Support informed decision-making, refinery optimization, operational excellence, and margin maximization through accurate modelling, plan-versus-actual deviation analysis, crude assay management, optimization studies, reporting, and automation initiatives. Act as the Production Planning & Scheduling focal point for all LP and APS modelling activities, accountable for model accuracy, timely monthly model delivery, stakeholder coordination, reporting, automation, and the provision of actionable insights that support refinery value maximization. The position will act in accordance with the OQ8 s Mission, Vision, Values & Strategies, as well as, policies, guidelines, and international standards, supported by an IT Technology platform, HSE standards, Oman s government & other legal justifications, and best international practices in consonance with national objectives. Main tasks and responsibilities Scope LP Modelling APS Modelling Collaboration Reporting & Automation 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. Enhanced planning and scheduling efficiency through reporting, dashboarding, and automation solutions. Actionable optimization recommendations supporting refinery profitability and value maximization Key interactions Internal: Liaise with the colleagues and stakeholders for day-to-day work External: 3rd Party Contractors Notable Working Conditions. Office environment, moderate to intensive computer screen use, occasional site presence
