The Process
The tank maintenance Scope Development Process that Virtual Tank Solutions has perfected has been able to identify various savings opportunities by engaging experienced tank maintenance resources during the planning, development, and execution of tank repairs. Effective management of Storage Tank Turnarounds is a complex and demanding function. Budget overruns, schedule delays and adverse Safety and Environmental exposure are all potential consequences of inadequate scope development. Our goal is to help save you time and money by quickly evaluating your tank repair needs and highlighting the most effective way to perform the repair. We can pinpoint savings opportunities in scope reduction, material costs, and schedule improvements.
Improvement opportunities from utilizing our process:
- Reduced tank maintenance costs – up to 25%
- Reduction of tank turnaround duration – up to 50%
- Improved asset reliability through better compliance with repair codes and specifications
- Improved project controls:
- Clearly defined goals and objectives
- Early identification of risks
- Baseline costs and schedules
- Quality and Safety awareness
- Detailed field execution plans
