Deliverable Setup Methodologies
Standardized configuration workflows for grid-aligned, flange-aligned, and clash-sensitive deliverable setups in automet® FAB.

Pre-Survey Considerations

Numerous methods exist for establishing an automet® FAB deliverable depending on spool geometry and site environmental constraints. Prior to survey execution, field surveyors must verify:

  • Obstructions and interference: Presence and precise coordinates of unremovable objects adjacent to the pipe run.
  • Structural steelwork: Locations of existing structural members intended for pipe support attachment.
  • Tie-in flange parameters: Gasket/offset thickness, pressure rating, and total bolt-hole count.
  • Tie-in condition: Whether the tie-in point is open (unconnected/no blind flange) or fixed.

Primary deliverable setup configurations

  1. Grid system setup: Aligns deliverable geometry directly with overall site/platform grid coordinates.
  2. Flange alignment setup: Prioritizes minimum flange misalignment regardless of global grid rotation.
  3. Potential clash setup: Maintains specific centerline workpoints (circle fit) to avoid nearby obstructions.

Method 1: Deliverable Setup in Accordance with Grid System

Grid system setup is frequently utilized when establishing entirely new pipe routes, following existing structural steelwork, or managing complex multi-spool runs.

Key considerations

  • Surrounding physical reference points (decks, bulkheads, structural steel) are used to build the local analysis grid via the **analysis transform** function.
  • The physical orientation of spools within the surrounding environment forms an integral part of the deliverable output.
  • While necessary for routing along structural steel, this method can make complex spool geometry harder to interpret on fabrication drawings.

Method 2: Deliverable Setup in Accordance with Flange Alignment

This approach disregards overall grid orientation to prevent in-situ structural misalignment from corrupting shop fabrication dimensions.

Operational benefits

  • Improved baseline accuracy: If preliminary design dimensions contain errors, alignment fit preferences produce cleaner outcomes, allowing easy preliminary file adjustments.
  • Decoupled survey data: Grid misalignment does not distort spool fabrication dimensions; the report strictly details physical spool geometry.
  • Simplified shop build: Produces clearer, highly fabrication-friendly spool isometric drawings.

Method 3: Deliverable Setup for Potential Clash Conditions

When an object or support sits close to an existing pipe run, a **circle-fit** calculation must be performed to ensure the new deliverable routes through the exact spatial position of the original spool centerline.

1. Identifying and configuring the circle fit

Field survey notes must explicitly specify that the circle-fit center point is to be maintained during deliverable creation.

2. Analysis fit procedure

1. Set all flange fit preferences to **alignment**. 2. Uncheck the circle-fit option during initial setup and zero **Flange 01**. 3. Rotate flanges taking Flange 01 as the origin until **Flange 02** reaches zero Z elevation.

3. Text report generation and cross-check

Print the text report from the main menu and construct the deliverable while maintaining the identical X coordinate for the circle-fit center.

4. Potential clash risk

Failing to maintain circle-fit centers during deliverable creation can result in severe physical clashes at fitting locations during installation:
