Cygnus Underwater: Advanced Ultrasonic Thickness Gauge for Subsea Inspections

Cygnus Underwater is engineered for precision in the most demanding underwater environments - whether you’re inspecting offshore platforms in the open ocean or conducting maintenance on inland waterways.

Cygnus Underwater is engineered for precision in the most demanding underwater environments. Whether you’re inspecting offshore platforms in the open ocean or conducting maintenance on inland waterways, this next-generation ultrasonic thickness gauge delivers unmatched accuracy, reliability, and ease of use.

A Major Leap Forward in Underwater Thickness Measurement

The latest addition to the Cygnus diver range, the new Cygnus Underwater represents a significant advancement over its predecessor. Packed with innovative features, it is purpose-built to operate seamlessly in diverse conditions – ensuring greater measurement accuracy, enhanced usability, and robust performance in harsh subsea environments.

Why Cygnus Underwater Stands Out
• Multi-Mode Operation: Ideal for measuring through protective coatings and heavily corroded metals.
• Deep-Coat Capability: Accurately measures through coatings up to 20mm thick.
• Depth Sensor Integration: Provides live depth readings automatically tagged to each measurement.
• Intuitive Diver Interface: Three quick-access function keys and four dynamic screen views for instant results.
• High-Visibility Display: Large colour LCD screen optimized for low-light and low-visibility conditions.

Offshore Applications

Marine environments are among the harshest on earth, and Cygnus Underwater is built to thrive in them. Offshore applications include:
• Offshore Platforms and Mobile Offshore Units (MOUs)
• UWILD and IWS Class Ship Surveys
• Subsea Pipelines
• Subsea Storage Tanks.

Corrosion is a constant threat offshore, especially on ship hulls near the waterline where salt spray accelerates deterioration. Cygnus Underwater enables Underwater Inspections in Lieu of Dry-Docking (UWILD) or In-Water Survey (IWS) surveys while vessels remain in transit, eliminating unnecessary dry-dock visits and reducing costly downtime.

Through-Coating Measurement for Corrosion Control

Ships and subsea structures often rely on protective coatings, but coatings alone cannot prevent corrosion entirely. Cygnus Underwater’s Multiple-Echo mode, approved by Class Societies, ensures accurate through-coating measurements. Combined with the Deep-Coat function, which measures through coatings up to 20mm thick, this gauge is the ultimate solution for coated vessels and offshore structures.

Inland Waterway Applications

Inland waterways span continents, from vast river systems in Asia to extensive canal networks in the US. Cygnus Underwater is equally effective for:
• Civil Engineering Projects (Bridges, Pipelines)
• Canal Locks and Dams
• Workboat and Barge Hull Inspections
• Marine Structures (Piers, Jetties).

Its streamlined design ensures quick, safe operation in unfamiliar environments. Features like intuitive menus, fast function keys, and real-time A-scan display allow divers to focus on the job – not the equipment.

Smart Features for Professional Divers
• Four Screen Views: Basic readings, live A-scan, datalogging, and more.
• Automatic Depth Tagging: Every measurement includes precise depth data for easy reference.
• Enhanced Datalogging: Store and review measurements efficiently for compliance and reporting.
