Description
Die Erfindung betrifft eine Vorrichtung zur Lagerung eines unabhängigen Tankes für Flüssiggas, insbesondere LNG, in einem Schiff nach dem Oberbegriff des Anspruches 1, sowie einen für die Vorrichtung besonders geeigneten biloben Drucktank.The The invention relates to a device for storing an independent tank for liquefied gas, in particular LNG, in a ship according to the preamble of claim 1, as well as one for the device particularly suitable biloben pressure tank.
Für den Transport von Flüssiggas in Schiffen, namentlich hochseegehenden Schiffen, gibt es traditionell mehrere Lösungen. In jedem Fall geht es darum, einen Behälter für das kalte oder tiefkalte Flüssiggas in dem Schiff gegenüber der Schiffshülle thermisch zu isolieren und gleichzeitig eine Verbindung des Behälters mit der Schiffshülle zu schaffen, die der Last der Beladung und den bei der Fahrt auftretenden Beschleunigungen von bis zu 1,5 g standhält. Neben Integraltanks, Membrantanks und Semi-Membrantanks werden unabhängige Tanks für das Flüssiggas eingesetzt, die in sich selbst, d.h. ohne Rückgriff auf die Schiffskonstruktion mechanisch stabil sind. Dabei wird weiter zwischen drucklosen Tanks und Drucktanks unterschieden, wobei die Temperatur des Flüssiggases im drucklosen Tank naturgemäß besonders niedrig ist.For the transport of liquefied gas In ships, especially ships going deep-sea, there is tradition several solutions. In any case, it is about a container for the cold or cryogenic LPG in the ship opposite the hull of the ship thermally to isolate and at the same time connect the container with the ship hull to create the load of the load and the occurring during the journey Accelerations of up to 1.5 g can withstand. In addition to integral tanks, membrane tanks and semi-membrane tanks become independent tanks for liquefied natural gas used in themselves, i. without recourse to the ship's construction mechanically stable. It will continue between unpressurized tanks and pressure tanks distinguished, the temperature of the liquefied gas in the pressureless tank naturally especially is low.
Flüssiges Erdgas (LNG) stellt dabei besondere Anforderungen an die Konstruktion, weil seine Temperatur niedriger als die der meisten technischen Flüssiggase ist.Liquid natural gas (LNG) makes special demands on the construction, because its temperature is lower than that of most technical liquefied gases is.
Es sind bereits Schiffe für den Transport von Flüssiggas mit einer Vorrichtung der eingangs genannten Art gebaut worden, bei welchen der Tank kreiszylindrisch ist und mit seiner Längsachse in Längsrichtung, gelegentlich auch in Querrichtung des Schiffes liegt. Dabei bilden das an der Schiffshülle befestigte Fundament und der dem kreiszylindrischen Tank angepaßte, in etwa kreisabschnittförmige Sattel eine bauliche Einheit und die Isolierschicht ist zwischen Sattel und Tank angeordnet. An einem der beiden Sättel ist der Tank gegenüber Längsverschiebungen gesichert, jedoch am anderen Sattel gegenüber diesem in Längsrichtung beweglich, so daß keine thermischen Spannungen in Längsrichtung entstehen können. Quer zur Längsrichtung wird der Tank festgehalten, weil er formschlüssig im Sattel liegt. Die thermische Schrumpfung in dieser Richtung erfolgt aber zum tiefsten Punkt im Sattelfundament, weshalb auch insoweit keine signifikanten thermischen Spannungen auftreten.It are already ships for the transport of liquefied gas been built with a device of the type mentioned, in which the tank is circular cylindrical and with its longitudinal axis longitudinal, occasionally also in the transverse direction of the ship. Make up that on the hull fixed foundation and the circular cylindrical tank adapted, in approximately circular segmented saddle a structural unit and the insulating layer is between saddle and tank arranged. On one of the two saddles, the tank is opposite longitudinal displacements secured, but on the other saddle opposite this in the longitudinal direction movable, so that no thermal stresses in the longitudinal direction can arise. Transverse to the longitudinal direction the tank is held in place because it lies in the saddle with a positive fit. The thermal Shrinkage in this direction occurs but to the lowest point in the Saddle foundation, which is why so far no significant thermal Tensions occur.
Das letztere trifft nicht zu für sogenannte bilobe Tanks, die die Form zweier paralleler und ineinander verschnittener Kreiszylinder haben. Solche biloben Tanks werden seit einiger Zeit eingesetzt, weil sie den Schiffsraum effizienter als kreiszylindrische Tanks nutzen und gleichzeitig deren Vorteile hinsichtlich der mechanischen Stabilität bewahren. Zur Lagerung bilober Tanks in Schiffen sind Vorrichtungen der zuvor beschriebenen Bauweise mit gemeinsamen Sätteln für beide Tankhälften schon verwendet worden. Entsprechend der Tankform haben diese Sättel die Gestalt zweier in Querrichtung des Tankes aneinander anschließender Kreisabschnitte. Die thermische Schrumpfung in Querrichtung erfolgt hier zur Mitte des Sattels auf seinen höchsten Punkt mit der Folge, daß thermische Spannungen entstehen. Diese sind gerade noch akzeptabel, wenn es sich um ein relativ hoch siedendes Flüssiggas, z.B. Ethylen (Ladungstemperatur ca. –100°C) handelt. Bei niedrigeren Temperaturen, wie sie z.B. bei flüssigem Erdgas auftreten, stößt die bekannte Konstruktion an ihre Grenzen, und zwar wegen der Temperaturen selber und zusätzlich wegen des höheren Wärmedehnungskoeffizienten des Tank-Werkstoffes, der für tiefkalte Flüssiggase eingesetzt werden muß.The the latter is not true for so-called bilobe tanks, which are the shape of two parallel and one inside the other have cut circular cylinder. Such biloben tanks will be used for some time because they make the ship's space more efficient to use as a circular cylindrical tanks and at the same time their advantages with regard to mechanical stability. For storage bilober Tanks in ships are devices of the construction described above with common saddles for both tank halves already been used. According to the tank shape, these saddles have the Shape of two adjacent in the transverse direction of the tank circular sections. The thermal shrinkage in the transverse direction takes place here to the middle of the saddle on its highest Point with the consequence that thermal Tensions arise. These are just acceptable if it is is a relatively high boiling liquefied petroleum gas, e.g. Ethylene (charge temperature about -100 ° C) is. At lower temperatures, e.g. occur in liquid natural gas, pushes the familiar Construction to its limits, because of the temperatures themselves and additionally because of the higher Thermal expansion coefficient of the tank material used for cryogenic liquefied gases must be used.
Der Erfindung liegt die Aufgabe zugrunde, eine Vorrichtung der eingangs genannten Art zu schaffen, die nicht nur für kreiszylindrische, sondern auch für bilobe Tanks geeignet ist, die mit besonders kalten, sog. tiefkalten Flüssiggasen, insbesondere LNG, befüllt werden sollen.Of the Invention is the object of a device of the initially mentioned type, not only for circular cylindrical, but also for bilobe Tanks with particularly cold, so-called cryogenic liquid gases, especially LNG, filled should be.
Diese Aufgabe ist erfindungsgemäß mit der in Anspruch 1 gekennzeichneten Vorrichtung gelöst, wobei vorteilhafte Ausgestaltungen aus den Unteransprüchen hervorgehen. Ein an die erfindungsgemäße Vorrichtung besonders angepaßter bilober Drucktank gemäß der Erfindung ist in Anspruch 10 gekennzeichnet.These Task is inventively with in Claim 1 characterized device solved, wherein advantageous embodiments from the dependent claims emerge. An especially adapted to the device according to the invention bilober Pressure tank according to the invention is characterized in claim 10.
Bei der erfindungsgemäßen Vorrichtung bilden Fundament und Sattel keine bauliche Einheit. Vielmehr sind beide voneinander getrennt und haben zwei zueinander parallele ebene Flächen, zwischen denen die dementsprechend ebenfalls ebene thermische Isolierschicht liegt. An dieser oder auch, bei zweiteiliger Ausbildung der Isolierschicht mit zwei ebenen Grenzflächen, innerhalb dieser können nun Relativbewegungen zum Ausgleich thermischer Spannungen in allen Richtungen, also gerade auch quer zur Längsrichtung des Tankes stattfinden, so daß es für das Funktionieren der Konstruktion auf die Querschnitts-Gestalt des Tankes und, weil die Spannungen nicht aufgefangen, sondern abgebaut werden, auf eine Mindesttemperatur des Flüssiggases nicht mehr ankommt. Die erfindungsgemäße Vorrichtung ist deshalb insbesondere prädestiniert zur Lagerung von biloben Tanks für den Transport von LNG.at the device according to the invention Foundation and saddle do not form a structural unit. Rather, they are both separated and have two mutually parallel plane surfaces, between which the accordingly also level thermal insulation layer lies. At this or even, in two-part formation of the insulating layer with two plane interfaces, within this can now relative movements to compensate for thermal stresses in all Directions, ie also take place transversely to the longitudinal direction of the tank, so that it for the Functioning of the construction on the cross-sectional shape of the Tankes and, because the tensions are not absorbed, but dismantled be, on a minimum temperature of the liquefied gas no longer arrives. The device according to the invention is therefore predestined in particular for storage of biloben tanks for the transport of LNG.
Die Isolierschichten der erfindungsgemäßen Vorrichtung bestehen vorzugsweise aus einem druck- und schubfesten Material, damit sie nicht nur der Last des gefüllten Tankes, sondern auch den Reibungskräften standhalten können, die bei temperaturdifferenzbedingten Relativbewegungen eingeleitet werden. Das Material kann ein polymerer Kunststoff sein. Vorzugsweise kommt jedoch in an sich bekannter Weise Pressholz zum Einsatz. Die Isolierschichten können fest an der Oberseite des Fundamentes oder fest an der Unterseite des zugeordneten Sattels angebracht sein. Im Falle zweiteiliger Isolierschichten ist ein Teil an der Oberseite des Fundaments und der andere Teil an der Unterseite des zugeordneten Sattels fest angebracht, womit die Relativbewegung zwischen beiden innerhalb der Isolierschicht an den ebenen Grenzflächen der beiden Teile stattfindet.The insulating layers of the device according to the invention are preferably made of a pressure and shear-resistant material, so that they can withstand not only the load of the filled tank, but also the frictional forces, which are initiated at relative temperature-induced relative movements. The material may be a polymeric plastic. Preferably, however, is known per se The way Pressholz used. The insulating layers may be fixedly attached to the top of the foundation or fixed to the underside of the associated saddle. In the case of two-part insulating layers, one part is fixedly attached to the upper side of the foundation and the other part to the lower side of the associated saddle, whereby the relative movement between the two takes place within the insulating layer at the flat boundary surfaces of the two parts.
Erfindungsgemäß bevorzugt wird die erste Alternative, bei der jede Isolierschicht an der Oberseite ihres Fundamentes fest angebracht ist, so daß die Relativbewegung zwischen Sattel und Fundament an der Unterseite des Sattels stattfindet. Das ist konstruktiv am einfachsten.According to the invention preferred The first alternative is where each insulating layer is at the top its foundation is firmly attached, so that the relative movement between Saddle and foundation takes place at the bottom of the saddle. That is the simplest way of constructing.
Bei dieser Ausbildung erfolgt die Halterung des Tankes im Schiff zur Vermeidung von Verschiebungen insgesamt am besten mit den Mitteln des Anspruchs 4, bei welchem die Stege Gleitbewegungen zwischen der Unterseite der Sättel und der am Fundament festgehaltenen Isolierschicht jeweils quer zur ihrer Längserstreckung unterbinden. Natürlich ist dabei Auswahl und Anordnung der Stege so zu wählen, daß der Abbau thermischer Spannungen nicht eingeschränkt wird. Eine bevorzugte Anordnung insoweit geht aus den Ansprüchen 5 und 6 hervor. Der mindestens eine Steg, der sich in Tankquerrichtung an einem Sattel erstreckt, verhindert die Bewegung des Tankes an diesem Sattel in Längsrichtung. An dem oder den anderen Sätteln gibt es dagegen keinen quer verlaufenden Steg, so daß dort die notwendige Relativbewegung zum Abbau zum Spannungen in Längsrichtung möglich ist. In Querrichtung sichern den Tank die längslaufenden Stege gemäß Anspruch 6, lassen aber symmetrisch zu ihren beiden Seiten die Relativbewegungen in Querrichtung zu, die hier zum Abbau der thermischen Spannungen notwendig sind. Liegt der Tank mit seiner Längsachse parallel zur Schiffslängsrichtung, der üblichen und bevorzugten Anordnung, sollen sich die längslaufenden Stege genau in der Mitte des Schiffes, bezogen auf seine Querrichtung, befinden, damit der Tank bei einer allfälligen Dehnung oder Schrumpfung in Bezug auf das Schiff zentriert bleibt und somit dessen Trimmung nicht gestört wird.at This training is the holder of the tank in the ship for Avoiding shifts altogether best with the means of claim 4, wherein the webs sliding movements between the underside of the saddles and the insulating layer held on the foundation each transverse to their longitudinal extent prevention. Naturally is to choose the selection and arrangement of the webs so that the degradation thermal stresses is not restricted. A preferred arrangement insofar goes from the claims 5 and 6 show. The at least one bridge, which is in tank transverse direction extends on a saddle, prevents the movement of the tank on this saddle in the longitudinal direction. On one or the other saddles on the other hand, there is no transverse bridge so that there necessary relative movement to reduce the tension in the longitudinal direction possible is. In the transverse direction, the tank secure the longitudinal webs according to claim 6, but leave symmetrical to their two sides, the relative movements in the transverse direction, here to reduce the thermal stresses necessary. Is the tank with its longitudinal axis parallel to the ship's longitudinal direction, the usual and preferred arrangement, should the longitudinal webs exactly in the center of the ship in relation to its transverse direction, so that the tank in a possible Elongation or shrinkage in relation to the ship remains centered and thus its trim is not disturbed.
Die Sicherungen, die bei Seegang das Abheben des Tankes von den Fundamenten unterbinden, sind vorzugsweise gemäß Anspruch 7 ausgestaltet. Sie sind ebenfalls in der Quer-Mitte des Schiffes angeordnet. Dies hat gegenüber einer denkbaren Anordnung an beiden Seiten des Tankes den Vorteil, daß es bei der Entladung des Tankes nicht zu Verklemmungen zwischen Tank und Schiffshülle kommt aufgrund einer leichten konkaven Einwölbung des Schiffsbodens, die bei der Entladung in der Tat eintritt.The Fuses that in swell the lifting of the tank from the foundations Prevent, are preferably designed according to claim 7. she are also arranged in the transverse center of the ship. this has across from a conceivable arrangement on both sides of the tank the advantage that it at the discharge of the tank does not cause jamming between tank and hull comes due to a slight concave concavity of the ship's bottom, the when discharging indeed occurs.
Selbstverständlich können in einem Schiff mehrere Tanks jeweils mit Hilfe einer erfindungsgemäßen Vorrichtung gelagert sein. Die Auslegung des Schiffes insoweit richtet sich nach üblichen, bekannten Kriterien. Ebenso ist es natürlich möglich, einen erfindungsgemäß gelagerten Tank im Bedarfsfall auch mit anderen flüssigen Medien, z.B. Chemikalien zu befüllen, um eine wirtschaftliche Nutzung des Schiffes sicherzustellen.Of course, in a ship several tanks each using a device according to the invention be stored. The design of the ship in this respect is directed according to usual, known criteria. Likewise, it is of course possible, an inventively stored Tank also, if necessary, with other liquid media, e.g. Chemicals too fill, to ensure economic use of the ship.
