About Becht Engineering's Fitness-for-Service Web-based Application
|
The BechtFFS program is a web-based fitness for service software program designed to assist operators/owners in evaluating equipment items which have developed defects in service. The BechtFFS program is compliant with API 579-1/ASME FFS-1, Edition 2016. The software is also compliant with Fracture Mechanics Assessments per ASME BPVC 2015 Section VIII, Division 3, Article KD-4.The quantitative calculations performed in BechtFFS assess the structural integrity of the flawed component and ultimately provide a recommendation whether the component should be taken out of service and retired or repaired, or is fit for continued service.
The software’s calculation methodology was developed by Becht’s API 579-1/ASME FFS-1 experts. Our FFS experts include developers of the API 579-1/ASME FFS-1 guideline document. A number of our FFS experts are current or past members of the API 579-1/ASME FFS-1 committee, including several committee vice-chair members.
BechtFFS is easy to use, with a paged format that provides logical input sequences and comprehensive pop-up help for all input pages.
The web-based format allow users to begin using it immediately once logon credentials are approved. The software can be used from any device with an Internet connection. The software is compatible with mobile devices. Finally, the web-based format ensures that users are always working with the most up-to-date version of the software.
Paid-for-Becht FFS Consultation is also available from the software’s dashboard, so that you can quickly connect with one of our FFS experts. We guarantee a quick response!
The software allows easy sharing of FFS assessment data with other BechtFFS users. The application gives the user the option of either storing ffs data on the Becht server or keeping input files locally on their own network or PC.
The software generates a series of reports for each assessment module, from summary to detailed reports documenting the outcome of the assessment. The user can select the format of the report from HTML, Excel, Word and PDF. The assessment types are shown in the below table:
