Engineering & Fabrication Capabilities
TNI combines a multi-discipline design team (piping & structure, process, tanks & vessels) with hands-on fabrication management, so our drawings go straight to the shop and site changes are minimised.
Engineering organisation
The engineering department is led by the Engineering Manager with three discipline groups: Piping & Structure, Process and Tanks & Vessels. Design engineers and draftsmen produce models and drawings, while the Fabrication Manager and Procurement team secure materials and fabrication schedules.
Design capabilities
| Phase | Deliverables | Software |
|---|---|---|
| Basic design | Plot plan, GA layout | AutoCAD |
| FEED & 3D modeling | Piping routing, skids/modules, steel structures (platforms, stairs, handrails), pipe supports, cable trays | AutoCAD Plant 3D, Navisworks Manage |
| Detail design & shop drawings | Piping arrangement, skid assembly, face piping, frame detail, support detail, structure shop drawings, isometrics | AutoCAD Plant 3D |
| Material take-off (MTO) | Pipes, valves, fittings, bolts and gaskets extracted directly from the 3D model | AutoCAD Plant 3D |
| Tanks & pressure vessels | API 650 tanks, ASME VIII-1 vessels, hygienic tanks, FRP and PVC/PE tanks | AutoCAD, PV Elite |
| Stress analysis | Critical line list, support loads, nozzle loads, vibration and fatigue checks | CAESAR II |
Fabrication capabilities
- Stainless steel equipment: storage and mixing tanks, IBC/square tanks, static mixers, filter housings, vent filters, resin traps, venturi ejectors, sleeve pipes.
- Skid packages: pump, chemical dosing, sampling and instrumentation demo skids, complete with frame, piping, valves and instruments.
- Piping & structures: stainless/carbon steel process piping, hygienic piping, pipe supports, platforms, stairs and handrails.
- Typical materials: SUS304/304L, SUS316L and carbon steel; other materials as specified.
