The Ultimate Guide: A Deep Dive into the 3D 90% Modelling Review The 90% 3D model review is arguably one of the most critical milestones in any industrial engineering project. It represents the final, comprehensive check-up before engineering drawings are stamped “Issued for Construction” (IFC). Getting this review right prevents...
Mastering the 3D 30% Model Review: A Comprehensive Checklist for Instruments and Cabling In the world of large-scale industrial projects, success is forged in the details. Before a single pipe is welded or a foundation is poured, the entire plant exists as a complex digital twin: the 3D model. One...
Key Documents This set of documents establishes the foundation and detailed specifications for the instrumentation and control system. Project Design Basis / Philosophy: Outlines the fundamental principles, codes, standards (like API, ISA, IEC), and project-specific requirements for the design of instrumentation and control systems. Cause & Effect (C&E) Matrix: A...
A comprehensive format and guide for an Instrument Index document, commonly implemented using a spreadsheet (like Microsoft Excel) or a dedicated engineering database. 1. Document Header Every page of the Instrument Index should have a standard header containing: Project Name: Project Number: Document Title: Instrument Index Document Number: Revision Number:...
An I/O (Input/Output) list for a Distributed Control System (DCS), Instrumented Protective System (IPS/ESD), or Fire and Gas System (FGS) in the oil and gas sector is typically a comprehensive spreadsheet or database. It serves as a master reference for all instrument signals connected to these control and safety systems...
An Alarm and Trip Settings document, often called an Alarm and Trip Schedule or Cause and Effect Matrix, is a critical engineering document in the oil and gas industry. It formally records all the setpoints for process alarms and automated trips (shutdowns) for a facility. The format is typically a...
Checklist and Activities: Preparations for an Instrument Engineer Before a SIL Workshop In the world of process safety, the Safety Integrity Level (SIL) workshop is a cornerstone event. It’s where the critical decisions are made about the safety layers required to protect personnel, the environment, and assets from potential hazards...
A Hazard and Operability (HAZOP) study is a cornerstone of process safety management, and for an Instrument & Control (I&C) Engineer, it’s not a meeting you just show up for. Your role is pivotal. You’re the gatekeeper of the automated systems, the alarms, and the safety-instrumented functions that act as...
