Page 8: Intended Use Of The Equipment
FiGS 2.0 usage FiGS 2.0 is a sensor for measurement of cathodic protection activity and corrosion for assets in seawater, such as pipelines, subsea structures and fixed installations. - Page 9 The sensor consists of 3 main parts: Rotor Motor housing Electronics housing The sensor is built up with 3 sensing electrodes mounted on a rotating shaft. The rotating part, from now on called the rotor, will rotate at a speed of 250 or 500RPM when the sensor is in operation. The motor and part of the rotor is enclosed in the motor housing, which is oil filled and pressure compensated.

Page 13: Equipment Installation
Equipment installation Connect FiGS 2.0 sensor to the FiGS 2.0 power bottle with the supplied cable. Check that the power bottle is mounted the correct way. The power bottle is marked with “FiGS side” and “ROV side” on the bottle. If the power bottle is mounted the wrong way, the sensor will fail to power up. -
Page 14: Equipment Operation
Connect the sensor to the computer via the RS232 interface. The sensor can be controlled by a terminal software, such as Putty, or by a specific logging and control software. Protocol FiGS 2.0 FiGS can communicate over RS-232 at 19200, 115800 and 1000000 baud. The communication is ASCI based, i.e. -

Sensor head Electrode 4. For special cleaning, skip part 3 and place the sensor head in an ultrasonic bath with isopropyl alcohol for 2 minutes. Leave to dry and mount new cotton plugs and remount the electrode caps. 5. Cleaning of receptables: remove connector and O-rings and clean the receptable with a soft cloth soaked in isopropyl alcohol. - Page 31 o Oil-fill plug on motor housing Oil-fill plug o Oil-fill plug on penetrator Oil-fill plug o Around oil-filled hose...

Warning! Do not replace bolts! The bolts are made specifically for this sensor. Replacement of bolts made from other materials and /or other specifications may lead to water ingress and erroneous measurements. Replacement bolts can be obtained from FTN. Note: If any leakage is found, contact FTN for service. Unrepaired leakages will result in loss of oil and possibly loss of function of the sensor. -
