Subsea Corrosion Inspection. No Dry Dock Required.
The QYSEA UTG delivers precise, non-destructive metal wall thickness measurements from a single exterior surface — mounted directly to your FIFISH ROV. Inspect ship hulls, offshore platforms, and subsea pipelines while assets remain fully in service, eliminating the cost and downtime of traditional dry dock inspections.

Non-Destructive Testing. Single-Side Access. No Dry Dock Required. The QYSEA UTG.
The QYSEA Ultrasonic Thickness Gauge (UTG) is a professional-grade NDT payload engineered for FIFISH PRO W6, E-Series, and X1 ROVs. Transmitting ultrasonic pulses through metal surfaces and measuring time-of-flight returns, the UTG calculates wall thickness and detects internal corrosion from a single exterior surface — on ship hulls, offshore platforms, subsea pipelines, and marine infrastructure — while assets remain fully in service. No dry docking. No physical intervention. No downtime.
Key Specifications
- Non-Destructive Testing (NDT) — Measures metal wall thickness and detects internal corrosion without cutting, drilling, or removing coatings
- Single-Side Access — Measurements taken from the exterior surface only; no access to the interior or opposite side required
- ROV-Integrated Payload — Mounts directly to compatible FIFISH ROV models for depth-capable, remotely operated inspection
- Compatible Platforms — FIFISH PRO W6, FIFISH E-Series, FIFISH X1
- Target Applications — Ship hull surveys, offshore platform structural assessments, subsea pipeline integrity, port and harbor infrastructure inspections
- Eliminates Dry Docking — Conduct full thickness surveys on active, in-water assets — reducing inspection costs and operational downtime significantly
