Plant Design Project for Liquip International
Navigating the complex requirements of clean-energy infrastructure demands robust, future-ready site logistics. Partnering with Liquip International, we delivered a comprehensive structural assessment, advanced 3D equipment modeling, and complete plant layout documentation for their next-generation hydrogen upgrade program. By integrating new gaseous routing systems into the existing storage and terminal framework, we secured an optimized, safe, and fully compliant civil-industrial environment.
Executive Summary
project charter overviewUpgrading bulk liquid terminals to handle hydrogen transport introduces complex chemical, safety, and spatial layout constraints. Standard petroleum and aviation storage layouts do not possess the necessary physical spacing, specialized safety zones, or structural footing limits to handle highly pressurized gas elements. To address this, our civil-industrial team performed a rigorous factory-wide assessment of Liquip’s manufacturing layout. Utilizing high-fidelity CAD modeling and structured safety evaluations, we drafted a seamless plant layout that handles current loading arms and meters while creating dedicated, hazard-isolated zones ready for future hydrogen fuel cell and storage installations.
Mitigate gas dispersion risks by utilizing exact physical separation, continuous ventilation corridors, and protective blast blast-wall zoning within structural boundaries.
- Map existing terminal lines and highlight integration clash points.
- Zone high-pressure gaseous manifolds away from standard ignition sources.
- Draft compliant concrete footings capable of handling massive storage weights.

civil & hydraulic integrationDependencies & Interactions
system boundariesPiping alignment depends on laser audit coordinates — precise site measurements prevent line clashing during installation.
Tank security depends on reinforced slab slabs — high weight loads demand thick, structurally solid footings.
Operator safety depends on hazard zone spacing — keeping gas tanks away from active traffic prevents accidents.
Continuous flow depends on loading arm range checks — mapping swing envelopes stops collisions with structures.
Code compliance depends on standard safety rules — integrating national safety guidelines speeds up construction permit approvals.
Future expandability depends on modular piping ports — prep-placing connector nodes prevents costly retrofits later.
Key Takeaways
essential lessons- Design with safe distance offsets — keeping gaseous manifolds away from ignition points minimizes fire hazards.
- Assess foundation loading capacities — heavy gas cylinders require thicker, reinforced concrete support slabs.
- Map arm swings in 3D space — plotting fluid loading arm sweeps in CAD prevents physical collisions.
- Build in modular expansion ports — adding connector terminals simplifies future hydrogen upgrades.
- Keep storage areas well-ventilated — open, ventilated zones allow light hydrogen gas to escape safely.
- Verify floor plans on site — double-checking existing factory dimensions prevents costly routing clashes.
- Secure early safety certifications — matching layouts with national codes speeds up regulatory approval.
- Provide clear line interfaces — neat piping manifolds keep terminal connections organized and easy to service.

Frequently Asked Questions
clarifying the designWhy are standard industrial concrete slabs unsuitable for hydrogen storage tanks?
Pressurized hydrogen cylinders are extremely heavy. Standard concrete pads can crack under the concentrated weight, requiring custom-thickened slabs with heavy steel rod mesh to distribute the load.
How does the plant layout prevent explosive gas pocket accumulation?
We placed storage areas in open-air, naturally ventilated zones. This lets light hydrogen gas rise and disperse safely, eliminating fire risk points.
What specific checks were done to verify loading arm movements?
We modeled the exact operational sweep of Liquip's loading arms in CAD. This verified that hoses and metal pipes move freely without hitting structures or tanks.
How did the team integrate new piping into the existing terminal?
We conducted a detailed spatial audit of the plant. This allowed us to route new pipelines along existing pipe racks, minimizing structural costs.
What safety standards were used to define the hazardous zones?
The layout matches NFPA 2 and local Australian standards. These codes define safe offsets and spacing around hydrogen storage equipment.
How does this layout support Liquip's future business plans?
By preparing the terminal layout for hydrogen upgrades now, Liquip can expand into the clean-fuel market without needing major, expensive structural reworks later.
