About The Position

The Sr. Scheduler, TAR builds, maintains, optimizes, and controls the integrated Turnaround execution schedule across the schedule hierarchy, from Level 1 Milestone Schedule through Level 3 Integrated Schedule. The role ensures TAR activities are logic-tied, resource-loaded, and sequenced to support efficient, safe execution and minimum duration. The position develops and manages the Primavera P6 schedule, including work-pack integration, calendars, logic ties, operational activities, resource loading and leveling, critical-path analysis, optimization, SIMOPS coordination, baseline and change control, progress tracking, reporting, and recovery planning. The scheduler coordinates with Operations, Discipline Leads, the TAR team, and the Steering Committee, and contributes to integrated planning and scheduling processes and closeout lessons learned. The role operates in a complex construction environment, indoors and outdoors and in variable weather conditions. It involves exposure to moving mechanical parts, electrical circuits, and potentially distracting noise. The employee must be able to wear required PPE, travel to company work locations, move throughout the facility, and perform the physical activities described in the posting. Confined-space entry and work at elevated heights may be required.

Requirements

At least 5 years of turnaround scheduling experience in LNG, Oil & Gas, or petrochemical industries.
Advanced proficiency in Primavera P6, including CPM calculation, resource loading and leveling, baseline management, and multi-calendar scheduling.
Experience with SAP PM integration and STO scheduling systems, such as Prometheus STO P6 Sync.
Experience managing integrated execution schedules for large-scale turnaround events involving 300+ personnel and 1,000+ activities.
Exceptional working knowledge of CMMS systems such as SAP or similar.
Proficiency in critical-path methodology, resource loading, and earned value management.
Ability to interpret engineering drawings and documentation, including P&IDs, isometric drawings, and general arrangement drawings.
Advanced proficiency in S-Curve generation, schedule variance analysis, and productivity reporting using Power BI or Excel dashboards.
Strong understanding of SIMOPS management, shift scheduling, and fatigue-management principles.
Excellent communication skills, including presenting schedule status, variances, and recovery plans to senior leadership and the Steering Committee.
Knowledge of schedule hierarchy concepts (Levels 1–4) and WBS design principles.
Ability to wear required PPE and meet the stated physical demands, with or without reasonable accommodations, including moving throughout the facility, standing or sitting for a full shift, and lifting items up to 20 pounds without assistance.
Ability to communicate clearly by radio, phone, and verbally.
Must verify identity and eligibility to work in the United States and complete the required employment eligibility verification documentation upon hire.

Nice To Haves

Bachelor's degree or equivalent industry experience; a technical degree or NCCER certification is preferred.
Primavera P6 certification or demonstrated advanced training is highly preferred.
Experience in schedule optimization workshops and critical-path management.

Responsibilities

Demonstrate proactive safety leadership to the TAR team.
Develop the Turnaround master schedule in P6 or equivalent, including critical-path and float analysis and resource leveling.
Create a P6 project with a WBS aligned to the Cost Breakdown Structure and TAR Systemization Plan; import work-pack activities through the P6 Sync API and configure calendars and activity logic.
Coordinate with Operations to add operational activities such as rundown, purge, decontamination, isolation, ramp-up, PSSR, commissioning, and startup.
Resource-load Level 3 activities, generate craft resource histograms, resolve over-allocations, and produce the final histogram for Steering Committee review and approval.
Calculate and validate critical and near-critical paths; proactively manage turbo compressor inspections as a turnaround duration driver for RGLNG.
Conduct daily critical-path status reviews and produce daily look-aheads during execution; identify variance, develop recovery plans, and immediately escalate cumulative critical-path slippage exceeding one day to the Steering Committee.
Conduct a schedule optimization workshop during Phase 4 and apply duration, crew, shift, sequencing, pre- and post-TAR work, method, scope, and access optimization techniques.
Identify and assess SIMOPS conflicts, apply separation rules, document resolutions in schedule notes, and validate against the 3D plant model where available.
Establish the schedule baseline after work packs are Level 4 (Locked), optimization and SIMOPS reviews are complete, resources are loaded and levelled, and required approvals are obtained.
Capture baseline metrics, including planned duration, critical-path duration, labor hours, activity count, peak headcount, and planned S-Curve.
Manage post-baseline changes and document critical-path variances exceeding four hours in a Schedule Variance Report; coordinate scope-driven changes.
Track progress, update P6 with actuals, manage deviations and resequencing, and support daily TAR meetings and shift handovers.
Measure progress using physical percent complete, milestones, and earned hours.
Produce daily schedule, S-Curve, resource, schedule variance, and Steering Committee reports according to the stated cadence.
Initiate and apply schedule recovery actions, including crew increases, shift extensions subject to fatigue-management approval, additional shifts, resequencing, method changes, and expedited logistics.
Coordinate with Mechanical, E&I, and Process Discipline Leads to validate durations, sequencing, and resource needs.
Participate in the development, implementation, and ongoing support of RGLNG's Integrated Activity Planning & Scheduling process.
During Phase 7 closeout, analyze actual schedule performance against baseline and contribute lessons learned to the After Action Review.
Perform other duties and activities as required; duties may change.
