Abstract:
The invention relates to a fuel tank arrangement (10) comprising a tank container (12) for liquefied gas in a marine vessel (16), which is arranged to endure internal pressure above the atmospheric pressure and which is provided with heat insulation on outer surface of the container, and the tank when containing liquefied gas in use includes a liquefied gas space and an ullage space, and in which arrangement a communication junction for liquefied gas is arranged to communicate with the inner space of the container. The communication junction (40,41) is arranged to serve as a coupling means for gas lines (27,28) of the arrangement, and that the communication junction is connected to the tank container.
Abstract:
Invention relates an arrangement for transferring liquefied gas from a cryogenic tank (11 ) comprising an intake passage (16) extending into the tank (11 ), a pump (18) arranged in connection with the intake passage (16) such that liquefied gas can be transferred from the cryogenic tank (11 ) into the intake passage (16) when the pump (18) is operated, wherein the intake passage (16) is provided with at least two inlet openings (22) arranged at different locations (L1...LN) of the intake passage (16), at least one of the inlet openings (22) is provided with a flow control means (24) configured to adjust the flow resistance of the inlet opening (22). Invention relates also to a method of transferring liquefied gas from a cryogenic tank (11 ).
Abstract:
The invention relates to an LNG tank (10) located in a tank hold space (16) of a marine vessel comprising an inner metal shell (11), an outer metal shell (12) and an isolation space (13) between the shells (11, 12) advantageously con- taining vacuum, which LNG tank (10) further comprises an insulation material (15) adhered on outer surface (14) of the outer metal shell (12).
Abstract:
The invention relates to an LNG tank, which LNG tank (10) is a single-shell LNG tank having one shell (14) and which LNG tank (10) comprises at least one pipe (16; 17) extending from the LNG tank (10) to a tank connection space (20) of the LNG tank (10), wherein the shell (14) of the LNG tank (10) is sub- stantially surrounded by insulation (13) and that the LNG tank (10) comprises at least one bellow connection (11; 12) sur- rounding at least part of the length of the at least one pipe (16, 7) for connecting the at least one pipe (16; 17) extending from the LNG tank (10) to the tank connection space (20).

Abstract:
The invention relates method of filling a fuel tank (12) with liquefied gas, in which method liquefied gas is brought into the tank so that gas in introduced to a lower section (12.1) of the tank below the surface of the liquefied gas in the tank, and during a first phase of the filling procedure while gas in introduced to a lower section of the tank the pressure of the tank is maintained below a predetermined set pressure by spraying of liquefied gas into a gas space in the upper section (12.2) of the tank above the surface of the liquefied gas in the tank. In the method at a predetermined state of the filling procedure a second phase of the procedure is initiated during which the spraying liquefied gas into a gas space in the upper section (12.2) of the tank is decreased and the second phase is practised until a predetermined filling stage of the tank is reached to fuel (14.1).
