Problems solved by technology

Therefore, unless properly designed, under extreme weather or sea conditions, pressure vessels may experience external loads or bending moments that, due to stress concentrations in one or more of the pressure vessels on board the vessel, bend Moments may cause bending failure or buckling

Embodiment Construction

[0044] figure 1 Shown is an outer sheath, sleeve or layer 202 (in figure 1 "Type 3" multilayer CNG pressure vessel 10 in which the outer jacket, sleeve or layer is schematically represented by a cross-shaped dotted area), the insulating material is polyurethane foam in this example. A "type 3" vessel denotes a vessel having an outer structural layer made of composite, fiber reinforced material and an inner metal liner. The outer composite provides the structural strength of the vessel, while the inner liner provides an impermeable layer for containing the CNG.

[0045] Typical thermal properties of polyurethane foams are thermal conductivity in the range of 0.02 to 0.04 W / m·K at near ambient temperature.

[0046] An insulating sleeve covers the central cylindrical portion of the pressure vessel, which extends between the two end caps (first end cap 12 and second end cap 11 ). In this embodiment, both end caps 11 , 12 are equipped with their corresponding orifices eg for fil...

Abstract

A pressure vessel (10) for naval transportation of CNG comprises a vessel body adapted to receive and contain CNG, and an external layer (202) of a cushioning and thermally insulating material for insulating thermally at least a portion of the CNG. The thermally insulating material (202) is distinct from the vessel body. For example, it is a foam material. A rigid or semi-rigid skin or skirt (204) of a structural material can also be provided in contact with at least a portion of the cushioning and thermally insulating material (202), on the outer side thereof, to enable the pressure vessel (10) to be supported in a desired position on ships (301 ) or the like.

Description

technical field [0001] The present invention relates to pressure vessels and to shipboard support apparatus for pressure vessels, for example including means for holding a pressure vessel in a desired configuration or position on a ship, vessel or another form of vehicle, especially a watercraft equipment with structural elements. More specifically, the present invention relates to pressure vessels and supporting equipment for marine transportation of compressed natural gas (CNG). Background technique [0002] Natural gas is a valuable natural resource often found in natural underwater reservoirs. Natural gas may be extracted from such reservoirs and subsequently transported to land on ships, boats, and the like. The present invention relates to such transportation in which the natural gas is in the form of CNG. [0003] Onshore applications are also contemplated, such as extraction and transportation from natural underground reservoirs. [0004] CNG is a form of natural...
