The engineering office offers its expertise and support to various industry stakeholders in the design and sizing of components and systems. The goal is to verify the mechanical strength of equipment under operational (pressure, temperature, etc.), climatic, and seismic loads.
Your needs
Preliminary sizing, verification, revamping, calculation of on-site installation non-compliance, maintenance.
Our calculation and sizing services
Calculation services, on-site visits for expert assessments at INBs (Basic Nuclear Facilities).
The benefits
Our expertise allows us to handle a wide variety of topics. This diversity of expertise brings flexibility, responsiveness, competitiveness, and professionalism to projects.
Our methodology
Calculation methodologies are based on the regulatory context, the calculation code, and the software used.
Regulatory framework
CODETI, CODAP, ASME, EN13445, EN13480, EUROCODES, FEM, RCC-M, RCC-Mx, CODRES, API650
Industry
Petrochemical industry, nuclear industry, pharmaceutical industry, lifting equipment.
Our software
CAESAR, PIPESTRESS, BEAMSTRESS, AUTOPIPE VESSEL, ANSYS.
Calculations
Static and dynamic (seismic, vibration, and resonance), linear and nonlinear, using beam elements and/or finite elements,
Verification under elastic, plastic, and/or fatigue conditions, at room temperature and elevated temperatures,
Analytical calculations (using spreadsheets or AutoPipeVessel),
Thermal and thermomechanical calculations.
Our deliverables
Each calculation report presents the environment, the study context, the assumptions, the materials, the load cases, the validation criteria in accordance with regulations, the results, and a detailed analysis.Some examples of projects: Calculation of a 900 MW REN/REP heat exchanger, flexibility and anchoring calculations for emergency diesel generator components for the Bristol EPR, flexibility calculations for a waste heat recovery project, flexibility calculations for instrumentation lines at the Flamanville EPR, processing of installation deviation sheets for INB, and heat exchanger calculations.
Our Strengths
Our expertise allows us to offer services tailored to every need for expertise in boiler making, piping, and finite element modeling. Our expertise is based on over 20 years of industry experience and current regulations. We take the time to understand our clients’ needs and provide them with tailored solutions to resolve their issues.
