CADE’s engineering analysis services comprise those engineering, simulation and consulting multidisciplinary services that are aimed to assess critical plant equipment, high temperature piping, pressure vessels and structures when performance is not the expected, failure has occurred or mechanical integrity and remaining life must be evaluated.
Fitness-for-Service (FFS) Assessment is a quantitative engineering evaluation to determine if an in-service equipment is safe and reliable to operate at specific conditions along a defined time. FFS must be consider as a critic stage of any Mechanical Integrity Program.
Some of cases in which FFS is a valuable engineering tool:
Obviously, main benefits of FFS are to grant safe and reliable operation, but also allowing reductions in downtime by eliminating unnecessary repairs, giving extra time to plan shutdown and furthermore reduces eventual costs.
Along years CADE has applied successfully, and deepen his knowledge in FFS methodology, extending his application not only to in-service equipment, but also to post-fabrication acceptability, pre-commissioning validation or failure investigation support.
We offer a multidisciplinary approach, mechanical and process oriented, counting, in addition, on strategic partners or ad-hoc collaborations with reputed inspection, verification, testing and certification firms to provide full integrity evaluation including non-destructive testing (NDT), materials testing, field services, or notified body reports/services.
Plant equipment, high responsibility piping or critic components not meeting their intended design life, or accidents and failures often result from factors including:
CADE delivers comprehensive assessment and investigation of failures counting on a multidisciplinary engineering approach, as powerful tool to determine what have actually occurred when an in-service failure arise.
Usually, a combination of factors is responsible of failure. Determination of the influence of identified potential factors and how these factors have been combined to lead into a failure is the key to demonstrate, through a physical and /or a simulation model characterization, its source.
Once hypothesis of failure is demonstrated, corrective measures are proposed and validated by means of mathematic simulation models, including FFS evaluations, laboratory tests or on-field verifications. Subsequent modifications or upgrading measures can be engineered and designed by CADE.
CADE engineers collaborate with plant operators, process licensors and engineering firms to solve some of the industry’s toughest and critic equipment reliability, performance and plant availability challenges.
Operating and historical data analyses identify opportunities or foresee future issues. Modeling and technology-aided tools pinpoint problems. Lifecycle cost calculations provide solutions, technical recommendations and economic justifications.
Performance assessment includes evaluations of thermal, hydraulic and mechanical design, accumulated damaged through historic operation and impact of upset conditions on equipment and systems. CADE’s performance assessment have proven especially valuable in plants where process parameters have changed or where systems degradation has occurred.
