Job Description

Job Requirements

• Develop and revise instrumentation and control system drawings including P&IDs, loop diagrams, hook-up drawings, JB schedules, and cable layouts using AutoCAD.
• Use Navisworks to review and coordinate 3D models for I&C systems across multidisciplinary design environments (mechanical, piping, electrical, civil).
• Prepare layouts for field instrumentation, control panels, analyzers, marshalling cabinets, and DCS/PLC system connections.
• Collaborate with instrumentation engineers to reflect design intent, loop functionality, signal types, and control system architecture.
• Integrate vendor drawings and datasheets into project deliverables; verify compliance with project standards and client requirements.
• Support clash detection, visual reviews, and spatial coordination using Navisworks.
• Maintain proper document control and version tracking of instrumentation deliverables.
• Assist in producing as-built documentation post project execution and commissioning.

Work Experience
Required Skill Sets

• Proficient in AutoCAD 2D for I&C drafting (loop diagrams, wiring schematics, cable layouts, etc.).
• Hands-on experience with Navisworks Manage or Simulate for 3D model navigation, coordination, and clash detection.
• Sound understanding of instrumentation systems: transmitters, valves, sensors, analyzers, and their integration with control systems.
• Ability to interpret and draft P&IDs, control narratives, I/O lists, and loop drawings.
• Knowledge of industrial control systems (PLC, DCS, SCADA) wiring and architecture.
• Familiarity with instrumentation standards: ISA, IEC, API, and project-specific specifications.
• Experience preparing instrument index, cable schedules, and termination diagrams.

Good to Have Skills

• Experience with SmartPlant Instrumentation (SPI) / INtools or AVEVA Instrumentation.
• Exposure to BIM processes and integration with other disciplines (electrical, piping, civil).
• Familiarity with control panel design, cabinet GA drawings, and internal wiring layouts.
• Knowledge of hazardous area classification and intrinsic safety wiring principles (ATEX/IECEx).
• Basic understanding of loop check, calibration, and commissioning workflows.
• Prior experience in onshore/offshore facilities like refineries, LNG terminals, petrochemical plants, or FPSOs.

Qualifications
Diploma or Bachelor's Degree in Instrumentation Engineering, Electronics.
3+ years of drafting experience in instrumentation and control systems within the oil & gas or process industry.
