AIR SEPARATION UNIT SPECIALIST ENGINEER - ELECTRICAL DUNCAN AND ROSS MANAGEMENT CONSULTANCIES

Lead and execute electrical engineering activities for ASU plants, including air compression, purification, cold box, cryogenic distillation, storage, and product distribution systems. Develop and review electrical design deliverables such as load lists, single line diagrams (SLD), power distribution philosophies, cable sizing and routing, lighting layouts, grounding and lightning protection systems. Design and review MV/LV power distribution systems, MCCs, switchgear, transformers, UPS, battery systems, and emergency power supplies. Prepare and check electrical equipment datasheets for motors, VFDs, soft starters, transformers, switchgear, and electrical auxiliaries suitable for cryogenic and oxygen service. Review electrical interfaces with packaged ASU units including compressors, expanders, cold boxes, analyzers, and cryogenic pumps. Ensure proper integration of electrical systems with DCS, PLC, SIS, and plant automation systems. Perform electrical studies including load flow, short circuit, motor starting, protection coordination, arc flash, and harmonic analysis. Develop and review hazardous area classification drawings and ensure electrical equipment compliance with area classifications. Participate in HAZOP, HAZID, SIL, LOPA, and QRA studies from an electrical discipline perspective. Ensure compliance with IEC, IEEE, NFPA, API, ATEX, IECEx, ISO, and Middle East client standards (Saudi Aramco, ADNOC, PDO, QP, SABIC, Maaden). Ensure electrical designs meet oxygen service requirements, low-temperature operating conditions, and high reliability standards. Review vendor and licensor documentation from industrial gas licensors. Conduct technical bid evaluations, vendor clarifications, and technical alignment meetings. Coordinate with OEMs and vendors for compressors, motors, VFDs, expanders, substations, and packaged systems. Participate in FAT, SAT, commissioning, energization, and performance testing activities. Interface with process, instrumentation, mechanical, civil, and commissioning teams. Support construction, pre-commissioning, commissioning, and start-up activities at site. Provide troubleshooting support for plant operation, reliability improvement, and debottlenecking. Ensure engineering deliverables meet project schedules, quality requirements, and client milestones.
