A turnaround work package for one exchanger, the steps that moved
Oil out is about six months away, and 3,126 job packs are needed. This one, a critical pack, covers a reactor effluent exchanger on the hydrocracker. The agents draft it from the last three packs, whose wording never changed.
demoThe exchanger, the crew, the pads and the hours are sample data.

38 steps from three past packs: 31 kept, 5 changed, 2 stale
Turnaround plannerThis pack turned up in five past turnarounds, and the agents read the last three. All 38 steps were carried across, each with its source. Against 604 plant changes, two steps are no longer true. Four lessons were found, one of which does not apply, and the estimate came to 2,056 hours from closed work orders.

Six blinds on the list, and a bypass that needs a seventh
Turnaround plannerStep 1.3 is stale. A plant change added a 2-inch warm-up bypass on the shell inlet, and the last pack reused the six-blind list. That opening held the bypass on a locked closed valve under its permit, and a closed valve is not a blind. The agent proposes seven blinds and hands the new one to the isolation coordinator.

The crane pad now has a pipe rack across it, and the last crew lost 9 hours
Turnaround plannerStep 2.9 still sets the crawler on the north pad at 58 feet, using the last lift plan. A plant change built a pipe rack across that pad. The last crew moved the crane on the day and lost 9 hours, and nobody fixed the pack. The agent proposes the south pad under a new lift plan from the rigging engineer.

The plant change record: a new pipe rack across the north half of the pad
Turnaround plannerThe source opens as filed: the change that built the rack to carry new hydrogen and utility lines. Its review asked about access for operations but did not name crane positions or the bundle lift. The as-built survey left 26 feet clear on the pad. Nobody carried that change into the pack, so the last crew found the rack on the day.

Studs galled three times, so step 2.2 goes to tensioners
Turnaround plannerLast time, the pack broke the 44 channel cover studs with a torque wrench and heated seized nuts. The lesson matcher shows the studs galled at three turnarounds with the same action written each time, and the lesson cost 11 hours in one of them. The agent proposes hydraulic tensioners, every fourth stud, so no nut turns under load.

The planner accepts step 2.2, and six decisions remain
Turnaround plannerThe planner accepts the stud change with the reason that the proposal stands as written. The ladder marks step 2.2 accepted and moves on to the next changed step. Each of the seven steps that moved needs its own decision: accept, edit, or reject with a reason. Kept steps carry across with their sources and need no decision, though the planner can still open any of them.

Nine checks to make on the pad before the pack can be signed
Field walk coordinatorOnce the planner has decided every step, someone must go and see. The field walk writer lists it: whether the old pad is blocked, whether the new pad has room and firm ground, and the boom swing path. Stud height above the nut, tensioner clearance and the bypass flange follow, then the lift plan and the new blind on the master list.
