Other NDT Sensors and Testing Methods

While visual data is common, other types of data may be necessary for comprehensive inspections. Non-Destructive Testing (NDT) methods and specialized sensors are often used to gather this information.

Ropes and Drones Case Study

A recent inspection by Premium Inspection & Testing showcased the effectiveness of combining drones and rope access. The team used a drone to collect initial visual data inside a coke drum, followed by manual inspections using ropes to gather more detailed information.

This approach not only saved time but also reduced costs significantly, highlighting the value of integrating multiple tools into a single inspection strategy.

Here are some examples of NDT methods and sensors used in inspections:

• Thermal data. Thermal sensors detect heat patterns, useful for identifying leaks or overheating areas.

• Ultrasonic data. Ultrasonic testing uses sound waves to detect internal flaws or measure material thickness.

• Radiography data. X-ray or gamma-ray imaging helps identify internal defects in materials.

• Eddy current data. Eddy current testing detects surface and near-surface flaws using electromagnetic induction.

These tools are essential for ensuring the structural integrity of assets across various industries.

Robots

Robotic solutions have revolutionized the inspection industry, offering safer and more efficient ways to collect data. There are three main categories of robotic tools used by inspectors:

• Drones / Aerial Robotic Solutions

• Ground-Based Robotic Solutions

• Submersible / Underwater Robotic Solutions

Drones / Aerial Solutions

Drones have become a staple in industrial inspections due to their ability to reach difficult-to-access areas. They are particularly useful for visual inspections, though some models can also capture thermal or other sensor data.

Why use RVI tools?

There are several advantages to using drones for inspections:

• Safety. Drones reduce the need for human exposure to hazardous environments.

• Savings. Using drones can cut inspection costs significantly.

• Reduced downtimes. Drones speed up the inspection process, minimizing operational downtime.

Indoor vs. outdoor drones

Indoor drones are designed for confined spaces and feature collision-resistant designs. Outdoor drones, on the other hand, are built for open environments and lack the same level of protection.

Outdoor drones, such as the DJI Matrice 300, are popular for large-scale inspections.
