Research Details

The invention relates to a system for the mass transport of natural gas at high pressure by sea, using 11-meter-long seamless steel cylinders (1) having the necessary characteristics and strength in order to comply with current standards. A composite cover (2) is added to the cylinders by means of pultrusion after the cylindrical zone (3) of the cylinder (1) or the thickness of the steel cylindrical zone (3) has been Machined by turning, thereby increasing the steel thickness semispherical of the zones (4).The cylinders (1) are subjected to an internal surface treatment involving cold deformation (Blasting), such as to produce residual deformations on the internal surface which induces stresses that counterbalance those caused by the internal pressure, since the Blasting treatment enables plastic deformation up to to pre-determine depth.

1. CLAIMS.

2. Mass transport system OF NATURAL GAS TO HIGH PRESSURE BY SEA, characterized by the fact that it consists of the use of bottles (1) of seamless steel large, preferably from about 11 meters in length, retain the qualities and resistance needed for the transportation of gas under current regulations, in that these bottles (1) adds an outer covering of composite (2) or composite material (carbon fiber, fiberglass or aramid fiber) being implemented by pultrusion, prior to mechanize the process by turning the cylindrical area (3) of the bottle (1).
3. Mass transport system OF NATURAL GAS TO HIGH PRESSURE BY SEA, according to claim 1, characterized by the fact that the bottles (1) they are applying a surface treatment through internal deformation in cold (blasting), getting residual deformations the inner surface tensions that lead to counteract those due to internal pressure, because the blasting permits a plastic deformation to a depth determined.
4. Mass transport system OF NATURAL GAS TO HIGH PRESSURE BY SEA, according to claims 1 and 2, characterized by the fact that optionally, you can apply the composite (2) on the thickness of steel cylindrical departure from the area (3 ) From the bottle (1), and increasing the thickness of steel from the areas hemisphere (4) of the bottle (1).
Description:
Mass transport system OF NATURAL GAS TO HIGH PRESSURE BY SEA

OBJECT OF INVENTION

The invention, as expressed by the wording of this description, refers to a mass transport system of high pressure natural gas by sea, which brings to the role to which a number of advantages, which will be described in detail below, which represent an innovative alternative to the systems known in the current state of the art for the same purpose.
In more concrete, the object of the invention is to transfer natural gas deposits in high pressure and temperature by sea, using a novel system and serving as an alternative to transport liquefied natural gas, based on the use of bottles or bottles of steel with carbon fiber and seamless large (up Hm long), while retaining the qualities and resistance to such transport of gas.

SCOPE
The scope of the present invention industry is dedicated to the transport of energy, especially natural gas.

BACKGROUND OF THE INVENTION
The methods currently used to transport carry natural gas from production centers to consumption centers are essentially two, pipelines and shipping in the form of LNG.
Most of the gas market in the world is transported through pipes, approximately 75%, the rest is transported in liquefied large LNG tankers.
The materials used in the bottles for shipping natural gas pressure range (aluminum, steel, composite materials, etc.).
Depending on the material used, its manufacturing method will be different.
Most of the bottles used for storing gas are made of steel and seamless, being the same size rarely exceeding two meters in length, so that their capacities are much smaller and are entirely inappropriate for transporting large quantity of pressurized gas over long distances, which is the objective of the present invention.
There are projects to the manufacture of bottles of similar size to which the invention proposes, but where the bottles are made of steel with welding, which entails serious security problems in transport.
It is worth mentioning, however, that the petitioner of this invention is unknown.
Existence of a mass transport system of high pressure natural gas by sea similar to that advocated by the advocates here, and that aim, as has been mentioned is to solve the problems described above show that the systems currently known to the same purpose.
 

EXPLANATION OF INVENTION
Thus, the mass transport system of high pressure natural gas by sea to the invention proposes, is by itself an obvious novelty within its scope, since according to their use is achieved in a practical way exhaustive and especially effective for the realization of such transport, which becomes a viable alternative methods in existence.
Fillip, as mentioned above, the invention advocates the transfer of natural gas stored in Tanks of high pressure at room temperature by sea, using a novel system based on the use of steel cylinders with carbon fiber without solder about 11 meters in length, while preserving the qualities and strength necessary to ensure the safety of the transport of gas. Fillip, as mentioned above, the invention advocates the transfer of natural gas
The bottles, cylindrical configuration of the type that are conventionally used for the transport and storage of such materials are made from steel-reinforced carbon fiber, the process to be conducted from a lower external perimeter of the zone Cylindrical and the subsequent implementation of the composite or by pultrusion,
alternatively, applying the composite on the thickness of steel cylindrical item in the area and increasing the thickness of steel in the hemisphere of the ends of the bottle, always serving the UNE-EN existing regulations for the design and construction of this type of bottles. It should be noted that the limitation on the length of the steel cylinders that the proposed invention is imposed by the capacity in the premises of manufacturers.
Specifically, the maximum size of the block depends on the ability of the oven used in the revenido.
In the case of bottles of a length greater than 11 meters, will be carried out changes in the facilities of the manufacturing process, where this is sufficiently profitable for the manufacturer.The new mass transport system of high pressure natural gas by sea is therefore an innovative solution to structural features and constitute hitherto unknown to the purpose for which it is intended, reasons linked to its practical usefulness, give the reasonable basis to obtain the exclusive privilege of being requested.
