ISODRAFT User Guide
Design Requirements : SPOOL
SPOOL
The SPOOL module allows the user to:
•
Define the contents of the spool drawings, independent of the AVEVA E3D™ pipe and branch hierarchy,
•
Add spool breaks to the design model, interactively;
•
Create numbering data for welds, pulled bends, parts, spools, and joints.
A Spool Drawing (SPLDRG) in SPOOL normally forms a single isometric in ISODRAFT (although it may be plotted over a number of sheets). Each SPLDRG contains a number of Spools (fabricated assemblies) and Fields (erection parts) connected as a continuous piping network. The spooling data is defined in the Fabrication database, from where it is cross-referenced to the DESIGN database.
The user defines their spool drawing by selecting pipes and components that form a logical interconnected network, from the graphical display. Spools and Fields are automatically set where changes in the SHOP flag status occur. The user can also change the SHOP flag on a component; force a Spool Break between two components; and add additional field welds, either on a component p-point or in a length of tube, to further split up the piping network. To provide even greater control, the user can also set the SFLimit (spool/field limit) attribute on the SPLDRG to BRAN, PIPE, ZONE, SITE or WORLD (the default). This will force a spool break at any change of element at the specified hierarchic level; for example, at every change to a new Pipe.
Once all the elements have been added to the spool drawing the user can automatically number the spools, parts, welds, pulled bends and joints. These numbers can be easily updated if the user makes changes to their spool drawing or the design is changed.
Once the user has defined and numbered the spool drawings they can be plotted using ISODRAFT. Normally one spool drawing is shown on an isometric. Alternatively, the user can produce isometrics showing either a single spool or a network of spool drawings.
Further instructions on using SPOOL can be found in the chapter Pipework Spooling of the Pipework Design User Guide.
