Verifying the quality of the hull unit
installation
A quality inspection must take place after the hull unit has been installed, and while the
vessel is still in dry dock. The inspection shall verify that the sonar room meets the
requirements, and that the hull unit has been installed correctly.
Prerequisites
Neither tools nor instruments are required.
Context
The sonar room is the compartment in which the Transceiver Unit, the Power Supply
Unit and the hull unit are installed.
Procedure
1 Make sure that the hull unit is installed in the correct location, and that it is suitably
oriented for easy maintenance and replacement of parts.
2 Make sure that the unit is not physically damaged, and that the paint-work is clean
without dents or scratches.
The physical handling of the unit during the installation may have caused some
minor scratches to the paint-work. This can be accepted. However, if rough
handling has caused serious damage to the unit, this must be recorded with a written
statement and necessary photos, so that corrective actions can be made.
3 Make sure that the physical installation of the unit has been completed.
a Make sure that the welds and brackets used to support the hull unit are
substantial enough to hold the unit securely under all operating conditions.
b Make sure that the compartment ("sonar room") in which the hull unit is
mounted is clean and dry.
c Make sure that ample space is provided around the unit to allow for
maintenance and replacement of parts.
