Problems solved by technology

[0016] Inconsistent expansion of the foam in one hold relative to the foam in an adjacent hold can cause irreversible and unpredictable deformation of longitudinal members, affecting the durability of the structure
[0017] Deformation of the longitudinal members and shell of the hull as well as the deck can cause the boat to be scrapped and removed from the production line

Embodiment Construction

[0046] figure 1 Shown is a device with 3 units (identified by a number followed by a combined suffix a-c) for the simultaneous injection of packing into a ship with 3 separate holds.

[0047] The method of filling each individual tank is achieved by means of a fill formulation and injection unit that includes a number of components necessary to formulate a polyurethane fill fluid and then inject it into an individual tank. Thus, this device comprises a number of units equal to the number of holds to be filled.

[0048] For example, fillers consist of polyurethane liquids of the two-component type formed by mixing two previously separate reactants, such as isocyanate and polyol.

[0049] The polyurethane liquid is injected into the cabin at the same time, and due to the chemical reaction, the polyurethane begins to expand freely in the form of foam. For buoyancy reserve and unsinkability of the boat, the polyurethane foam is preferably a closed cell high density polyurethane....

Abstract

A device and a process for the injection of a filling material in a boat comprising a plurality of separate chambers. The filling material is prepared in a plurality of distinct preparation and injection units, corresponding in number to the number of chambers to be filled, and is then injected simultaneously into the chambers.

Description

technical field [0001] The present invention relates to an apparatus and method for manufacturing an unsinkable ship, and more particularly, to an apparatus and method for injecting filler into a ship comprising a plurality of independent holds. Background technique [0002] In the nautical field, the use of unsinkable ships made by incorporating buoyancy reserves is well known. [0003] A boat is made of two hulls joined together, one above, usually the deck, and the other below, the hull, usually made of fiber-reinforced resin. [0004] The buoyancy reserve is obtained by filling the "empty" space between the two hulls forming the boat, ie not the space used for cables and onboard systems. [0005] Fillers are usually made of closed-cell polyurethane foams prepared by mixing the different components (polyols and isocyanates) in preset proportions to react to form polymers, increase their Form swells. [0006] The volume expansion ratio between the expanded foam componen...
