| Sustainable migration path |
|
The experienced engineering team carries out a plant and control system audit. The sustainable and flexible architecture of Yokogawa's control system means
that only the obsolete control units need to be changed over, allowing existing equipment to be retained to the maximum extent. Strategies for increasing plant safety, avoiding project cost over-runs, and increasing plant availability are put into place. |
|
| New control concepts tested in advance |
|
| While the design and fabrication proceed, other process application specialists review the plant control strategies and incorporate new control concepts. This is thoroughly tested by simulation, almost always with a full replica simulator. Testing proceeds separately from the manufacture of control equipment, providing low risk engineering processes for projects with short outage times. |
|
| Plant outages minimized |
|
| Once the plant outage begins, existing control equipment is quickly removed, without disturbing existing cabinets and cables. The new factory-assembled and tested control equipment is installed, and connections made to existing terminals and cables. Commissioning and testing of the new control equipment commences almost immediately. |
|
| Safe return to service |
|
| As the outage concludes, operating staff "run up" the plant with the confidence that comes from having undergone extensive training on the plant simulator.
With the newly migrated system, the power plant is set for many more years of safe, reliable and competitive operation. |
