AVEVA E3D 3.1 Plant Design Setup: Database Hierarchy, Catalogs, and Multi-Discipline Federation

AVEVA Everything3D (E3D 3.1) operates on a proprietary object-oriented database architecture (DBS) managed through Multiple Database (MDB) definitions. Unlike file-based CAD systems, E3D enables hundreds of piping, structural, and electrical engineers to work simultaneously in a federated live model environment. The fundamental administrative hierarchy follows: - **WORLD (/*):** Top-level project universe. - **SITE:** Primary physical area or battery limit (e.g., `SITE-ISBL-PROCESS-UNIT-01`, `SITE-OSBL-TANK-FARM`). - **ZONE:** Discipline-segregated containers within each site (e.g., `ZONE-PIPING-HOT-SYSTEMS`, `ZONE-STRUCTURAL-PIPE-RACK`). - **ELEMENT:** The individual engineering entities (PIPE, BRAN, EQUI, SUBE, STRU, FRMW). By enforcing discipline-specific write databases (DESI, CATA, ISOD) and shared read databases, database corruption and concurrent locking bottlenecks are entirely eliminated.

A plant model is only as accurate as its underlying piping catalogue. In E3D, modeling cannot proceed until piping specifications (SPECON) are authored and validated against project piping material specifications (PMS). The development sequence includes: 1. **Piping Component Data (PARAD):** Define standard parametric dimensions for flanges (ASME B16.5), elbows (ASME B16.9), fittings, gaskets, and valves per ASME B16.10. 2. **Text & Nominal Bore Tables:** Set up nominal pipe sizes (NPS), metric equivalents (DN), and standard wall thicknesses (Schedule 10, 40, 80, 160, XXS). 3. **Connection Types & Compatibility Rules:** Ensure weld-neck (WFN) flanges automatically mate with butt-weld ends while raised face (RF) gasket compression tolerances are enforced. 4. **Branch Table Matrix:** Establish permissible branch fittings (Tee, Reducing Tee, Weldolet, Threadolet, Stub-in) based on header versus branch diameter ratios.

The ultimate business value of intelligent 3D modeling is zero site clashes during field erection. Deep Ocean implements a three-tier clash filtration protocol: - **Tier 1 (Hard Clashes):** Physical interferences between pipe-to-pipe, pipe-to-structure, or pipe-to-equipment. Tolerance: 0 mm. - **Tier 2 (Clearance Clashes):** Infringements into operational envelope boundaries, valve handwheel access zones, instrument removal envelopes, and forklift haulage pathways. - **Tier 3 (Insulation Clashes):** Contact between insulation cladding and neighboring civil foundations or structural columns. Using automated clash matrices, thousands of potential field interferences are resolved during engineering, safeguarding EPC schedules from multimillion-dollar turnaround overruns.

Once a piping branch status achieves model freeze, automated extraction tools produce constructible deliverables directly from the database: - **General Arrangement Drawings (Draw Module):** Multi-discipline orthographic layouts with intelligent annotation callouts, Section views, and terminal point tie-in schedules. - **Isometrics (Isodraft Module):** Single-line fabrication isometrics featuring cut-pipe lengths, weld maps, bill of materials (BOM), and non-destructive examination (NDE) percentage tags. - **Pipe Support Schedules:** Automatic extraction of support location tables referencing standard support detail drawings (hanger, guide, anchor, trunnion).
