Most CP retrofit projects happen on tanks that are already in service, which raises a different set of questions:

How do you install a system under a tank that's already there, and how do you verify it's actually working once it is?

This technical article on retrofit CP covers both.

➡️ On the installation side, linear anodes placed beneath the tank using horizontal directional drilling (HDD) avoid the need to take a tank out of service or disturb the foundation.

➡️ On the verification side, fixed reference electrodes give you a way to confirm CP performance is consistent across the entire tank bottom, not just at a few spot checks.
If you're managing an aging AST fleet and cathodic protection wasn't part of the original build, this is a good place to start.

Cathodic protection isn't the only tool for managing corrosion risk on tank bottoms.

V***r Corrosion Inhibitors (VCIs) can work alongside CP, particularly on aging or challenging tank applications where CP alone may not tell the whole story.

The best time to plan cathodic protection for a new aboveground storage tank is during the design process.

Retrofitting CP for an existing tank bottom is possible, but it’s typically more complex and costly than planning for it upfront. You must determine foundation layout, anode placement, and how you'll test and monitor the system before the tank goes into service, not after.

This technical paper walks through that planning process:

➡️ How foundation design affects anode placement
➡️ What to consider for long-term monitoring
➡️ How to set a new AST up for decades of reliable corrosion protection from day one.

If you're in the early stages of a new tank project, this is worth a read before the foundation goes in.

Tight clearance under a tank doesn't have to mean compromised cathodic protection.

The patented SPL-SandAnode™ is engineered for exactly this challenge, with sand backfill that lets the anode install directly beneath a tank, even with less than a foot of clearance.

When conventional anode systems won't fit, this is the workaround that doesn't cut corners.

What would a 23% smaller deep anode system budget do for your next project?

That's the real number from two side-by-side competitive bids — a Durammo® system vs. a conventional deep anode design, same project scope, same bidding situation.

Where the savings come from:

🔺 Lower installation cost — factory-assembled systems install in minutes vs. hours of field assembly for discrete anode strings

🔺 Longer design life and more stable performance, which lowers total cost of ownership, not just upfront price

🔺 Savings that widen on multi-site projects, where eliminating per-install field assembly time adds up to full project days saved

If your budget conversations are still comparing anode systems on unit price alone, this is worth a second look.

Anode material choice changes the entire design for a deep well groundbed.

MMO anodes are dimensionally stable. They act as a catalyst rather than a sacrificial material — consuming at a rate of milligrams per amp-year.

HSCI and graphite anodes consume at pounds per amp-year. That difference alone drives anode sizing, spacing, and expected service life in a fundamentally different direction.

This technical paper walks through the design variables that matter most:

➡️ Borehole diameter and current output requirements
➡️ Coke breeze backfill behavior
➡️ How anode geometry (continuous wire vs. discrete rigid anodes) changes installation tolerances and long-term performance

If you're in the early design phase of a deep anode groundbed — or reevaluating an existing one — this is a solid reference for getting the fundamentals right before you spec hardware.

Nearly 10,000 Durammo® Deep Anode Systems. Over 200 million cumulative operating hours. 30+ years in the field.

What makes it different from a conventional deep anode groundbed:

✅ Factory-assembled, not field-built
✅ Continuous current discharge
✅ No resistor junction box

If you need to spec a deep anode groundbed and you’re weighing continuous wire vs. discrete anode strings, this is worth a look.
