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.

01

Piping stress analysis

CAESAR II and AutoPIPE models, load cases, code compliance, spring hangers, nozzle and support loads.

Learn more →
02

Pipeline calculations

Buried and above-ground pipelines, stations and pig traps: soil interaction, anchors, crossings — gas, water, CO₂ and H₂.

Learn more →
04

Steel structures

Pipe racks, skids, platforms and equipment supports to Eurocode 3: seismic, lifting, transport, connections.

Learn more →
05

Vessels, tanks & FEA

Pressure vessels, heat exchangers, API tanks, saddles, lifting lugs, nozzle local stresses and FEA.

Learn more →
06

Independent review

Third-party checking of stress models, reports, load cases and proposed modifications before they reach the client.

Why engineering companies engage us

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.
