A turnaround (TAR) event budget includes several components derived from estimated direct man-hours and specific budget factors. These budget factors, organized by calendar year within a six-year budget cycle, are stored in the TAR Budget Factors table. The Refining Turnaround Group provides the default budget factors for each calendar year.
When setting up a TAR event and associating units with it, users can assign default budget factors to both the event and the associated units. After assigning these default values, users have the option to adjust the budget factor values as needed.
This flexible approach allows accurate budget planning, while also accommodating adjustments tailored to specific TAR event requirements.
The overall budget for a turnaround (TAR) event includes several components, calculated using historical data and estimated man-hours for accurate cost estimation. Each component and its calculation method are as follows:
|
Budget Portion |
Calculation Method |
|
Default Miscellaneous Material |
Uses a calculated miscellaneous material factor derived from historical material expenditures per direct man-hour for completed turnarounds at the site. This factor is multiplied by the estimated direct man-hours for the turnaround event to allocate the miscellaneous material costs. |
|
Default Rental Equipment |
Uses a calculated rental equipment factor based on historical rental equipment expenditures per direct man-hour for completed turnarounds at the site. This factor is multiplied by the estimated direct man-hours to allocate rental equipment costs. |
|
Default Pre-Turnaround |
Uses a calculated pre-TAR factor derived from historical pre-TAR expenditures per direct man-hour for completed turnarounds at the site. This factor is multiplied by the estimated direct man-hours to allocate pre-TAR costs. |
|
Default Post-Turnaround |
Uses a calculated post-TAR factor based on historical post-TAR expenditures per direct man-hour for completed turnarounds at the site. This factor is multiplied by the estimated direct man-hours to allocate post-TAR costs. |
|
Default Operation Factors |
Uses a calculated OPS factor derived from historical OPS expenditures per direct man-hour for completed turnarounds at the site. This factor is multiplied by the estimated direct man-hours to allocate Operation costs. |
|
Default Inflation |
Calculated based on an inflation rate and the number of years into the future for the turnaround event. |
|
Default ID Ratio |
Estimates indirect personnel or man-hours based on planned direct personnel or man-hours. |
|
Default Contingency |
Applied as a percentage of the overall turnaround budget, reserving funds for unforeseen expenses during turnaround execution. |
|
Default Electrical Support (Hrs/Days) |
Defines the expected hours per day for temporary electrical support by electricians to address unplanned electrical needs during the turnaround. For example, if two electricians work 10 hours during the day and two work 10 hours at night, this totals 40 hours per day. This factor is used to estimate electrical support man-hours. |
|
Default B-Pad Support (Hrs/Days) |
Specifies expected daily hours for direct man-hours at the bundle pad during turnaround execution. For example, if two boilermakers work 10 hours during the day and two at night, totaling 40 hours per day. This factor estimates bundle pad support man-hours in the budget. |
