Methodology for Checking Mechanical Completion of New Alumina Refinery

Hi Friends,

In present post, we will discuss the major activities carried out for checking the construction completion and readiness of equipment and facilities for conducting testing and commissioning trial runs. Major activities are listed here under-

1. Verifying the installation of all equipment and completion of construction activities as per PFDs, P&IDs, ISOs and design drawings.
2. Readiness of operating and maintenance platforms.
3. Installation of sampling valves, scoop and other required system.
4. Hydro-static / pneumatic testing of vessels, lines, cranes and equipment in line with statutory guidelines.
5. Cable continuity test for electrical power supply.
6. Statutory clearances from Government officials for equipment, lines and pressure vessels.
7. Calibration as well as function checking of instruments, controls and interlocks.
8. Proper leveling and alignment of the equipment.
9. Direction of rotation of motors, fans and other rotating equipment.
10. Flushing of equipment with water for removal of foreign materials.
11. Checking the equipment for initial fill of grease and lubricants.
12. Checking of tools and tackles for normal operation and maintenance.
13. No load checking of motors in decoupled condition.
14. Dry running of all rotating equipment in circuit.
15. Vibration checking of rotating equipment.
16. Preparation of punch list of outstanding items / deviations and required changes / modifications including their priority level for changes / modifications and planning for incorporation in final as-built drawings.

These are the major activities carried out for checking the mechanical completion of the Alumina refinery project before taking up testing and commissioning of Alumina refinery.

Please put your views / suggestions / remarks / comments, if any.
