3 1 Introduction The purpose of the is to facilitate the alignment of inline inspection (ILI) data to stationed IRAS pipeline and appurtenance data. This manual contains instructions on how to use the to align ILI data into the IRAS database. For ease of interpretation, boldfaced text in this manual is used to highlight an option or a component of the software. The may also be referred to as CAT throughout the manual. 2 Accessing the Database Upon launching CAT, for the first time, the Login Screen (Figure 1 below) will prompt you to enter the name of the server and the name of the database. Select the Details Button on the Login Screen to access the Connection Details page (Figure 2 below), in order to enter the connection information. Figure 1: SQL Server Login Screen The first time CAT is used, the Login screen will not contain any information. The next time the application is used the previous successful login information will be filled in. All you will need to do is click on the OK button to access the application. 1

4 2.1 SQL Server Login to Access the Database If you are connecting to a SQL Server database select SQL Server from the DBMS dropdown list. Then enter the name of the Server and the Database name you wish to connect to. Use the Test Connection button to verify that your login settings can actually talk to the database. Figure 2: SQL Server Connection Details Window 2

5 2.2 Oracle Login to Access the Database If you are using Oracle configuration, then use the Native Provider from the Oracle provider drop down box (this is the default setting). Enter the oracle server name along with your Username and Password. Enable the option Remember Password so that the application will remember the password the next time you login. Figure 3: Oracle Connection Details Window 2.3 Login In Click Test Connection and once the database connection has successfully passed then click on the OK button. If your test is unsuccessful or if you are not sure what your database settings are, check with your Database Administrator (DBA). NOTE: If you type in the wrong connection simply click the New Connection button to start over. In this screen, if you wish to exit CAT, one of the following can be done: 1. Click on the Cancel button 2. Press Alt+F4. 3

28 4 Importing ILI Datasets Before beginning the import process, you must first select which line the data will be applied to by navigating the tree in the System Hierarchy pane, see Figure 37 below. Once a line has been selected you are able to Import the ILI data set to be aligned. Figure 37: System Hierarchy Pane 4.1 Inline Inspection Import - Detect DRAS Spec Version The CAT tool has the ability to detect the DRAS ILI Specifications of an import file for ILI runs. Currently CAT can detect spec versions 4.4, 4.5 and 4.6. Begin the import process, of your Inline Inspection run, by Clicking on Text Import ( ) icon. A pop-up window will appear as shown in Figure 38 below. This window allows you to navigate to the spec file you would like to import and then to detect the version of the spec file. 26

29 Figure 38: Locate Text File Select the ellipses ( ) icon in the file location selection box. This will open a folder browser window. Figure 39: Folder Browser Navigate to your ILI files folder location and select OK. The folder browser window will close and return you to the specification detection window with the Location of Files path populated. Click on the Detect button and CAT will detect the version of the files and show you the spec version within the Results box. Figure 40: Spec File Detection 27

30 If there are errors CAT will report them within the Results box. CAT can detect if spec files are missing, as in Figure 41 below, and if there are extra or missing columns, as in Figure 42 below. Errors encountered must be fixed in the spec files before proceeding with the import process. Figure 41: Spec File Detection Error Missing Files Figure 42: Spec File Detection Error Missing Columns If you would like to load the files as reversed, select the corresponding checkbox in the lower left of this window. If you have no errors, as in Figure 40, click the OK button to start the load process. 28

31 4.2 Inline Inspection Import: Validation Process When importing spec files, the first thing the CAT application does is to validate the files to ensure they are in the proper format to load into the IRAS Database. Validation errors are reported in this step. Figure 43: Spec 4.6 Version 1. Ensure the Location of Files field contains the path to your ILI text files. 2. Click on Check Files. To validate the text files within the ILI Run. 3. Once the files pass validation Click the Next button to continue. Note: Unpin the hierarchy pane allowing it to slide to the side giving you a full ILI Data Pane to work with. If a validation check fails, you will be presented with an error message dialog box, which may contain a summary of the errors. Select OK or close ( ) the box to continue. Also, notice that the file validation results will place a red X on the Text file tabs that contain errors. You must refer to the DRAS ILI Specification document to ensure that the noted file and data conform to the specifications. Note: The failed exceptions must be corrected within each failed text file before the data can be imported. Corrections cannot be made using the CAT tool. Every time the Check Files button is clicked, CAT will perform the validation check again. If you wish to exit the program at this time, you may do so by clicking on the Cancel button. 29

32 Validation error rows in the Inline Inspection file will be highlighted in red Figure 44: Import files Window validation failed If a file validation check fails in the Joint, Facilities, Other Anomalies, Call Box or Crack Anomalies files, along with the red X on the file, error columns will be highlighted in red and there will be a message icon ( ) within the corresponding message field, see Figure 45 below. Select the icon to display the error message. Note: This version of CAT displays only error rows during the validation process, where the previous version displayed all the data including errors. Figure 45: Import files Window validation failed Note: When all the file tabs indicate that they have passed validation it is a good idea to do a visual check to ensure there are no records in the tabs. Once the validation process passes, click Next to continue to the import process. 30

33 4.3 Inline Inspection Import: Dictionary This step of the import process allows you to match the anomaly statuses found in the spec files with the associated statuses found in the CAT Status Dictionary. Simply go through all the anomaly tabs and for each vendor Status found and check that the associated Status matches. If the statuses don t match, select the correct status from the associated drop-down list box. Figure 46: Import Status Dictionary You can assign the same status to several rows at a time by multi-selecting the rows and then using the Status drop-down list box found on the Inline Inspection Import grid menu bar. Figure 47: Import Status Other Anomalies Once all matches are complete, select Next to continue the import process. 31

34 4.4 Inline Inspection Import: Inspection Information In this step of the import process you can do the following: 1. Edit the Inline Inspection Name for this run. 2. Edit the Inline Inspection Description for this run. 3. Match the pertinent data within the InlineInspection.txt file with values defined by the within the database. a. The defined values are found on the left side of this panel. These values can be changed by selecting an item from the associated drop-down list box. 4. Inspection in Reversed Direction: This is a non-editable field that indicates if the Inline Inspection run was loaded in Reversed Direction. Figure 48: Inline Inspection Import Inspection Information Note: Field names on this screen written in Bold text indicate required data fields. You must enter or select a value for each of these fields before proceeding to the next step. Once all required information has been filled in on this screen click the Import ( ) button to continue with the import process. Once the import process is complete you will be presented with a dialog box showing the status of the import. Figure 49: Promotion Status Select the OK button to finish the import process. 32

35 5 Aligning ILI Datasets Before beginning the alignment process, you must first find the imported dataset to be aligned and its location on the pipeline. The Vendor ILI Data Selection Pane and the IRAS System Hierarchy Pane are used to define this information. Figure 50: ILI Run Selection 5.1 Selecting an ILI Run to Align 1) From the IRAS System Hierarchy pane identify the pipeline you would like to align this dataset to by: a. Selecting Expand All ( ) in the System Hierarchy Toolbar to expand the System Hierarchy in the Selections window down to the valve section, or b. Select Expand to Selected Nodes ( ) to display any selection that has already been toggled and to collapse the rest of the tree, or 33

36 c. Select Expand to First Selectable Level ( )to expand the tree to the first level you can choose from, or d. You can also enter in any combination of letters and numbers to identify the Pipeline Index in the Search Input Box. As you type in the Search Input Box the Hierarchy will jump to and highlight the first instance of a match to your input. You can continue searching for more matches to your input by clicking on the magnifying glass Search Next ( meeting your search criteria. ) icon or use F3 to search for more data e. When you have found the node you want, click the associated checkbox to its right. 2) Once a node has been selected from the IRAS System Hierarchy Pane, the Vendor ILI Data Selection Pane will populate with all associated ILI runs that have been imported. In the Vendor ILI Data Selection Pane select the ILI run you wish to align the selected pipeline segment to, as shown in Figure 50 above. The Status of an ILI run is a great tool to finding the run that was just imported. Each status is explained below. Loaded The ILI Run text files have been loaded but the ILI Run has not been aligned. Processed The ILI Run has been imported, aligned, and loaded into the IRAS database. Updated - This ILI Run has been Updated since the initial load to the database. Locked This ILI Run is in the process of being aligned by another user. 34

37 Figure 51: ILI Details More information on the surveys can be found on the Details tab, as shown in Figure 51 above. Note: The ReversedOrder checkbox on the Details tab of a survey provides an indicator of the direction the survey was loaded in. 3) Select the Align button from the Shortcut Icon Toolbar, or select Tools from the main menu toolbar and then Align, or simply press F9 to continue to the next step. 35

38 Figure 52: Align 36

39 5.1.1 Align Jump to The Alignment tool wizard allows you to take a run that has previously been loaded and to follow every step of the alignment process to the end, sentencing the run. You may, however wish to take a loaded run that did not pass through all the alignment or sentencing steps and Jump to the alignment step or to Jump to the sentencing step of the wizard. Figure 53: Jump to Note: You will be re-directed to the Dictionary step if you attempt to jump to alignment or sentencing without having completed and saved the dictionary Notable Exceptions Report If the ILI Run has previously been aligned, the associated Export Notable Exceptions to Excel button ( ), found in the rightmost column of the Vendor ILI Data Selection Pane, will be enabled, see Figure 51 above. Clicking this button will generate the notable exceptions report in Excel format containing matched and unmatched information. Figure 54: Excel Notable Exceptions Reports Note: The Notable Exceptions report is generated using the units based on the system of measure that was specified in the text files while importing data. 37

40 5.2 Inline Inspection Alignment: Dictionary In this step of the alignment process, the software filters the dataset for entries that are associated with the imported Inline Inspection. Listings of the unique entries from the dataset selected are presented within the Facilities, Corrosion Features, Other Features and Crack Anomalies tabs. 1) Match the vendor description with the type from the drop-down list located at the end of each row of data. The drop-down list is populated from the corresponding tables in the IRAS database. The matching must be performed on every type displayed under the Facilities, Corrosion Features, Other Features, and Crack Anomalies tabs located at this step. 2) Only when all matches have been completed will you be able to click Next. This process defines the dictionary for possible control points, which can be used for aligning the stationed IRAS pipeline centerline to the vendor data. Note: If no entries are defined, no control points can be created. Figure 55: Dictionary: Matching 38

41 If you have more than one record to update, follow these steps: 1. Select the similar types to update all together as one type (this will highlight them as in Figure 57 below). a. Hold down the CTRL key on the keyboard and click on each record row you would like to select. These rows will highlight, or b. Select the first row to edit by clicking on it to highlight then hold down the Shift key on the keyboard and click on the last record to highlight. 2. Select the match type from the Facility Type drop-down selection list that you would like to update the selected records to. Figure 56: Selecting Multiple Records to Update 39

42 3. Click on the Update Selected Rows ( ) button. Figure 57: Matching multiple records 4. Once matches have been made across the different tabs, click the Save button to continue. If everything has been matched and saved, the Next button will become enabled. Click Next to continue. 40

43 5.3 Inline Inspection Alignment: Alignment In this step of the Alignment process you can choose to do manual or automatic (application driven) matches. These matching processes create control points that will be used to align the dataset to the IRAS pipeline centerline. There are three sections to this screen: - Base: Lists entries from the IRAS database - Current ILI Control Points (Vendor Data): Lists data from the source data (vendor text files) - Chainage Difference Chart: Shows the cumulative difference of the control points, which is the match between the vendor data and the IRAS data. It is the DBChainage subtracted from the Odometer column. Matched control points are highlighted by colors denoting their match type. Select the Show Legend button ( ) on the alignment grid menu bar to display the Match Type Legend Colors popup window for your reference, see Figure 58 below. Figure 58: Match Type Legend Colors 41

44 5.3.1 Base (IRAS Data - left side) This data grid lists entries from the IRAS database. The control points that are used to align and load the dataset are shown highlighted in blue below on the grid. Control points located within the IRAS Database such as Valves and Markers can be selected from the grid and will be highlighted on the map by a circle in the color currently selected for the for the Grid Row Extent, if the grid row extent button is selected on the map as shown in the example below, Figure 59. Figure 59: Matching IRAS Control Points to Vendor ILI Data 42

45 5.3.2 Current ILI Control Points (Vendor Data - right side) This data grid lists the entries in the source data. Entries matched with IRAS Data entries create control points. The control points that are used to align and load the dataset are shown highlighted in blue in Figure 59 above Manual Control Point Assignment This step is for manually creating as many control points as possible between the two lists. I. To create a control point, click on and drag an entry from the Base (IRAS Data) grid and drop it on top of the corresponding entry in the Current ILI Control Points (Vendor Data) grid. A green highlight is used if the entry is the most likely match. A yellow highlight will be used if the entry is a possible match, but less likely than the items in green. Matched data used to define control points can only be made with either green or yellow highlighted rows. Figure 60: Color codes when matching IRAS Control Points to Vendor ILI Data The matched entries defining control points are shown in blue, as seen in Figure 61 below. You can delete a control point by selecting it and right-clicking the Clear this Match button. The entries on both sides will then be colored white. Figure 61: Matched IRAS Control Points to Vendor ILI Data 43

46 5.3.4 Automatic Control Point Assignment Three options are available for Auto-alignment: Spatial Alignment Girth Weld Length Match Girth Weld Number Match Figure 62: Automatic Control Point Assignment Note: When using the Girth Weld Match processes, you can exclude unmatched entries from the matching process. To do so, right click on an un-highlighted entry and select Ignore this Control Point. Figure 63: Ignore Control Point An Ignored entry can be re-activated by right clicking on the entry and selecting Activate this Control Point Spatial Alignment Running Spatial Alignment Select Spatial Alignment from the Automation drop-down list on the Inline Inspection Alignment menu bar. 44

47 Figure 64: Spatial Alignment Note: Spatial Alignment can only be run on the Centerline Control Points. As a result the Spatial Alignment option in the Automation drop-down list is deactivated when a base run other than Centerline Control Points is selected. Another requirement for using the spatial alignment feature is that ILI vendor files must contain spatial data (Latitude and Longitude values), as shown in the Excel view of a Joint text file in Figure 65 below. Figure 65: Spatial Data Excel View of Joint Text File If the ILI vendor files don t contain spatial data you will be given a warning, as shown in Figure 66 below. Figure 66: No Spatial Data Warning When you select OK the warning will close and the application will not proceed to Spatial Alignment. 45

48 If the ILI vendor files contain spatial data, you will be given a warning that using geographic location for alignment will clear all existing alignment that may have been done to this survey. Select Yes to continue and the Geolocation threshold option will appear. Figure 67: Spatial Data Alignment Warning Before you perform a Spatial Alignment you must set the Geolocation Threshold Figure 68: Geolocation threshold Enter the maximum distance from the line to which a feature will be matched. In Figure 68 above, ILI points that are more than ft. from the centerline will not be matched. Click OK to close the Geolocation threshold window and start the auto-matching process. Figure 69: Projecting Latitude/Longitude to the line progress bar 46

49 When the process has completed the Current ILI Control Points grid view will change and display a summary of the results as we see in Figure 70 below. Figure 70: Spatially Matched Run Entering Chainage In Figure 71, notice that there are a couple of unmatched records (white rows) at the beginning of the run. In order to ensure that these records (features) are included in the alignment you need to enter a DB Chainage for the first record. Right Click on the first joint in the Current ILI Control Points grid and select Enter Chainage. Figure 71: Enter Chainage 47

50 The DB Chainage input dialog will open. Figure 72: DB Chainage at Start of run Enter the DB Chainage found for the first matched point (0.0). If there are unmatched points at the end of the run, enter the DB Chainage for last unmatched point of the run. Figure 73: DB Chainage Entered for Unmatched Point The row will become highlighted in green when chainage has been entered. Select Next to continue to the next step of the alignment process The Offset Chart When Spatial Alignment is used the Difference Chart is replaced by the Offset Chart, see Figure 73 above. The Offset Chart displays a representation of the distance between projected ILI coordinates of a feature and the Centerline. Figure 74: Offset 48

51 The Offset Grid Value The Current ILI Control Points grid for spatially aligned runs contains an Offset column on the right side of the grid. Figure 75: Spatial Matching - Offset Note: The data displayed in the Offset Column is the difference between lat and long control points, laterally to the centerline, that have been matched during the spatial alignment. Interpreting Offset Values: White rows are unmatched records. Offsets can t be determined for these records. One possible reason is that they may not contain spatial data. Blue highlighted records that have an Offset of 0 indicate an exact match. Blue highlighted records that have an Offset greater than 0.00 indicate the match between the ILI data and the database are not exact, but they do fall within the Geolocation Threshold criteria and so they are matched. Red highlighted records are ILI points that fall outside of the Geolocation Threshold ( ft) that was set in Figure 68 on page

52 Girth Weld Match CAT Alignment has the ability to match two ILI runs that have been done on the same pipeline, by comparing girth weld lengths found within the two runs. The user can align the ILI run with the master girthweld table now To start, select a previous ILI run from the Base (IRAS Data) drop-down list of runs as shown in Figure 76 below. Figure 76: Base ILI Runs List Adjust the Girth Weld Match Tolerance before running Girth Weld Match. See the Girth Weld Match Tolerance section below. When the Base Control Points grid has completed loading the previous ILI run you have selected, you can run the Girth Weld Match algorithm. Select Girth Weld Match from the Automation drop-down list on the Inline Inspection Alignment menu bar, see Figure 77 below. Note: The Girth Weld Match option is only enabled if you have chosen a previously aligned Base run to align to. 50

53 Figure 77: Girth Weld Length Match Running Algorithm The algorithm will run and the resulting matching will be displayed in the grids, see Figure 78 below. Figure 78: Girth Weld Match - Matching by Algorithm Algorithm matched control points will be highlighted in blue. You can now continue to refine the matching by: Manually matching control points that were not matched by the algorithm. Clearing some matched points and selecting better match points manually. Clearing some matched points, adding manually matched points and then re-running the algorithm. WARNING: Using a mix of Manual and Automated matching can result in undesirable behavior in the automated matching algorithms that can lead to an infinite algorithm evaluation cycle. We recommend that manual matching be used after any automation. Prior to executing an automation, all manual matches should be cleared. 51

54 Manually matched control points are highlighted in dark blue Figure 79: Manual Match You can clear individual match points by right clicking on the match point and selecting Clear this Match. Figure 80: Clear This Match You can clear several match points at a time by multi-selecting them and right clicking on one of them and selecting Clear these Matches. Figure 81: Clear These Matches 52

55 Girth Weld Match Tolerance The Girth Weld Match Tolerance ( ) button is added to the Inline Inspection Alignment menu bar next to the Automation drop-down list, when a previous ILI run is selected as the Base run. The Girth Weld Match Tolerance input window allows you to enter a tolerance length within which two joints from different runs can be considered the same (matched) joint. Increasing tolerances will result with more matches, but they will be less precise. Figure 82: Girth Weld Match Tolerance The GirthWeld Matching is performed in 2 phases. 1. The algorithm is looking first for the shortest segments of the pipe. The search for these pipeline segments is using the tolerance from the lower drop down list of numbers. In the image above, it is 1.5 ft. When 2 short pipe segments are found with their length difference less than 1.5 ft, the algorithm searches for the next short pipe segment match. 2. Once the matching 2 sets of short pipe segments are found, the algorithm will search for the matching pipe segments between the two short pipe segments. This time, much lower tolerance i.e. 0.4 ft is being used, to guarantee good match of the pipe segment sequences. The values 0.4 ft and 1.5 ft are the defaults. These numbers are also unit-less, and are used only for the girth weld searches. The table below illustrates the phases of the algorithm. The pipe segments highlighted in yellow and orange, represent 2 matching pipe segments found in two different ILI runs. These segments were matched with the tolerance of 1.5 ft. The pipe line segments between the matched yellow and orange segments are going to be compared with the tolerance of 0.4 ft. The green and blue arrows show direction of the search and pipeline segments lengths comparisons. 53

56 Table 1: Two ILI runs are being compared for the length of their respective pipeline segments. 54

57 Chainage Difference Chart This chart illustrates the running difference between the reference distances contained in the dataset, relative to the stationed pipeline distance, based upon the control points defined. Each control point defined is plotted as a point in the chart. For clarity, the database chainage is displayed when aligning ILI data. Figure 83: Chainage Difference Chart This chart can also be synched to the map and associated control point for more detailed analysis. Figure 84: Chainage Difference Chart Synched The goal when defining control points is to generate a smooth continuous graph. This would be representative of an accurate alignment where ILI tool wheel slippage occurs in a uniform manner. Sharp spikes in the graph may suggest inconsistencies between entries in the data set and the IRAS database or incorrect matches for a control point. You can review each control point as it is defined to assess the quality of a control point with respect to the others.

59 Matching Screen and Chainage Difference Chart Controls Figure 85: Alignment Grid Menu Bar There are two sets of data that can be exported here: Database control points in the following formats (Excel, XML, HTML, and Text) Source control points in the following formats (Excel, XML, HTML, and Text) Three options are available for Auto-alignment: Spatial Alignment Girth Weld Match (By Length) Girth Weld Number Match Allows for the setting of the Girth Weld Match Length Tolerance. This will clear all the match points. You will be prompted before clearing all control points. There are two choices listed in the drop down menu: Clear Spatial Mathes and Clear GirthWeld Matches. The checkboxes will allow you to filter both the Vendor and IRAS grids for specific match types of points. In this example, you will be able to see all the information from both Vendor and IRAS grids. Uncheck all boxes except for Valve to only view valves, and repeat process to only view Casing or Markers. The filter checkboxes are arranged so that the most obvious type of match points begins on the left side. Thus, it will be more effective if you filter and match the match point type from left to right. Synch Zoom, synchronizes the map to the current selected match point. Enables or disables the automatic scroll on the pane for positioning of ILI control points, after selecting a Database Control Point to match. When enabled this will find the nearest record by chainage in the Current ILI Control Points grid. This will work on matched runs where chainage is available. 57

62 5.4 Inline Inspection Alignment: Exceptions Report This step allows you to view the Notable Exceptions found in the ILI run. The initial view of this page does not show the match exception. Figure 89: Inline Inspection Alignment - Exceptions Report You may view the match exceptions by selecting the Show Notable Exceptions button ( ) on the Inline Inspection Alignment menu bar. The exceptions are broken down in the following tabular information: 1) Unmatched Benchmarks a list showing benchmarks within the IRAS database and Vendor files that remain un-matched. 2) Unmatched Appurtenances a list showing appurtenances within the IRAS database and Vendor files that remain un-matched. 3) Unmatched Casings a list showing casings within the IRAS database and Vendor files that remain un-matched. 4) Unmatched Sleeves a list showing sleeves within the IRAS database and Vendor files that remain un-matched. 5) Unmatched Valves a list showing valves within the IRAS database and Vendor files that remain un-matched. 6) Pipeline Material Mismatch - a list of the pipeline material that doesn t match up between the IRAS database and vendor files, however the data is still loadable. Note: A FAILED remark in the Show Notable Exceptions screen indicates that some records in the dataset were not used in the matching process, but you can still proceed. 60

Once you have reviewed the match exceptions and decided that the notable exceptions are acceptable, click Next. 5.5 Inline Inspection Alignment: Range With the range selection screen you must specify a range for the ILI run. A range marks the start and end locations where data was collected for the ILI dataset. Locations outside of the ranges define non surveyed locations or gaps in the survey along the pipeline route. The Range is defined based on known control points, and can be marked by start data and end data points. 61

64 Figure 91: Range Screen To create a new range click on the Add Range ( required fields. ) button, then proceed to fill in the Figure 92: Range Screen Definition of Range At this point you must enter a description for the ILI range as well as the start and end odometer. The start and end odometer fields can be filled in by dragging and dropping from the selection list on the top of the Matched Points panel. Drag and drop a valid control points into the Start Odometer and End Odometer fields. In addition, the start and end odometers can be automatically assigned as the first and last matched points by clicking on the Use 1 st and last matched points button. When finished select the Done button in the Range Description section to create the range. The Range description will be visible in ILIAnalyst. 62

65 Figure 93: Range has been defined You can remove an existing range by selecting the particular range and clicking on the Delete Range ( ) button. You can synch the range to the map using the Synch Zoom button ( ) At any time Match Point and Range data can be exported in the following formats (Excel, XML, HTML and Text). To do this select the Export button and then Matched Points or Ranges. Figure 94: Export Matched Points/Ranges Once the range has been created, you may then proceed by clicking the Next button at the bottom of the window. By clicking the Next button, you agree to continue with updating the database with the new control points and the range information created. If you decide to update the database at a later time, you can simply select save and close the application, without making any changes to the database. 63

66 Note: At any point during the entire alignment process, you can click on the Save button to save completed work and close the application. 5.6 Inline Inspection Alignment: Sentencing Use the Sentencing selection box to choose what anomaly sentencing rule you wish to perform on this data. If you do not wish to use any rules you can select No sentencing from the category dropdown list and select Next to continue to the next step in the alignment process. The default sentencing categories available are US P Section H (2004) for liquids and 49 CFR for gas. Note: The sentencing rules available to you are dependent on your configuration. You may have a set of rules specific to your company. You may also not have or implemented. Figure 95: Sentencing Options US P Section H (2004) Sentencing The Categories matched to the control points during this step will be dependent on the grading Regulation selected from the Sentencing drop-down list.
