Abstract: A system for loading and storing CNG onboard of a ship and for unloading it therefrom comprises CNG loading facilities for loading CNG on board of the ship, CNG storage facilities for storing the loaded CNG on board of the ship at nominal storage pressure and temperature, and CNG unloading facilities for unloading CNG to a delivery point. The delivery point requires the unloaded CNG to be at delivery pressure and temperature generally different from the storage pressure and temperature. Thus, the CNG unloading facilities comprise a CNG heater for heating the to-be-unloaded CNG prior to unloading, and a lamination valve for allowing the to-be-unloaded CNG to expand from its storage pressure to the delivery pressure. A compressor may also be provided to compress CNG that would not otherwise be spontaneously delivered.

Abstract: This invention relates to a pressure vessel having a one-piece polymeric composite with a weldable metal fitting such that the pressure vessel can be coupled to a source of compressed fluid by a welded connection.

Abstract: This invention relates to a pressure vessel that is wrapped with a high-tension winding that prevents or ameliorates the effects of fatigue due to cyclic pressurizing and de-pressurizing of the vessel.

Abstract: A method of producing a pressure vessel, and the corresponding pressure vessel, wherein the pressure vessel is comprised of different types of structural elements, one of the structural elements being comprised of a metal substrate having a liner material adhering to the substrate in adjoining linear areas; and orientated so that adjoining linear areas of lining material are orientated longitudinally with respect to a completed pressure vessel.

Abstract: The present invention relates to a pressure vessel for containing or transporting pressurized gas. More particularly it relates to such vessels for containing or transporting compressed natural gas. The present invention also relates to a method of storing or transporting gas onshore or offshore. Moreover, the present invention relates to a vehicle for transporting gas, in particular compressed natural gas.

Abstract: A CNG transportation vehicle comprising at least one vernally oriented, generally cylindrical, pressure vessel (10) of the type for containing and transporting CNG, the vessel having a generally cylindrical body and two ends and an opening in the form of a manhole at the top end thereof.

Abstract: A pressure vessel for storage and transportation of CNG comprises a body, which defines an internal volume in which the CNG is stored and transported. An inlet is provided through which the CNG can be loaded into the internal volume of the vessel. At the end of said inlet there is a CNG expansion section through which the CNG expands into the vessel when loaded. The pressure vessel further comprises a CNG loading appendage for injecting the CNG at a point inside the internal volume of the vessel, thereby increasing the space between the expansion point of the CNG and the walls of the vessel.

Abstract: An inspectable pressure vessel (10) for containing a fluid such as CNG, the vessel having a generally cylindrical shape over a majority of its length, at least one opening for gas loading and offloading and for liquid evacuation, at least one stainless steel layer as a first layer (100) for being in contact with the fluid when the fluid is contained within the vessel, the first layer being made of low-carbon stainless steel, and a further external composite layer (200) made of at least one fiber-reinforced polymer layer that will not be in contact with the fluid when the fluid is contained within the vessel.

Abstract: The present invention relates to a method of rotational moulding where a heating structure is incorporated into the mould. Further aspects of the invention relate to a mould for rotational moulding comprising a heating element. In an embodiment, the mould is a pressure vessel for transporting and storing compressed natural gas. The heating element may be incorporated into the pressure vessel, or may be placed in contact with the pressure vessel for the duration of the rotational moulding process.

Abstract: A system for loading and storing CNG onboard of a barge and for unloading it therefrom comprises CNG loading facilities for loading CNG on board of the barge, CNG storage facilities for storing the loaded CNG on board of the barge at nominal storage pressure and temperature, and CNG unloading facilities for unloading CNG to a delivery point. The delivery point requires the unloaded CNG to be at delivery pressure and temperature generally different from the storage pressure and temperature.
