# PL Survey

> [!NOTE]
> Take note
> 
> This overview will explain how to use and interpret the data in the IMS PLSS PL Survey module.

The IMS PLSS PL Survey Module is a tool that allows you to enter and manage your Depth of Cover (DoC) data for Buried Pipelines ensuring they are adequately covered to prevent external corrosion and other forms. To access this module, navigate to the Equipment Details page for Pipeline, Flowline, or Pipeline Jumper Equipment groups and click the Survey button in the header.

## Depth of Cover

The Depth of Cover section consists of **By DOC ID** and **By Location** tabs on the left and a graph on the right. The two tabs allow you to view and input Depth of Cover data organized by either DOC ID or Location. The graph provides a visual representation of depth measurements compared to design specifications.

### By DOC ID

The first tab, **By DOC ID,** allows you to input and view the Depth of Cover data. This tab includes the following information:

| Column Name | Description |
| --- | --- |
| Survey date | The date of the Survey where the Depth of Cover was measured |
| DOC ID | The ID of the Inspection Location where the Depth of Cover was measured. |
| Location | The location on the Pipeline where the depth of Cover was measured. |
| Design DOC | The Depth of Cover at which the Pipeline Section was installed. |
| Measured | The Measured Depth of Cover. |
| Difference | The difference between the measured Depth of Cover and the Design DOC. |

Doc Data in the By DOC ID tab.

### By Location

The **By Location** tab displays the same data as the **By DOC ID** tab, listing the depth of Cover information by Location i.e. Kilometer Point (KP) instead of by DOC ID.

Doc Data in the By Location tab.

### Graph

The accompanying graph dynamically adjusts based on the selected tab. It provides a visual comparison between the measured Depth of Cover values from various Survey Dates and the original Design DOC values.

## Adding Dept of Cover Data

To add the DoC into the Survey module you will need to:

1. Define DoC in the Inspection Location on the Equipment Details Page. This step is mandatory if DoC will be recorded on a Location basis, but not if data is per Kilometer Point (KP).
2. Set the Design DoC in the 3PD tab.
3. Import data via an ECH.
4. Review data in the Survey module.

## Step 1: Add DoCs to the Inspection Locations

To Add Docs:

- Navigate to the applicable Equipment Details Page.
- Add [Inspection Locations](https://ims-handbook.cenosco.com/v410/docs/plss-equipment-details-page#inspection-locations) of the Type “Depth of Cover”.

## Step 2: Define the Design Depth of Cover

To define the Design Depth of Cover (Design DoC):

- On the Equipment Details page, navigate to the Sectioning section.
- Click the [**3PD**](https://ims-handbook.cenosco.com/v410/docs/plss-equipment-details-page-for-pipeline-flowline-and-pipeline-jumper-for-carbon-steel-pipe#third-party-damage).
- In the Depth of Cover grid, [add Pipeline Section(s)](https://ims-handbook.cenosco.com/v410/docs/plss-equipment-details-page-for-pipeline-flowline-and-pipeline-jumper-for-carbon-steel-pipe#adding-new-sections) and specify the Design DOC.

Example

An example is given below where three Sections over the total length of the Pipeline were defined along with their respective Design DOC.
