1. MOUNTING

• Fit a doubling plate (a plate to reinforce the
hull plate) of 600 mm or more diameter to
the outside of the hull plate (see the figure to
the right). For the doubling plate, use the
same material and thickness as hull plate.
• Weld four reinforcement plates to the retraction tank.
• If the length of the retraction tank (Li) is more than 1 m, install at least one reinforce-
ment rib to prevent damage of the tank and vessel. One reinforcement rib should be
installed toward the ship’s bow (see the following figure). It is recommended that
four reinforcement ribs are installed.
• For the reinforcement ribs, fit doubling plates to the location where the reinforce-
ment ribs are welded to the bulkhead of the vessel (see the following figure).
