A Planner/Scheduler for a "Bottom of Barrel" (BOB) Project in the oil and gas or refining industry is responsible for developing, maintaining, and optimizing project and maintenance schedules for activities focused on processing the lowest-value or less-desirable components of crude oil. Key duties include creating Work Breakdown Structures (WBS), defining task logic, estimating durations, and utilizing project management software like MS Project or P6 to build detailed Gantt charts and critical path analyses. This role involves close collaboration with engineering, maintenance, and operations teams to coordinate activities, manage resources, report progress, identify risks, and ensure project objectives are met on time and within budget, according to Quest Global and WTS Energy.
