Inspection Specific Information Richard Wallace ITC Level II

Inspection Overview This investigation is employing the use of thermographics and infra-red in order to assess the levels of sediment deposits within the process vessels indicated. The object is to provide initial sediment level assessment and to provide baseline thermograms for comparative future inspections so that levels can be monitored and trended accordingly. The baseline thermograms can then be used as a reference point against subsequent images from periodic inspections. This will allow the sediment levels to be monitored along with specific temperature readings of the vessels. The trending graph found in the lower part of the analysis page records both temperature data from each inspection and then the estimated sediment level or distances relating to the sediment settled in the separator.

Theory Deposited sediment will be visible to infra-red due to the insulating effect it has on the surface temperature of the process vessels. This means that areas of material deposit will appear with a lower temperature than areas which do not suffer from deposits as the heat from the separators/degasser will have to travel through more material, in this case sand. These lower temperature signatures can be attributed to internal deposits within so long as the external surface area is clean and not affecting the thermograms. The separators and degasser have a continuous outer shell material which means emissivity will remain constant.

Inspection methods Initial visual inspection of the site took place in order to familiarise with any irregularities or access problems. The vessels occupy an area in an elevated position which has 360 accessibility making image capture relatively straight forward. There was no insulation present on any of the vessels inspected so removal was not necessary. Images were then captured of all vessels comprehensively recording all lower sections of the vessels and any other areas which may benefit from temperature analysis. Statement The suggestions and opinions in this report are interpretations of the thermograms by the thermographer at the time of inspection. These are not definitive comments and do not claim to be absolutes. It is recommended that these interpretations be used in conjunction with other NDT inspection methods to determine the overall condition of the asset. Conclusions are not the responsibility of the thermographer as these should be drawn by the appropriate integrity personnel collating all NDT inspection data.

Executive Summary Inspection 1 - 16/09/08: This initial inspection is designed to capture the first thermograms which will be used as a baseline and reference point for each subsequent inspection. Trending between inspections can then take place in order to monitor the sediment levels within along with various temperature measurements. Inspection 2 - 23/02/09: The level appears to have risen across the length of the separator by a small % only with the most significant change coming from the irregular shape of the level now found inside. These two findings illustrate that the irregular shape could be from the sand washing/jetting trials carried out on the separator between inspections whereby an estimated 8 tonnes of sand was aid to have been removed. Despite this removal, the level has risen slightly indicating that a significant volume, possibly above 8 tonnes, has been re-deposited in the meantime.
