Design registration for boilers and pressure vessels without ASME certification

Boilers and pressure vessels manufactured outside Canada and the US, and that are not constructed with full ASME Boiler and Pressure Vessel Code compliance, can follow the procedure below to register their designs. Manufacturers should submit documentation and evidence that the quality control system of the manufacturing facilities and  procedures are equivalent to that of:

  • ASME Section I for Power Boilers;
  • ASME Section IV for Heating Boilers; or
  • ASME Section VIII for Pressure Vessels.

Documentation provided for registration must demonstrate that the design, materials, and construction are equivalent to the applicable ASME Code.

Designs have to be registered prior to construction of the boiler or pressure vessel by the manufacturer, owner, user, or their authorized agent.

To register a design:

  1. Submit a completed design registration application form (CRN/PRN/BCLD).
  2. Provide documentation to verify that the design conforms to the applicable code/requirement. Refer to a checklist here.
  3. For more than one design, please complete a separate application and collate documents by design.
  4. Only one set of drawings, calculations and application form is required for each design.
  5. 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 followed by Technical Safety BC

  1. The design registration submission will be reviewed to verify that all requirements have been met.
  2. Upon satisfactory review, the vessel design shall be assigned a BC Limited Design number (BCLD).
  3. 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.
  4. A separate invoice will be forwarded for the fee (see Fees below).
  5. The average time for completing ​​​​​​the design registration process is 20 to 30 business days, upon receiving a completed application.

No other documents will be stamped or returned to the applicant.

Next Steps

Step 1: Stamping BCLD#

  1. The vessel nameplate shall be stamped with the assigned BCLD #. The stamping shall be witnessed by the authorized inspection agency’s shop inspector.

Step 2: Manufacturer’s Data Report (MDR)

MDR is the final authorization by the National Board that the vessel complies with the code of construction and is certified for use.

  • A copy of the MDR, shall be completed for the finished vessel and send to to Technical Safety BC Attn: Engineering Design Registration. ASME data reports are not to be used as the vessel will not be stamped with a ASME Code stamp. 
  • The MDR shall list all the information required for MDR’s in the ASME Codes as well as the signature of the manufacturer’s representative and the inspector from the authorized inspection agency.
  • A copy of the nameplate or stamping to be put on the vessel. 

The nameplate or stamping shall list all the information required by the ASME Codes and allocate space for the stamping of a BC Limited Design Number (BCLD #).

Step 3: Obtain an installation permit

A permit is required to install and operate a boiler. Refer here for information on obtaining a boiler installation permit

Step 4: 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 5: 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
