Worklist control and planning relates to compiling and controlling all aspects of work for a turnaround from job specification to a detailed plan. Event control ensures systems are in place to monitor performance against targets. Planning is the crucial preliminary step to meeting goals of safety, duration, cost and quality as turnarounds often fall short due to ineffective planning. The software described simplifies and automates planning, generates standardized work packages and instructions, and delivers control, enabling improved safety, a comprehensive worklist, material management, and monitoring of planning progress. This reduces duration, cost, and project management effort while increasing data utilization.
