Job description
It's fun to work in a company where people truly BELIEVE in what they're doing! We're committed to bringing passion and customer focus to the business. SUMMARY OF THE ROLE The Sr. Scheduler, TAR is responsible for building, maintaining, optimizing, and controlling the integrated Turnaround execution schedule across all levels of the schedule hierarchy — from the Level 1 Milestone Schedule through the Level 3 Integrated Schedule — ensuring all TAR activities are logic-tied, resource-loaded, and sequenced for maximum efficiency, minimum duration, and safe execution. KEY RESPONSIBILITIES Safety Leadership Demonstrate proactive safety leadership to the TAR team. Schedule Development & Build Develop the Turnaround master schedule using P6 or equivalent scheduling software, including critical path, float analysis, and resource leveling. Create the P6 project with a WBS structure aligned to the Cost Breakdown Structure (CBS) and the TAR Systemization Plan. Import work pack activities from STO into P6 via the P6 Sync API service that transfers work package activities, calendar assignments, activity relationships, and activity codes. Assign calendars — define shift patterns (12-hour shifts, day/night, critical path vs. auxiliary) within Primavera P6. Add and verify logic ties — supplement and validate Finish-to-Start, Start-to-Start, Finish-to-Finish, and Start-to-Finish relationships between all activities. Add operational activities into the integrated schedule — including rundown, purge, decontamination, isolation, ramp-up, PSSR, commissioning, and startup sequences — in coordination with Operations. Resource Loading & Leveling Resource-load all Level 3 schedule activities — assigning craft codes and hours per activity. Generate resource histograms by craft from P6 to identify peaks and over-allocations. Resolve over-allocations by adjusting sequence (using float), splitting activities, adjusting crew sizes, or adding shifts — then re-run the CPM calculation to confirm no critical path impact. Produce the final resource histogram for Steering Committee review and approval. Critical Path Management Run the CPM calculation in Primavera P6 to identify the critical path and near-critical paths, then validate with the TAR team. For RGLNG, ensure that the primary driver for the turnaround frequency — the turbo compressor inspections, which are also identified as the critical path determining the duration of each turnaround — is managed proactively. Conduct daily CP status reviews in the daily TAR meeting during execution. Produce a CP look-ahead daily during execution. Identify CP variance in real-time and develop a CP recovery plan. Escalate to the Steering Committee immediately if cumulative CP slippage exceeds 1 day. Schedule Optimization Conduct a schedule optimization workshop during Phase 4 (Develop), after the initial schedule build and before baselining. Apply optimization techniques including: line-by-line review to validate durations; crew augmentation to reduce CP activity duration; shift pattern optimization (moving CP work to 24/7, auxiliary to day shift only); pre-TAR work maximization (scaffolding, staging, prefab before shutdown); post-TAR work shift for non-essential finishing work; parallel execution of independent paths; method changes (in-situ repair vs. removal); scope combination to reduce isolations/permits; and 3D model/SIMOPS review to validate access and concurrent work. SIMOPS Management Identify all activities occurring in the same physical area at the same time, assess SIMOPS risks (crane lifts, hot work, confined space entry, scaffolding, blasting), apply separation rules, document conflicts and resolutions in the schedule notes, and validate with the 3D plant model where available. Schedule Baseline & Change Control Establish the schedule baseline at the end of Phase 4 after all work packs are Level 4 (Locked), schedule optimization is complete, SIMOPS review is complete, res
