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.

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: The present invention is directed to a protected pressure vessel comprising a one-piece electrically conductive composite boss that is isolated from contact with materials that have an electrical potential that differ from that of the conductive composite boss so as to substantially eliminate the possibility of galvanic corrosion cause by the differences in electrical potential.

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: 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: The present invention comprises a method of forming a thin metal layer on a dicyclopentadiene polymer surface and to constructs comprising the metalized layer.

Abstract: This invention is directed to pressure vessels in which the strength necessary to withstand the pressure exerted by a contained fluid under intended operating pressures is provided by a dry filamentous over-wrap.

Abstract: This invention relates to dicyclopentadiene polymer liners for systems used for the transport of fluids, in particular corrosive fluids and pressurized fluids such as compressed raw natural gas.

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: The present invention relates to a fire resistant pressure vessel in which the inclusion of fire resistance does add appreciably to the overall weight of the vessel over a similar vessel that is not fire resistant.
