Brace the installation trunk to the hull plating and the surrounding hull frames
by adding several strengthening plates.
The plates must be at least 1.5 times as thick as the surrounding shell plating. The
final dimensions of the doubling plate must be defined in the approved installation
drawings supplied by the shipyard.
9
Stiffen the installation trunk in both the fore-and-aft and athwartship directions by
welding strengthening knee-plates both to the trunk and to the doubling plate.

Depending on the shape of the hull, we recommend that you fit a steel blister for
protection.
The blister must be designed by the installation shipyard. It must be welded to
the shell plating. The blister may be an open type, or it can be filled with oil to
prevent corrosion. This last method provides excellent protection, and simplifies
maintenance.
Note
Make sure that the hull plating surrounding the trunk is even and smooth without
protruding objects that can cause noise. Objects protruding from the hull will
generate turbulence and flow noise. This will reduce the SC90 performance. If
necessary, grind and polish all surfaces.
11
As soon as all installation, welding and grinding has been done, prime or paint the
trunk and the surrounding area using a high quality protective coating.
You must also apply the protective coating to the inside of the installation trunk.
12
Inspect the installation of the installation trunk, the blister, hull plating and all
surfaces thoroughly.
