2.11 Checklists
Emphasis should be on the hardware installation and on system settings that cannot be altered
during post processing: frequency, pulse length (number of pulses), range and gain.
Transducer Installation
 Correct transducer type is used.
 Transducer face, cable and connector checked for damages.
 Transducer is mounted horizontally in stiff frame or supporting structure.
 Transducer is decoupled acoustically from the ship’s hull by elastic material (rubber).
 Transducer is located as far away as possible from noise sources.
 Transducer is covered by water at all times, even at rough sea conditions.
 An additional ground wire is going from the transducer’s housing to the topside unit.
 The transducer cable is protected and will not vibrate.
 The draught of the transducer is measured and noted.
Topside Unit Installation
 Topside unit is placed in a dry environment.
 Cooling slots (bottom, front and rear panel) are free and there is space for airflow.
 Main power supply is checked. If a generator is used, a ground wire is connected.
 Power cable is plugged in.
 Transducer cable is plugged in.
 Ground wire from the transducer is connected to the topside unit.
 Additional sensors (Motion sensor / GNSS) are connected to the specified ports.
 Check if all connectors are fastened properly and all cables are fixed.
System power-up
 Make sure the transducer is below water level and covered by water all times.
 Switch on main power  the power switch and all power LEDs are lit green, “Sync OUT”
starts flashing.
 Start the SESWIN software  “HV” LED turns on, SBP echo plot part of the SESWIN
window starts scrolling from right to left. If not, check the synchronisation mode.
 SESWIN “System status” checked  OK.
SESWIN settings
 Set interface (GNSS, motion, …) ports.
 Set transducer’s draught and offsets / lever arms as appropriate.
 Check incoming GNSS (navigation) data (SIS fields populated correctly).
 Check incoming motion sensor data.
 Check all other settings in the “System Setup” dialogues.
System check / preparing survey start
 Switch on the transmitter [F4] (make sure the transducer is below water level).
 Set the range appropriate to find the seafloor.
 Optimize the gain settings for both channels based on the seabed return’s amplitude.
 Optimize the range settings based on water depth and required / expected penetration.
 Optimize frequency, pulse length (and gain) settings.
 Check and optimize the signal processing settings for online visualisation.
 Check the settings for annotation, profile number and marker counter.
 Check data record [F5].
