Vessel Re-rating 

If you find that your vessel is not rated to meet your specific needs, re-rating your equipment may be an option. Re-rating your vessel may allow you to increase your equipment's design temperature, pressure, or both. 

We provide full equipment and process engineering services from start to finish. Our field operations team will visit your site to evaluate your equipment so our engineers can perform the necessary calculations.  We will then develop a plan to modify the equipment to meet your new duty requirements. Our service team will implement the plan and re-purpose the vessel at your facility.  Once your re-rated vessel is ready for service, we will provide as-built and/or code documentation for your records.
