Third Party Audits and Front End Engineering Design (FEED) Reviews

Consulting Valve Design Review

Design reviews through third-party audits and front end engineering design (FEED) studies are essential quality control activities to ensure facilities and processes are designed according to engineering best practices.

Design reviews are an imperative part of facility construction and maintenance. MISTRAS offers a variety of design reviews, including third-party audits and front end engineering design (FEED) studies, to help clients determine key details about their projects, ranging from detecting design flaws to establishing project timelines. Clients in the oil & gas, petrochemical, and other process industries benefit from having licensed, engineering experts help to ensure that their assets and facilities are operating at their optimal capacity. 

Third-Party Audits

Third-party audits act as quality control for systems, components, and equipment throughout the engineering design process. These audits follow customer-specific requirements and are administered independently to provide an accurate report. Third-party audits occur before systems are in place to prevent major discrepancies in working operating units.

Quality control is typically referred to as the adherence of a manufactured product to required specifications. However, third-party audits are another equally important type of quality assurance that deals with performing audits not on products, but on engineering design.

Cost Savings and True Value

Operational challenges faced by owner companies, contractors, and equipment manufacturers have resulted in lower levels of human resources and experience than in the past. These developments require new approaches and solutions to maintain proper performance and quality control.

MISTRAS' design audits provide benefits in two ways:

  • Cost and time associated with our performance of an engineering design audit are minimal when compared with the potential adverse impact undiscovered discrepancies can have on operating units.
  • Fees and expenses for performing engineering design audits offer considerable savings when compared to the direct and indirect costs of maintaining an effective in-house engineering quality control organization.
Third-Party Audit Scope

MISTRAS Engineering Services delivers reviews free of bias for or against any product or technology. Where design alternatives are indicated, we make recommendations based on practicability and technical excellence.

Based on the needs of an engineering situation, a design audit may focus on a small number of critical equipment items, or applied on a wider basis to the design for an entire project. In the latter case, carefully-developed screening procedures are used to check contractor and vendor performance on a sampling basis. If discrepancies are found in a particular area, increased attention is directed, and corrective actions are recommended as appropriate.

We've developed plans and executed engineering design audits for major capital projects worldwide in Europe, the Middle East, Asia, and North America.

Front End Engineering Design (FEED) Studies

Front End Engineering Design (FEED) studies help refineries screen processing options and select a lead project case for producing gasoline and fuels. This approach controls expenses, evaluates project execution strategies, assesses risk, tests design basis, and develops staffing plans for all phases of the project. MISTRAS consultants perform FEED studies after determining the feasibility of constructing a project's initial conceptual design.

Front-end engineering studies and technology licensing support are important parts of our engineering consulting practice. The following information relates to our capabilities with particular reference to the manufacture of ultra-low-sulfur gasoline and diesel fuels.

Objective: The objective of a front-end engineering study is to help the client screen various processing options for its refinery and to select a lead project case for further engineering of facilities to make a particular product - in this case, ultra-low-sulfur gasoline and diesel fuels.

Priority: The emphasis is on cost-effective re-use of existing equipment and on the integration of any required new equipment into the existing facility. An assessment of technology options, including in-house and third-party technologies, is made to determine the most favorable option. Three types of information are developed jointly with the client for each selected processing option:

  • Product yields and qualities
  • Investment and operating costs
  • Screening economics

Study Methodology: Our assigned engineering specialists (both low-sulfur technology and project planning specialists) hold a kick-off meeting with the client's refinery personnel. The purpose of this important meeting is to assure mutual understanding of the current operation, agree on the various process options to be screened, and develop a work plan with an anticipated study schedule.

The study builds on existing information such as past planning studies, equipment drawings, existing unit performance data, hydrogen balances, and additional information developed by us or provided by licensors of ultra-low sulfur fuels technology.

Study Results: Upon completion of the study, the team meets with refinery management to present the results, including a recommended case and alternative cases for further engineering steps in the project. Final documentation of the study is submitted shortly thereafter, and typically includes the following items:

  • Screening economics
  • Product yields and qualities
  • Investment and operating costs
  • Discussion of the assessment of technology options
  • Critical interactions with the existing refinery facilities
  • Optimization opportunities for the lead case

Study Cost: We work to provide a study scope that will deliver maximum results within the client's budget.
