The Refinery Scheduler is part of the refinery Economics & Scheduling team.
The team has the primary responsibility of managing and optimizing the hydrocarbon production of the refinery, which includes the valuation and selection of crude and feedstock, defining and monitoring targets for process unit operations, right through to the blending and delivery of products to our customers.
Our goal is to deliver the right product to the right place on time and maximize the integrated margin for the site and across the different lines of businesses.
The Refinery Scheduler uses inputs from Supply and Manufacturing to develop, optimise and execute an evolving and robust refinery schedule.
Tracks delivery and makes required adjustments.
Works with Economics and Basic Data team to improve presentation in models in order to jointly maximize margins.
The work scope of refinery schedulers may vary according to the assigned area of scheduling responsibilities namely
Depending on the assigned areas, the below main accountability's apply :
Process Units (PU) Scheduling :
Provides schedule and steers for the PU.
Issues and communicates E&S guidelines to manufacturing operations which clearly specify targets on PU intake, operating modes, run down qualities, contingencies plans and utilities balances.
Explains economic drivers and triggers.
Takes actions to mitigate the effects of an unplanned disruptions / shutdown.
Constructs projections of intake and products / components and balances
Crudes / Feed-stocks Scheduling :
Schedules the arrival and delivery of crudes and feed-stocks (including chemical feeds) to ensure their availability in the necessary quantities and qualities to meet commitments and product quality constraints, optimise stock and asset utilisation.
Takes proactive actions to mitigate the effects of the early or late arrival of shipments.
Actively contributes to crude review teams and supports crude Optimisation efforts.
Products and Logistics Scheduling
Converts the refinery Production Plan into component / product blend schedules that meet blending quality requirements while minimising quality giveaway, stock outs and demurrage costs.
Resolves prospective imbalances in components.
Ensures products availability in the necessary quantities and qualities to meet commitments and stock levels.
Ensures that the day-to-day orders and instructions to the oil movements are prepared in conformance with the Production Plan.
Uses Optimisation tools typically including both Aspen Petroleum Scheduler (aka Orion) and Multi Blend Optimiser (MBO).
