| RE-SCREEN AND AUDIT. RE-MEASURE THE EMISSION READINGS |
| The leak detection camera can be used to highlight any initial problems after start-up. Normal practice, is to periodically rescreen and remeasure the emissions. Where customers have their own in house monitoring teams, the process and readings can be audited. |

| REPAIR, REPLACE, OVERHAUL |
| Where possible components are repaired on-line, through ‘nipping’ up or retightening. Depending on the work load during a shutdown, a program of equipment overhaul, replacement or repair can be drawn up for areas of concern. |

| RECORD EMISSIONS IN THE DATABASE, CORRELATE VALUES TO PLANT LEAKAGE, REPORT FINDINGS |
| The components are monitored with TVA measuring equipment or the plant is screened using a leak detection camera. Readings are recorded in our EMD software system. The results are analysed to establish a repair program. Plant leakage correlation and monitoring analysis reports are generated. |

| TAG COMPONENTS IN LINE WITH THE P&ID NUMBERS,
MODIFY THE LINE DRAWINGS IF NECESSARY |
| Using the information taken from the process drawings, an identification tag is placed on the corresponding valve. Notes are taken as to the safety requirements and position of each piece of equipment and any necessary changes are made to the process drawings. A monitoring route is then devised to provide a continuous trial. |

| IDENTIFY PROCESS LINES AND COMPONENTS |
| The process line diagrams are studied to compile a list of parts and components that need monitoring. Each component is logged and recorded onto a work list for future screening. Utilisation of the line drawings allows a safe low of work during monitoring. |
