• Review instrumentation and control design bases, engineering specifications, instrument indexes, instrument datasheets and I/O lists.
• Assess DCS architecture, control system configurations, system redundancy and network communication arrangements.
• Review control narratives, functional descriptions, control logic diagrams, alarm philosophies and operating interfaces.
• Verify instrumentation selection, sizing, ranges, accuracy, materials and suitability for operating conditions.
• Review interfaces between field instrumentation, DCS, Safety Instrumented Systems (SIS), Fire and Gas (F&G) systems and packaged equipment.
• Assess instrumentation and control interfaces associated with LPG storage, transfer, regasification, boil-off gas and flare systems.
• Review alarm management arrangements, alarm prioritisation, setpoints and operator interface requirements.
• Verify hazardous-area instrumentation selection and compliance with applicable explosion protection requirements.
• Review control system communication networks, instrumentation cabling, junction boxes and interface documentation.
• Assess vendor documentation, technical specifications, equipment datasheets and system integration test plans.
• Participate in multidisciplinary design reviews, HAZID, HAZOP and SIL workshops, where applicable.
• Identify technical deviations, design discrepancies, integration risks and non-conformances.
• Verify compliance with applicable South African regulations, SANS and relevant international standards.
• Coordinate instrumentation and control interfaces with process, electrical, mechanical, piping and safety disciplines.
• Support technical-query resolution during procurement, construction and installation.
• Participate in selected Factory Acceptance Tests (FAT), Site Acceptance Tests (SAT), loop checks, function testing and system integration testing.
• Support pre-commissioning, commissioning, start-up readiness and handover activities.
• Maintain engineering review records and track technical comments through close-out.
• Provide technical recommendations and escalate significant control system or instrumentation risks.

TECHNICAL RESPONSIBILITIES

• Provide senior-level instrumentation and control systems engineering expertise.
• Review and verify engineering deliverables within delegated technical authority.
• Assess DCS architecture, field instrumentation and control system integration.
• Verify compliance with engineering specifications, applicable standards and project requirements.
• Identify instrumentation, alarm management, control system and interface risks.
• Support engineering quality assurance and resolution of technical non-conformances.
• Coordinate technical interfaces across multidisciplinary engineering and construction teams.
• Maintain clear technical documentation and support reliable system operation.
