A0151944 and A0151945. This is an in-service client information inspection only.The scan plan shall be built to employ sectorial PAUT to observe the inner 1/3rd of the weld in order to quantify any signs of ID cracking. Tonote, the weld profile has been built according to available data from the U1-A form. Actual bevel angle may be different.Figure 1 - PAUT Scan Plan* See continuation report for further scope and results.Technician NameCGSB Level & Cert.

Number 20015628NAP.O. NumberScope - ContinuedWhen discontinuities are encountered that may be indicative of ID connected cracking, they shall be imaged with TOFD to determineextent and only whether the indication is crack like or not. Due to the original joint efficiency requirements, this inspection shall not be utilizedto determine acceptability of the weld in accordance to code of construction.The Bullet on the North side of the plant is called tank north, the Bullet on the South side is called tank south. The ‘direction of flow’ of thetanks is assumed to be from west to east, naming the outer most circular weld on the west side number 1. All circular welds are scanned infour sections, 12 to 3 o-clock, 3 to 6 o-clock, 9 to 6 o-clock and 12 to 9 o-clock. The longitudinal welds on the heads are scanned clockwise,naming the 12 o-clock position ‘zero’.Summary Report146 data sets were captured, giving 100% coverage of all welds for each vessel. 19 relevant indications were detected, 2 of which areinterpreted as crack like. As a cautionary note the other 17 indications may pose a risk to develop into cracks in the future. A monitoringprotocol may be wise until such time that a visual internal can be completed. Refer to Figures A and B for crack like indication detail.Detail Report - PAUT Data sets and description.Technician NameCGSB Level & Cert.

Indication 12 measures Length: 103mm (100 to 203)Height: 1.5mm (18.5 to 20). While these indications certainly appear to be ID connected, without full knowledge of the weld bevel andinternal weld profile (caps ground flush?) these has to be some caution in analysis. These indications may turn out to be undercut or smallareas of cold lap. Future monitoring to look for signs of growth would be prudent, however these indications may be easily classified withthe next internal inspection by visual or magnetic particle methods.Images of Relevant IndicationsThe following pages contain the images of both the PAUT and TOFD for the 19 relevant indications detected during the inspection.Technician NameCGSB Level & Cert.
