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 buoy system for at least one of a) loading natural gas from a gas well or gas storage facility to a ship or b) offloading natural gas from a ship to a gas delivery network or storage facility, the buoy system comprising one or more offshore wave energy converter (OWEC) such that the buoy system is able to gather and store wave energy to be used during the relavant one or both of loading or offloading practices.
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:
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 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:
A system for offloading a compressed fluid from a series of pressure vessels, the system comprising a multilevel piping system and at least one ejector device, the ejector device being for recovering energy from a high pressure fluid stream from a substantially full pressure vessel, and for forced suction of residual fluid from a part offloaded pressure vessel, the multilevel piping system comprising, in use, at least three different pressure levels, including a high pressure line, a medium pressure line and a low pressure line, the high pressure line being intended to supply the said ejector device with the high pressure fluid stream, the medium pressure line being intended for both the forced suction of the residual fluid and mixing with the high pressure line, and the low pressure line being intended for each of mechanical suction of the residual gas not drawn off by the ejector, recompression thereof by means of at least one compression turbomachine, and assisting energy recovery by transferring heat via gas/gas exchangers.
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:
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. 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:
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.
