11-13-18 In summary of calculation review for Summit T-502 Calculations provided are based off the corrosion report provided by Petro Chem. Nominal thickness based off a conservative estimate that the deepest pit is equal to the wasted wall corrosion in vessel. Vessel does not need to be Re-Rated. Design 50 PSIG @ 350 °F Nominal Thickness Remaining .211” Thk. Corr. Allow. .0625” Thickness Req’d. for pressure .1253” Thk. Thickness Req’d. for wind loading .1422” Thk. Assumptions: Not having any other corrosion data, Aeon has to make assumptions for current condition of Amine Still. Deepest pit (.164”) started in wall with no previous corrosion lose using .375” nom thickness. Vessel was inspected in January of 2017 so only assuming vessel has seen 1-1/2 years of service. Remaining life calc. based on .1422” min thickness required for wind loading. Corrosion rate stays the same. Recommendation: Since Aeon will be in vessel replacing tray and downcomer supports, I recommend repairing the two pitted areas at downcomer #4 and #10 by weld overlay. Also any wasting areas of seams and any repairs Petro Chem deem necessary. Would also recommend removing top mesh pad for inspection of top head and seam. Remaining life based on Summit Midstream making all repairs recommended, we can use the .245” wall thickness remaining based on the lowest average reading in the pit chart furnished by Petro Chem. Using that for our nominal shell thickness, the remaining life calculation would give you approximately 1 year. If you have any questions, give me a call. Best Regards, Drew Norris 318-489-5770 cell

Furthermore, PetroChem will not be held liable for the manner in which the information

contained within this report is used.




ASSESSMENT:

The scans of each welded attachment were initially analyzed during data acquisition. No

usable ACFM or PAUT was obtained on a majority of the seam and circumferential welds

due to moderate to severe weld erosion/ corrosion. The bottom circumferential weld was

the only weld in good shape and no defects were detected with ACFM. UT Thickness was

performed above and below the bottom circumferential weld with nominal readings

obtained (0.379" to 0.383"). A visual inspection with a pit gauge was performed. The Tray

7 connecting ring showed severe corrosion and a through wall hole. Severe pitting was

noted in several areas of the tower shell. The most severe pit measured 0.164" deep and

was located in areas of severe pitting/corrosion. Please see attached pictures, screen

shots and UTT report.

(Per code, this should have been inspected to API 510 with an API 510 onsite. All

information contained in this report shall be calculated per code and by engineering. No

repair recommendations will be included in this report.)

Section 3

ASSESSMENT:

A visual inspection with a pit gauge was performed. The inspection was performed from thetop circumferential seam and below. The demister was in place at the time of inspection. TheTray 7 connecting ring showed severe corrosion and what appears to be a through wall hole.Severe pitting was noted in several areas of the tower shell. The most severe pit measured0.164" deep and was located in areas of severe pitting/corrosion. Please see attachedpictures, screen shots and UTT report.

The bottom circumferential weld is in good shape and no defects were detected with ACFM.The scans of each welded attachment were initially analyzed during data acquisition. Anestimated 85% of the tray ring attachment welds, shell vertical and circumferential weldsexhibit moderate to severe weld erosion/ corrosion. The corrosion limited the ACFMinspection looking for cracks in the welds. No usable ACFM data was obtained on a majorityof the seams.

Note in 2017 internal visual inspection revealed internal shell corrosion/erosion throughoutthe shell and on the welds seams. Weld repairs were preformed however the locations werenot noted.

UT Thickness was performed above and below the bottom circumferential weld with nominalreadings obtained (0.379" to 0.383"). Additionally UT thickness readings were collectedbefore and after the weld on the horizontal circumferential seams of shell course 3 through 6.Note the data was collected on good base metal not on or in pitting. See UT tables in thisreport.

The data collected indicated the vessel condition needs to be reviewed and assessed.The remaining wall thickness was found to be below the corrosion allowance. Additionalreview and calculations of the data revealed the vessel shell wall is below the structuralminimal thickness requirement in Summit Midstream Mechanical Integrity Program. Seepreliminary calculation spreadsheet in this report. Based on this information the vessel isnot safe to operate, (0 remaining life). Thus see the recommendation for engineeringreview and calculations based on structural loads.


Section 4

Recommendations1. Perform an engineering evaluation of the vessel shell wall remaining wall thickness.2. Calculate the structural Tmin required for the vessel to be suitable for service.3. Calculate the remaining life based on structural Tmin.4. Remove the internal top mesh or demister pad for inspection.5. Perform visual UT thickness inspection on vessel internal top section (demister area).

Repair recommendations1. Weld repair the vessel internal shell circumferential weld seam(s) locations which are

marked on the weld(s) by PetroChem inspection.2. Weld Repair the vessel tray attachment clip weld to shell, which are marked by

PetroChem Inspection.3. Weld overlay repair the shell internal vessel wall pitting found that is greater than

.130" in depth.4. Document the X and y location of the deepest pit remaining of each shell course.

ConclusionAeon performed an engineering evaluation/calculations the vessel shell wall and determinedthe structural Tmin is .142" and .125" for the internal pressure load are the minimalremaining wall needed to operate the vessel safely. However based on the estimatedcorrosion rate the lowest allowable remaining wall thickness of .245" is needed to operatethe vessel safely. The remaining life of the vessel is 1 year based on the Structural Tmin,corrosion rate and .245" remaining wall. See the attached calculations.

Scope of WorkTUV SUD America Chemical, Oil & Gas Division was asked to perform a detailed Automated Ultrasonic Pulse Echo C-Scan Examination on the reamainig unscanned top half of T-502 Amine Still, while the equipment was out of service.The vessel was painted and the surface condition was fair. .

The purpose of this examination was to detect any potential I.D wall-loss for the accessible areas using longitudinalwaves (for corrosion mapping) looking for service related damage. This examination was focused on the "Shell".

The examination was performed in accordance with our C-UT-15, Rev-5 procedure "Automated Ultrasonic CorrosionMapping Examinations" and the calibrations documented in the "Calibration" section of this report.

TUV SUD America Chemical, Oil & Gas Division utilized a state-of-the art Multi-Channel AUT system interfaced to a2-Axis scanner and specially designed transducer for the 0º. The transducer contains a dual element 5 MHz 0°-longitudinal wave capable of resolving a .125” long by .050” (50 mils) deep notch, flaw and corrosion or pitting of .25”diameter and .050” (50 mils) in depth

Executive Summary

For the shell material examined, the lowest remaining wall detected was .131" which represents a 65.07% wall loss basedon a nominal wall thickness of .375". This area was found on Shell course 3 Scan 19.

Based on the data gathered, this equipment has been given a Damage Rating Assessment of DRA-6 COR6 Corrosion-6:Corrosion, either general wall-loss or pitting that exceeds 50% wall-loss (>50%), in accordance with the attachment“Damage Rating Assessment”. This is based on significant wall losses >50% and <50% of the nominal wall thickness.

Refer to the attached Individual Summaries, ACAD, Scan Sheet and AUT data for full details.

The examinations performed represent one of the most comprehensive inspections that can be performed on piping. Thisdata offers an excellent benchmark for any future examinations or monitoring. The overall responsibility for mechanicalintegrity of this equipment rests with the client and monitoring should be in accordance with your engineering practicesand/or RBI risk management philosophies.

TUV SUD America Chemical, Oil & Gas Division utilizes state-of-the-art computerized robotic technology and advanced ultrasonic testingtechniques to provide the oil & gas industry one of the mostcomprehensive inspection programs in our industry; AutomatedUltrasonic (AUT).

AUT is a fully automated ultrasonic inspection technique, whichutilizes a multi-channel ultrasonic imaging system and encoded roboticscanners. The major advantage of AUT is that it provides detailedinspection data at a high rate of speed with exceptional accuracy andrepeatability.

AUT is capable of inspecting pressure vessels, piping,storage tanks, and other equipment while in service forpotential service related damage. AUT offers a fullvolumetric inspection providing details on shell materialdegradation such as erosion, corrosion, hydrogenblisters, hydrogen induced cracking (HIC), and relatedinterlinking cracking.

This system can also be utilized in weld inspection forthe detection of both service and fabrication relateddefects implementing the pulse-echo or Time of FlightDiffraction (TOFD) techniques.

Advantages:· In-service examinations at elevated temperatures (Up to 650º direct scanner contact)· High-speed data acquisition, up to 30 inches per second.· Minimizes the need for costly internal entry.· Detailed information for fitness for service evaluation.· Exceptional repeatability, encoded scanning accurate to .001”.· Multi-tasking capabilities utilizing a full array of transducers simultaneously.· Optimize inspection dollar.
