Furthermore, the remote and often isolated locations of subsea assets pose logistical and operational challenges. Remote locations can necessitate extended travel times, specialised equipment, and skilled personnel, all of which contribute to the complexity and cost of inspections.

Subsea inspection activities are inherently dangerous. The underwater environment introduces risks such as strong currents, low visibility, and the potential for equipment malfunctions. Safety protocols and advanced training are essential to mitigate these hazards effectively.

Weather conditions also play a significant role in subsea inspections. Unpredictable weather patterns can disrupt schedules and impact the safety of divers and equipment, making it imperative to plan inspections meticulously and adapt to changing conditions.

Types of Subsea Inspection Equipment

Subsea inspection relies on a variety of specialised equipment, each tailored to specific tasks. Two key types of subsea inspection equipment are Diver-Operated Inspection Tools and Underwater Inspection Sensors.

Diver-Operated Inspection Tools are versatile, handheld devices used for close-up examinations of underwater structures. These tools provide real-time data and visuals, aiding in inspections and repairs. On the other hand, Underwater Inspection Sensors are automated devices designed for remote data collection in challenging subsea environments.

Diver-Operated Inspection Tools

Diver-Operated Inspection Tools are indispensable in the realm of subsea inspection, offering divers the means to assess underwater structures with precision and efficiency. One such tool, the Cygnus Underwater diver-held tester, is tailored for divers requiring reliable thickness measurements even in challenging conditions. This device excels at delivering quick and accurate metal thickness gauge measurements through coatings and heavy corrosion.

Another valuable tool, the Cygnus DIVE Underwater Tester, can be wrist-mounted, enabling divers to perform inspections underwater without the need for drydocking. Its large, bright display ensures visibility even in poor conditions, allowing divers to view critical data alongside their cameras. The inclusion of an A-scan display further aids in measurement verification, making it an invaluable asset in underwater Class inspections.

Diver-Operated Inspection Tools like these are vital components of subsea inspections, providing the equipment view necessary to maintain the integrity and safety of underwater structures and equipment.

Underwater Inspection Sensors

Underwater Inspection Sensors are crucial instruments in the world of subsea inspection, offering advanced capabilities for assessing underwater structures and equipment. Two notable examples from Cygnus Instruments are the Cygnus ROV & Mini ROV and the Cygnus ROV UTM.
