Professional Engineering

QSC provides specialist engineering and technical verification support for industrial equipment, pressure-retaining components, mechanical structures and nuclear and non-nuclear applications.

Engineering services include design calculations, code assessment, technical review, structural verification and the preparation or assessment of engineering documentation, according to the applicable project requirements.

The objective is to support manufacturers, contractors and equipment owners in achieving technically documented and code-compliant engineering solutions. Design-by-Analysis (FEA) is performed in-house, and calculations are signed by QSC's responsible engineers in the jurisdiction the project requires.

Structural Engineering

  • Structural design and load assessment
  • Stress and deformation calculations
  • Static and dynamic loading; seismic assessment where applicable
  • Support structures and industrial steel structures
  • Equipment foundations and interfaces
  • Lifting arrangements and transport support calculations
  • Structural fatigue assessment
  • Independent review of calculation reports

Pressure Vessel Engineering

  • Pressure vessel design and mechanical calculations
  • Shell and head thickness calculation
  • Nozzle reinforcement and opening assessment
  • Flange and bolting design
  • External pressure and buckling analysis
  • Local stress assessment
  • Fatigue analysis
  • Thermal stress and expansion
  • Support, saddle, skirt and lifting calculations
  • Design pressure and temperature assessment
  • Hydrostatic and pneumatic test-condition review
  • Repair and modification engineering
  • Design review and final calculation documentation

Heat Exchanger Engineering

Shell-and-tube exchangers, pressure parts, tubesheets, nozzles, shell and channel components, thermal expansion, pressure and mechanical loading, supports, design verification, documentation, fabrication inspection and test review.

Process and heat-transfer (thermal) design is distinct from mechanical / code design; each assignment states which applies. TEMA and project specifications are referenced where relevant.

ASME Section VIII Division 2

  • Design-by-Rule
  • Design-by-Analysis (FEA), performed in-house
  • Stress classification
  • Limit-load and buckling assessment
  • Fatigue assessment
  • Local stress analysis
  • Nozzle and support evaluation
  • Calculation reports
  • Material and fabrication review
  • Testing requirements and design verification

ASME Section VIII Division 3

Division 3 covers the construction of high-pressure vessels within its specified scope. Support includes mechanical design, high-pressure component assessment, applicable stress and fatigue analysis, materials, joints, welding, inspection, testing and documentation requirements.

Professional Engineering Support for USA & Canadian Projects

QSC provides Professional Engineer (PE / P.Eng.) sign-off for projects in all US states and Canadian provinces, through its responsible engineers licensed in each jurisdiction.

This covers technical calculations, design review, project-specific engineering documentation and sealed (PE-stamped) calculations to US state or Canadian provincial requirements.

A Professional Engineer (PE / P.Eng.) license is issued by the relevant state or province. ASME is not a PE licensing authority.

Typical Deliverables

  • Design calculation reports
  • Independent calculation reviews
  • Stress and fatigue analysis reports
  • Design verification statements
  • PE / P.Eng. sealed calculations for USA and Canada
  • Repair / modification engineering packages
