Abstract:
This invention relates to a metal pressure vessel with a cylindrical center section greater than about 3 meters in diameter and one or two frustum end sections having a diameter at the truncated apex of the frustum of about two meters or less.
Abstract:
An internally coated pipe (10) for CNG distribution or delivery is disclosed, wherein the pipe is made of a thermosetting plastic material (3), and the internal coating is made of a metallic material (5). The thermosetting material (3) provides the required strength for the pipe (10), for handling the pressures to which the pipe will be exposed, e.g. up to 100 bar, whereas the metallic layer (5) provides the required impermeability to the component parts of the CNG.
Abstract:
The present invention relates to a high pressure vessel for containing or transporting gas at ultra-high pressures. More particularly it relates to such vessels for containing or transporting compressed natural gas at these pressures and methods of manufacturing them. The present invention also relates to a method of storing or transporting gas onshore or offshore.
Abstract:
A watercraft comprising a diesel fuel tank for fuelling general shipping requirements of the watercraft such as motoring from one location to another, wherein the watercraft additionally has a CNG pressure vessel thereon for storing CNG therein, said CNG being useable by the watercraft, from the pressure vessel, for powering an engine for coastal manoeuvering of the watercraft.
Abstract:
An ISO modal container for storage and transportation of a CNG pressure vessel comprises a main longitudinal portion and two end caps, one at each end of the main longitudinal portion. The container comprises a frame body for housing a single pressure vessel inside said frame body. The frame body comprises two sides connected by longitudinally extending beams. A pair of attachments, one at each end of the pressure vessel, holds the pressure vessel suspended in place inside the frame body, with the longitudinal portion of the pressure vessel substantially parallel to the longitudinally extending beams of the frame body of the container. The pressure vessel is typically of the type 3 or type 4 class.
Abstract:
A pressure vessel is produced for storing and transporting CNG. The vessel comprises a body defining an internal volume in which the CNG can be stored, and an inlet for loading the CNG into the vessel. The body of the vessel comprises a structural shell made entirely of a fibre-reinforced filament-wound composite material, which is provided with fibres to carry mechanical loads and a matrix to keep the fibres together and to make the composite impermeable to the CNG. Because the vessel is not provided with any liner, the CNG is in direct contact with an inner side of the structural shell.
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:
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:
This invention relates to methods of fabricating components of a pressure vessel using a dicyclopentadiene prepolymer formulation in which the purity of the dicyclopentadiene is at least 92% wherein the formulation further comprises a reactive ethylene monomer that renders the prepolymer formulation flowable at ambient temperatures and to pressure vessels that are fabricated by said methods.
