Design registration for buried pressure vessels
Pressure Vessels are registered in accordance with CSA B51 ‘Boiler, Pressure Vessel and Pressure Piping Code’. The standards governing the design and construction of boilers and pressure vessels are the ASME Boiler and Pressure Vessel Codes except as otherwise detailed in CSA B51 or the regulation.
Designs of pressure vessels that have to be buried underground, must satisfy conditions that arise due to the nature of the buried environment. The applicant must demonstrate that the vessel can safely withstand the external loading imposed by the material, structures, and activity above and around the vessel.
Other governments or agencies may also have requirements that the applicant will need to address prior to the installation or operation of a buried pressure vessel. We recommend that the installers/owners of buried pressure vessels also contact their local municipalities and fire departments.
To register a design:
- Submit a completed design registration application form (CRN/PRN/BCLD).
- Provide documentation to verify that the design conforms to the applicable code/requirement. Refer to a checklist here.
- For more than one design, please complete a separate application and collate documents by design.
- Only one set of drawings, calculations and application form is required for each design.
- Submit paper copy of the application, by mail or in person, to our Vancouver office. Mark the envelope - Attn: Engineering Design Registration.
Note: Incomplete application packages will not be processed.
Design registration process
- The design registration package will be reviewed to verify that all requirements have been met.
- Upon satisfactory review, the vessel design shall be assigned a BCLD (BC Limited Design) .
- A registration letter indicating the BCLD, date of registration, manufacturer’s name, description of the vessel, drawing numbers, conditions and any other pertinent information will be sent to the applicant.
- A separate invoice will be forwarded for the fee.
- The average time for completing the design registration process is 20 to 30 business days, upon receiving a completed application.
Note: No other documents will be stamped or returned to the applicant.
Step 1: Obtain an installation permit
A permit is required to install and operate a boiler. See here for information on obtaining a boiler installation permit.
Step 2: Inspection
Following the registration acceptance, the vessel installation and its piping shall be inspected and hydrostatically tested to a safety officer’s satisfaction before being placed in service. Refer to boiler inspections for more details.
Step 3: Operating permit
Obtain an operating permit that allows the operation and maintenance of a regulated product or equipment. An operating permit is issued once the safety officer is assured that all design requirements have been complied with and that the vessel is properly installed. For details on how to get an operating permit, see here.
