TSASK Skid Design Registration: Saskatchewan's Dedicated Program for Packaged Equipment

By Kopfkino Consulting Corp. · Published September 14, 2026 · Updated October 17, 2026 · 8 min read

Saskatchewan registers a repeatable skid as a pressure piping design under TSASK IP-2016-07-04. Submission steps, TSK-1002 data reports, nameplates, stand-alone PRD rules and 10-year validity.

Saskatchewan's skid design registration program, set out in TSASK Information Paper IP-2016-07-04, registers a packaged skid as a pressure piping design, much like a fitting registration. Once registered, the design covers unlimited identical skids, with Saskatchewan-P.Eng.-authenticated drawings, a skid nameplate, a TSK-1002 construction data report per unit, stand-alone overpressure protection, and 10-year validity.

Package suppliers selling repeatable skids into Saskatchewan face one recurring question: how is the pressure-boundary design registered? Most jurisdictions treat each skid as part of a site-specific piping system, forcing a fresh review at every installation. Saskatchewan is different: the Technical Safety Authority of Saskatchewan (TSASK) operates Canada's most explicit skid design registration program.

Saskatchewan's legal framework and TSASK's role

Pressure equipment in Saskatchewan is governed by The Boiler and Pressure Vessel Act, 1999 (SS 1999, c. B-5.1) and The Boiler and Pressure Vessel Regulations, 2017, administered by TSASK. TSASK registers designs of boilers, pressure vessels, fittings, and pressure piping systems, issuing Canadian Registration Numbers (CRNs) bearing the Saskatchewan designator "3," and participates in the nine-jurisdiction CRN Reconciliation Agreement. A CRN approves the design, not the individual unit. Submissions go through TSASK's online Design Submission Portal using TSK-series forms.

How does Saskatchewan's skid design registration program work for repeatable packages?

Information Paper IP-2016-07-04 defines a skid as "a metal plate or frame pallet used for mounting pressure piping and/or pressure equipment." Under the program:

  • The skid is registered as a separate pressure piping design, much like a fitting registration. TSASK assigns a unique skid design registration number, referenced in future registrations; repeat skids are not re-reviewed.
  • Registration expires 10 years from the registration date (suspendable earlier for cause), mirroring CSA B51's 10-year fitting cycle.
  • No design changes without TSASK approval. Email notice is acceptable; TSASK indexes a revision or issues a new number.
  • Every fabricated skid carries a nameplate showing the manufacturer name, skid serial number, and skid design registration number, attached on final acceptance after the TSK-1002.
  • Overpressure protection must be stand-alone. No inter-connected pressure relief device (PRD) common discharge headers are permitted between the skid, other skids, and/or distribution piping.
  • A TSK-1002 report is required per fabricated skid, and TSASK must be notified before fabrication begins.

What goes into the skid design submission?

Per IP-2016-07-04, the package includes:

  • Form TSK-1011 application (check "Skid design submission") plus TSK-1003 general engineering requirements.
  • A P&ID covering all pressure equipment on the skid.
  • Line lists stating size, material, schedule, maximum pressure/temperature, minimum design metal temperature (MDMT), corrosion allowance, radiography, test medium and pressure, and post-weld heat treatment.
  • A PRD list with capacities and set pressures.
  • The pressure/leak test procedure.
  • An owner letter where Category D (lethal) fluid service applies.

Critically, drawings and line lists must be stamped by a Saskatchewan-licensed professional engineer (P.Eng.) and must be "sufficiently detailed so Design Reviewers will not have to assume anything."

Why does not the 0.5 m³ piping exemption apply to registered skids?

Saskatchewan generally exempts pressure piping systems under 0.5 m³ (17.7 ft³) aggregate volume from design registration, though a TSK-1002 is still required with the site registration number. IP-2016-07-04 expressly states that the 0.5 m³ exemption does not apply to registered skid designs, and companion paper IP-2016-07-003 confirms it does not apply per-package in multi-package submissions. Splitting a system into sub-threshold skids to evade registration is not accepted in Saskatchewan.

Fabrication, welding, and the TSK-1002 data report

Fabrication rules depend on where the skid is built:

  • In Saskatchewan: welding uses ASME Section IX procedures registered with TSASK under a registered Quality Control Program or Quality Management System.
  • Elsewhere in Canada: the jurisdiction of record governs procedure registration and inspection.
  • Outside Canada: CSA B51 cl. 4.5.3 (B51-14 numbering) applies: TSASK requires the Authorized Inspection Agency name and National Board number (or equivalent), code of construction, owner's requirements, and quality-control evidence, and "strongly advises" acceptance before fabrication.

For each fabricated skid, the TSK-1002 Construction Data Report documents the completed pressure piping system (TSASK publishes a completion guide). The nameplate is attached only after the TSK-1002 is complete and the unit receives final acceptance. Note also TSASK's portable-equipment rules: for skids relocated repeatedly, PRD discharge must not connect to any header not fully contained on the skid, and new-to-Saskatchewan equipment needs an installation permit and a manufacturer's data report (MDR).

Fees and timelines (as of the 2024-07-16 fee schedule)

ItemFee (CAD)
Registration of design$225.00
Design review (minimum 2 hours)$155.00/hour
Expedited A (10 working days)$232.50/hour
Expedited B (3 working days)$465.00/hour
Alternative Registration of Manufacturer's Data Report$380.00 per data report

A second published line ($45.00 for "registration of design when review completed by TSASK") has an undefined scope distinction (likely harmonized or previously reviewed designs); confirm applicability with TSASK. All figures are as of the July 16, 2024 schedule. TSASK quotes roughly six weeks for standard design registration and about one week for data-report registration.

Practical scenario: a metering-skid product line

An OEM builds a standardized gas metering skid for Saskatchewan wellhead facilities. The first submission registers the design and TSASK issues the skid design registration number. Units 2 through 40 are fabricated identically; for each, the fabricator notifies TSASK, welds under registered procedures, completes a TSK-1002, and stamps the nameplate, no unit-level re-review. Rerating a line class later is a design change requiring TSASK approval (indexed revision or new number), and after 10 years the registration must be renewed.

How does TSASK's program compare with other provinces?

Saskatchewan's program is the closest thing in Canada to a product-line registration for skids.

Common mistakes

  • Assuming the 0.5 m³ exemption covers the skid. It does not apply to registered skid designs or per-package in multi-package submissions.
  • Interconnected relief headers. Tying the skid's PRD discharge into a header shared with other skids or plant piping violates the stand-alone protection rule.
  • Out-of-province engineer stamps. Skid drawings and line lists need a Saskatchewan-licensed P.Eng.
  • Changing the design after registration. Revisions need TSASK approval first; unapproved changes can suspend the registration.
  • Forgetting per-unit documentation. Every fabricated skid needs its own TSK-1002 and nameplate.
  • Late AIA engagement for offshore fabrication. TSASK strongly advises acceptance before fabrication starts.
  • Ignoring the 10-year expiry. Skid design registrations lapse like fitting registrations and must be renewed.

Best practices

These are engineering recommendations, not regulatory requirements; confirm current requirements with the authority having jurisdiction (AHJ).

  • Register the skid design before the first Saskatchewan sale so later units reduce to fabrication and data-report time.
  • Freeze line classes, PRD settings, and MDMT in a "registration basis" drawing set so options never become unapproved design changes.
  • Keep every fitting on the skid registered or documented as exempt; TSASK exempts standard ASME-listed Category A, B, C, and G fittings, but non-standard items need their own CRN.
  • Calendar the 10-year expiry alongside fitting CRN renewals.

Frequently Asked Questions

How does Saskatchewan's skid design registration program work for repeatable packages?

TSASK registers the skid once as a pressure piping design under IP-2016-07-04 and issues a unique skid design registration number; identical repeat skids are not re-reviewed. Each fabricated unit is documented with a TSK-1002 report and a nameplate showing the registration number.

Does the 0.5 m³ piping exemption apply to skids in Saskatchewan?

No. IP-2016-07-04 states the exemption does not apply to registered skid designs, and IP-2016-07-003 extends that to multi-package submissions.

Do skid drawings need a professional engineer's stamp?

Yes. IP-2016-07-04 requires drawings and line lists stamped by a Saskatchewan-licensed P.Eng.: stricter than TSASK's general vessel guidance, which demands stamping only where the code or reviewer requires.

Can I connect my skid's relief valves to a common header?

No. Registered skids must have stand-alone overpressure protection; inter-connected PRD common discharge headers between the skid, other skids, and distribution piping are prohibited.

What is the TSK-1002?

TSASK's Construction Data Report for pressure piping systems. One is completed per fabricated skid; the nameplate is attached only after the report is complete and the unit receives final acceptance.

How much does TSASK skid registration cost, and how long does it take?

As of the July 16, 2024 fee schedule: $225 registration plus review at $155/hour (two-hour minimum), with expedited hourly rates. Standard design registration runs about six weeks. Confirm current fees and timelines with TSASK.

How long is a skid design registration valid?

Ten years from the registration date, subject to earlier suspension for cause; the design cannot change without TSASK approval.

Key Takeaways

  • IP-2016-07-04 registers a skid as a separate, fitting-like pressure piping design. Canada's most explicit repeatable-package pathway.
  • One registration covers unlimited identical skids; per-unit obligations are the TSK-1002 report and nameplate.
  • The 0.5 m³ piping-volume exemption does not apply to registered skid designs.
  • Drawings and line lists require a Saskatchewan-licensed P.Eng.; overpressure protection must be fully self-contained.
  • Design changes require TSASK approval, and the registration expires after 10 years.
  • Fees as of July 2024: $225 registration plus $155/hour review; the alternative MDR route is $380.
