1.0 Introduction

ILIAnalyst automates the analysis and management of ILI information, allowing the user to quickly review the current or historically stored ILI data sets, apply pre-defined acceptance criteria, select anomalies for investigation, and create your excavation site documentation – all within a few hours from receiving the vendor report. ILIAnalyst also records all the operational information about a tool run, such as tool specifications, contact details, inspection dates, inspected locations, inspected locations with bad data, tool velocity, interaction and burst-pressure algorithms used, and the pipe tally. It also allows the user to complete calculations such as burst pressure calculations (B31G, modified B31G and RSTRENG), generate a list of critical anomalies based on defined acceptance criteria and enable excavation results to be inputted to produce “predicted-vs-actual” plots. For ease of interpretation, bold-faced text is used in this user guide to highlight a feature or a component of the software.

ILIAnalyst 2

2.0 Accessing the Database

This application utilizes MicrosoftTM ActiveX data objects (ADO1) for database operations.

Upon launching ILIAnalyst, for the first time, the user will need to enter the database information via the Details Button in Figure 1 below.

Figure 1: Details - Database Configuration.

3.0 ILIAnalyst – Application Options

Once logged into ILIAnalyst, the user can configure specific application behavior, such as to use Imperial or Metric units, that are saved to a config file on that specific computer. Every time ILIAnalyst is run on this computer these configuration settings are applied.

To enter the configuration window, select Tools – Application Options from the Main Menu toolbar.

Figure 5: Tools – Application Options

ILIAnalyst 6

The Application Options window appears with four configuration categories to choose from on the left.

Figure 6: Application Options

3.1 Application Options – Display Options

Under the Display Options category, figure 6 above, the user can do the following:

1. Select Units (Metric or Imperial) from drop down boxes. These are set to Imperial by default.

2. Select to Show Hierarchy in the Inspector tool of the application. 3. Select to Show Station Series in the Inspector tool of the application. 4. Select how to setup the results grid with Auto Best Fit, Show Record Count. 5. Select pipeline selector Show Name and Search Mode within the system hierarchy.

When you are finished with this setup, click Apply if any changes have been made.

3.2 Application Options - Behavior Options

Click Here to access the sub-categories and update the options on the right-hand side of the window.

ILIAnalyst 7

Figure 7: Behavior Options

1. Use projects and setup how they behave:

When this option is turned on, the application will allow users to have more than one tab open with a separate project in each tab, and each project can have its selections configured independently of the other open projects. Also it allows users to save their selections into a project file, and to retrieve those selections again by opening the project file.

When this option is turned off, the application will allow only a single open project and will not support the saving and loading of projects. This behavior is similar to older versions of the IRAS applications and may be more familiar to users of the older software.

This option is turned on by default.

2. When starting the application,

This option is applicable when the “Use Projects” option is turned on.

It is a drop-down list with the following possible actions to take when the application is started: o Start with a new, blank project open.

The application will open a new project. It’s as if the application had started without a project and the user had pressed the “New Project” button. This is the default selection.

o Start with the latest project open. The application will open the last project that was closed the last time that the application was run. It’s as if the application had started without a project and the user had pressed the “Open Project” button and selected the last project the user had open.

o Start with no project open. The application will not open any projects. If the map is supported and visible then the map will fill the whole application space. Otherwise, the application space will show blue.

ILIAnalyst 8

o Ask the user for a project to open.

The application will open the “Open Project” dialog. It’s as if the application had started without a project and the user had pressed the “Open Project” button.

3. When closing a project,

This option is applicable when the “Use Projects” option is turned on.

It is a drop-down list with the following possible actions to take when closing a project (including when the application is closing): o Ask the user whether to save selection changes.

If any changes have been made to the project selections, then the application will ask the user whether to save those changes or not. This is the default selection.

o Automatically save selection changes. The application will automatically save the current project selections.

o Automatically discard selection changes The application will simply close the project, ignoring any changes made to the project selections.

4. Assign Project Folder Location:

This option is applicable when the “Use Projects” option is turned on.

This is the default location for all project files. When loading or saving project files, the user can navigate to other folders, but the open file and save file dialogs will open to this folder first.

The default location is “My Documents\Dynamic Risk Assessment Systems\Projects\”.

5. On application startup, load previous selections

If the “Use Projects” option is turned off, whenever the application closes, the current selections are stored for later use. If this option is turned on, then when the application starts it restores the settings from the previous session.

If the “Use Projects” option is turned on, whenever a project is opened, saved, or closed, its selections are stored for later use. If this option is turned on, then when a new, blank project is opened, the application applies the settings that were saved previously to the new project.

If the “When starting the application” option is set to “Start with a new, blank project open”, the application applies the settings that were saved previously to the new project.

This option is turned on by default.

ILIAnalyst 9

6. Ask for confirmation when closing the application

If this option is turned on, then when the application is closed, a message dialog appears asking “Are you sure you wish to exit the application?”

This option is turned on by default.

7. Show instructions when opening a new project

All application projects include a set of basic instructions for getting started. If this option is turned on, then new projects will automatically display the project instructions.

This option is turned on by default.

The project instructions form has a check-box where the user can choose to turn off this option.

8. Embed instructions in a project window

The project instructions are normally shown in a pop-up window that appears in front of the application.

If this option is turned on, then the project instructions will appear in a panel that is part of the project window.

This option is turned off by default.

9. Warn when the pipeline selection is changed while the project contains data.

Most IRAS applications require the user to select one or more pipelines from the hierarchy selector and then run a query to retrieve data based on that selection. When the hierarchy selection is changed by the user after querying the data, the data is then invalid and is cleared from the project.

If this option is turned on, then when the hierarchy selection is changed, a message dialog appears warning “Changing the project selection will clear the project data” and asking “Do you want to continue?”

If this option is turned off, then the data is cleared without warning.

This option is turned on by default.

When you are finished with this setup, click Apply if any changes have been made.

There are several zoom options in the toolbars that allow the user to focus on a specific area of the data being displayed. There are two sets of independent toolbars, one for the ILI Data Band and the other for the ILI charts. Therefore the zoom level and focus area can be adjusted to analyze these datasets independently. All of the Centerline charts are synchronized by chainage so that they display information for the same chainage range. An option called Sync Zoom can be used to synchronize the chainage ranges displayed in the Data Band and the ILI charts.

5.0 Project Inspector Pane

The Project Inspector Pane is made up of three parts: the System Hierarchy, ILI Runs, and buttons to access the analysis tools.

5.1 System Hierarchy

In order to retrieve and display data for a specific location, the user must create a data request from the System Hierarchy Selection window shown in Figure 16 below. The top half of the window controls are used to specify the Query Location that describes the start and end location of the area of interest. The bottom half of the pane contains a menu of the data series that are available for display.

ILIAnalyst 26

Before the user can begin to display any data in ILIAnalyst, they must first establish their query criteria. An integral part of the criteria is the Query Location, which will define the start and end limits for the location of interest on the pipeline.

1) The first step is to find the first selectable level within the System Hierarchy Selection Window. This can be performed by:

a. Clicking on the (+) (-) will expand/compress the different pipeline hierarchy levels

located within the pipeline system. The user can use this method to find the appropriate Hierarchy level to query (i.e. Discharge System or MLV Section).

b. Click on the Expand to First Selectable Level button located within the

Hierarchy Selection Window. This will expand the Hierarchy tree to the first available query level within the Pipeline System. From here the user can further drill down by clicking on the (+) icon.

2) If the user knows the name or part of the name, of the system they wish to query, they can type part or the entire name within the search window and hit Enter on their keyboard. The search feature will navigate the user to the first match found. To keep searching the tree, simply select the Search Next button. Once the search feature has reached the end of the Hierarchy tree, or if the query cannot be found, the user will receive a message window informing them of this.

3) Once the user has located the section for their query, they simply click inside the

corresponding check box until they see a check mark.

4) To reduce the clutter that can occur in the System Hierarchy Selection Window, once a selection has been made, click on the Expand to Selected Nodes button. If you wish to expand the entire Hierarchy tree, simply click on Expand All.

5.2 ILI Runs

Once the query location has been selected, the ILI Runs window will populate with all ILI runs that have been aligned to the query location from the IRAS database.

Figure 21: ILI Runs window

ILI runs aligned with the selection made in the System Hierarchy will appear here.

ILIAnalyst 27

5.3 Analysis Tools

There are 13 analysis tools used to analyze an ILI dataset. They are located underneath the ILI Runs. The analysis tools and their functions are summarized in the following table. Table 3: Analysis Tool Buttons

6.1.1 Display

Figure 23: ILI Data Pane

This chart is used to display the orientation, location of each defect, pressure and inspection range on the pipeline. The start and end positions of the inspection range are displayed by a green line at the beginning and end of the chart. Each button in the color scale has a range (between two values) for the Peak Depth Percent (PDP) or Rupture Pressure Ratio (RPR) associated with it. The third drop-down option is Anomaly Response. Anomaly Response is the results of Liquids 195.452 or Gas 193.233 rule sentencing performed by the Chainage Alignment Tool. The Box Color option is used to switch between the three plot types (display PDP or by RPR or by Anomaly Response). For example, in a RPR plot, as shown in Figure 18 above, the yellow button has an upper value of 1 and a lower value of 0.72. A defect appearing in yellow corresponds to a RPR value between the two values. The values in the color scale have been predetermined but can be changed manually by clicking on the ILI Option button. Detailed configurations of these values are discussed under Display Options. Inactive anomalies are always represented by a gray color in the legend.

Figure 43: Metal Loss Type Plot Tool Chart

The Metal Loss Type Plot tool is used to plot cluster data by anomaly type. The chart is divided into areas by corrosion type based on the dimensions of the anomaly. These areas are labeled to identify the type of anomaly. A unique color is assigned to each anomaly type that corresponds to the colored boxes, located in the Display Legend Panel. The text field next to each color box displays the total number of anomalies by type. The following list shows the types of anomalies that may be present:

- Inactive - Pinhole - Pitting - General - Axial Pitting - Axial Slotting - Axial Grooving - Circumferential Pitting - Circumferential Slotting - Circumferential Grooving

The Display Controls Panel exhibits an anomaly count and is broken down by surface type and metal loss type. The width and length of each cluster can be determined by its position on the chart.

For example, the cluster as shown in the chart has an approximate width of 52 cm and a length of 35 cm and is categorized as General.

18.0 Sentencing Plot

Figure 50: Sentencing Plot Tool Chart

The Sentencing Plot tool can be used to determine if clusters satisfy or fail to meet the acceptance criteria defined by the user. As shown in Figure 48, the clusters’ depth percentage and length are plotted with the acceptance line(s). Each acceptance line is plotted according to the user defined acceptance criteria and pipe attributes combination (i.e. NPS, WT, Grade and MOP). If clusters do not meet the acceptance criteria, they will appear above the acceptance line in the chart. Under the ILI Charts Menu Toolbar, the Acceptance Criteria option can be changed by selecting from the drop-down menu. The drop-down list box allows the user to define the acceptance criterion by RPR or MOP x the value entered (MOP*). The default setting for the PDP is 80 % and cannot be changed. The ILI dataset may contain pipe data with distinct combinations of nominal pipe size, wall thickness, grade and MOP. An acceptance line is plotted for each combination, and the details are outlined in the Sentencing Plot Legend on the right hand side of the screen. The colored buttons in this panel are active buttons and can be turned on and off simply by clicking on them. To unselect an option, click on the button and the corresponding Acceptance line will disappear. Click the button again to bring the line back. The acceptance criteria and the selected pipe attributes combination will determine the plot of the acceptance line and therefore determine the severe anomalies.

21.0 Unity Plot

Figure 59: Unit Plot Tool Chart

The Unity Chart tool allows the user to perform POE (Probability of Exceedance) analysis, by supplying a statistical distribution of the ILI tool accuracy (predicted vs. actual). This distribution derived from these data points serves to characterize the measured size of the anomaly compared to the size as reported by the ILI tool. A confidence interval can also be applied to showcase whether the ILI tool calls are dominantly conservative, non-conservative or within specification. Typically, a tool’s accuracy for detecting corrosion depth will be at 80% of their calls within +/- 10% of the depth. There are four chart parameters for the user to set and they are marked as Chart criteria in the picture above.

31.0 APPENDIX A

Frequently Used Features

This section describes the features in ILIAnalyst that may be available in an analysis tools. These features allow the user to view or scroll through the data in a table or chart.

31.1 Zoom/Pan

Under the Zoom/Pan option group there are two options that control how the information in the chart is viewed when panning or zooming: 1) Horizontal Only or 2) 2D. The Horizontal Only option allows the user to move through information in the chart in the horizontal direction only when panning. Similarly, when zooming, only the horizontal axis will change and vertical axis will remain the same. The 2D option allows the user to pan in both the vertical and horizontal directions; thus the view in the chart will change in both directions.

31.2 Using the Magnifying Glass Zoom

Zoom In Magnifies the chart, increasing the resolution each time you click on the button.

Zoom Out Shrinks the chart, decreasing the resolution each time you click on the button.

31.3 Window Zooming

. Window Zoom - zooms to a specific location on a chart by dragging a rectangular area in any chart from the top left corner to the bottom right corner. The center of the dragged rectangle becomes the new display center, and the area inside the dragged rectangle is enlarged to fill the display area. Dragging a rectangle in the opposite direction from the bottom right to the top left will zoom out to display all of the data within the chart.

ILIAnalyst 78

31.4 Panning

To pan through the chart, click and hold down the secondary mouse button. Then drag to a desired location; this will not change the size of the chart but only the position.

31.5 Using Scroll Bars

When there are more choices or information that can fit in a list box or window, scroll bars are used to view through the items or information. To scroll through information displayed:

1. Drag the horizontal scroll box to scroll through all the information left or right. 2. Drag the vertical scroll box to scroll through all the information up or down.

The following techniques can be used to scroll: Table 9: Scrolling Techniques

31.6 Map Options

In Map Options the user can customize the output. To access the Map Options dialog box, click

on the button within the Map toolbar ( ).

31.6.1 Map Information

This information window lets the user know whether they are using ESRI Map Objects or ARCGIS to display the map.

Figure 73: Map Information (MapObjects) Figure 74: Map Information (ARCGIS)

The options available for Behavior, Colors and Contours differ according to the Map Information being displayed. In version 4.3 applications the map uses a reference to an .mxd file it copies from the database to your local computer. Web Imagery and Specific imagery path locations are built by the Dynamic Risk team into the map that is then loaded into the IRAS database. As a result, we removed the Web Imagery, ARCSDE, and image path location setup windows as these are no longer utilized.

Map Refresh Delay – Allows the user to select a delay for the map progress bas in milli-seconds. A progress bar is displayed when the map is redrawing. For long updates is is helpful to know when the update is finished. For short updates it can de distracting. A delay can hide the progress bar for most of the short updates, but may appear to be unresponsive for longer updates if the delay is too long. We suggest leaving the default of 100 ms.
