Optimizing Turnaround Management for a Petrochemical Refinery

A leading petrochemical refinery faced significant challenges during the 2018 Turnaround event.

Project size

Plant Capacity: 55,000 bbl/day
Turnaround: 600 people on site per shift
during Execution Phase. Duration: 8
weeks. Budget: 70 million euro. 18.000
activities, 2000 work packages. 260,000
Direct Field man hours.

1 Challenges

▪ Transition complexities, including a vacant Lead Scheduler position.
▪ Lack of alignment between Capital Projects, Turnaround, and EPC.
▪ Operational inefficiencies leading to schedule and budget overruns.

2 Advando approach

▪ Conducting a Comprehensive Workflow Review leading to the
development of a centralized tool.
▪ Implementing a digital Turnaround management tool for
enhanced task control and work package planning.
▪ Transitioning to Advanced Dynamic Scheduling Methodology
from conventional scheduling technique.

3 Key takeaways

▪ Planning & Scheduling require collaboration across teams.
▪ Detailed planning, meta-data, & Plan-2-Plan Playbook with Key Milestones are
essential components.
▪ Traditional methods like Critical Path Method and Monte Carlo Simulation offer
limited value.
▪ Advanced Dynamic Scheduling Methodology (ADSM) recognizes the dynamic
nature of Turnaround schedules.
▪ Acknowledging productivity, calendar use, constraint management, and float
control for a fully integrated schedule.
▪ Trusted, experienced staff or contractors are key to success.

4 Achievements

Subsequent events (2018-2023) showed a consistent continuous improvement pattern.
Successful team alignment reduced micro-management requirements.
Implementation of cost control tool, resulting in on-budget and under-budget Turnarounds.
Improvement of the planning team with Lead Scheduler, TA Schedulers, Turnaround Planners, & Operations Planners.
Integration of Dynamic Scheduling Methodology facilitated greater adaptability and responsiveness in managing Turnaround schedules.
