Embodiments of systems and methods for transporting fuel and carbon dioxide (CO.sub.2) in a dual-fluid vessel thereby minimizing transportation between locations are disclosed. In an embodiment, the dual-fluid vessel has an outer shell with two or more inner compartments, positioned within the outer shell, including a first inner compartment for storing CO.sub.2 and a second inner compartment for storing fuel. The dual-fluid vessel may connect or attach to a transportation vehicle to thereby allow transportation of the fuel and CO.sub.2. Insulation may provide temperature regulation for the fuel and CO.sub.2 when positioned in the respective first and second inner compartments. One or more ports having an opening in and through the outer shell and a fluid pathway to one or more of the first inner compartment or the second inner compartment may provide fluid communication through the opening and fluid pathway for loading/offloading the fuel and/or CO.sub.2.

An apparatus and method of storing and transporting, in a dual-use cryogenic storage tank, a cryogenic liquid having a liquefaction temperature. A first pump empties the tank of a first portion of the cryogenic liquid, thereby leaving a second portion of the cryogenic liquid in the cryogenic storage tank. A second portion of the cryogenic liquid is focused at a location on a bottom of the cryogenic storage tank. Using a second pump located at the location, the cryogenic storage tank is emptied of the second portion of the cryogenic liquid, whereby a residual portion of the cryogenic liquid is left therein. Using a focused heating structure, heat may be delivered to the location to raise the temperature of the residual portion above the liquefaction temperature, thereby vaporizing all of the residual portion.

The invention relates to a pressurized gas container, in particular a gas cylinder, having an internal volume for gas storage, a fluid-distributing valve, a pressure sensor and microprocessor-based control means. The microprocessor-based control means are configured to detect filling of the gas container with gas, by comparing said at least one pressure value measured by the pressure sensor with at least one predefined and stored reference pressure threshold value; then to initiate a timer on the basis of a detection of filling of the gas container with gas; and to trigger a warning when the timer exceeds a given period calculated from the initiation of the timer.

A fluid cargo handling system with a standoff system includes a floating marine platform having an elongated first platform side, an elongated second platform side and a buoyant hull with a hull bottom. A fluid cargo transfer hose is carried on a hose reel mounted on the platform. A drive system maintains the marine platform at an offset distance from another marine platform, preventing physical contact therebetween. The drive system has at least two drive devices adjacent the first platform side and at least two drive devices adjacent the second platform side, with each of the drive devices along the first side engaging a separate driveline extending from the hull bottom adjacent the first side towards the second platform side and each of the drive devices along the second side engaging a separate driveline extending from the hull bottom adjacent the second side towards the first platform side.

A dewar for storing a cryogenic fluid includes an inner vessel, an outer vessel, and a one-piece neck tube. The outer vessel includes an outer upper jacket and an outer lower jacket configured to be joined and define an interior chamber. The inner vessel is positioned within the interior chamber so that an insulation space is defined. The insulation space is at least partially evacuated of air. The one-piece neck tube extends between the inner vessel and the central region of the outer upper jacket. The one-piece neck tube includes a first portion configured to couple with the outer upper jacket, and a second portion configured to couple with the inner vessel such that the second portion extends into the inner vessel. The second portion is integrally formed with the first portion as one-piece.

A fluid cargo handling system includes a marine manifold tower system and a floating marine platform on which is carried a liquid manifold assembly which is coupled to a cryogenic liquid transfer hose extending from the floating marine platform to the marine manifold tower system. The cryogenic liquid transfer hose is also connected to a cryogenic hose manifold assembly mounted on the marine manifold tower system. The marine manifold tower system includes an elongated tower having a first end secured to the seabed and a second end supporting the cryogenic hose manifold assembly, elevating the cryogenic hose manifold assembly above the water surface. The floating marine platform moves between a first position adjacent the marine manifold tower system and a second position, spaced apart from the marine manifold tower system, where the floating marine platform is in fluid communication with a fluid cargo transport vessel.

A fluid cargo handling system includes a quick release manifold system mounted on a floating marine platform. The quick release manifold system has a first valve in fluid communication with the first end of a first fluid transfer hose to control fluid flow within the first fluid transfer hose. A first coupler is attached to the first valve. The first coupler has a first port in fluid communication with the first valve, a second port, a purging fluid inlet and a waste fluid outlet. A drain tank is in fluid communication with the first coupler via the waste fluid outlet, and a pressurized fluid source carried is in fluid communication with the first coupler via the purging fluid inlet.

Manifold pipe assemblies and methods and systems for providing an inert atmosphere aboard cargo ships, especially cargo ships having vessels or containers that require a low oxygen environment, are provided herein. A benefit of the manifold pipe assemblies can be using pure nitrogen from a source vessel, such as a liquid nitrogen truck, to quickly and simultaneously purge multiple vessels aboard one or more cargo ships. Another benefit of the manifold pipe assemblies can be to safely adapt high pressure purge gas sources, such as liquid nitrogen trucks, for purging vessels by incorporation a pressure regulating valve and a pressure release valve.
