Our expansive network of offices across the country ensures our team is experienced and up to date on federal, state, and local codes to guarantee regulatory compliance and safety of the surrounding public. We also support your assets with a commitment to safety and reliability for all of your transmission and distribution projects.

Our services include a full spectrum of capabilities in gas transmission engineering, design, inspection, project management, and consulting. Our experience ranges from large market, expansion-driven, long haul projects to maintenance-focused integrity projects. Our experts also offer specific services in the areas of: Interconnects, Meter and Regulation Facility Design; In-Line Inspection (ILI) Pipeline Engineering; Horizontal Directional Drilling (HDD) Design; GeoHazard Analysis; Environmental and Permitting Coordination; and Land and Right Of Way (ROW) Support. Our team provides you with custom-built solutions in response to your specific needs, so you get exactly what you need–every time.


In-Line Inspection (ILI) pipeline engineering helps clients comply with regulations to provide complete records on pipeline location and integrity. The EN team is committed to design the best approach for each unique ILI project, including the smart tool (pig) launcher and receiver, as well as any required new or retrofitted pipeline facilities that are needed to allow the tool to move through and collect data with minimal impact to pipeline operation. Our engineers are highly capable to analyze this data to detect any pipeline integrity issues, such as dense corrosion pitting, dents, or reduced wall thickness.

Horizontal Directional Drilling (HDD) is an effective process to install pipelines, often long lengths, utilizing trenchless technology and with minimal impact to the feature being crossed. These features are typically sensitive in nature and cannot be disturbed by conventional open trench construction methods including roads, railroads, waterbodies (rivers, streams, wetlands), or other environmentally or culturally significant areas.

EN Engineering has completed the design of hundreds of HDD crossings, and we consider ourselves an industry leader in identification, planning, design, and support during installation of HDDs. Whether part of a larger overall pipeline installation or a stand-alone maintenance/replacement project, EN completes a preliminary front end assessment of all HDD crossings. We have developed a process that helps ensure the success of HDD crossings and minimizes stress on the pipeline.

EN manages geotechnical support services utilizing subcontracted third parties. These services include:

  • Subsurface Geotechnical Investigations and Reporting – investigations (primarily soil bores) are needed to assist in the design and construction of the pipeline and related facilities. These investigations assist in determining the character of subsurface materials, including the presence and depth of rock. The information gathered will aid in the design of any horizontal directionally drilled (HDD) and other crossing method, assist the pipeline contractor in determining the type of equipment needed for directional drilling, boring and general ditching and excavating activities, and assist in the design of pipeline and facility supports and foundations.
  • Hydrofracture Analysis – a hydrofracture analysis and related inadvertent return risk evaluation assists in establishing the maximum allowable drilling fluid pressure to be used during HDD operations in order to minimize the probability of hydrofracture or inadvertent fluid returns.
  • Geohazard Analysis – this study identifies potential hazards that could affect pipeline construction and facilities. Examples of these hazards include subsurface soil conditions, potential for landslides, and Karst features. These analyses provide clients with a better overall understanding of the terrain, geology, geotechnical conditions, and geological hazards discovered in their proposed pipeline corridor which could have an effect on the design, construction, and ongoing operation of the facilities.

EN’s experienced engineers manage environmental permitting coordination as a third-party service. Environmental permitting coordination may include any/all of the following: waters and wetland delineation, threatened and endangered species habitat assessment, regulated waters permitting, cultural resources survey, a history or architecture investigation, and stormwater pollution protection plans (or erosion control plans). Permitting/filings may be with any of the following: Federal Energy Regulatory Commission (FERC), US Fish and Wildlife Service (USFWS), Army Corps of Engineers (ACOE), U.S. Environmental Protection Agency (EPA), and state and local agencies.

EN’s expert engineers manage land acquisition and right-of-way (ROW) support as a third-party service. This service includes review of GIS parcel information, development of a property owner list, deed and title research, property exhibits (non-certified), land valuation, survey notifications/permissions, land acquisition (or ROW procurement), review encroachments of 3rd party assets (ex. foreign pipelines, water mains, etc.), ROW support during and after construction, condemnation (or eminent domain, if required), legal descriptions of easement and workspace, and recording plats with the county.

Document Digitization

Most companies have large volumes of paper documents that contain information required for critical operational processes. Paper documents have limited access and introduce inefficiency and errors into the organization’s work processes. EN’s data solutions experts provide our clients with digitization services. We support digitization and integration of historic and current paper documents into a client’s data system. First, we conduct a detailed inventory of the available records and estimate the cost of digitizing these documents and the impact on our clients’ operations. When the cost of digitizing the documents is justified by the value gained, we develop a plan to digitize the relevant documents. Depending upon the requirements, digitizing the documents can be done by scanning them into a digital format, tagging them with relevant information, and linking them to the appropriate assets. If the requirements demand a higher level of integration, the source documents can be manually reentered as digital data. Both processes allow our clients to query, search, run reports, or otherwise use the data to better support their operations.

Data Cleansing and Verification

Reliable and accurate data is the foundation of an effective data system. Our expert consultants have years of experience working within data systems to cleanse them of errors, duplication, or other discrepancies. When engaging in these initiatives, we identify and quantify the errors and evaluate the potential cause and the severity of the error. After locating the gaps in quality, we evaluate the costs and impact of various correction techniques from low cost/low accuracy automated algorithms to high cost/high accuracy manual fixes. The desired accuracy and cost of the corrections drive the development of an overall data enhancement plan prioritizing data cleansing with respect to the severity of the data. EN then supports the execution of the data enhancement programs by managing activities, performing corrections, and reviewing the enhanced data.

Data Maintenance

One of the key requirements to obtaining high value from modern decision support and analytics applications is high quality data. While starting with high quality data is one factor in this value chain, maintaining data quality through a system is equally important.

We can also help with test station configurations and design, electrical isolation, and station facilities. We have extensive experience with multiple industries including oil, gas, water, wastewater, and electrical utilities. All designs are performed in accordance with NACE, AWWA, and other guidelines as appropriate.

AC Interference and Stray Current Analysis

With an ever-more crowded world, AC interference situations are increasing in number and intensity. From new construction to existing assets, EN can accurately analyze the situation at hand. Our team of experts are careful to examine all possible threats and risks before recommending a course of action. We are one of the few firms to perform in-house modeling, with specially trained staff to match any scenario.

DC Interference and Stray Current Analysis

DC interference and stray current can result in vexing situations for the operator. EN’s corrosion group helps our clients to not only identify where the interference is coming from but help diagnose the situation at hand. Whether its static, dynamic, or a combination of the two, we are prepared to help. Our team has experience with transit, water, petroleum, and electrical power systems. We are uniquely positioned to provide expert recommendations on how to best mitigate the interference to protect your asset.

Oversight & Commissioning

The most critical stage of any asset’s life is construction. EN provides third-party inspection or oversight services to ensure that construction crews are installing the system as designed. We’re also there to provide sound engineering solutions to any situation that may arise. After construction, our team provides commissioning services to ensure proper installation and performance of the corrosion prevention systems. Other services include post-construction coating surveys, native surveys, rectifier tuning, isolation testing, and baseline reads.


When a client has problems with their cathodic protection system, and they’ve sought solutions that has not yielded answers, EN can help. We provide experienced staff with a high degree of technical capabilities to help troubleshoot the situation. With our expertise, we can diagnose the situation at hand and provide custom-tailored remedies. This may require specific field equipment, specialized surveys, coordination with third parties, or the use of software modeling.

Internal Corrosion

By its nature, internal corrosion is not always the easiest situation to monitor or address. EN helps operators perform routine assessments or address unforeseen situations. Our cross-functional teams from Integrity and Metallurgy assist our Corrosion group in providing the best solutions and recommendations for any issue. Be it coupon testing, liquid sampling, in-line inspections, or even depth of cover surveys, we are here to help.

Wellhead Piping Analysis

EN’s corrosion experts can help storage fields assess the cathodic protection of their wells or gathering system with field surveys such as ElogI, Cathodic Protection Profile (CPP), interference, or isolation testing. These can be done as stand-alone surveys or performed with other down hole surveys and activities in support of Storage Integrity Management Plans (SIMP). Whether for a single well or the entire field, EN’s expert team helps owners and operators ensure the asset’s integrity and maintain its working life.

Renewable Energy

For renewable energy, specifically solar and wind (both onshore and offshore), we perform assessments to ensure structures will meet their design life. This assessment considers the environmental conditions, structural design, and local soil conditions. In some instances, coatings and cathodic protection systems may be designed to achieve the desired operational life. We also provide interference studies from these fields onto third party assets, studies on the reverse (third party assets onto the field), and studies on third-party crossings. For permit level activities, we can assist by performing lifecycle calculations and corrosion rate analysis.

Surveys and Inspections

EN has a qualified and experienced team to perform the field surveys you made need. These include ACVG, DCVG, CIS, ACCA, depth of cover, direct assessments, interference surveys, HDD coating evaluations, native and interrupted surveys, soil resistivity, or even custom troubleshooting. We can assist in code compliance readings including annual surveys, rectifier readings, critical bond assessments, post-construction coating assessments, and atmospheric inspections. Corrosion specialists are also part of a multi-disciplinary team at EN that performs an external corrosion direct assessment (ECDA) and internal corrosion direct assessment (ICDA): an entire program including a pre-assessment, coating and/or corrosion indirect surveys, direct assessment, data analyses and presentations, and reporting.

Failure Analysis

Pipeline components fail due to unanticipated loading conditions or reduction of material strength from mechanical damage, corrosion, or other environmental factors. Determining the root cause of failure requires understanding of the material properties, microstructure, manufacturing processes, operating conditions and original function of the component. EN Engineering failure analysts are degreed metallurgical and mechanical engineers with decades of pipeline industry experience in determining the cause of failures.  Through metallurgical investigations using optical and scanning electron microscopy, and stress analysis using finite element analysis, EN can determine the cause and suggest corrective actions to guard against similar failures in the future.

Welding Procedure Development and Qualification

EN Engineering provides welding procedure development and qualification to support pipeline installation, maintenance, and repair. Our metallurgical team has assisted pipeline companies in developing new construction and in-service Welding Procedure Specifications (WPSs), Procedure Qualification Reports (PQRs), and welder qualifications. Our services include field qualification and classroom training for WPSs, welder qualification and inspection to ensure safe welds in compliance with regulatory requirements and practices.

Fitness-for-Service/Engineering Critical Assessment (ECA)

A fitness-for-service evaluation determines the capability of an engineering component to continue functioning with a known defect – metal loss, corrosion, crack-like flaws, laminations, etc. When crack-like defects are involved and fracture mechanics methods are employed, the fitness-for-service evaluation is commonly called an engineering critical assessment (ECA). In the petrochemical, refinery and pipeline industries, the standard API 579-1/ASME FFS-1 Fitness-for-Service is widely used and addresses repair or replace decisions for many commonly occurring defect types. EN Engineering has performed many API 579 fitness-for-service evaluations and ECAs on pipelines and pressure vessels with corrosion, mechanical damage, and cracks. These evaluations provided repair/replace decisions and inspection scheduling intervals for components determined suitable for continued operation. 

Material Selection & Verification

Procurement of pipeline and facility components to meet design requirements depends upon accurate descriptions in bills-of-material and, upon receipt, verification of proper material to meet the order. Recently enacted federal pipeline regulations require that all components have traceable, verifiable, and complete (TVC) records to be maintained for the life of the pipeline. EN’s material specialists regularly review the material test reports (MTRs) of purchased engineered components to ensure conformance to industrial standard (ASTM, ASME, API) norms. Integration through EN data management systems can ensure secure and readily accessible material documentation for efficient operation of industrial facilities.

Pipe Mill Audits and Qualifications

At EN, our metallurgy group often supports clients to audit pipe mills before adding them as an approved supplier. Within this service, our audit process includes visiting the pipe mill to witness rolling pipe, checking instrumentation, ensuring qualifications are up-to-date, and observing quality processes. We typically either perform this work prior to the client working with a particular pipe mill or when they’ve already purchased pipe for a specific project. In addition to the audit process, our team can also support clients in oversight during the first days of production to ensure the process runs smoothly.

Pipe and Fitting Specifications

EN’s metallurgical group serve on ASME and API standards committees to participate in the development of pipeline component standards. We have a thorough understanding of industry and regulatory standards and their applications in pipeline design, construction, and operation. EN’s specialists have produced pipe, fitting and valve specifications for pipeline and industrial facility clients who require more stringent requirements for their operating environments. The safe installation and construction of pipe and fittings benefits from front-end knowledge of metallurgy, material selection, welding procedure development, and best installation practices.
