Services
Calculation work, not drafting
Each service is a defined calculation package with clear inputs, assumptions and deliverables — sized for project peaks, specialist problems or independent checks.
Pipeline calculations
Buried and above-ground pipelines, stations and pig traps: soil interaction, anchors, crossings — gas, water, CO₂ and H₂.
Learn more →Dynamic analysis & vibration
Slug, PSV reaction, compressor and pump packages, vibration screening and troubleshooting.
Learn more →Steel structures
Pipe racks, skids, platforms and equipment supports to Eurocode 3: seismic, lifting, transport, connections.
Learn more →Vessels, tanks & FEA
Pressure vessels, heat exchangers, API tanks, saddles, lifting lugs, nozzle local stresses and FEA.
Learn more →Independent review
Third-party checking of stress models, reports, load cases and proposed modifications before they reach the client.
Learn more →From real projects
Calculation models, not stock photos
Screenshots from the studio's own models: piping packages, pipelines and stations, steel structures and FEA.
Why engineering companies engage us
Ing. Gianludovico SpizuocoMechanical engineer, piping stress analysis specialist
A senior specialist, directly on your calculation
You talk to the engineer who builds the model and signs the report — no account managers, no hand-offs.
Ing. Gianludovico SpizuocoMechanical engineer, piping stress analysis specialist
- Direct access to a senior calculation specialist from scope definition to final report.
- Independent capacity for complete work packages during workload peaks.
- Interfaces solved together: pipe flexibility, equipment nozzles, supports and steel structures.
- Experience of design, fabrication and construction constraints — not software output alone.
- B2B delivery under NDA and under your procedures, in English, Italian or Portuguese.
Scope boundary: isometrics and fabrication drawings are not part of the standard service unless explicitly agreed.
