Our client needed to show that the corroded header could continue in use to avoid an unplanned shutdown.
We have extensive experience of fitness for service assessments and can respond quickly to our clients’ needs.
The efficient and safe operation of structures and equipment such as pressure vessels, offshore platforms and pipelines is vital for their continued profitable operation. Often there is a requirement for demonstrating that continued operation of critical components will be safe until maintenance can be carried out in the next shutdown.
In this example Frazer-Nash provided a very rapid response to an oil major, providing valuable results when they most needed them. Survey data had shown that there was significant material loss on a header, and they needed to show that it was safe for continued use until it could be replaced.
An API 579 Level 3 assessment is the accepted method for showing that a component is fit for further operation. In order to carry this out a finite element model of the header was created to run in Abaqus.
