Inspecting and Managing Aging Infrastructure

As facilities get older, more repairs and replacements are required to keep a plant and its applications operational. Inspection teams are called in to make recommendations on the best steps to move forward, and that is where William Wilson found his niche.

Hose + Coupling World had the opportunity to sit down with Wilson to discuss the different types of inspections he handles, the new technologies available, and the importance of networking at national events.

William Wilson has always felt at home in the field of inspections. Just over a decade ago, he started working for Orbital Engineering Inc., and has held a verity of positions within the company since. His first position involved executing structural inspections for facilities by evaluating a plant’s assets, its cranes, and walking working surfaces. Over time, Wilson worked his way up to Program Coordinator which entailed scheduling inspections and helping to develop the means and methods for each inspection.

“We needed to determine how we were going to inspect each structure, as well as the safety aspects. This involved asking questions like, ‘What parts do we need to lock out for a safe inspection?’, ‘What areas do we need to clear so that we can access the asset with an aerial lift?’, and ‘Do we need a crane and man-basket to properly reach the area?’ Essentially, all of these questions would determine how we would inspect these structures safely and efficiently.”

Wilson was then promoted to Asset Integrity Department Manager for the St. Louis, Missouri office and only two years later, he was promoted to Regional Manager. He oversaw the operations at the company’s facilities in Hammond, Indiana; Philadelphia, Pennsylvania; St. Louis, Missouri; and Houston, Texas, where he continues to fulfill his role as Regional Manager.

Never an Ordinary Day

There are many tasks that Wilson is responsible for based on his management position. One of these tasks includes supervising all the workers that inspect structures within customers’ metals, bulk handling, refining, petrochemical, chemical, and power generation facilities “I oversee what is called ‘boots-on-the-ground’ inspections. If it is any type of steel structure, you can bet that we are inspecting it,” Wilson said. After their inspections are complete, the company will also provide repair recommendations and will prioritize the repairs for the maintenance workers.

Although Wilson does not perform most of the plant inspections personally, he instead coordinates the field efforts and ensures the company’s deliverables are submitted to all customers on time. With such a wide range of responsibilities, Wilson’s weeks often vary, with some spent in the office and others spent travelling for meetings.

While he is responsible for the coordination aspect of the inspections, he is also dedicated to the company’s sales efforts. The teams Wilson oversees includes more than just degreed engineers. “I work with a fully multidisciplinary engineering team. This includes electrical engineers, civil structure engineers, mechanical engineers, designers, and inspectors with a technical background,” Wilson stated. “Our technical inspectors are taught by our engineers and go through a very robust training program.”

A large part of Wilson’s job is to make sure all of the inspectors understand how to recognize different structural components. The inspectors need to have the ability to identify and know where problems are going to occur in a plant, they need to know whether or not the environment is corrosive or caustic, and know how to document all of this information in a formalized report. The report is used to provide information to engineers so that, if there is a need to develop a retrofit design repair for a specified structure, all the information is readily available.

New Inspections and Challenges

Each inspection that is performed by Wilson’s team is different, and that is what he enjoys most about his job. “One day I am in a plant performing inspections with my hard hat on, the next day I am dressed up and sitting down at sales meetings, and the next I am going to lunch and learns,” he explained. “I really enjoy meeting new people and networking with potential new clients.”

When asked about what challenges him the most, Wilson admits, “it is more of a frustration than a challenge.” The inability to give his clients an answer or a solution right away is something that prevents him from completing a task. “I feel as though I let them down, but then I go and look deeper into the problem to find a solution.” If Wilson and his team do not have a solution in-house, he reaches out to other SMEs at the other five Orbital offices to find the solution.

A Variety of Projects

Wilson describes his team as being “well-diversified”. The team will work in any type of facility including metal production, petrochemical, oil and gas refining, mining, railroads, and power generation. The majority of assigned tasks consist of brownfield projects, which include inspecting already standing structures and aging infrastructure. Orbital Engineering has developed its own proprietary software program to complete more condition-based risk assessments on structures, which is a direct result of over fifty years of experience performing structural inspections, engineering and repairs all while lacking a standard set of industry codes to follow. This program helps both Orbital’s clients and its inspectors.

The inspection team also has approximately 30 standard repair procedures developed in-house. Among these procedures are how to repair a cracked weld, how to repair a hole in a beam, how to repair concrete and fireproofing applications, and how to replace bolts. These standard procedures are documented and included in the inspection reports to enable a seamless hand-off for the repairs to a subcontractor who can properly complete the task.

The inspections also determine whether or not repairing or replacing components or applications will be more cost-efficient for the plant. “It is all about finding the best solution. For example, if we are inspecting a unit made of carbon steel, we may say it needs to be galvanized, or the plant requires a certain sensor type and coating to prevent further deterioration. If it is a hole in a beam, we can determine that it is actually more cost-effective to put a patch plate in the beam rather than replacing the whole thing. Preventative maintenance is key,” Wilson stressed.

There are a few procedures that Wilson suggests can help in preventative maintenance. “Clean off your structures on a routine basis,” he emphasized. A regular occurrence Wilson has noticed throughout the past few years, is a reduced budget for coatings.

Hoses and Valves

Wilson and his team execute plenty of mechanically-based inspections. “We do a lot of American Petroleum Institute (API) inspections, including 510, 570, and 653 among others,” he says. When it comes to specific applications such as valves or hoses, Wilson’s team is involved with spill prevention, control, and countermeasure (SPCC), which is typically applied across all industries. When a valve leaks, Wilson’s team will identify where the leak is coming from, recommend repairs, and support the repair contractors through the process.

Supporting companies through repairs includes everything from the initial inspection, to finding and hiring a contractor to do the repair, all the way to the completion of the job. “We fill the work order, then validate and verify that the repair has been completed. Sometimes it is a repair situation, and sometimes it is a replace situation, and we are there through it all.”

When it comes to hose inspections, Wilson typically works in desert areas where dry rotting is a frequent concern. Sandstorms and dry air negatively affect the hoses. When the application are placed in these hostile environments, the hose’s material of construction can begin to blister and peel as a result. When this deterioration is experienced, the product must be replaced immediately.

Aging Infrastructures

As aging infrastructures are a growing concern, Wilson is preparing his team for the inspections he sees coming down the line. “Older facilities are going to become a problem—that is a fact. It has already started,” Wilson stated. Plants that are located along the Gulf of Mexico are also being attacked by the environment, which includes salt from the Gulf’s waters or hurricanes. Any inspections and repair recommendations of older facilities need to comply or at least be reconciled with the new industry codes, and any corrosive material handling needs to be treated with more care.

The goal is to develop more preventative maintenance approaches for these facilities during the inspections. However, Wilson’s team finds many of the plants are reluctant to use their own budgets. Wilson intends to help “knock out” the higher priority deficiencies in the plants that are easily identified and create a plan for the maintenance teams to carry out. “If we remove the big problems, we can increase the efficiencies in the plant and gradually address everything else that needs to be done.”


A new technology that Wilson has seen in the field of corrosion prevention is the pulsed eddy current non-destructive testing (NDT). It is an advanced electromagnetic inspection technology used to detect flaws in ferrous materials typically hidden under layers of coating, fireproofing, or insulation. For Wilson’s team, the tool is predominantly used to detect imperfections in fireproofing layers. If there are voids or cracks in the fireproofing layers, water and other moisture can start attacking the structural steel underneath, which will lead to accelerated corrosion and other forms of deterioration. With the pulsed eddy current, the inspection can occur without removing the layers of fireproofing—which would then have to be replaced after the inspection was complete. This type of NDT simplifies the process, which is helpful to Wilson’s team and the people at the facilities.

A Lifetime of Learning

As the plants age, so too do the operators that handle the assets. “You should want to leave the plant in better shape than when you found it,” said Wilson. This thought drives him and his team as he goes out for inspections. “We see an aging workforce, and when we come across those who are close to retiring still working in a plant, I just want to put them in the same mindset. Why should a person leave and take all knowledge and experience with them, without sharing with other engineering, operations, or maintenance personnel? If we are able to share that information, the plant and other engineers will be much better off for the future.”

National Conferences

In order to pass along knowledge for future success, Wilson recommends that the new generation of industry engineers and operators attend and prepare presentations for as many conferences as possible, as it will give them the chance to learn from industry leaders. “It is always a good thing to go and see who attends the exhibitions and participates in the conferences. It is a great way to scout out new potential customers or suppliers, and then you can go back to your company and tell them about what you learned,” Wilson explained.

Wilson also emphasizes the importance of these events for networking opportunities. “Meeting and getting to know people who are the subject-matter experts is a great opportunity. You will never go wrong sitting in on a conference session and actively participating in conversations with other industry professionals.” Wilson often considers social media networking as superficial, because it is never the same as meeting someone face-to-face, and building a relationship is best done in person. “That is why a conference like Hose + Coupling World is so successful for inspection teams. We can meet with the people attending and learn how to better serve the industry.”
