey standards; no viscosity or buoyancy specifications.
