Why Inline Inspection
￭ To Expose hidden Corrosion and Mechanical Damage that is in a pipeline. ￭ Repair Prevents Serious Accidents
– Extensive Property Damage– Serious Environmental Damage

Recorder Function 3 -- Block Based Compression
￭ Premise – Need “Loss-Less” compression and Corrosion is localized
￭ Process Blocks of N samples￭ Pass 1 – Calculate histogram of sample variations￭ Pass 2 – Encode the samples that have large variations with more bits￭ Pass 3 – Encode the samples that have smaller variations with fewer bits

Benefits & Possibilities
￭Higher Compliance Tools – Smaller Electronics Package￭Inspect Longer Lines – Power needed for Data Processing
reduced by 50% for 36 inch tool￭Improve Reliability – Remove 1 level of interconnect￭Improve Defect Detection and Characterization – Can
Support higher sample rates￭Smaller Traps – Consider a single body tool
