Fitness for service (ffs) & Finite Element Analysis (fea)

Zachry Integrity’s expertise in Fitness-For-Service (FFS) assessments is supported by a team knowledgeable in FFS techniques to determine whether damaged equipment can continue to be safely used. We have performed evaluations for reactors, vessels, tanks, truck frames, and pipelines using API 579/ASME FFS-1 methodology. Our analysis investigates the underlying damage mechanisms leading to a material’s fatigue and fracture. Zachry’s team is up-to-date and involved with FFS research, such as our submission to API/ASME to support changes to a Level 2 assessment methodology for thermal hot spots. With experience ranging from simpler Level 1 to rigorous Level 3, Brighton’s ability to apply the right approach results in cost and time savings to clients.

Zachry’s engineers combine expertise and extensive industry knowledge along with skills in a variety of Finite Element Analysis (FEA) platforms to quickly solve real world problems pertaining to in-service failures. We apply sound engineering principles and are prepared to assist urgent investigations by offering expert opinion.
Our engineers can quickly mobilize to gather data from physical inspection and measurements or by reviewing as-built installation drawings of equipment to set up practical 2D & 3D models. These models accurately predict stresses, strains, displacement, fatigue, ratcheting, vibration, and thermal heat transfer to assist in determining failure modes.
