Overview

cloud Tank Designer (CTD) is a browser-based parametric 3D storage tank modeler. Define your tank by diameter, stacked shell courses, floor and roof type — fixed cone, fixed dome, or external/internal floating roof — then place nozzles, manways, ladders, and platforms directly on the 3D model.

Every design is revision controlled and stored securely in the cloud, with auto-generated screenshot thumbnails and secure read-only sharing via signed links.

Key Features

Parametric Shell & Roof

Stack shell courses with independent height and thickness. Choose flat, coned-up, or coned-down floors, and fixed cone/dome or floating (external/internal) roofs.

Nozzles & Manways

Place sized nozzles and manways on the shell, roof, or floor with elevation, angular position, and projection — real-time 3D visualization as you add them.

Ladders & Platforms

Add caged straight or spiral ladders, and roof access platforms with optional handrails, positioned by angle and elevation.

Dual Revision System

Alpha mode (A, B, C...) for work-in-progress drafts. Promote to numeric mode (Rev 0, 1, 2...) for formal issued documents. Full revision history with descriptions.

Screenshot Thumbnails

Auto-generated PNG thumbnails on every save. Displayed in the project index for quick visual identification of designs without opening each file.

Secure Sharing

Share read-only 3D viewers via signed URLs (7-day expiry). All editing tools are hidden in viewer mode. No account required for recipients.

How It Works

1
Set Tank Properties

Set the diameter, add shell courses, and choose your floor and roof type. The 3D model updates instantly.

2
Add Components

Place nozzles, manways, ladders, and platforms. Double-click any component in the 3D view to edit or remove it.

3
Save & Share

Save your design with an auto-captured screenshot thumbnail, create new revisions, and share a read-only viewer link with your team.

Calculations & Checks

  • Shell thickness: API 650 one-foot method per course, design and hydrotest against the corroded thickness, with the Table 5.6a nominal minimum checked separately.
  • Wind: AS/NZS 1170.2 from region, terrain category and importance level; the shell, fixed roof, platforms and ladders each contribute drag, giving base shear and overturning moment.
  • Seismic: AS 1170.4 site parameters applied to the API 650 Annex E impulsive and convective masses.
  • Anchor bolts: Uplift per bolt from wind and seismic against the empty steel weight, checked against the modelled bolt pattern with a suggested minimum size and count.
  • Clash warnings: Adding or editing a ladder, platform, wind girder or shell nozzle that overlaps another item asks you to keep it or cancel, and unresolved clashes are saved with the file.
  • PDF report: Export the tank calculations as a PDF with a cover page, revision history and header/footer, recomputed from the saved model.
