Tank Storage Industry Trends | A Look Back on StocExpo 2026

Lightning Eliminators & Consultants (LEC), headquartered in Boulder, CO, was on the ground at StocExpo 2026 for the 16^th consecutive year in Rotterdam, Netherlands. StocExpo is one of the premier events in the tank storage industry, attracting operators, solution providers, and others worldwide.

Mike McMahon (CEO) and Joe Lanzoni (VP Sales Engineering) represented LEC and our innovative lightning protection and prevention solutions.

This article shares their observations of the emerging trends, technologies, and concerns shaping industry conversations.

Downtime Is Still the Tank Storage Industry’s Biggest Pain Point

Across many conversations, the same challenges surfaced repeatedly:

• Delays in shipping channels
• Bottlenecks in loading and unloading
• Unexpected equipment or infrastructure failures

Operators are increasingly viewing these issues through a financial lens. With downtime costs often exceeding thousands of dollars per hour, even minor disruptions have major economic consequences.

That’s why solutions that proactively reduce operational risk, not just reactively respond to failure, are gaining traction. Prevention, not reaction, is where the industry is heading.

Firefighting Technology Is Getting Smarter

Fire protection remains a cornerstone of tank terminal operations, but the technology is becoming far more advanced.

At StocExpo 2026, there was a strong presence of firefighting solution providers showcasing systems like:

• Automatic foam deployment for floating roof tanks
• Integrated fire detection and suppression systems
• Faster-response containment technologies

These systems are designed not just to extinguish fires, but to prevent catastrophic tank loss and reduce costly overhauls.

The takeaway: fire protection is no longer just a compliance requirement; it’s a strategic investment in uptime and asset preservation.

Robotics Are Changing Tank Inspection and Cleaning

One of the most compelling areas of innovation is in robotic tank inspection and cleaning.

New technologies are making it possible to:

• Inspect tanks using robotic crawlers equipped with cameras
• Clean tanks with minimal or no human entry
• Reduce exposure to hazardous, confined, and flammable environments

These systems are becoming more reliable and more cost-effective, which is accelerating adoption.

The implications are significant:

• Improved worker safety
• Lower maintenance costs
• Reduced downtime during inspections and cleaning cycles

This is a clear example of technology solving both safety and economic challenges at the same time.

The Shift to Dome Roof Tanks (IFRTs), and a Dangerous Misconception

Globally, tank design is evolving, and new construction is toward dome roof (covered) tanks, otherwise known as Internal Floating Roof Tanks (IFRTs).

The primary driver is environmental:

• Reduced emissions
• Better vapor control
• Improved regulatory compliance

But this shift has introduced a subtle, and potentially dangerous, misconception:

Covered tanks are often perceived as “safe” from lightning risk.

They’re not.

While IFRT’s do have lower lightning-related risk compared to external floating roof tanks, they still have some risk of ignition from direct and nearby lightning strikes. Historical fire data shows that while external floating roof tanks experience more incidents, internal configurations still account for a meaningful number of fires, many of them linked to lightning.

The Standards Gap in Lightning Protection for IFRT’s

Part of the challenge lies in how standards are interpreted.

Both API and NFPA standards require shunts and bypass conductors for lightning protection for external floating roof tanks (EFRT’s), but not for fixed roof and internal floating roof tanks (IFRT’s).

This gap in standards can create a false sense of security. As a result, engineers may not specify lightning protection for IFRTs because it isn’t specifically mandated, assuming the risk has been engineered out.

Regarding IFRT’s, LEC has a different view. Although most lightning-related fires on petroleum storage tanks involve EFRT’s, IFRT’s have also been ignited by lightning and the downtime consequences remain significant.

Lightning can ignite an IFRT when a direct strike causes uneven current distribution. Due to the tank’s size, geometry, variable conductivity, grounding, and components (vents, shoes, hatches), current does not spread uniformly across the shell and roof, creating unpredictable voltage differences and induced currents.

Because peak current is delivered in fractions of a millisecond, the shell, floating roof, and components cannot equalize instantly, especially during multi-stroke flashes lasting over a second. As a result, different parts of the tank may remain at different potentials. If the voltage difference is high enough, an arc can form between the shell and floating roof. If sustained for a few milliseconds in the presence of flammable vapor, ignition can occur.

Although the lightning risk for IFRT’s is less than that for EFRT’s, the risk remains significant. Consequently, for maximum safety, shunts and bypass conductors should be required for both external and internal floating roof tanks.

When you compare the cost of installing lightning protection (on the order of several thousand dollars) to the potential cost of:

• Tank loss
• Environmental damage
• Extended downtime

…the value proposition becomes clear. Bottom line – do your stakeholders value marginal cost savings, or avoiding the far greater risk, and cost, of a lightning-induced IFRT ignition and the resulting downtime?

Global Dynamics Impacting StocExpo Attendance—and the Industry

This year’s event also reflected broader geopolitical realities. Attendance was lower as hostilities in the Middle East disrupted commercial air traffic, preventing many regular visitors from coming to the show. Despite the smaller crowd, we found an audience eager for knowledge and reconnected with valuable partners and customers.

The reduced presence of international participants, particularly from the Gulf region, highlighted an important fact: The tank storage industry is worldwide and sensitive to global disruption.

From crude flows to LNG exports, macro events are shaping not just markets, but industry engagement itself.

LEC’s Lightning Protection and Prevention Solutions – Leading Worldwide

LEC’s standout solution at StocExpo remains the Retractable Grounding Assembly® Gen 2 (RGA®), the industry benchmark for safely bonding floating roof storage tanks. By maintaining equal electrical potential between the tank roof and shell, the RGA protects both assets and stored product from the risks of static discharge and lightning strikes.

Since its introduction in 1999, more than 18,000 RGAs have been deployed worldwide, earning their reputation as the preferred global solution. The RGA Gen 2 is the original floating roof bonding solution, known for its high-quality design and construction, enabling lightning protection for the long-term.

Adoption across Europe underscores the RGA Gen 2’s performance and reliability, with over 18,000 units currently in service. European tank operators, widely recognized for their rigorous engineering standards and emphasis on proven technologies, continue to rely on the RGA Gen 2 to maintain safe, uninterrupted operations in even the most demanding environments.

The Bigger Picture: Innovation Still Leads

Stepping back, StocExpo 2026 reinforced a broader truth: innovation continues to define the trajectory of the oil and gas industry.

From robotics to fire suppression to evolving tank design, the pace of advancement is strong.

If there’s one unifying theme from StocExpo 2026, it’s this:

The industry is moving from reactive to proactive.

• From fixing failures to preventing them
• From manual processes to automation and robotics
• From isolated decisions to connected, data-driven strategies

But gaps remain, especially in how risk is understood and mitigated.

And in an environment where downtime equals dollars, closing those gaps isn’t optional, it’s a competitive advantage.
