Master Document Deliverable List

Instrumentation & Control - All Project Phases

This document provides a comprehensive Master Document Deliverable List (MDL) for an instrumentation and control project, covering all major phases: Conceptual Design, Front-End Engineering Design (FEED), and Detail Design (EPC). The list is categorized to follow a logical engineering workflow.

  • Rough Instrument Count: A bulk estimate of I/O based on preliminary equipment lists.
  • Budgetary Cost Estimate: A high-level cost estimate for C&I (e.g., +/- 30% to 50%).

Phase 2: FEED (Front-End Engineering Design)

Develops the conceptual design into a well-defined project basis, allowing for a more accurate cost estimate (+/- 20-30%) and forming the basis for the EPC bids.

  • Definitive Control & Shutdown Philosophies: Fully developed versions of the core philosophy documents.
  • Basis for Design (C&I): The foundational document for C&I, detailing all codes, standards, and specific project requirements.
  • Draft Instrument Index & I/O List: A preliminary but comprehensive list of all instruments and I/O signals.
  • Preliminary System Architecture: A detailed diagram showing controllers, servers, workstations, and network topology.
  • Critical Instrument Data Sheets: Data sheets for long-lead time items (e.g., control valves, complex analysers) or technically complex instruments.
  • Preliminary Cause & Effect (C&E) Diagrams: Draft C&Es outlining the primary shutdown logic.
  • Package Interface Strategy: Defines the C&I interface requirements for major vendor packages.
  • Control Room Concept/Layout: Preliminary layout and design of the main control room.
  • Main Cable Routing Concept: Drawings showing the high-level routing for main cable trays and trunks.

  • Functional Design Specification (FDS): Translates Control Narrative into specific logic/HMI requirements.
  • HMI/Graphics Design Specification: Defines look and feel, color standards, and navigation for operator displays.
  • Cause & Effect (C&E) Diagrams: Matrix or logic diagrams for SIS (ESD) and F&G systems.
  • System Cabinet/Panel Layout Drawings: General arrangement and layout for system/marshalling cabinets.
  • Power & Earthing Philosophy (Inst): Defines power sources, UPS, and instrument earthing.
  • Instrument Power Calculations / Load List: Calculates power consumption to size UPS/power supplies.

3.4. ⚙️ Field & Installation Design

Drawings showing *how* and *where* field devices are physically installed.

  • Instrument Location Layout Drawings: Plan drawings showing physical location of instruments, JBs, and local panels.
  • Instrument Hook-Up (Installation Detail) Drawings: Standardized drawings for piping/wiring of each instrument type.
  • Junction Box Termination/Wiring Diagrams: Shows internal terminal arrangement and wiring for each JB.
  • Cable Routing/Tray Layout Drawings: Plan drawings for main and subsidiary cable tray routes.
