Piping

Spooling

SPOOL is the pipework spooling module for AVEVA E3D™. It splits the pipework design into logical sections (spools) ready for fabrication. The spool data can then be output as isometric drawings using ISODRAFT. Refer to the ISODRAFT User Guide for further information.

SPOOL works with Spool Drawings (SPLDRGs), which are created by selecting an interconnected network of piping components to be added to the drawing. Once the user has selected the elements, the application checks that the selections from a valid piping network.

Spool Drawings contain a number of complete Spool and Field elements, divided by Spool Breaks, where a SPOOL is defined as a run of piping components and tube that is connected during fabrication and a FIELD is an individual or group of piping components that is connected on-site during the erection phase Spools cannot be split across Spool Drawings.

Spool Breaks are normally defined by the software, when the application detects a change in the status of the Shop Flag (where the Shop Flag indicates whether the component is included in a fabricated assembly (SHOP) or fitted during the erection phase (FIELD)). The user can also force spool breaks manually, at joints where the Shop Flags are the same on all sides, and add Welds, to split pipes, in the design.

By setting the SFLimit (Spool/Field Limit) attribute for a SPLDRG to either BRAN, PIPE, ZONE or SITE, a spool break is enforced at any change at the corresponding element level.Database Usage

SPOOL uses two databases:

•

Fabrication database - contains all the spooling data.

•

DESIGN database - contains all the design data for the project.

SPOOL has full read/write access to the Fabrication database but has only limited access to the DESIGN database, only being allowed to change attributes relevant to the fabrication of the pipework (for example, specifying Field Welds).

Database Structure

The Fabrication database structure descends from the World level (usually represented by the symbolic name /*). The administrative levels below this (and their AVEVA E3D™ abbreviations) are Department (ISODEP) and Registry (ISOREG).

The database level below Registry (and its AVEVA E3D™ abbreviation) is the Spool Drawing (SPLDRG), which is the main operational unit of the database. Each Spool Drawing can represent a continuous network of piping components and tube within the overall piping design The Spools and Fields that make up the Spool Drawing are held directly below it in the database hierarchy.

The DESIGN database also descends from the World level, below which are the administrative sub-levels Site and Zone. In the case of piping design data, the lower administrative levels (and their AVEVA E3D™ abbreviations) are Pipe (PIPE) and Branch (BRAN).

Together, these hierarchic levels give the following overall format
