Work with the usable cleaning window
A six-hour production stop may leave only four hours between equipment release and inspection. Planning starts with that usable cleaning window, not the headline shutdown length.
- Record the time at which the equipment is physically open and released.
- Reserve pump, hose and recovery positions against the other trades.
- Protect the inspection and closure time at the end of the window.
Opening condition can change the order
Record the point at which equipment is isolated, open and physically available to the crew. Reserve the pump, hose and recovery positions against other trades, then protect inspection and closure at the end. That sequence reveals the hours actually available for jetting. Planning around production and shutdown windows is therefore based on release and handback times.
