Approximately 64% of thetotal number of spools have metal loss reported within them.The majority of these are internal and are characteristic of corrosion.Mill/manufacturing faults will have been present in the pipeline since it was commissioned. Itcan be difficult to achieve the normal sizing accuracy for mill/manufacturing faults depending onwhether these metal loss features are the result of hot working or cold working of the pipe steel.Consequently, it should be noted that the sizing accuracy specified for corrosion in theInspection System Performance Specification (Appendix G) contained in the contract may notbe applicable to mill/manufacturing faults.Detailed inspection sheets for 5 of these metal loss features are provided in Section 2.Summaries of all the metal loss features are presented in Section 4.1.1.2.Pipeline AnomaliesThe following is a summary of any pipeline anomalies which have been detected on theinspection survey:ferrous metal objects: 5eccentric pipeline casings: 1dents: 4girth weld anomalies: 3shell repairs: 1patch repaired spools: 5More information on pipeline anomalies is given in the anomaly reports presented in Sections4.2.2 to 4.2.6.I nspection SummaryC0001_20AIssue 1Page1-21.3.Inspection QualityInspection data was obtained for the full length (4.0km) of the pipeline.The quality of the inspection data is satisfactory and this has enabled a comprehensiveassessment of the pipeline to be carried out.C0001_20AIssue 1Page2-12.Metal Loss Feature ReportThe Metal Loss Feature Report provides detailed inspection sheets for selected metal loss features.The metal loss features are selected for detailed analysis and reporting according to the selectionrules given in the Specification for the Pipeline Inspection Report (Appendix F).Those metal loss features that are reported on inspection sheets have predicted axial lengths,predicted peak depths and location details to the accuracy described in the Inspection SystemPerformance Specification (Appendix G).The Estimated Repair Factor (ERF) is calculated using the formula given in the Reporting section ofthe contract (Appendix F).2.1.Summary TablesThis section provides a summary of the metal loss features reported on the inspection sheets.Tables summarising the inspection sheets are provided in the following sub-sections:2.1.1.Summary of Inspection Sheets in Distance OrderThis table presents a summary of the inspection sheets with the metal loss featuressorted in order of their absolute distance from the launch.2.1.2.Summary of Inspection Sheets in Feature Selection OrderThis table presents a summary of the inspection sheets with the metal loss featuressorted in order of their selection rule.2.1.1 Summary of Inspection Sheets in Distance OrderPredicted DimensionsInsp.SheetNumberAbsoluteDistance(metres)Ext.or Int.

That is the spoolcontaining the metal loss feature has pipeline parameters equal tothose used to calculate the ERF unity curve.+ The metal loss feature is reported on an inspection sheet and is withinthe major segment.The metal loss feature is within a minor segment. That is the spoolcontaining the metal loss feature has pipeline parameters different tothose used to calculate the ERF unity curve.The metal loss feature is reported on an inspection sheet and is withina minor segment.Each pressure sentenced plot is presented overleaf.Pressure Based Pipeline Summary ReportC0001_20AIssue 1Page4-44.1.2.Pressure Based HistogramsThe pressure based histograms show the distribution of the most significant metal lossfeatures along the pipeline.Metal loss features that have been identified as manufacturing faults are not included inthe pressure based histograms.The significance of each metal loss feature has been assessed using the pressuresentencing formulae based on ASME B31 and defined in the Appendix to theSpecification for the Pipeline Inspection Report (Appendix F).Each pressure based histogram shows the distribution along the pipeline of those metalloss features with ERF values above a chosen pressure sentenced threshold.Each bar on the histogram represents the number of occurrences within a 10m section ofthe pipeline.The pressure sentenced thresholds chosen to highlight the most significant metal lossfeatures are as follows:- all metal loss features with ERF values >0.900- all metal loss features with ERF values >0.950- all metal loss features with ERF values >1.000Summarising from the histograms:1622 metal loss features with ERF values >0.90013 metal loss features with ERF values >0.9504 metal loss features with ERF values >1.000In addition, a single three-dimensional summary histogram is included which shows thedistribution along the pipeline of those metal loss features with ERF values above each ofthe chosen pressure sentenced thresholds.The pressure based histograms are presented overleaf.Pressure Based Pipeline Summary ReportC0001_20AIssue 1Page4-54.1.3.Depth Based HistogramsThe depth based histograms show the distribution of all detected metal loss featuresalong the pipeline.Twelve histograms are presented in this section:- three ungraded metal loss histograms- eight graded metal loss histograms- one three-dimensional summary histogramUngraded Metal Loss HistogramsThe total metal loss histogram shows the distribution of all metal loss featuresalong the pipeline.Each bar on the histogram represents the number ofoccurrences within a 10m section of the pipeline.The area metal loss histogram shows how much of the pipe surface has beenaffected by metal loss.Each bar on the histogram represents the total surfacearea of the metal loss within a 10m section of the pipeline.This is expressed as apercentage of the surface area of an undamaged pipe section.The volume metal loss histogram shows how the volume of metal in the pipelinehas been affected by metal loss.Each bar on the histogram represents the totalvolume of the metal loss features within a 10m section of the pipeline.This isexpressed as a percentage of the volume of metal in an undamaged pipe section.Graded Metal Loss HistogramsThe metal loss features are graded into eight categories, which are derived fromcombinations of two predicted length and four predicted peak depth categories.There is one graded metal loss histogram for each category.Each bar on thehistogram represents the number of occurrences within a 10m section of thepipeline.Pressure Based Pipeline Summary ReportC0001_20AIssue 1Page4-6Summarising from the histograms, a total of 1632 metal loss features have beenidentified within the pipeline.These have been graded as follows:1521 metal loss features with predicted axial lengths 3t.Of these:1090 have a predicted peak depth of 20%t.401 have a predicted peak depth of > 20%t and 40%t.27 have a predicted peak depth of > 40%t and 60%t.3 have a predicted peak depth of > 60%t.111 metal loss features with a predicted length > 3t.Of these:72 have a predicted peak depth of 20%t.36 have a predicted peak depth of > 20%t and 40%t.2 have a predicted peak depth of > 40%t and 60%t.1 have a predicted peak depth of > 60%t.Three-Dimensional Summary HistogramThe metal loss features are graded into nine depth categories and displayed on asingle three-dimensional histogram.

change in the nominal pipe wall thickness, or other parameter of the pipeline, has beendetected by the inspection system.This listing identifies the major and minor pipelinesegments used during the analysis of the inspection data.A pipeline segment is a section of the pipeline where the nominal wall thickness (nwt), themaximum allowable operating pressure (MAOP) and the internal design pressure of thepipe (Pi) are constant.Pipeline segments can be categorised as either major or minor segments.A major segment is a pipeline segment that has been defined by the pipeline operator inthe table provided in the Company Defined Operating Parameters section of the contract.In this table the pipeline operator specifies the locations of the start and end of thesegment and the values of nwt, MAOP and Pi that apply within it.A minor segment is a pipeline segment identified by the inspection system.The minorsegment is a section within the major segment where the nominal wall thickness isdistinctly different from that detected for the major segment.In the absence of information from the pipeline operator, the MAOP and Pi values for theminor segment will be assumed to be the same as those specified for the major segmentin which it is located.The nominal wall thickness within the minor segment will be estimated from readingsobtained from the inspection survey.The estimated nominal wall thickness will be eithera wall thickness stated by the pipeline operator as being present in the pipeline, or thenearest American Petroleum Institute (API) nominal wall thickness.The values of nwt, MAOP and Pi specified for each segment are used to calculate theERF value of each metal loss feature detected within the segment.A table listing the pipeline segments is presented

casings, dents, girth weld anomalies and repairs detected along the pipeline.Location reference points and changes in the nominal pipe wall thickness are also included inthe pipeline listing.There are four types of entry in the pipeline listing.These are:Girth WeldsEach girth weld entry consists of:- a girth weld number;- the relative distance along the pipeline to the girth weld from the previous(upstream) girth weld; and,- the absolute distance from the start of the pipeline.Metal Loss FeaturesEach entry for a metal loss feature consists of:- the relative distance along the pipeline to the upstream edge of the metalloss feature from the previous (upstream) girth weld;- the absolute distance along the pipeline to the upstream edge of the metalloss feature;- ML to denote that the entry refers to a metal loss feature;- EXT or INT to denote whether the metal loss feature is on the external orinternal surface of the pipe.It should be noted that mid-wall metal lossfeatures would be classified as external;- the predicted peak depth of the metal loss feature;- the predicted axial length of the metal loss feature; and,- the orientation of the metal loss feature, as viewed in the direction of flow.- the calculated ERF value for the metal loss feature.- those metal loss features which have undergone detailed processing andanalysis are indicated by a *.This includes all features reported oninspection sheets.Please be aware that the ERF values in the Pipeline Listing are allocated to individualfeatures. In the case of future corrosion, increasing depth of individual corrosion featuresis not the only consideration. Individual features in close proximity may link togetherthrough low level corrosion leading to higher net ERF values.Pressure Based Pipeline Summary ReportC0001_20AIssue 1Page4-19Identified Manufacturing FaultsThe entry for an identified manufacturing fault is the same as that for a metal loss featurewith the following differences:- MFG (in place of ML) to denote that the entry refers to an identifiedmanufacturing fault; and,- there is no calculated ERF value for an identified manufacturing fault.Pipeline Anomalies and FittingsOther entries in the pipeline listing relate to pipeline fittings and pipeline anomalies.These entries consist of:- the relative distance along the pipeline to the fitting or anomaly relative fromthe previous (upstream) girth weld;- the absolute distance along the pipeline to the fitting or anomaly; and,- a comment describing the fitting or anomaly.It should be noted that where the orientation of a pipeline fitting has not been specifiedthen the fitting is centred on the 12-00 position.If a pipe spool contains fifty or more metal loss features (that is corrosion, gouging andmill/manufacturing faults) then a metal loss spool summary will be provided and these featureswill not be listed individually within the spool on the pipeline listingThe metal loss spool summary will consist of two entries, a metal loss summary entry and theentry for the worst metal loss feature within the spool.The metal loss summary entry will be placed on the line after the entry for the girth weld locatedat the upstream end of the spool.This entry will not have relative and absolute distances.Thecomment will be SUMMARY and the total number of metal loss features (corrosion, gougingand mill/manufacturing faults) within the spool will appear at the end of the line.The entry for the worst metal loss feature within the spool will be placed at the correct relativedistance with respect to the upstream girth weld and will be in the format described above.Thisfeature will be identified according to the selection rules specified in the Specification for thePipeline Inspection Report (Appendix F).It should be noted that the pipeline listing in PipeVision will provide an entry for each metal lossfeature detected along the pipeline and will not contain metal loss spool summaries.Pipeline ListingLaunch to ReceiveGirth WeldNumber Relative
