Storage tank and pressure vessel engineering

Founded in 1990 by engineers from the industrial boiler-making sector in Sedan and Dunkirk, CMPEA has established itself as a benchmark player in storage tank engineering (petroleum and industrial) and pressure vessel sizing.

Today, CMPEA is a strategic subsidiary, integrated into the VINCI Construction ecosystem, serving Entrepose Contracting projects worldwide and external industrial customers (energy, oil, gas, chemicals).

Our areas of expertise

Atmospheric storage tanks (oil & industrial)

CMPEA carries out studies and calculation notes for atmospheric tanks, in accordance with the main codes: CODRES Div. 1, API 650, API 620, BS 2654, DIN 4119, EN 14015.

Our services cover all components: ferrules, bottoms, conical or spherical roofs, associated structures and equipment.

A long-standing specialist in LNG infrastructures, CMPEA works on cryogenic tanks, in particular in accordance with API 620 and EN 14620.

Our teams size :

  • Internal and external walls
  • Foundations and insulation
  • Load-bearing elements and associated equipment

taking into account thermal and seismic loads.

CMPEA provides sizing and verification services forpressure vessels:

  • Spheres above ground or under slopes
  • Buried or cradled balloons
  • Process columns and associated equipment

Main standards: CODAP (Div. 1 & 2), ASME VIII (Div. 1 & 2), PD 5500, EN 13445, EEMUA 190.

CMPEA intervenes for :

  • Check calculation notes and drawings supplied by third parties
  • Conduct compliance reviews (codes, regulations)
  • Recommend technical solutions in the event of anomalies, doubts or repair requirements

For existing tanks and equipment, CMPEA carries out :

  • Serviceability analyses (e.g. API 653, CODRES Div. 2, EEMUA 159)
  • Thickness loss and time projection studies
  • Scenarios for restoring compliance in the event of changes in product, pressure, temperature, or wind/seismicity maps

CMPEA designs the networks and fire protection systems associated with tanks and spheres:

  • Sprinkler systems and foam
  • Specific equipment for floating or geodesic roofs

in compliance with major codes such as NFPA 11, NFPA 13, API 2000, GTDLI, etc.

CMPEA designs and verifies :

  • Lifting systems for complete tanks or sub-assemblies (lugs, frames, slings, jacking chairs)
  • Specific projects: decanters, gasometers, blast furnace components, water turbine supports, etc.

These studies are designed to ensure maximum safety, taking into account operating conditions, transitory phases (assembly, lifting, repair) and local constraints.
