Equipment shall be modeled to the latest data sheets using Parametrics whenever possible. If a suitable Equipment form is not available for a particular item of equipment, then modeling shall be performed using primitives or user defined shapes (JGC customized shapes).
Do not use primitive nozzles on the Start equipment form, as these will not report correctly. All equipment nozzles should be placed with Nozzle Manipulation.
The following items should be considered when modeling equipment:
• The level of detailing of vendor packaged units and other complicated items must be sufficient to satisfy clash requirements.
• Meet all the requirements for interference detection, including access, maintenance, safety and construction envelopes.
• Ensure equipment is recognizable for Design Review.
• Always put in a description of the equipment (equip_descr_1)
• Always put in source of information used, revision status, and date under equip_descr_2.
• Always put in the largest thickness for shell thickness when given multiple thickness.
• Always put in insulation/fireproofing requirements.
• Always try to place equipment by the placement point it is located by on the plot plan.
• Every piece of equipment should have a minimum of one datum point.
• Add datum points when required for aiding nozzle placement.
• Add all nozzles, access openings, sleeves and manways.
• Always put in nozzle service.
• Nozzle length should be face of flange to center of vessel or face of flange to tan line.
• Add all vessel davits.
• Add all vessel platforms and handrails.
• Build all equipment shown in the equipment list for your area.
• Make a ‘hold list’ for your area with any equipment on hold or for which you are lacking information and update it when necessary.

Materials Management software
MARIAN™ Overview
Purpose
MARIAN™ is a materials management and administration system for process plants. Its main applications are in design, engineering and construction of processing plants for the chemical, pharmaceutical and mineral oil industries, and for industrial pipeline construction and power plant construction. MARIAN supports materials management for all disciplines, including piping (and pipe supports), instrumentation, and structural steel equipment (such as vessels).
MARIAN provides continuous support for all processing stages of project management. This support includes the pre-project phase of parts and standards specification, design and financial planning, definition of material requirements, procurement and scheduling, pre-fabrication and installation as well as deadline and cost tracking.
Database and Application
The materials management system MARIAN consists of the database (tables) and the application (screens and lists). Users communicate with the database interactively in the application screens. The SQL database language can be used to access database tables from outside the application for the purpose of obtaining information. It should never be used to
modify data. The database system organizes associated data in tables, consisting of rows and
columns. A column has a fixed data type and name. A row consists of several named columns, or fields, which together constitute a data record. MARIAN screens display database table contents structured according to the function of the data. Each displayed data record shows a complete or partial row from the associated table, and may contain fixed values, that is, text that is not in the tables. Data from different tables are shown in separate blocks. Changes made in a block on a screen are saved in the corresponding database table. MARIAN screens, menus, data fields, command line, toolbar, and key sequences make working in MARIAN easy for users.

PDS OVERVIEW (Part1)
1. What is the Plant Design System?
Intergraph’s plant design software can be used to design any type of plant—from petrochemical plants, offshore platforms, chemical and pharmaceutical plants, consumer products (food, beverages, cosmetics, soap, paper, and so forth), to power plants, waste water treatment plants, and cogeneration facilities.Specifically, the Plant Design System (PDS) integrates many discipline-specific software modules; these modules automate the many phases of a plant design project. Instrument Data Manager is one of these modules. Designing a plant with the modular Intergraph-Zydex plant design software system comprises four phases:
- Project Setup - 2D and 3D design files, project files, databases.
- Preliminary Design - feasibility studies, cost estimates, general layouts and process flow diagrams.
- Detailed Design - process, instrumentation, piping layouts, material control.
- Design Review - 3D model walk-through.
1.1 What are the 2D modules?
PDS 2D is used to create schematic diagrams and to provide the associated reports and MTOs, and to define and purchase all equipment, instruments, pipe, and so forth, necessary to build the plant. All of the needed data is stored in databases. These are relational databases which you can query, add, delete, or edit information to suit your own or your client’s needs.
The PDS 2D modules are briefly discussed in the following sections.
1.1.1 Process Flow Diagram (PFD)
Conceptual design of a plant includes feasibility studies, cost estimates, and process simulations. Third-party process simulation packages such as ASPEN or SimSci allow engineers to perform preliminary calculations such as chemical equilibriums, reactions, heat and material balances and/or design pressures and temperatures. The data produced from these calculations are transferred to PDS where a process flow diagram (PFD) is developed.
1.2 What are the 3D modules?
PDS 3D is used to create three-dimensional plant models, create equipment models, extract isometric drawings, and perform design interference checks and equipment clashes. As with the 2D modules, all of the needed data is stored in relational databases which can be queried or edited. The PDS 3D modules are briefly discussed in the following sections.
1.2.1 Equipment Modeling (PD_EQP)
Equipment Modeling (PD_EQP) allows designers to model the equipment defined in the P&ID.
Stylistic representations of equipment items are produced, with or without nozzles, by entering data from equipment data sheets noting dimensions and weights. Upon completion, the equipment item is placed in the 3D model. Within PD_EQP, designers can create a physical envelope defining the space occupied by an equipment item along with space envelopes defining maintenance and access areas. This process is instrumental for interference checking later in the modeling process.
PDS OVERVIEW (Part2)
1.2.2 FrameWorks Plus (FWP)
Structures must be designed to carry the loads from piping, equipment, personnel and other factors to the ground. FrameWorks Plus is used to layout structural frames, foundations, slabs and walls. Piping designers, equipment modelers and structural designers, by sharing reference files, can see the location of each other’s objects. The structural engineer referencing other models can place loads in the 3D model, and apply other analytical characteristics to use with a third-party analysis solver. After a design run, the new cross section properties can be read back into the model to automatically update all the associated symbolized 2D drawings.
Other outputs can be obtained from the data model such as material lists, output to third-party steel detailing programs, interference envelopes, and graphic and nongraphic data made available to the rendering and walkthrough products such as DesignReview.
1.2.3 Piping Design Graphics (PD_Design)
PD_Design allows designers to create a 3D model of the piping and in-line instruments defined in the P&ID by routing the pipelines through space. When placing the instruments and valves, designers take into account pipeline flexibility, method of construction,and ease of access for maintenance and operations.Designers can route pipe in the 3D model as a centerline representation; moreover, a 3D shaded model can be displayed when necessary. The centerline is intelligent and contains all the information relating to a pipeline, such as the piping material class, nominal diameter, fluid code, insulation parameters, temperatures and pressures, and so
forth. The alphanumeric data required for each pipeline can be entered interactively or transferred from the P&ID. This can be done during centerline routing, or it can be added/revised later. A pipeline can be connected to a specific nozzle or routed from a point in space. Components such as valves, instruments and branches can be placed on the pipeline as it is routed. Values for the alphanumeric data—such as line sequence number, nominal diameter, material class, temperatures and pressures—can be set during routing. Interactive design checks are performed for each component placement. These checks ensure matching or compatible diameters, pressure ratings, end preparations, and other consistency criteria. Pipe supports can be modeled giving either a detailed space envelope or a logical representation of the function of the support, such as an anchor, spring, or guide.
1.2.4 Reference Data Manager (PD_Data)
Placement of the piping components is specification-driven. The reference data provides the selection criteria for the piping commodity items found in the piping job specification and piping commodity libraries delivered with the product. This data is contained in the RDB and can be used by other projects. The delivered reference data contains 140 piping materials classes, defining over 100,000 different components for pressure ratings from 125-1500 pounds. It also contains an extensive set of catalog data including 2200 engineering tables. Reference Data Manager (PD_Data) is specifically designed to define and modify the reference data for the PDS 3D modules. This reference data ensures consistency in the definition of piping specifications and commodity libraries. It is used to control and standardize the PDS 3D modules to reflect company practices and standards.
