Important
The installation trunk must be secured to
the bulkheads and/or the hull by means
of strengthening plates (stiffereners).
The dimensions and strength of the
plates must be adequate to prevent any
vibrations. This is an invariable requirement to ensure the safety of the MF90 system and
the vessel.
The shape and locations of the strengthening plates must be determined by the installation
shipyard based on the physical properties of the installation trunk, the hull and the space
available. Minimum four strengthening plates must be used. Each strengthening plate must
extend all the way from the bottom to the top of the installation trunk. Only leave a small
gap to allow access to the bolts and nuts used to secure the mounting flange. The minimum
plate thickness is 10 mm, but the classification society can specify other dimensions.
