Description
Purpose
The UKOOA format P5/94 is intended to facilitate the exchange of position data for pipelines, flowlines, umbilicals and power cables offshore (often collectively referred to as 'pipelines'). It allows the inclusion of some data in addition to pure coordinate data but is not intended to be used as an inventory of pipeline condition.
The data required for pipeline position are the Latitude and Longitude, Easting (E), Northing (N), Depth, Kilometre Point (KP), and feature where applicable, together with coordinate datum and projection parameters.
All coordinates within a file must be in a single coordinate system as given in the header records, i.e. if a pipeline crosses a grid zone boundary then a separate file for each zone is required. Similarly a separate file is required for each pipeline within a zone, i.e. if a feeder line is joined by tee-piece to a gathering line then one file is required for each pipeline.
The Qinsy P5/94 Generator driver employs an online user interface allowing recording of pipeline positioning data.
There are three variants of the P5/94 driver:
- Standard P5/94
- TS166 Generator
- UPIS Generator
A format description of the standard P5/94 is available under tab "Format"

UKOOA P5/94 Format Description
Executive Summary
The P5/94 format is available to members to facilitate the exchange of pipeline, other subsea flowlines, umbilicals and power cables’ position data.
Use of this format, which is a revision of the P5/86 format is not mandatory but it is strongly recommended that it be used wherever possible.
Comments and suggestions for improvement of the format are welcome and should be addressed to:

Introduction
UKOOA format P5/94 is intended to facilitate the exchange of position data for pipelines, flowlines, umbilicals and power cables offshore. (Collectively referred to here as pipelines). It allows the inclusion of some data in addition to pure coordinate data but is not intended to be used as an inventory of pipeline condition.
The data required for pipeline position are the Latitude and Longitude, Easting (E), Northing (N), Depth, Kilometre Point (KP), and feature where applicable, together with coordinate datum and projection parameters.
All coordinates within a file must be in a single coordinate system as given in the header records, i.e. if a pipeline crosses a grid zone boundary then a separate file for each zone is required. Similarly a separate file is required for each pipeline within a zone, i.e. if a feeder line is joined by tee-piece to a gathering line then one file is required for each pipeline.
Header Record Specification
Formats of parameter data fields for each of the header record types are: -

| Notes | Columns 1 to 4 of each Header Record are devoted to code for "type" of header e.g. H42, H501 etc. Header "types" H36X to H40X may be repeated to cater for different sections of pipeline surveyed at different times or with different positioning systems, or derived by digitisation. (X in the range 1 to 9) e.g. H361 to H401 may be first survey whilst H362 to H402 may be a second survey etc. H40X should be set to 1 if not applicable. Header record H53 may be repeated as often as necessary.

An estimate of the absolute accuracy of the surveyed feature should be supplied since this will assist in planning future operations. Positional accuracy will obviously depend on methods employed to survey the pipeline and its features. |

Database Setup
Defining a P5/94 Generator driver is very straightforward.
Add a New System.
Enter a name for the driver.
Select P5/94 Generator driver from drop down list:
Select the P5/94 driver type:
- Standard P5/94
- TS166 Generator
- UPIS Generator
Online
Standard P5/94
When starting the Online Controller, the P5/94 Generator driver with user interface is minimized in the bottom bar
The maximized dialog box is initially empty:
Unless in recording mode a guidance message pops up.
After starting recording, pressing the Fix button brings up the Edit Pipeline Feature Code window:
| Observation | |
|---|---|
| KP Number | The Kilometer Point number is reported for the instant the Fix button was pressed. It is not editable here. This is Item 3 in the Data Record Specification. |
| Pipeline Id/Code | Enter a identifying string for the pipeline. This is Item 2 in the Data Record Specification. |
| Feature Code | Select the code from the drop down list.  |
| Pipeline coverage status | Select buried or exposed. |
| Pipeline as-laid status | Select Trenched or Un-trenched. |
Press OK to generate the pipeline event.
Selections are reflected in the P5/94 Driver window:
The Pipeline Id/Code and Feature Code remain selected the next time the Fix button is pressed. This can be useful if a feature like 'Field Joint' is repeated often.
TS166 Generator
When starting the Online Controller, the P5/94 Generator driver with user interface is minimized in the bottom bar
The maximized dialog box is initially empty:
Unless in recording mode a guidance message pops up.
After starting recording, pressing the Fix button brings up the Edit TS166 Formatted Pipeline Feature Code window:
| Observation | |
|---|---|
| KP Number | The Kilometer Point number is reported for the instant the Fix button was pressed. It is not editable here. This is Item 3 in the P5/94 Data Record Specification. |
| Pipeline Id/Code | Enter a identifying string for the pipeline. This is Item 2 in the P5/94 Data Record Specification. |
| Feature Code | Select the code from the drop down list. Note that several additional codes have supplemented the standard P5/94 code list.  |
| Feature Text | Enter a descriptive alphanumeric character string. This text box is activated when a fix is made. 'Feature text' can only filled in when the P5/94 generator uses the TS 166 Generator driver or the UPIS Generator. |
| Burial Depth | Enter a numeric value. |
Press OK to generate the pipeline event.
