HRSG Pressure Parts Replacement

As your Heat Recovery Steam Generator (HRSG) advances in service life, it is advisable to assess the replacement of pressure components. This proactive evaluation aims to fortify the structural integrity of your unit, mitigate operational and maintenance costs, and extend the overall operational lifespan of the plant.

How can we support?

As your Heat Recovery Steam Generator (HRSG) advances in service life, it is advisable to assess whether some of the components that make up the pressure boundary may need replacing. The objective is to assure the structural integrity of the unit for the remaining design/operating life, or to eventually extend that life if desired, while minimizing disruptions and future O&M costs.

The first step in the process of deciding on pressure parts replacement is to perform a detailed engineering assessment. As performed by Tetra Engineering, it provides a sound basis for decisions on pressure part replacement by delivering a detailed evaluation of the condition of the components, the operational risks in keeping or replacing and if requested, a Front-End Engineering Design (FEED) study.

‍Pressure Parts Replacement Process

Engineering & Procurement of Pressure Parts

Tetra Engineering can support in the engineering of new pressure parts through two different approaches.

Engineering review of turnkey vendor submittals
Design of new pressure parts (for shop fabrication by others)

In the first case, Tetra Engineering can provide guidance on design changes such as specifying different grades of material (to resist FAC for example) or layout (to improve performance in a cycling regime)

Installation of New Pressure Parts

Tetra Engineering provides field support and supervision during the installation & fabrication of the new pressure parts.

On-site Commissioning

Tetra Engineering can provide an engineering review of commissioning procedures as well as on-site support to witness the commissioning activities such as hydrotesting.

‍
