In the Oil & Gas and Petrochemical industry most of the plants are designed and built to last more than 30 years and many of them have already more than that.
Because of their process, most of the Oil & Gas and Petrochemical plants are running continuously 24 hours a day, 365 days a year.
These full duty operations makes very difficult all the maintenance operations and any day of shutdown will have major financial impact.
In the same time the Health, Safety and Environmental (HSE) requirements are a must at all times.
So stopping an Oil & Gas and Petrochemical facility is a major decision to be taken far before maintenance operations are needed.
The major challenges in this activity lie with completing the activities and restore the Reliability and Integrity of the facility within the defined premises of duration as per the Corporate Business Plan.
Turnaround entails an extensive seamless planning, resource mobilization and optimization to make it successful in this resourced scarce environment.
Typically the planning takes 12 to 18 months for an execution ranging around 2 to 4 weeks hence the whole lifecycle should be considered as a project from its inception to realization.
During Turnaround execution the proper monitoring of the whole jobs / activities is required to avoid any delay / slippage from the execution plan.
