Abstract:
Provided are an LNG storage container with an inner shell, which is capable of efficiently storing LNG or pressurized LNG (PLNG) pressurized at a predetermined pressure and supplying the LNG or PLNG to a consumption place, and capable of reducing manufacturing costs by minimizing the use of a metal having excellent low temperature characteristic, and a method for manufacturing the same. The LNG storage container includes: an inner shell configured to store LNG inside; an outer shell configured to enclose the outside of the inner shell such that a space is formed between the inner shell and the outer shell; a support installed in the space between the inner shell and the outer shell to support the inner shell and the outer shell; and a heat insulation layer part installed in the space between the inner shell and the outer shell and configured to reduce a heat transfer.

Abstract:
Gas supply device comprising a frame (2) housing a set of pressurized-fluid cylinders (3) linked to a fluid circuit (4, 5) for filling and emptying the cylinders (3), the support frame (2) comprising a lower base (34) on which the cylinders (3) rest vertically and a set of uprights (30) and cross beams (31, 32, 33) forming a cage with an overall parallelepiped shape to provide lateral support for the cylinders (3) arranged in several contiguous rows, characterized in that it includes at least one rigid reinforcement bar (6) for the frame (2) arranged between two rows of contiguous cylinders (3), said at least one reinforcement bar (6) resting simultaneously on the upper surface of the cylinders (3) in two rows of adjacent cylinders (3), the reinforcement bar (6) having two extremities connected rigidly and respectively to two opposing faces of the frame (2).
Abstract:
The invention relates to a gas distribution system including a gas container, a valve assembly and a protective cap arranged around said valve assembly. The valve assembly includes a rotary control member, which can be manoeuvred by a user, cooperating with a gas passage control system for controlling the passage of gas when it is manoeuvred by a user. The protective cap including an opening in which the rotary control member is housed, which is bordered by a projecting rim projecting away from the external lateral surface of the protective cap. The projecting rim includes a cut-out forming a reading window coming to be positioned facing at least one marker carried by the peripheral region of the rotary control member so as to enable a user to view said at least one marker through the reading window.
Abstract:
The present invention provides a sub-frame (10) for a valve body (12) having two or more location surfaces (14, 16), said sub-frame (10) comprising a first and a second portion (10a, 10b) having mutually confronting contact surfaces (18a, 18b), sides (20a, 20b) and front and back surfaces (22a, 22b) and mutually confronting engagement surfaces (24a, 24b and 26a, 26b) wherein said mutually confronting contact surfaces (18a, 18b) are shaped to engage with each other upon placement together of the two portions (10a, 10b) and said mutually confronting engagement surfaces (24a, 24b and 26a, 26b) are shaped to engage with one or other of said one or more location surfaces (14, 16) on the valve body (12).
Abstract:
A gas pressure regulator adapted for being mounted to a gas cylinder is provided. The gas pressure regulator includes a body defining a front portion and opposed side portion and a plurality of gas pressure indicators mounted to the front portion of the body. A bonnet is mounted to an exterior portion of the body, and a pressure adjustment knob is mounted to one of the side portions of the body, proximate the bonnet, and horizontally relative to a longitudinal axis of the pressurized gas cylinder. An energy absorbing device is operatively engaged with the pressure adjustment knob and the bonnet, the energy absorbing device being capable of absorbing energy from impact loads imposed on the pressure adjustment knob.
Abstract:
A system for support of a vertical cargo tank resting on an insulation layer against the hull of a vessel is arranged such that vertical forces are supported through the base of the tank. Horizontal forces are supported by support point pairs. These pairs are designed to direct applied forces generally through the middle of the shell of the tank in order not to apply bending moment to the shell of the tank. The base of the tank is flexible to generally distribute transferring forces from the tank directly to the bottom of the vessel in order not to apply bending moment to the shell of the tank or to the bottom of the 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:
Herein a floating vessel is disclosed. The floating vessel comprises a body structure, a tank for at least temporarily storing a liquid, and at least one pipe connected to the tank. The floating vessel further comprises a tunnel having a first end portion and a second end portion extending through the body structure. The tunnel is arranged in open connection to an ambient environment of the floating vessel. There is least one pipe connected to the tank extending at least partially through the tunnel.
