A.15 Checklists (Setup, Data Acquisition, Processing)
Checklist System Setup / Survey Start
Transducer Installation
 Correct transducer type is used (transducer S/N for “compact” and “light” starts with “C”; for
“standard” with “A”, for “medium-100” with “E”).
 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 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 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  power switch and all power LEDs are lit green.
 Start the SESWIN software.
 The SBP echo print part of the SESWIN window starts scrolling from right to left. If not,
check the synchronisation mode (“System Setup – Settings – General”).
SESWIN settings
 Set transducer’s draught in SESWIN “System Setup – Settings – General – System”.
 Check incoming SIS (navigation) data.
 Check incoming motion sensor data.
 Check all other settings in the “System Setup” dialogs.
System check / preparing survey start
 Make sure the transducer is below water level and covered by water all times.
 Switch on the transmitter [F4].
 Set the range appropriate to find the seafloor.
 Optimize the gain settings for both channels.
 Optimize the range settings.
 Optimize frequency, pulse length and gain settings.
 Check and optimize the signal processing settings.
 Check the settings for annotation, profile number and marker counter.
 Check data record [F5].
