Leaders in Pipeline Survey Systems OVERVIEW 2.1. Introduction This section described the C-Scan Pipeline Survey System model 2010: what the system comprises, how to unpack it, set it up and get it started. A detailed contents list for this section appears below.
Leaders in Pipeline Survey Systems 2.2. Unpacking and activating the C-Scan 2010 Detector Unit (DU) 2.2.1. Unpacking For shipping safety the Detector Unit is shipped with its batteries packed separately. Unpack the entire system from its yellow transportation case and make sure all the items, including those stored in the lid of the Signal Generator, are present in accordance with the packing list.
Leaders in Pipeline Survey Systems 2.2.3. Charging the Detector Unit (DU) The DU can be powered by C cells or D cells depending on the model. The picture below shows the two types. D Cells 4.5Ahr NiCd On/Off Switch C Cells 4.5Ah NiMH On/Off Switch The DU can be powered either by re-chargeable NiCad, NiMH batteries OR by alkaline...

Leaders in Pipeline Survey Systems NOTE: Subsequent removal/ replacement of the batteries will necessitate this same date/time setting procedure because these batteries power the clock. Hence the clock settings are lost every time the batteries are removed or replaced or the Main Power Switch in the battery compartment is turned to ‘OFF’.

Leaders in Pipeline Survey Systems This indicates a timer that counts backwards, the time displayed being the maximum time allowed to charge the batteries. If the batteries are charged before that time has expired (counted down to zero) charging will be terminated and the unit switched off automatically. If it is necessary to terminate the charging cycle before the batteries are fully charged and the unit has turned itself off, the charging cycle may be ended by pressing the X key.

Leaders in Pipeline Survey Systems OPERATION 4.1. Introduction This section describes the C-Scan Pipeline Survey System model 2010 in normal operation by using a detailed familiarisation practice session in the System’s built-in DEMO MODE. Please refer to the accompanying SURVEY PROCEDURE manual for more detailed information 4.1.1.
Leaders in Pipeline Survey Systems 4.2. Demo Mode Demo Mode enables all functions within the C-Scan model 2010 to be simulated. Four ‘standard’ surveys have been stored in the unit’s memory. The tables below show the data for these surveys: Survey 1 Current Depth...
Leaders in Pipeline Survey Systems 4.2.1 Starting DEMO MODE Switch on the C-SCAN: Press Press Menu Press SETUP Press Demo Screen will show DEMO ON Press X to return to main screen. NOTE: since we are in DEMO mode GPS cannot be used.
Leaders in Pipeline Survey Systems We have now completed the first ‘virtual’ survey. In a real situation, a surveyor may do a number of surveys before downloading the data. As the first survey is complete, we now need to know how to create a ‘new’ survey. The start screen should be shown and still be in Demo Mode: if it isn’t, re-select Demo Mode as explained above.
Leaders in Pipeline Survey Systems Continue the survey. NOTE: on the next SEARCH screen the survey number has been incremented to S#01 (the first survey is survey S#00). The point counter increments and does not reset to zero. Referring to the survey list, continue through to Survey 4. Note that on Survey 4 there is no GPS data.
Leaders in Pipeline Survey Systems There are three ways of entering distance. The first two we already know – GPS and direct distance i.e. the distance between points. The third way is chainage. 4.5. Chainage Chainage is the term given to incremental distance from the survey start point. As an example, a survey has 4 points taken 100m apart.
Leaders in Pipeline Survey Systems NOTE: We may freely switch between CHAINAGE and DISTANCE. When we enter a distance, the chainage is automatically stored (it is displayed on the attenuation display). The chainage start point is used to start a new survey. This point does not have to be zero. As an example, consider a survey of four points.
Leaders in Pipeline Survey Systems The graph on the left shows attenuation as the points were gathered (sequenced in time). The graph on the right shows the points sequenced for chainage. To switch between the two, press Use the ‘◄# and #►’ arrow keys to choose a section of the survey. As we can see the attenuation between #02 and #04 is 19.25 mB/m.
Page 31
Leaders in Pipeline Survey Systems Use the ◄# and #►arrow keys to select which survey to display, then press the tick key. The survey number is shown (S#000) and the survey points are also shown (#000 - #006) Once you have selected your chosen survey, you can view the stored information as you would during a survey –...
Leaders in Pipeline Survey Systems 4.8. Close Interval Survey When a normal survey is proceeding, it is desirable to find the position of a fault. Close interval mode is used to pin-point a fault to within +/-1m (or better depending on conditions).
Page 33
Leaders in Pipeline Survey Systems The UP and DOWN keys allow zooming in on the graph. Press X to ignore the sample and retake the reading. Press to accept the reading. Move along the pipeline the next interval point (in this case 5m) and use the circle and overhead bars at the top of the screen to ensure you are correctly sited over the pipeline.
Leaders in Pipeline Survey Systems 4.9. Notes on GPS GPS is an abbreviation for Global Positioning System. There are 24 satellites in low-earth orbit. The GPS receiver in C-Scan receives data from a number of these (maximum 12) depending on which satellites are ‘in-view’.
Leaders in Pipeline Survey Systems When a survey is conducted in the open where the operator walks between survey points, it would make sense not to turn off the unit; however, this reduces battery life. A power saving mode has been introduced that enables the GPS unit to remain on whilst all other devices are switched off.
Page 36
Leaders in Pipeline Survey Systems There are messages that are displayed to tell the user which part of C-Scan is active. This can be summarised at the start screen Antennae OFF Antennae ON All menu functions switch off the Antennae. Similarly, if the unit has been idle on the START screen for more than 3 minutes, the antennae is switched off.
Leaders in Pipeline Survey Systems 4.11. PRINTING OUT A SURVEY After a survey has been completed it is probable that a printed report is required. There are two methods for doing this: 1. Use any PC based terminal program (e.g. Hyperterminal with windows). 2.

Leaders in Pipeline Survey Systems Print Cnvrt The key ‘Print cnvrt’ allows data to be paced correctly for a Patton electronics (www.patton.com) model 2029 serial-to-parallel converter, for direct connection to a parallel printer. Use this key when using the converter. DO NOT use the other keys. As a printer expects line-feeds, using the other keys will print out on ONE line.

(‘Browse’ key may appear if a survey is in memory) Press YES ( ) to erase all data, Pressing NO (X) will abort and all data will remain in memory. Issue 4.04 - 1207 OPERATOR’S MANUAL...
