AI Technical Summary

Benefits of technology

The present invention provides a device called "shell" which consists of two distinct portions: an emerged portion and a submerged portion. This simplifies the manufacture of the device by separating the abovementioned issues. The features of each portion can thus be optimized, allowing for the selection of materials with distinct properties, adapted to the respective media and desired characteristics. The upper emerged portion has mechanical strength and UV light resistance, with a small surface area that allows for more expensive materials. The lower submerged portion has flexibility, low specific gravity, ease of cleaning, hydrophobicity, lightness, resistance to materials and substances with which it is in contact, and can also be used as a containment device. The upper and lower portions of the shell have different materials, thicknesses, and densities. The upper portion has multiple layers and a specific gravity of 5. The lower portion has a specific gravity of less than 1. The lower portion consists of at least one outer layer that is at least partially separable. The upper portion has means for fastening to the object to protect.

Problems solved by technology

Although the cleaning is easier than that of the hull of the ship, which requires drydocking and renewal of antifouling, this procedure remains unpractical.

Embodiment Construction

[0029]The following description, with reference to the appended drawings is given as a non limiting example and will allow for understanding the invention and how it can be embodied for a ship.

[0030]Appended drawings:

[0031]FIGS. 1 and 2 show a view of a containment device, the protective and / or treatment shell according to the invention, arranged on the mostly submerged portion of the hull of a ship.

[0032]FIGS. 3, 4, 5, and 6 show diagrams of shells of various forms made of two portions, 1 and 2, building up the device, to adapt to different types of ships.

[0033]FIGS. 7, 8 and 9 show a type of final assembly of the two portions 1 and 2 building up the device;

[0034]FIGS. 10, 11, 12, 13 and 14 show temporary types of assemblies, with portions 1 and 2 separable or partly separable.

[0035]FIGS. 15, 16, 17, 18, 19, and 20 show various types of films.

[0036]FIGS. 21, 22, 23 show the possibility of adding a foamed plastic to the emerged portion 1.

[0037]FIGS. 24 to 27 show variants of the clo...

Abstract

A device for the containment, protection and / or treatment of a submerged surface such as a ship hull, includes a flexible and impervious or non-impervious shell, including two portions, an emerged portion (1) and a submerged portion (2) having different features.

Description

TECHNICAL FIELD OF THE INVENTION[0001]The invention relates generally to the protection and / or treatment of a submerged surface such as a ship hull.[0002]More particularly, it relates to a device for the containment, protection and / or treatment of a submerged surface such as a ship hull (other non-limiting examples: surfaces in contact with water: finger pier, beacon, offshore platform, dock, barge, swimming pool, pond, floating homes) comprising an impervious or semi-impervious flexible shell made of several portions: a mainly submerged lower portion and a mostly emerged upper portion.TECHNICAL BACKGROUND[0003]All of the surfaces of objects, structures, ships or buildings submerged in water cover with algae or molluscs. To avoid or minimize this problem, the most frequently used method is antifouling (most often through paint biocide). However, firstly, this technique forces to clean the hull and repaint it every year, thus drydocking the ship. Secondly, continuing contact between ...
