Context
Mounting frames are designed to house the individual transducer modules. While the
transducer modules are mounted into the frames, the frames require casings.
The installation must be carried out according to arrangement drawings designed for the
specific vessel. Refer to the drawings included in the Drawing File, and the applicable
drawings prepared by the installation shipyard.
Note
The mounting frames must be handled with care. Please observe normal safety
precautions for dockyard work and welding.
Procedure
1 Mount the CCU (Cable Connection Unit) to the frame before the frame is installed.
The CCU(s) should be mounted on the side of the mounting frame.
2 Mount the frame in the casings.
The mounting frames must be bolted onto the flat bars inside the casing. The
number of flat bars depends on the length of the transducer array. There are three
(3) holes in each flat bar.
The frames are fastened by M16 bolts. Bolts of grade A4-80 should be used.
Use a torque of 187 Nm.
3 Check that the each frame is mounted completely flat.
Important
No point on the frame may deviate from the ideal plane with more than 0.6 mm.
The maximum allowed gradient between two adjacent mounting points on the
frame is 0.1 % (1 mm/m).
This can be checked by measuring the relative vertical positions of the module
mounting bars on the frames. If the deviations are too large, this has to be corrected
by applying shims.
When the frame is installed completely flat:
4 Remove one bolt.
5 Apply Loctite 242 to the bolt.
6 Install the bolt using a torque of 187 Nm.
