FRP, steel and thermoplastic tanks for water, chemicals and process plants. We calculate every load case, design the laminate and prepare the documents the inspector asks for.
Calculation, laminate, documentation and the training of the people who build it.
EN 13121 and ASME RTP-1API 650 and EN 14015| Material | Typical equipment | Design codes |
|---|---|---|
| Composite (GRP / FRP) | Storage tanks, process vessels, scrubbers, ducts | EN 13121-3 · ASME RTP-1 · BS 4994 |
| Steel | Atmospheric storage tanks, pressure vessels | API 650 · EN 14015 · EN 13445-3 |
| Thermoplastic (PP, PE, PVDF) | Chemical tanks, basins and pits | DVS 2205 · EN 12573 |
| Structural composites | Wings, panels, marine structures | ISO 12215 · class rules · laminate theory + FEA |
Each report lists the governing load combination for every component, so the inspector can follow the numbers without calling us.
Liquid height × densityHoop and axial stresses through the full fill height.
Design ± mbarShell and roof buckling under internal vacuum and overpressure.
EN 1991-1-4Shell buckling when empty, overturning and anchor loads.
EN 1998-4 · TBDY 2018Impulsive and convective liquid mass, base shear and sloshing height.
EN 1991-1-3Roof laminate, walkways and platforms.
Local loadsReinforcement pads and local stresses at every opening.
Lug positionsLifting lugs and shell stresses during handling and erection.
Hold-downAnchor bolt loads and foundation reactions.
Design factorResin heat-deflection limits and long-term strength reduction.
FatigueStrain limits for tanks that fill and drain every day.
Send the drawings and the duty. You receive a calculation report the inspector accepts, a laminate schedule your shop can build from, and answers when your client asks questions.
Tanks outlive their original paperwork. We assess what is standing in your plant and tell you what it can still safely do.
Specifications and tender files that hold suppliers to a measurable standard, followed by technical review of what they deliver.
When a composite structure fails, we establish why and put it in a written report others can rely on.
In Europe and Türkiye, EN 13121 is the main standard for GRP tanks and vessels. Projects specified to US practice use ASME RTP-1, and some older UK specifications still call for BS 4994. We design to whichever standard your contract names.
Diameter and height, roof and bottom type, the stored medium and its density, design temperature, design pressure and vacuum, the site location for wind and seismic loads, the nozzle list and the required standard. A general arrangement drawing helps if you have one.
Wings, chassis and crash structures designed ply by ply, checked with FEA and built as prototypes.
