Floating marinized water bath vaporizer utilizing a slosh chamber having reduced water surface area to reduce the effects of wave created which the vaporizer is in motion, and systems utilizing such vaporizer, and to methods of making and using such vaporizer.

A vaporizer apparatus for vaporizing liquefied natural gas (LNG) into vapor-phase natural gas for injection into an oil or gas well, comprises a blower assembly, a burner section, a heat exchanger section, and at least one flammable gas concentration sensor. The blower assembly comprises a primary blower configured to move air along an air flow path through the vaporizer apparatus and a flame arrestor configured to allow passage of the air into the vaporizer apparatus and impede passage of a flame out of the vaporizer apparatus. The burner section comprises an enclosure having an upstream end coupled to the blower assembly and a downstream end, and a burner inside the enclosure and in the air flow path for heating the air. The heat exchanger section comprises an enclosure having an upstream end coupled to the downstream end of the burner section enclosure and a downstream end, and at least one LNG heat exchange tube inside the enclosure and in the air flow path, and thermally communicable with the air heated by the burner. The at least one flammable gas concentration sensor is in the air flow path upstream of the burner and is configured to detect whether a concentration of a flammable gas in the air is above a flammable gas concentration set point.

A cryogenic vaporization system and a method for controlling the system are provided. The system includes a first vaporizer arrangement and a second vaporizer arrangement configured for receiving a liquid cryogen and outputting a superheated vapor. The second vaporizer arrangement is connected in parallel with the first vaporizer arrangement, and includes one or more banks of ambient air vaporizer (AAV) units or loose fill media with a high heat capacity. The second vaporizer arrangement has a different configuration than that of the first vaporizer arrangement. The system further includes at least one control valve controlling provision of the liquid cryogen to at least one of the first vaporizer arrangement and the second vaporizer arrangement.

Systems and methods for a heated gas cylinder assembly are disclosed. The heated gas cylinder assembly may comprise a cylinder shell and a heat exchanger disposed within the cylinder shell. The heat exchanger and the cylinder shell may define an interior chamber configured to hold a gas mixture. The heat exchanger may comprise an inner bore configured to receive a pyrotechnic composition. In response to igniting the pyrotechnic composition, the heat exchanger may provide thermal conduction to the gas mixture. The gas mixture may be simultaneously heated and released, or the gas mixture may be preheated before release.

A ship including a gas re-vaporizing system according to the present invention includes: a ship body; a vaporizer which is arranged in an upper portion of the ship body, and vaporizes liquefied gas and supplies the vaporized liquefied gas to a demander; and a heat source supply apparatus which is arranged inside the ship body and supplies a heat source to the vaporizer.

A fuel storage and distribution system for a gas-fueled sea-going vessel includes a tank room that constitutes a gastight space enclosing tank connections and valves associated with them. A part of a refrigeration or air conditioning circuit reaches into the tank room. A first local heat transfer circuit is configured to receive heat from the part of the refrigeration or air conditioning circuit in the tank room and arranged to transfer such received heat to liquefied gas fuel handled in the fuel storage and distribution system.
