Outage Schedule
Scheduled turnaround operations and emergency mechanical overhauls at crude oil processing facilities temporarily reduce refining throughput and alter fuel supply balances. Energy traders and regional product distributors track refinery maintenance to anticipate shifts in gasoline and diesel production volumes. Planned turnarounds take place periodically to replace catalyst beds and inspect high-pressure distillation vessels.
Unscheduled shutdowns occur when sudden equipment failure or power loss disrupts process units unexpectedly. Execution timelines range from several weeks for routine unit overhauls to multiple months for major complex turnarounds.
Yield Shifts
Shutting down specific secondary processing units alters finished fuel blend balances across regional supply systems. When fluid catalytic cracking units undergo turnaround, light oleic streams and gasoline blendstock yields drop significantly. Refiners adjust crude run rates and unit cut points to optimize yield profiles from remaining active infrastructure.
Trading desks react to refinery maintenance announcements by adjusting spot market positions and securing fuel supplies from neighboring refining centers. Regional product price spreads widen as local inventories deplete during prolonged unit outages.
Regional Balances
Import cargoes from foreign refining hubs cushion local supply deficits during extended maintenance windows. Waterborne trade flows rebalance regional supply shortages when local refining capacity is temporarily offline.
