Abstract:
The present invention relates to an independent vessel tank system for storing liquid gas. The system comprises a first tank member (1), a second, cylindrical tank member (2) connected to the first tank member (1) and a third tank member (3) connected to the second tank member (2), where the first, second and third tank members (1, 2, 3) provide a tank device for the liquid gas. A first supporting device (5) is provided between the third tank member (3) and a hull of the vessel, for supporting the weight of the tank device. A second supporting device (4) is at least partially provided along the periphery of the tank device, for supporting the tank device to the hull of the vessel.
Abstract:
The present invention discloses apparatuses, systems, and methods for controlling liquid impact pressure in liquid impact systems. The liquid impact systems include at least one gas and a liquid, the gas having a density ( PG ) and a polytropic index (κ) and the liquid having a density ( PL ). The methods include the step of calculating a liquid impact load of the liquid on the object by determining a parameter Ψ for the system, wherein Ψ is defined as ( PG/PL )(κ-1)/κ. The systems are also configured to utilize the parameter Ψ. The parameter Ψ may be adjusted to increase or reduce the liquid impact load on the system. Automatic, computer-implemented systems and methods may be used or implemented. These methods and systems may be useful in applications such as LNG shipping and loading/off-loading, fuel tank operation, manufacturing processes, vehicles dynamics, and combustion processes, among others.

Abstract:
The invention concerns a composite pressure vessel containing a smooth external composite shell (1), a smooth interlayer (3) of a viscoelastic material and an internal thin- walled metal lining (20) formed by a body in the shape of a ball or cylinder, with bottoms fitted with molds. At least a part of the body of the lining (2) is made as a thin- walled shell with regular molds and is isometric to the internal circular cylindrical surface of the interlayer (3) and/or to the internal conical surface of the interlayer (3), with the surface of the shell of the lining (2) being formed by interconnected elements in the form of parts of cut surfaces, arranged in a mirror-like manner, where the places of connection and bending create a light spatial frame of curved fins in which the short transverse partitions between the fins are located on the central surface of the elastic interlayer (3) of the vessel and the long transverse bridges between the edges touch the inscribed surface, on condition that the total volume of the molds exceeds the increase in the volume of the smooth composite shell (1) during deformation; profile dampening seals (4) of a flexible non-compressible material are inserted in the molds.
Abstract:
A novel inflation system for inflatable life jackets, comprising a gas reservoir of transparent plastic which stores liquid gas at a low pressure and which is connected to a casing which is transparent in full or in part and in which the opening mechanism for the gas reservoir is integrated and which has a profile for being attached to a receiving part connected to the inflatable life jacket and having an opening to the inner space of the life jacket, thus inflating the life jacket to the usage size by means of the spontaneous volume expansion for the liquid gas through both openings when the gas flows through a large outlet opening in the casing part, characterized in that the gas reservoir is surrounded by a casing such that the outer surface of said gas reservoir tightly abuts the inner surface of the casing.
Abstract:
A cellular reservoir flexible pressure vessel is formed as a series of closely packed tubes fitted into a pair of opposing end caps. The end caps have individual receptacles sized and shaped to receive the tube ends that are secured with adhesive or radio frequency welding. At least one end cap has a passageway for connection of the vessel. The flexible pressure vessel has a pressure relief device comprising a reduction in thickness of one end cap at a predetermined location. When subjected to overpressure it fails at the predetermined location. Other pressure relief devices include: a projecting member on the vessel surface, a weakened section of the passageway, a weakening or an absence of braiding material or hoop winding at a predetermined location on the vessel surface or along the passageway, a weakening or spreading of fibers in either the reinforcing panels or the flexible blankets covering the vessel.

A polymorphous reservoir structure for a pressurized liquid, comprising at least one outer shell, an enclosure for receiving a pressurized liquid, whereby said structure (2) is provided with one or more means of reinforcement (7,8, 9) and the choice and/or distribution of said means of reinforcement is determined by taking the mechanical characteristics into account in addition to the stress exerted by said pressurized liquid in order to meet at least one given stress state.
Abstract:
The invention relates to a tank (10) for storing compressed gas having a pressure of at least 15 Mpa, a casing layer (11) which encloses the hollow space (13) provided for storing the compressed gas, and at least one connection for loading and/or unloading the tank (10). In order to decrease the weight of the tank, the casing layer (11) can be constructed of plastic and/or a fiber material. According the invention, supporting elements (30) which are connected to the casing layer (11) are provided in the hollow space (13) of the tank (10) such that the tank (10) can be constructed in any geometric shape and can especially store gasses under high pressure. The supporting elements (30) can be constructed as filaments which are guided through the corresponding guiding canals (31). As a result, the supporting elements (30) assume the function of a seam. A liner (14) preferably constructed of plastic can be arranged on the inner surface (12) of the casing layer (11) in order to additionally seal the tank (10).
