16 RSK ENVIRONMENT LTD TRANS ADRIATIC PIPELINE PRE-CONSTRUCTION SURVEY 1. INTRODUCTION 1.1 General The Reson Seabat 711 multibeam echo sounder on board the MN ATLANTE was calibrated on 2 December 216. The calibration was undertaken over an area with several targets inside the survey area. The purpose of calibrating the system was to determine the angular difference between the pitch, roll and heading sensors with the multibeam head installation. 1.2 Background When the multibeam transducer, motion sensor and gyro are installed on a vessel, there is always going to be some residual misalignment between the sensors. During survey operations the multibeam data, with appropriate offset corrections, needs to be derived relative to true vertical. Any deviations in roll will translate to depth measurement errors in the outer beams, increasing with beam angle. Deviations in pitch will result in along track position errors. Similarly, heading (or yaw) offsets between the planes of the multibeam transmit beam and the alignment of the vessel reported by the gyro will result in position errors on the soundings from the outer beams. These errors will increase both with beam angle off nadir and water depth. It is also necessary to determine any latency within the positioning system to ensure that the data collection system is synchronized to GPS time. The difference in time from the moment when a position is valid until the position message is sent to the data collection system must be determined. Commonly used DGPS receivers have latencies ranging from 2 milliseconds to over one second. If the data collection system does not correct for this latency, the result is a speed dependent position error in the data. The positioning system used in the current survey has no latency, so the lines have not been run. 1.3 Pre Calibration The following operations were carried out prior to calibration: Location of appropriate calibration feature Draft measurement of echo sounders Gyro calibration Sound velocity Profile Check time offset of positioning system, motion sensors and echo sounders Check operation of motion sensors FOSPA MBES Report Page 2

18 RSK ENVIRONMENT LTD TRANS ADRIATIC PIPELINE PRE-CONSTRUCTION SURVEY Calibration Conditions Weather: Good Sea: Calm 1.5 Calibration Method 4 lines were run, 2 over the same location, two for yaw and two in opposite direction for roll, pitch, yaw and latency calibration. Calibration lines were processed using the Multibeam calibration software program within Fugro s Starfix suite to find correction values in the following order: 1. Roll 2. Pitch 3. Heading (or Yaw) 4. Latency Pitch Calibration A latency correction s was applied before deriving the Pitch offset error. Pitch offset error was measured from reciprocal lines that were run over the established point at a speed of 4 knots. The pitch offset correction of -2 was derived by iteratively reducing the differences in vertical angle through nadir along the track calibration line until the two data sets aligned. Roll Calibration A pitch correction of -2 was applied before deriving the Roll offset error. The roll offset error was measured by running reciprocal survey lines over a flat area of seabed then comparing the across track profiles against one another. The roll offset correction of 1.26 was derived by iteratively reducing the differences in horizontal angle along an across track calibration line until the two data sets aligned.

19 RSK ENVIRONMENT LTD TRANS ADRIATIC PIPELINE PRE-CONSTRUCTION SURVEY Heading (or Yaw) Calibration A Roll offset correction of 1.26 was applied before deriving the Orientation offset error. The heading offset error was derived by iteratively reducing the difference in orientation angle to a target resolved in 2 lines run in the same direction and apart. A heading offset correction of.6 was derived by iteratively reducing the differences in orientation angle of each swathe until the target aligned within the overlapping central region. 1.6 Results A summary of calibration results is given below: Table 1.2: Calibrations results Motion Sensor Calibration Date Latency (s) Pitch Error ( ) Roll Error ( ) Heading Error ( ) Teledyne DMS 55 2/12/ A good correlation of features was observed on overlapping lines after the application of calibration corrections.
