The resulting data is incorporated back into the risk rankings, which is typically performed more than once a year for our clients.

Continual Evaluation

EN’s highly trained staff has extensive experience developing and implementing Continual Evaluation processes used to evaluate results and make process improvements. The process is cyclical in nature and begins with an initial assessment. EN can help operators analyze if the processes in place are effective and define an interval appropriate between assessments as they schedule and plan work. This helps operators practice the cycle of routine monitoring and evaluation, followed by continuous improvement within a specified timeframe that meets regulatory requirements. Our team also aids operators in cost saving considerations by developing a holistic plan based on results.

Records Validation

EN’s team is experts in record validation, a comprehensive service that goes beyond what code requires when retrieving data to perform calculations for Maximum Allowable Operating Pressure (MAOP). We expand on the data collection to encompass what is required by code, as well as other available data (sometimes 50 or more additional attributes) during that process that is extremely useful and would be cost-prohibitive to go back later and collect. This additional information is then integrated into clients’ GIS system and is extremely useful later when planning any work on the pipeline, such as corrosion.

MAOP Reconfirmation

EN Engineering provides support for the six methods operators may utilize for pipeline(s) subject to MAOP Reconfirmation. These essential services include:

• Performing a pressure test, and if the records are not traceable, verifiable, and complete (TVC), cut-outs will be required at the test manifold for material verification,
• Pressure reduction,
• Pressure reduction for segments with small PIR,
• Replacement, with CP system updates and post-construction surveys,
• Engineering critical assessment (ECA), a detailed process per §192.632,
• Or, alternative technology.

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.
