07.2026 - Current
- Chevron ABU (Australian Brownfield Unit) – Upstream Gas Field Project: support mechanical reliability, asset integrity and sustaining-engineering activities for brownfield upstream assets.
- Contributed to upstream asset reliability improvement and equipment lifecycle management in brownfield sustaining activities, focusing on safe and reliable asset performance.
- Supported asset integrity criticality ranking and critical-equipment identification by reviewing equipment function, failure impact and available engineering information.
- Validated critical information in GTC-1 engineering-data management, ensuring accuracy in engineering-data and asset-information activities, including P&ID validation, asset-register validation, equipment-tag verification, data consistency and engineering-data quality checks.
- Maintain and validate asset hierarchy and equipment relationships to support reliable identification, functional-location alignment and downstream reliability/maintenance workflows.
- Apply performance-standard concepts to critical assets, linking required equipment performance, reliability expectations and maintainability considerations with engineering information.
- Support HCEM (High Consequences Equipment Management) activities for high-consequence equipment by identifying critical assets, reviewing integrity/reliability information and supporting action tracking.
- Review engineering information, P&IDs and asset registers to identify gaps that can affect equipment integrity, reliability, maintainability and sustaining-engineering decisions.
- Support digital engineering / digital-twin workflows by maintaining alignment between P&IDs, asset registers, equipment attributes and project datasets.
- Apply RCM, FMEA and RCFA/RCA principles to equipment failure modes and reliability issues; support corrective-action and maintenance-strategy recommendations.
- Prepare technical deliverables, engineering review comments and structured asset information while coordinating with multidisciplinary engineering, reliability and project stakeholders.
