Discrete Anodes Along the Tank Perimeter Not Satisfactory

The first retrofit cathodic protection system consisted of installing discreet anodes around the perimeter of the tank. While relatively easy to install, this method of retrofit installation often struggles to drive current to the full tank bottom. The results were not satisfactory so another method was needed.

Linear Anodes Installed Using Horizontal Directional Drilling

MATCOR had proposed an alternate approach, successfully being performed in the US but not tried previously in the Middle East. It involves the installation of multiple strings of linear anodes directly below the tank using horizontal directional drilling (HDD) technology. By drilling under the tank, it is possible to install anodes spanning the entire length of the tank. This method also allows for a testing device to measure the effectiveness of the cathodic protection system.

Vacuum excavation added to our wide range of cathodic protection construction services.

MATCOR continues to invest in new equipment to allow us to perform your projects in an efficient and safe manner with minimal downtime. MATCOR has seen an unprecedented investment in new equipment, having added multiple new drilling rigs to our fleet while rotating out our older models, purchased new water trucks, added MudPuppy mud cleaners and recyclers, and commissioned two new HDD rigs in the past three years.

But that is not all, MATCOR is very excited to roll out a new capability to our service line. We have purchased two state of the art Vacuum Excavators.

Vacuum excavation services now available.

These two new vacuum excavators are dual air and water units allowing MATCOR’s crew to operate efficiently in a wide range of environments. “Big Air” compressor capability provides 300 lbs. of cutting capability, enabling us to excavate in many areas without the need for water.

The excavated material is vacuumed up in a dry form with significantly less mess and environmental impact. This allows for the expeditious backfilling of the excavation with the same material that had been removed. It also eliminates the need to haul off any spoils or haul in fresh fill materials.

Our new excavators are dual capable units that also incorporate a hydro excavation capability. High pressure water is more aggressive and can cut through virtually any soil type including more compact, rocky and dense soil that may preclude the use of air. The hydro capability is also great for cleaning the pipeline once excavated to enable physical inspections and making test station or negative connections.

MATCOR is excited to be adding vacuum excavation to our in-house construction capabilities allowing us to provide a wide range of additional services to our customers.
