EM 122
Final installation checks
After installation - but before un-docking - a number of verification must be done to
check that the mechanical and electrical installation has been performed correctly.
Procedure
1
Check that the measured positions of the transducers, motion sensor and positioning
system antenna are reasonable by comparing them with those estimated from the
vessel drawings.
2
Check that the measured installation angles of the transducers is reasonable by
comparing them with measurements done with a simple inclinometer.
3
Check that the specified sacrificial anodes have been mounted, and that any specified
anti-fouling paint has been applied correctly.
4
Check that all system units have been fastened properly and that all nuts and bolts
have been tightened properly.
5
Check that the data from the motion sensor, the heading sensor and the positioning
system are correctly read by the EM 122 and that the values are reasonable before
un-docing.
The steps in this procedure may be incorporated in the “Harbour Acceptance Test” carried
out as a final check to test both the installation and the main functions of the system.
