Case Studies
3x 32' DIESEL TANKS | MINING SITE
An international mining company had a need to inspect 5 diesel tanks at one of their domestic sites. The tanks were used as a back up power supply, but had never been inspected and had no tank drawings. Completing the inspection was critical, as tank failure could have major impacts, and the mining facility wanted to find an online solution.
Case Studies
120' GASOLINE TANK | MIDSTREAM TERMINAL — SIDE LAUNCH
A terminal operator had a critical 120-foot gasoline tank with an internal fiberglass liner that could not be taken offline for extended periods. Inspection was needed by year-end, and the fiberglass liner created a unique technical challenge: conventional UT would not penetrate the coating.
Case Studies
120' NAPHTHA TANK | MIDSTREAM TERMINAL — SIDE LAUNCH
A major terminal operator did not want to drain product below the manway level to install the manway adapter and valve required for a standard side launch inspection — but still needed an onstream API 653 inspection completed. The site worked with Square Robot to complete installation through a different avenue.
Case Studies
40' MGO DIESEL TANK | REFINERY — SIDE LAUNCH
A Singapore refinery had several tanks scheduled for robotic inspection to avoid the significant operational disruption that out-of-service inspections would have caused. For this 40-foot MGO diesel tank, Square Robot worked jointly with their local regional partner to deliver the inspection.
Case Studies
70' STYRENE TANK | PETROCHEMICAL — SIDE LAUNCH
A refinery had a 70-foot styrene monomer tank that was a candidate for robotic inspection — however, styrene had not previously been tested for compatibility with Square Robot's systems.
Case Studies
70' LUBE OIL TANK | REFINERY
A Texas refinery operated a 70-foot diameter lube oil tank that was subject to heightened quality control and assurance standards. Taking the tank out of service for a conventional API 653 inspection would have been extremely disruptive to production operations and costly to manage.
Case Studies
30' DIESEL TANK | POWER PLANT
A cogeneration power plant relied on a 30-foot diameter diesel tank to supply fuel for its turbines. A full API 653 out-of-service inspection would have required temporary storage equipment, taken the tank offline, and forced the manufacturing plant that the facility powered to shut down temporarily as well.
Case Studies
150' #2 FUEL OIL TANK | POWER PLANT
A power plant client required an on-stream API 653 inspection of a 150-foot diameter red-dyed #2 fuel oil tank. Initial concerns included potential sediment build-up that could interfere with robotic inspection, and a lack of crane access around the tank perimeter.
Case Studies
118' DIESEL TANK | MIDSTREAM TERMINAL — MOZAMBIQUE
A fuel storage terminal in Mozambique required an inspection of their primary diesel storage tank. The terminal's remote location meant that taking the tank out of service would have created severe logistical and supply chain disruptions, with impacts far beyond the facility itself.
Case Studies
112' DIESEL TANK | POWER PLANT
A power generation facility relied on a single 112-foot diameter diesel tank to supply backup generators. With no secondary storage available, taking the tank out of service for a conventional API 653 inspection would have required alternate storage to be brought in, making it a costly and lengthy endeavour.
Case Studies
78' RENEWABLE DIESEL TANK | BIOREFINERY
A biorefinery facility in Geismar, Louisiana required an API 653 inspection of its renewable diesel storage tank.
Case Studies
150' DIESEL TANK | MIDSTREAM TERMINAL
A major midstream terminal operator had a 150-foot DOT diesel storage tank that the terminal said would require 7 months for a conventional out-of-service inspection. The operator sought to eliminate months of downtime and hundreds of thousands of dollars in cleaning and mobilization costs by utilizing robotic inspection technology.
Case Studies
211' JET A1 TANK | MIDSTREAM TERMINAL
A large fuel terminal in Guam required an online API 653 inspection of a 211-foot diameter jet fuel tank, combined with a full tank calibration survey. The terminal's critical operational role meant that any downtime would have far-reaching consequences.
Case Studies
115' JET A1 TANK | COMMERCIAL AIRPORT
A commercial aviation operator had an airport fuel storage tank due for an API 653 inspection. The airside environment created unique access and permitting challenges, particularly around crane operations, which require FAA approval, making a traditional out-of-service inspection extremely costly and time-consuming.
Case Studies
217' JET A1 TANK | REFINERY
A critical jet fuel tank at a major refinery could not come offline without significant operational impact to the terminal. The client had a strict 5-day window to complete a full API 653 inspection of the 217-foot diameter tank, a challenging constraint for any conventional approach.
