Definition :
In petroleum refining , turnaround means a
scheduled large-scale maintenance activity wherein
an entire process unit is taken off stream for anextended period for comprehensive revamp and
renewal. This operation involves a lot of preparations
and requires many precautions, especially at during
startup.

Turnaround Key Learning
• Dehumidification system provided in CDU & VDU column was
very effective for maintaining comfortable atmosphere insidecolumn for workmen, by maintaining temperature between 28
to 32 deg C & Relative humidity was less than 65% inside the
columns. This facility has remarkably contributed in reducing
the time mainly for huge quantum of welding / hot work inside
the column. Dehum idi f icat ion System in CDU & VDU columnDehum idi f icat ion System fo r Reactor-Riser

Turnaround Key Learning
• New idea of Exchanger cleaning bay has resulted in huge time
saving by providing central Point for Cleaning of all TubeBundles with advance Hydro jetting machines i.e.
Inside/Outside Robotic machines and Inspection (Visual &
Eddy Current Testing) was also carried out at same place which
helped in good housekeeping and keeping ISBL unit free from
Oil, Coking & Sludge and Further reduced House Keeping Jobalso.

What made it happen(from 45 to 35 Days
•Decisive Leadership and on spot decisions.
•Micro level Turnaround planning started well in advance before 18 months for
man, material , machines, job list and its work pack.
• Defined all critical jobs :
1. CDU/VDU column Revamping.
a. We treat contract manpower as our employee and provide all the facilities
like Accommodations/Food/Transport/Medical/Water/Tea-Snacks at site
only.
b. Use of new concepts and modernized gadgets e.g. providing lifts as high
as 90 Meters, Dehumidification /AC, Chemical decontamination etc.
c. Maximizing the pre turnaround activities e.g. 90% scaffolding, issuing of100% bulk material/ spares and its prefabrication/ machining and placing
in position.
d. Daily Review and making rolling plan for speedy execution.
e. Timely supply of equipment and logistics arrangements

a. Optimise the use of Pigging machines in such a way that critical Heater
handed over with in minimum possible durations.
b. Use of new concepts and modernized gadgets e.g.SAF RAD
Radiographic machines so that other jobs can be continued.
c. Heater jobs divided in multiple zones so that welding jobs can beperformed at maximum locations at a time and saved lot of time.
d. Keep standby manpower for critical activities so that job shuld not suffer
at any cost.
3. FCCU Reactor Refractory repairing:
a. Providing of Dehumidification /AC.b. Using SAF RAD Radiographic machines,Diamond cutter for refractory,
electrical and instrument testing equipment etc.
c. Using of skilled manpower and guidance from Refractory experts.
