Configure Vehicle Text (Navigation and Waypoints)
Overview
The vehicle text window displays navigation, recording, and waypoint information.
Procedure: Configure Vehicle Text
To configure the vehicle text, perform these steps:
- Select Configure -> Vehicle Text to display the Configure Vehicle Text window (Figure 18), which allows the user to configure the number of rows and columns to be displayed on the screen. For each row, select the line contents from the Available Items list.
An example of what the text configuration will look like in Vehicle Window is shown in Figure 20. An extra row can always be added, for survey line information, in the event of a seismic survey. To specify an available item to a specific row, select the row number in the Row pull down menu in Figure 19.
Waypoints
Waypoints are sets of coordinates (longitude and latitude) that identify a point in physical space. In GPS navigation, a “route” is usually defined as a series of two or more waypoints. To follow such a route, the GPS user navigates to the nearest waypoint, then to the next one in turn, until the destination is reached. Our drill sites and ports-of-call are waypoints.
Adding Waypoints
To add a waypoint, perform these steps:
- Go to the top menu bar, select File -> Edit Working Files -> Waypoints. The waypoint.WPT screen appears (Figure 21).
- Select Add. Enter the name of the waypoint and the position. Optionally you may assign a color, icon and circle radius to help particular waypoints stand out.
- Click OK and the new waypoint appears on the graphics screen.
Waypoint Tracking
To set up waypoint tracking, perform these steps:
- 1. Select Configure -> Vehicles from the menu bar.
- 2. Click Setup Waypoint Tracking.
- Select the next waypoint the JR will track from the waypoints file in the Setup Waypoint Tracking window (Figure 23). When a waypoint is selected to track, the name and range will appear in the Vehicle Window.
When a waypoint is selected to track, the name and range will appear in the Vehicle Window.
WinFrog Data Logging
Overview
Logging data in WinFrog is performed by what are called Events. The user must define the data to be collected and at what interval of time. Data are written to two files:
- .dat
- .raw
The destination folders for these files are set up in the working directories window and should be set up at the beginning of each Expedition.
Data is collected at all times (for transits and while on-site) throughout an expedition. Start the:
- Transit event just as you are leaving port or your site
- Site event just as you come on to site.
Procedure: Data Event Set-up
To start logging an event for a transit or at a hole, perform these steps:
- Select Configure -> Data Events -> Setup from the top menu to open the Event Configuration.
- Select the Eventing tab, if it opens in different tab in the Event Configuration window.
- Select the Time button in the Trigger subwindow.
- Select the Manual Start button in the Event Start subwindow.
- Select the Data Logging [.DAT] button in the Record Type subwindow.
- Set the interval in which data will be recorded (blue dashed box in Figure 24).
- Select the Raw Data tab.
- Select the At Events button in the Logging Control subwindowso raw (*.raw) data will be collected at the same interval as the eventing (*.dat) data.
Click OK and the Event Secondary Configuration window opens (Figure 25). This is an option to setup another event log file with a new filename.
- If you want to setup your next event, type the file name in the File Name box.
- Expeditions use the expedition number, underscore, followed by the line or hole number (e.g., 317_U1338A).
- Transits use an “L” to indicate line, a number for the line number, and “T” for transit (e.g., L1T).
- A survey line will use an “S” (e.g., L4S).
- Holes will use the hole number which consists of the site number and the hole letter designation (e.g., U1338A).
- Click OK.
In the Vehicle Window, notice how the fields related to eventing are enabled and ready to be started (Figure 26).
Start Event Logging
On the Main Screen, click the green Event Start (FX) icon (Figure 27) to start data logging. Now data are being logged.
Stop Event Logging
To stop event logging, perform these steps:
- Click the red STOP icon (Figure 28) to suspend event logging and open the Event Secondary Configuration window (Figure 25). The user can:
- Cancel at this point
- Change the name to the next file to be recorded
Keep the same name and continue logging to it by appending more data (the user will be prompted with the option to append or overwrite).
Note The naming scheme has changed in the new Winfrog version.
- Click OK or Cancel, depending on the action to be done.
- Click the green (FX) icon on the main menu (Figure 27) to continue logging.
WinFrog Site Fix
Overview
The Operations Superintendent will need a position (latitude, longitude) for each hole. The position will be determined by averaging the navigation data fixes recorded while the drill string is in the hole. The data are from the IODP Forward and Aft GPS. Although a separate Site Fixer program is available to IODP Techs, WinFrog also has a Site Averaging Utility.
Data Event Logging
When coming on site, stop your transit data event and start a new data event for the site’s first hole as described in the Data Event set-up procedure. Remember to create a new event data file (ex. U1337A.dat) for each hole.
Position Averaging
WinFrog utilizes a utility called Position Averaging to average a position for a vehicle. Fugro Pelagos modified their position averaging utility for IODP in order for us to utilize recorded data files to determine hole positions.
Procedure: Select FILEs
To average a position for a vehicle, perform these steps:
- Select Utilities -> Position Averaging from the top menu to open the Position Averaging window.
- Select Reprocess Position Averaging Data from Disk.
- Under Position Averaging (Figure 29), select Load (red arrow left figure). The Select Position Averaging Data window will appear (right figure).
- Click on Select Files (blue arrow right figure) and browse to the correct data file (dashed blue box).
Determine Position of a Hole
Once the file has been selected, the time window of data must be selected. Determine the time window in which the drill string was in the Hole (GMT) by performing the steps in the Procedure: Determine Hole Position. To be safe, shave off 15 minutes or so from the beginning and end of the window. This will throw out most of the potential outliers as the ship settles into position. The key is to only use data collected when the pipe is actually in the hole.
During Expedition 321, the Operations Manager suggested using a time range of core 3’s time on deck (TOD) to the TOD of the last core of the hole.
Procedure: Determine Hole Position
To determine Position, perform these steps:
- In the Select Data to Load section of the Select Position Averaging Data window (Figure 30), enter the range of time (red oval) the pipe was in the hole.
- Click the Scan Files button (red arrow), which checks the file to see if the time window selected is in the file.
- Click OK.
- The Position Average for J. Resolution window (Figure 31) will display the Mean Position and Standard Deviations. An acceptable position has standard deviations less than two meters. You can also get the Northing and Easting values by selecting the Grid button to the right of the Mean Position.
- If the position is acceptable, enter a comment in the comments field (red box in Figure 31) (ex: site/hole information).
- Provide the information to the Operations Manager by taking a screen capture of the active window (<Ctrl> - <Alt> - <Print Scrn>) and then pasting the capture into Microsoft Word or following the PC Screen Shot Capture Instructions document located in Cumulus to save the screen capture as a tif file.
- Click on Save (green box). Save this file to the Expedition’s Position folder. The file extension is .aep. Use a file name with the Expedition and hole (i.e. Exp321_U1337A.aep). This file can be loaded into the Position Average Utility to view again.
- You can also provide a cover sheet for the screen capture, making the important information easier for them to parse (see Position Averaging Report).
Position Averaging Report
From Figure 31, select the Save option and navigate the file to be placed in the Expedition’s position folder. An .rtf file is created, where the screen capture can be pasted and a PDF generated. Print the document and give to the OPS Manager (and/or Staff Scientist if you wish). Save a copy to the Position folder.
If the position is not acceptable go back to Determine Position of a Hole (Figure 29) and try the following:
•Change the window of time (this may take a few tries).
•If you can identify some bad data, go to the Observed Data section, select those points not to be used, and click Re-Calculate.
