Large AC Interference Mitigation Project in Southern Wyoming

MATCOR expedited manufacture and installation for this “late start” AC interference mitigation project requiring over 73,000 feet of gradient control wire.

Installation Challenges

The construction window in the High Plains Region encompassing southeastern Wyoming is a relatively short one as the winter months can be quite inhospitable to construction activities.

As such, the disruption caused this year by COVID-19 resulted in numerous projects’ starts being delayed as companies dealt with the pandemic, leaving installation contractors with less time to complete critical installations.

MATCOR was recently involved in one of these late start projects. A new construction AC transmission line was built, encroaching on the right of way of an existing pipeline in Southern Wyoming. AC transmission was scheduled to begin in early November of 2020.

AC Modeling & Mitigation Design

The pipeline operators had commissioned an AC modeling study and mitigation design which was not finalized until early August.

MATCOR was hired on August 5th, by the pipeline owner, to supply and install the mitigation design with a completion date of October 1st.

The mitigation design called for the installation of:

  • Approximately 73,500 linear feet of MATCOR’s Mitigator® Engineered AC Mitigation System gradient control wire
  • Three deep well grounding systems
  • AC coupon test stations
  • Satellite RMUs (remote monitoring units)
  • Solid state decouplers

MATCOR did not hesitate to commit to this aggressive installation schedule that required materials to be manufactured and procured on an expedited basis.

MATCOR is the OEM for the AC Interference Mitigation System

As the original manufacturer of the Mitigator, MATCOR was able to immediately ship 10,000 feet from stock inventory. The balance of the material was immediately moved to the front of our production schedule. Within a few days of receiving the order, MATCOR had mobilized to the site and was making preparations to kick off the installation.

MATCOR performed the Mitigator installation using a cable plow with a dozer providing a pre-rip. MATCOR also deployed a new hydro-vac truck to perform pot holing for line locating and test station installations.

A MATCOR drilling rig and crew performed the deep grounding drilling.

Completed Ahead of Schedule

The entire AC installation was completed and commissioned one day ahead of the scheduled completion date without incident and to the pipeline owner’s satisfaction.

This project highlighted all of MATCOR’s core competencies:

  • Manufacturing of materials
  • Broad construction capabilities
  • Professional project management
  • Field technical expertise

When you need to get it done and the clock is ticking – MATCOR performs.

In response to the surging hyperinflation of global iridium prices, MATCOR is instituting, effective February 1st, a temporary surcharge on the price of all our MMO anode products.

The surcharge is necessary to offset the significant increases in MMO coated materials, specifically iridium.

The surcharge varies depending on the product and its MMO cost component and will be shown as a separate line item in our material proposals.

Price Quotes for MMO Anodes

Additionally, MATCOR is reducing our quote validity dates to two weeks and stipulating that the price validity is based on the price of Iridium remaining below 4500/oz. Should the price of Iridium exceed 4500/oz, MATCOR will review and confirm validity of the pricing at time of order placement.

We regret that these measures must be taken, but these are extraordinary times. MATCOR is committed to working with you to minimize the cost impact of the global iridium price surge.

This includes reviewing your project needs and evaluating alternate anode solutions.

Global Iridium Pricing Crisis – FAQ

Iridium Price Increase cathodic protection

Surging Iridium prices have shocked the cathodic protection industry. We have put together the following FAQs to explain what iridium is and how it is used in cathodic protection materials.

What is Iridium?

Iridium is a rare earth metal that is, as the name implies, quite rare. It is considered part of the Platinum Group of metals as it is found as a trace element in the extraction of platinum. It is the second densest, and the most highly corrosion-resistant of all metals.

How is iridium used in cathodic protection?

It is the primary active element for all Mixed Metal Oxide (MMO) anode coatings used in oxygenated environments which include coke, soil, mud, fresh water – basically anything but seawater which is a chlorinated environment.

How expensive is iridium?

Up until a few weeks ago, Iridium prices were generally stable throughout 2020 in the range of $1500 to $1700 per ounce. In mid-December the price of Iridium skyrocketed over 200% in the space of a few short weeks. This hyperinflation in the cost of Iridium has caught the CP industry by surprise, and MMO anode suppliers are being forced to dramatically raise prices because of the significant additional costs of Iridium Oxide used as the active catalytic element.iridium price increase january 2021

Why is the price of iridium skyrocketing?

There are a couple of factors that have created this pricing crisis. First, most of the world’s Iridium comes from a few Platinum mines in South Africa, and with the global pandemic having recently hit South Africa very hard with a new and more virulent strain of Covid-19, the mining output has diminished significantly. We hope this is a short-term supply issue. The second factor has to do with the European Union announcing a major investment in Hydrogen as a green fuel for electrical generation. A new membrane technology (PEM) uses iridium as a catalyst to generate hydrogen. The announcement led to several speculators buying up Iridium supplies and driving the price up.

What happens next and how long will this last?

It is impossible to predict how high the price of Iridium will rise before reaching a peak, how long the pricing remains at these elevated levels, and what the stable price in the future might be for Iridium. What is certain is that the supply of Iridium will adjust as the mines in South Africa go back to production and as the elevated price leads to more supply being developed to meet the demand. Historically the supply of Iridium has always been available to meet the demand and when that equilibrium is restored, we can expect the price to drop and stabilize.

What is MATCOR doing to address this issue?

MATCOR is applying a surcharge on all MMO Anode products effective February 1st. We will continue to monitor the MMO situation and work with our suppliers to maintain our supplies and contain our costs as best we can. We hope that this is a temporary situation that will resolve itself in the next several months.

Are there alternatives for cathodic protection that do not utilize iridium?

We still believe that MMO anodes remain the best anode material when considering the outstanding track record of this anode, its dimensionally stable properties, and its long service life. However, MATCOR can also supply conventional anodes including high silicon cast iron and graphite anodes. We are also evaluating Platinum anodes which were the original dimensionally stable catalytic anode before the advent of MMO, although platinum has its limitations and is simply not as robust an anode material.
