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

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.
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
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
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.
