Accountabilities:
Maintain, validate, and continuously enhance the refinery LP model to accurately represent refinery configuration, process unit performance, operational constraints, product specifications, feedstock characteristics, and economic drivers.
Maintain, develop, and optimize the APS Scheduling model to accurately reflect refinery operation, logistics constraints, inventory management requirements, and scheduling limitations.
Ensure LP and APS models accurately represent current refinery operating constraints and business requirements, enabling effective planning, scheduling, optimization, and margin maximization.
Act as the focal point within the Production Planning & Scheduling function for all LP and APS modelling activities, coordinating closely with Process Engineering, Operations, Commercial, and other relevant stakeholders.
Proactively manage the monthly LP and APS model update cycle, ensuring all model inputs, assumptions, operating parameters, constraints, and crude data are reviewed, validated, and updated in a timely manner.
Deliver validated and up-to-date LP and APS models within agreed planning and scheduling deadlines to support business decision-making.
Coordinate and implement model updates resulting from operational changes, process unit modifications, catalyst changes, debottlenecking initiatives, performance improvements, and new business requirements.
Perform routine plan-versus-actual analyses to identify gaps between model predictions and actual refinery performance, determine root causes, and implement corrective model improvements.
Provide model-based insights and recommendations on refinery performance, operational constraints, feedstock selection, planning accuracy, and value improvement opportunities.
Maintain and govern the refinery crude assay database, ensuring data accuracy, integrity, completeness, and timely updates.
Support crude evaluations, feedstock flexibility assessments, operational studies, and refinery optimization initiatives through robust modelling and assay management.
Perform LP optimization studies, sensitivity analyses, economic evaluations, and scenario modelling to support business decisions and identify value-maximizing opportunities.
Develop and maintain reporting systems, dashboards, visualization tools, and automated solutions to improve planning, scheduling, and modelling effectiveness.
Support the Production Planning & Scheduling department with reporting, dashboard development, data analytics, digitalization, and process automation initiatives.
Prepare and issue monthly modelling status reports and management updates covering model performance, update progress, outstanding actions, improvement initiatives, and key modelling activities.
Maintain comprehensive documentation of model assumptions, operating limits, yields, constraints, methodologies, and change history to ensure model governance and transparency.
Key Deliverables:
Accurate and validated monthly LP and APS models delivered within agreed deadlines.
Reliable crude assay database and modelling data management.
Timely identification and closure of plan-versus-actual modelling gaps.
Regular management reporting on modelling performance and improvement initiatives.
