Mechanical Integrity (MI) and Asset Integrity Management (AIM) programs have proven to be one of the most difficult process safety management (PSM) elements and plant activities to effectively develop and implement. Our professional engineering staff are mechanical and asset integrity experts who have the experience and capabilities to help clients overcome this challenge and create an effective MI/AIM program based on a thorough understanding of regulatory requirements and expectations.
We have helped hundreds of facilities develop and implement cost-effective and compliant integrity programs that meet OSHA PSM and EPA RMP regulations. We've also helped verify the integrity of process equipment.
We Wrote the Book
Our MI experts have provided process safety, reliability and risk assessment services to a wide variety of production and process industries since 1977. ABS Group has also contributed to many industry committees addressing MI issues including for the American Petroleum Institute (API), American Society of Mechanical Engineers (ASME), National Fire Protection Association (NFPA), Center for Chemical Process Safety (CCPS) and International Institute of Ammonia Refrigeration (IIAR). Our expertise in this subject matter was recognized when we were asked to author the book often referenced as the industry guidance for MI programs, Guidelines for Mechanical Integrity Systems (Wiley, 2006), for the American Institute of Chemical Engineers Center for Chemical Process Safety.
Services to Help Achieve and Maintain Integrity
Our solutions help you develop and implement cost-effective, technically sound and compliant MI programs through the following services:
In-Service Inspection Management
Owners of high-performance onshore, offshore and marine assets count on ABS Group to perform In-Service Inspection services to assess the condition, operation and efficiency of their critical equipment. The assets include everything from drillship and semisubmersible to floating LNG units, plants and refineries. The services can be provided during operation of shutdown, and upon completion we will issue a comprehensive report of all activity.
We can evaluate, inspect, maintain, design, analyze and improve various types of equipment, including electronic and mechanical equipment. Our qualified engineers and professionals will work with clients to eliminate or reduce downtime for fixed and rotating equipment, instrumentation and control systems.
Our product knowledge and insight enable us to develop optimal solutions, and we work closely and in strict confidence to understand our customer’s specific needs, concerns and requirements.
We also believe in the philosophy and practice of Concurrent Engineering. By early involvement with the project, and with our customer staff, we are able to avoid costly and unnecessary revisions.

Fitness For Service
Fitness for Service (FFS) is a well known and important concept in the oil and gas, chemical, petrochemical and other process industries. FFS is the ability to demonstrate the structural integrity of an in-service component even though it contains a flaw. This serves as a rational basis for defining flaw acceptance limits and allows engineers to distinguish between benign and dangerous flaws. Our professionals serve as contributing members of the API 579-1/ASME FFS-1 committee. We provide FFS for all damage mechanisms including:
- Fracture analysis
- Fatigue analysis
- Elevated temperature evaluation
- Failure evaluation
- Crack-like flaws
- General and localized corrosion
- Blisters and HIC/SOHIC damage
- Weld misalignment and shell distortions
- Fire damage
- Dents, bulges and laminations
Finite Element Analysis
Finite Element Analysis (FEA) is an approximation method of mathematically defining the geometry and the prescribed loading (boundary conditions) of a structure. We can provide a complete or partial 3D model of any structure or component. The extent of the modeling depends on the symmetrical boundary conditions.
- Structural static analysis - steady state and transient
- Static or dynamic analysis
- Modal analysis with harmonic response analysis
- Transient dynamic analysis
- Thermal analysis
- Spectrum analysis
- Buckling analysis
- Linear and non-linear analysis
- Fracture mechanics
- Composite analysis
- Fatigue analysis
Welding Engineering and Technical Support
Our welding engineers are recognized experts in adapting and developing welding procedures for new materials or to meet special project requirements. We offer a range of welding engineering and field support services, from working with the clients during design and fabrication to responding to an emergency in an operating facility.
We can review supplier procedures and production, welding practices for quality and cost effectiveness, develop new welding procedures, set up a jobsite test shop and welder training program and train project personnel to become welding inspectors and meet American Welding Society requirements. We also work with client suppliers to verify that specific welding procedures are followed during fabrication.
Our Certified Welding Inspectors can visit supplier shops to review welding procedures and confirm compliance with codes, standards and specifications. We work with suppliers to solve manufacturing problems and help maintain production schedules without compromising quality. We also help clients evaluate subcontractor manufacturing capabilities and quality control and quality assurance programs.
Root Cause Failure Analysis
Identifying and reducing risk at industrial facilities is a key management function. "How did it happen" is likely the first question asked by senior staff and managers after a workplace accident. Identifying the root cause of an incident so it does not happen again is a priority of our failure analysis professionals who work with clients to make major improvements in system design, employee safety and process safety, thus reducing the probability of repeated accidents.
Materials and Corrosion Engineering
We can provide assistance in performing a damage mechanism assessment and developing corrosion control documents with informational integrity operating windows. The process starts with an overview meeting with client operations, inspection and engineering staff to review the process operation shown on each process flow diagram (PFD).
The process overview will involve a detailed review of the PFD process streams in order to obtain the information needed to identify damage mechanisms and anticipated damage rates. Specifically, the ABS Group and client teams will identify operational and equipment history data/information such as operating conditions parameters, process stream constituents, fluid states, operating modes, failure histories, insulation conditions and humidity of process areas as applicable. Also, we will identify and generate a list of equipment records and data, such as piping specifications or equipment datasheets, needed to complete the damage mechanism assessment.
Based on these data, our engineers will work independently to identify the damage mechanisms and anticipated damage rates to provide:
- Set of PFDs with corrosion loops identified
- Set of corrosion control document tables with the initial assessment of the identified damage mechanisms and anticipated damage rates
- Integrity operating windows anticipated for each process stream
Resourceful people, skilled and dedicated to executing the project, are our keys to sound project management. We provide those people with appropriate project management systems to plan and forecast results. The interrelationship of our core activities and our geographical spread provide synergy and opportunities for the cross-fertilization of ideas and services.
The experience we have accumulated on large projects enables our project managers to combine the requirements of our clients with the logistical and technical support needed to accomplish each task from mobilization to reporting. As a consequence of our extensive international presence and experience, these efforts are seldom hindered by geographic location, local culture or commercial practices.
