Note: The Ships Reference Point is an Arbitrary point close to the ships centre of Pitch and Roll.
It pays to make this point easy to measure to for improved accuracy of measurements. A good
guideline for a reference point is a point near the water line in the centre of the ship (port to star-
board) and half way down the length of the ship.
If using an SC30 the Motion Sensor posi-
tion is the same as the GPS position. If
the Motion Sensor is an SC50 measure the
position of the SC50 electronics box.
Commissioning should be performed by a trained WMB-160/80F technician
immediately after installation of the system.
The commissioning procedures are designed to be carried out in sequential
order. If a test fails, fix the system until that test can be completed satisfactorily
before continuing. Failure to do this may invalidate the commissioning procedure.
Commissioning procedures are divided into two sets:
►
Dockside Tests.
►
Sea Trials.
Dockside Tests
The first part of the commissioning procedures requires a number of
dockside
tests
to confirm that the WMB-160/80F system is installed and operating correctly,
before actually taking to sea.
Commissioning Step 1: Ship Measurements
Take measurements on the vessel between the vessel’s reference point, the GPS
antenna, and the transducer’s receiver face. These measurements must be as
accurate as possible. The accuracy of these measurements has a direct effect on
the accuracy of depth soundings. Enter these values in the spaces below, and on
the
Offset Corrections
tab in the

box. See Figure 27:
