Answers for engineering leaders.
Common questions from procurement and engineering teams evaluating a design partner.
What industries does Perpetual TechSolutions serve?+
We serve Oil & Gas, Marine, Shipbuilding, Offshore, Heavy Engineering, Industrial Equipment, Renewable Energy, Automotive and Process Plant industries worldwide.
What mechanical engineering services do you offer?+
End-to-end mechanical engineering — concept design, 3D CAD modeling, GD&T detailing, DFM/DFA, prototyping and manufacturing support across ASME, API, DNV and ISO frameworks.
Do you provide engineering support for Oil & Gas projects?+
Yes. We deliver piping engineering, pressure vessel design (ASME Sec VIII), storage tank design (API 650 / 620), skid design and stress analysis for upstream, midstream and downstream operators.
What does your reverse engineering workflow look like?+
3D scanning of the legacy part, point-cloud to CAD conversion in SolidWorks or Creo, GD&T recovery, drawing generation and DFM review — typically 2–4 weeks depending on complexity.
Which FEA software do your engineers use?+
We work in ANSYS Mechanical and Abaqus for linear, non-linear, thermal, fatigue and modal analysis, with reports aligned to ASME BPVC and client-specific acceptance criteria.
Can you run CFD simulations for our equipment?+
Yes — ANSYS Fluent and CFX for internal/external flow, thermal management, mixing, combustion and multiphase problems, delivered with mesh-independence and validation studies.
Do you handle full piping engineering scopes?+
We cover PFD/P&ID, isometric drafting, stress analysis (CAESAR II), pipe support design, MTO and plant modeling in AVEVA E3D, PDMS, Plant 3D and Navisworks.
How do you support manufacturing after design release?+
DFM/DFA reviews, tolerance stack-ups, fixture and tooling design, vendor drawings, first-article inspection support and shop-floor liaison until production sign-off.
