TAR Support Point of ViewAugust 2015DRAFT Turnaround Improvement Value1.AgendaTurnaround Check Points2.Case Study3. DuPont TAR planning process leads to successful executionTurnaround Planning process Next Operation CyclePlant ProductionFeed Out Date Production DateProblematic TurnaroundEffective and Efficient TurnaroundSavingsTAR optimization focuses on effectiveness and efficiencyEffective Turnaround management minimizes the unexpected events that lead to unnecessary costs and throughput losses Lower Cost and DurationHow to improve TAR valueLonger IntervalsIs TAR scope measured against that unit shutdown is required to perform work and all items will be risk assessed?Are the TAR intervals at a optimum point in reference to Solomon benchmark?`Are slowdowns or units outages used to minimize TAR work?Are cost and schedule Solomon targets visible and closely monitored by the leadership team? Are TAR additional work (after scope freeze) and discovery work (TAR window) managed with rigor?Are SD, SU and capital projects schedules fully integrated and optimized?Are there contracts in place to incentivize better cost and duration?Does the organization understand the constraints for shorter TAR intervals?Are the logistics (contractors, materials, equipment) managed effectively?Are all management systems efficient and integrated (CMMS, controls, scheduling)?Is the work estimated based on norms with site specific adjustments? How effective are the controls to manage contractors, cost and schedule?More Effective OrganizationHow well are the TAR roles and responsibilities defined and communicated ?What is the level of compliance with TAR standards ?Can safety requirements (CoW, Facility Sitting, Fatigue Mgmt.) be optimized? Better Safety and QualityAre there contracts in place to incentivize safety and quality?Can TAR QA be performed using ANSI Z1.4 standard sampling model?TAR value improvement is achieved through 4 value leversAreas for Investigation Lower Cost and Dura
