Package neqsim.process.mechanicaldesign.torg

package neqsim.process.mechanicaldesign.torg
Technical Requirements Document (TORG) framework for process design.

This package provides a structured approach to managing Technical Requirements Documents (TORG) that specify design standards and methods to be used in process design. A TORG typically defines:

  • Project identification and metadata
  • Applicable design standards per equipment category (NORSOK, ASME, API, DNV, ISO, etc.)
  • Company-specific design requirements and guidelines
  • Environmental design conditions (temperature, seismic zone, etc.)
  • Safety factors and margins
  • Material specifications

Key Components

TechnicalRequirementsDocument

The main data class representing a TORG. Built using the builder pattern for flexible construction. Supports defining standards per category or per equipment type.

TorgDataSource

Interface for loading TORG documents from various sources (CSV, database, API).

CsvTorgDataSource

CSV-based implementation supporting both standards-focused and master file formats.

DatabaseTorgDataSource

Database-based implementation using the NeqSim process design database.

TorgManager

Manager class for loading and applying TORG to process systems.

Usage Example

// Create TORG manually
TechnicalRequirementsDocument torg = TechnicalRequirementsDocument.builder()
    .projectId("PROJECT-001").projectName("Offshore Gas Platform").companyIdentifier("Equinor")
    .addStandard("pressure vessel design code", StandardType.ASME_VIII_DIV1)
    .addStandard("separator process design", StandardType.API_12J)
    .addStandard("pipeline design codes", StandardType.NORSOK_L_001)
    .environmentalConditions(-40.0, 45.0).build();

// Apply to process system
TorgManager manager = new TorgManager();
manager.apply(torg, processSystem);

// Or load from CSV file
manager.addDataSource(CsvTorgDataSource.fromResource("designdata/torg/projects.csv"));
manager.loadAndApply("PROJECT-001", processSystem);

CSV File Format

The CSV data source supports a standards-focused format where each row defines one standard assignment: 

PROJECT_ID,PROJECT_NAME,COMPANY,DESIGN_CATEGORY,STANDARD_CODE,VERSION
PROJ-001,Platform A,Equinor,pressure vessel design code,ASME-VIII-Div1,2021
PROJ-001,Platform A,Equinor,separator process design,API-12J,8th Ed
