The use of LNG (Liquefied Natural Gas) as fuel for marine applications is increasing since it is an efficient way of cutting emissions. Within the next few decades, natural gas (NG) is expected to become the world's fastest growing major energy source. The driving forces behind this development are the depleting known oil reserves, increasing environmental care and the continuous tightening of emission restrictions. All major emissions can be significantly reduced to truly form an environmentally sound solution; the reduction in CO2, in particular, is difficult to achieve with conventional oil- based fuels. NG consists of methane (CH4) with minor concentrations of heavier hydrocarbons such as ethane and propane. In normal ambient conditions NG is a gas, but it can be liquefied by cooling it down to -162°C. In liquid form the specific volume is reduced significantly, which allows a reasonable size of storage tanks relative to energy content. The burning process of NG is clean. Its high hydrogen-to-coal ratio (the highest among the fossil fuels) means lower C02 emissions compared with oil-based fuels. When NG is liquefied, all sulphur is removed, which means zero SOX emissions. The clean burning properties of NG also significantly reduce NOX and particle emissions compared with oil-based fuels. LNG is not only an environmentally sound solution, but also economically interesting at today's oil prices.
The most feasible way of storing NG in ships is in liquid form. In existing ship installations, LNG is stored in cylindrical, double-walled, insulated stainless steel tanks. The tank pressure is defined by the requirement of the engines burning the gas and is usually less than 5 bar. A higher (typically 9 bar) tank design pressure is selected due to the natural boil-off phenomenon.
Fig. 1 discloses schematically a known LNG installation for a ship 20. LNG is stored in a cylindrically shaped pressurized storage tank 1. The tank consists of a stainless steel inner shell, which is designed for an internal pressure, and an outer shell that acts as a secondary barrier. The outer shell can be made of either stainless steel or carbon steel. The tank is insulated with perlite/vacuum. Reference numeral 24 denotes a bunkering station from which LNG is led to the tank 1 via insulated pipes. The tank room 4 is a stainless steel barrier welded to the outer vessel of the tank 1. The tank room acts as a barrier that avoids damage to the external compartments, and facilitates quick ventilation of the evaporated gas. The LNG from the tank is evaporated and fed via a gas valve unit 21 to the engines. The main engine generators are denoted by 22 and the switch gear by 23. Fig. 1 is only to show an exemplary schematic arrangement for a LNG installation and, therefore, there is no detailed explanation of a control system, thrusters, propulsion units or other necessary implements required in ships.
NG is a safe fuel when the right precautions are taken.
In a liquid state LNG is not explosive, nor is it corrosive or toxic. Thus, possible spillages will not cause any lasting contamination, as the liquid will boil to gas. The low temperature, however, is an issue when considering normal ship steel, but this problem is avoided by using appropriate materials in LNG systems.
Gaseous NG is lighter than air, which means that in case of a leakage, the gas will disperse upwards and not build up in the ship's bilge. The ignition temperature of NG is relatively high (600°C) compared with diesel oil (250°C), and NG is flammable only within a small concentration range between 5% and 15% of air. The gas fuel system of a ship includes liquid storage tanks, a vaporiser, a gas valve unit, piping and a bunkering system.
The storage tank and associated valves and piping should be located in a space designed to act as a second barrier in case of liquid or compressed gas leakage. The material of the bulkheads of this space should have the same design temperature as the gas tank, and the space should be designed to withstand the maximum pressure build-up or alternatively, pressure relief venting to a safe location (mast) may be provided. The space should be capable of containing a leakage and be thermally isolated so that the surrounding hull is not exposed to unacceptable cooling in case of a leakage of liquid or compressed gas.
The natural gas is delivered to the engines as a gas but stored as a liquid. A 'tank room' is associated with a storage tank and contains the equipment to convert the liquid into a gas for safe delivery to the engines. The tank room is also considered a 'secondary barrier' since liquid pipes are inside it.
The piping between the LNG tank and the tank room is double-walled and conventionally pipes are arranged to go through the outer shell of the LNG tank and pass into the space between the inner and outer shells of the LNG tank before they are connected to the inner shell, preferably by welding. This conventional arrangement is functional as such but it requires that the outer shell of the LNG tank is made of stainless steel since all connections to the inner shell should be inside a stainless steel cover.
An aim of the present invention is to provide an improved solution for connecting pipes to the LNG tank. This is achieved by an arrangement for connecting at least one double-walled pipe of stainless steel to a LNG tank having an inner shell of stainless steel and an outer shell spaced at a distance from the inner shell, the said inner and outer shells defining an isolation space therebetween, wherein the at least one double-walled pipe comprises a common outer wall and at least one inner pipe, wherein the outer wall of the pipe is connected to the inner shell of the tank by a pipe fitting in such a way that the pipe fitting of cold resistant material between the said inner shell and the outer wall is arranged to compensate for changes in the length of the outer wall of the pipe and/or of the pipe fitting due to temperature differences between the outer wall of the pipe and the inner shell of the tank, the pipe fitting being formed as a bellows- 1 ike structure, characterized in that at the end of the outer wall of the pipe facing the inner shell of the tank is arranged a first connection flange; that at a pipe inlet opening formed in the outer shell of the tank is formed an outwardly extending second connection flange; and that between the said first and second connection flanges is arranged a heat insulation and/or a sealing member. The bellows is preferably connected by welding to the outer wall of the pipe and to the inner shell of the tank.
By using a bellows of stainless steel as a pipe fitting between the inner shell of the LNG tank and the outer wall of the pipe it is possible to absorb relative movement in the piping system due to difference in temperature between the outer wall of the pipe and the inner shell of the tank. The materials utilized for the bellows are stainless steels, preferably austenitic type steels.
The invention will be disclosed more closely with reference to the
accompanying drawings in which:
Fig. 1 is a schematic vertical cross-section of a ship using LNG as fuel.
Fig. 2 is a schematic vertical cross-section of a part of a LNG tank and a tank room associated therewith according to an embodiment of the invention, is an enlarged view of a part of Fig. 2 showing details of the pipe penetration into the tank,
is a schematic vertical cross-section of a part of a LNG tank and a tank room associated therewith according to another embodiment of the invention, is a schematic vertical cross-section of a part of a LNG tank and a tank room associated therewith according to still another embodiment of the invention, and is a schematic vertical cross-section of a part of a LNG tank and a tank room associated therewith according to still another embodiment of the invention. Referring to Fig. 2, a LNG tank 1 comprises an inner shell 2 and an outer shell 3 defining an isolation space 14 therebetween. The isolation space 14 is under vacuum and/or filled with isolation material, such as perlite or vermiculite. A tank room 4, containing the equipment (not shown) for converting the liquid into a gas for safe delivery to the engines, is associated with the tank 1, the equipment being in fluid connection with the tank via double-walled pipes to the tank. In the schematic figs. 2 and 3 is shown two inner pipes 8 and a common outer wall 9 therefore. The inner pipes 8 are spaced apart from each others as well from the outer wall 9 defining an isolation space 15 therebetween. The isolation space 15 is, similarly to the isolation space 14 of the tank 1, under vacuum and/or filled with isolation material, such as perlite or vermiculite. At one end, the pipes 8 and the outer wall 9 penetrate the tank room and extends a length inside thereof. At its other end, the common outer wall 9 of the pipes is provided with a first connection flange 11 to which a bellows 10 is connected by welding. The bellows 10 is welded at its other end to the inner shell 2 of the tank 1. The inner pipes 8 are welded directly to the inner shell 2 of the tank. The outer shell 3 of the tank is provided with a feedthrough opening for the pipe and along the peripheral of the opening with a second connection flange 12 extending outwardly from the outer shell 3. The first and second connection flanges are aligned and provided with an isolation and/or sealing member 13 therebetween. The bellows 10 and inner pipes 8 and outer wall 9 are of cold resistant materials, preferably stainless steels, but the material for the outer shell 3 of the tank 1 may be carbon steel due to the use of the protective bellows of stainless steel around the pipe feedthrough to the inside of the tank. The use of carbon steel for the outer shell will substantially reduce the manufacturing costs.
In a further embodiment of Fig. 4 is shown an additional shell structure of carbon steel around the tank room 4 to give added stiffness and to facilitate mounting. It also gives enhanced protection for the tank room environment. In a still further embodiment of Fig. 5 is shown also an additional lower shell structure 7 of carbon steel which gives increased protection for the pipe.
Fig. 6 shows a further embodiment of the present invention. Pipe 19 for top connection is located in a pipe trunk 16 extending to the center of the tank. Pipe trunk 16 is connected to the outer shell 3 of the tank 1 via bellows 17 by a similar flange arrangement 18 as for the bellows 10 comprising flanges 11 and 12 and an isolation and/or sealing member 13 therebetween. The embodiment of Fig. 6 can be provided also with similar additional shell structures 5 and/or 7 as shown in Figs. 4 and 5. Pipe 19 and pipe trunk 16 are also of cold resistant materials, preferably stainless steels.
