Beneath the Surface: How Nexxis is Transforming Buried Fuel Tank Inspections

Fuel is the lifeblood of industries worldwide, powering operations and keeping businesses running. Maintaining buried fuel reserves in optimal condition is essential, but inspecting them has always been a challenge. 

Traditional methods rely on confined space entry, manual visual assessments, and lengthy downtime – posing risks and inefficiencies. 

Nexxis offers a smarter alternative with advanced solutions that provide faster, safer, and more precise fuel tank inspections, ensuring reliability without disruption. 

 

The Problem with Traditional Fuel Tank Inspections 

Conventional fuel tank inspections rely on workers physically entering confined spaces, using basic tools to assess conditions, and making subjective judgments about structural integrity.  

The key challenges include: 

• High safety risks – Confined space entry poses serious hazards. 

• Disruptive downtime – Inspections take time, leading to operational delays. 

• Limited accuracy – Manual methods can miss critical flaws, increasing long-term costs. 

 

Nexxis’ Robotic Solutions 

At Nexxis, we have developed a range of robotic inspection tools that eliminate the need for human entry while delivering superior imaging and data analysis. 

 

Remote Visual Inspection (RVI) 

RVI is a non-destructive testing (NDT) method that allows for real-time assessments without disrupting operations. It removes the need for confined space entry, reduces downtime, and provides objective, high-quality data. In the below scenario, we captured images using our four pronged, electromagnetic crawler, Magneto. 

 

Ultrasonic Thickness Testing (UT) 

UT provides precise wall thickness measurements to detect corrosion and structural weaknesses. Using advanced UT probes, Nexxis’ robotic systems can compare current tank conditions to their original specifications, identifying wear and potential failures before they become critical. 

 

Phased Array Ultrasonic Testing (PAUT) 

For a more detailed assessment, PAUT detects and images defects such as corrosion pitting, cracks, and wall thinning. This technology ensures early detection of structural issues, allowing for proactive maintenance and repair. 

 

Laser Scanning 

Laser scanning provides comprehensive mapping of the tank’s internal surfaces, identifying micro-pitting and structural defects with high precision. It can be deployed manually or mounted to the Nexxis Hellcat Crawler for seamless automated scanning. 

A Safer, Smarter Future for Industrial Inspections 

Nexxis’ robotic solutions improve safety, reduce downtime, and lower operational costs. By removing the need for manual inspections, operators can ensure more efficient and reliable maintenance. With advanced imaging, automated scanning, and real-time data analysis, Nexxis is setting a new standard for buried fuel tank inspections.
