Abstract:
The bilobe or multilobe tank (1) for storing liquefied natural gas comprises at least two tank sections (1a, b, 1c, 1d, 1e), each tank section (1a, 1b, 1c, 1d, 1e) having a curved upper surface and curved bottom surface, the tank sections (1a, 1b, 1c, 1d, 1e) being joined to each other so that the tank (1) has an undulating upper surface (12) and an undulating lower surface (11). Each tank section (1a, 1b, 1c, 1d, 1e) is connect- ed to an adjacent tank section (1a, 1b, 1c, 1d, 1e) with at least one horizontal connecting duct (17, 18) so that a horizontal flow path is formed between the lower- most points (13) of the adjacent tank sections (1a, 1b, c, 1d, 1e) or between the uppermost points (16) of the adjacent tank sections (1a, 1b, 1c, 1d, 1e).
Abstract:
The invention relates to an LNG tank (1) having an inner shell (2) of stainless steel and an outer shell (3) spaced at a distance from the inner shell (2), the said inner and outer shells defining an isolation space (14) therebetween. The LNG tank is provided with at least one double-walled pipe of stainless steel connected to the LNG tank (1), the said at least one double-walled pipe comprising a common outer wall (9) and at least one inner pipe (8). The outer wall (9) of the pipe is connected to the inner shell (2) of the tank by means of a bellows-like pipe fitting (10) of cold resistant material welded to the outer wall (9) of the pipe(s) and to the inner shell (2) of the tank. The said at least one double-walled pipe extends into a tank room (4) associated with the tank (1). The end of the said at least one inner pipe (8) extending into the tank room (4) is connected to a valve means in a valve block (20) and the end of the outer wall (9) of the pipe extending into the tank room is welded to the valve block (20) to provide a continuous secondary barrier for the said at least one inner pipe (8) between the inner shell (2) of the tank (1) and the valve block (20).
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). The invention also relates to a system for connecting at least one pipe between an LNG tank (10) and a tank connection space (20) thereof, which at least one pipe (16; 17) extends from the LNG tank (10) to the tank connection space (20) and which LNG tank (10) is a single-shell tank having one shell (14), wherein the at least one pipe (16; 17) is connected between the LNG tank (10) and the tank connection space (20) by at least one bellow connection (11; 12).
Abstract:
Invention relates a cryogenic tank arrangement (10) comprising a tank body (12) enclosing a storage space (16) for storing liquefied gas, the tank arrangement having a safety valve arrangement (25) in which at least one pressure relief valve (26) is directly connected to the storage space (16) of the tank body (12).There is a pressure relief valve (26) arranged directly connected to at least two locations (24', 24") on a same face (22') of the tank body.
Abstract:
A fuel storage and delivery system for a gas-fuelled sea-going vessel comprises an evaporator for vaporizing liquid gas. A tank room constitutes a gas-tight enclosure, in which said evaporator is located. An airlock constitutes an access to said tank room.
Abstract:
A fuel storage and delivery system for a sea-going vessel comprises an evap- orator for vaporizing liquid gas or a pressure reducing valve, and an engine- specific fuel input subsystem for delivering vaporized gas from said evaporator or pressure reducing valve to an engine of said sea-going vessel. A tank room constitutes a gastight enclosure, in which said evaporator or pressure reducing valve is located. Said fuel input subsystem is also located inside said tank room.
