The Rosen MFL/DEF/IMU ILi Preliminary Report was received on 12/9/2024. After reviewing the preliminary report, it was determined that twenty-four (24) anomalies reported as possible mechanical damage would require a temporary pressure reduction be issued. Prior to the temporary pressure reduction being issued, five (5) anomalies were investigated and repaired. A 10% temporary pressure reduction was implemented for the remaining nineteen (19) anomalies on 12/16/2024, to a reduced pressure of 207 psig.","truncated":false,"body_characters":741}
