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 biloben Drucktank, an dem die erfindungsgemäße Vorrichtung verwirklicht ist.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 a biloben pressure tank on which the device according to the invention is realized.

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.There are traditionally several solutions for the transport of liquefied gas in ships, in particular seagoing ships. In any case, it is a matter of thermally insulating a container for the cold or cryogenic LPG in the ship against the hull and at the same time to create a connection of the container with the hull, the load of the load and the accelerations occurring during the trip from to withstands 1.5 g. In addition to integral tanks, membrane tanks and semi-membrane tanks, independent tanks are used for the liquefied petroleum gas, which in themselves, i. are mechanically stable without resorting to the ship's design. It is further distinguished between pressureless tanks and pressure tanks, the temperature of the liquefied gas in the pressureless tank is naturally very 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) places special demands on the design because its temperature is lower than that of most technical liquefied gases.

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, vgl. z. B. GB-A-2032087 . 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.There have already been built ships for the transport of liquefied gas with a device of the type mentioned, in which the tank is a circular cylinder and with its longitudinal axis in the longitudinal direction, occasionally also in the transverse direction of the ship, cf. z. B. GB-A-2032087 , In this case, the foundation attached to the hull and the circular cylindrical tank adapted, approximately circular section saddle form a structural unit and the insulating layer is disposed between the saddle and the tank. On one of the two saddles is the tank opposite Secured longitudinal displacements, but on the other saddle relative to this longitudinally movable, so that no thermal stresses can occur in the longitudinal direction. Transverse to the longitudinal direction of the tank is held, because it is form-fitting in the saddle. The thermal shrinkage in this direction, however, takes place at the lowest point in the saddle foundation, which is why no significant thermal stresses occur to that extent.

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 latter does not apply to so-called bilobe tanks, which have the shape of two parallel and intersecting circular cylinders. Such biloben tanks have been used for some time, because they use the space more efficient than circular cylindrical tanks while preserving their advantages in terms of mechanical stability. For storage bilober tanks in ships devices of the construction described above with common saddles for both tank halves have 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 to its highest point, with the result that thermal stresses arise. These are just acceptable if it 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 known construction to its limits, and because of the temperatures themselves and additionally because of the higher thermal expansion coefficient of the tank material, which must be used for cryogenic liquefied gases.

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.The invention has for its object to provide a device of the type mentioned, which is not only suitable for circular cylindrical, but also for bilobe tanks that are to be filled with particularly cold, so-called. Tiefkalten liquid gases, especially LNG.

Diese Aufgabe ist erfindungsgemäß mit der in Anspruch 1 gekennzeichneten Vorrichtung gelöst, wobei vorteilhafte Ausgestaltungen aus den Unteransprüchen hervorgehen. Ein mit der erfindungsgemäßen Vorrichtung ausgebildeter bilober Drucktank ist in Anspruch 9 gekennzeichnet.This object is achieved according to the invention with the characterized in claim 1 Device solved, with advantageous embodiments emerge from the dependent claims. A trained with the device according to the invention bilober pressure tank is characterized in claim 9.

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.In the inventive device foundation and saddle form no structural unit. Rather, both are separated from each other and have two mutually parallel planar surfaces, between which the accordingly also level thermal insulation layer is located. At this or even, in two-part formation of the insulating layer with two flat boundary surfaces, within this relative movements can now take place to compensate for thermal stresses in all directions, ie just transverse to the longitudinal direction of the tank, so that it for the functioning of the construction on the cross-sectional Shape of the tank and, because the tensions are not collected, but reduced, no longer reaches a minimum temperature of the liquefied gas. The device according to the invention is therefore particularly predestined for the storage of biloben tanks for the transport of LNG.

Aus der FR-A-2710310 war bereits eine Vorrichtung zur Lagerung eines biloben Tankes für Flüssiggas einschließlich LNG in einem Schiff bekannt, bei welcher Sättel unmittelbar am Tank befestigt sind und jeweils eine ebene Unterseite aufweisen, die auf ebenso ebenen Oberseiten von Fundamenten aufliegen und auf diesen gleiten können. Jedoch hat bei dieser Vorrichtung, bezogen auf einen Querschnitt durch den Tank, jede Tankhälfte ein eigenes Fundament, dessen Oberseite zu der des benachbarten Fundamentes an der anderen Tankhälfte, im Querschnitt gesehen, V-förmig geneigt ist. Das lässt thermische Spannungen genauso entstehen wie bei der zuvor beschriebenen Vorrichtung mit gemeinsamen Sätteln für beide Tankhälften in Gestalt zweier aneinander anschließender Kreisabschnitte. Hinzu kommt, dass keine thermische Isolierung der Fundamente gegenüber dem Tank vorgesehen und nichts offenbart ist über die Ausbildung etwaiger Sicherungen zur Halterung des Tanks auf den Fundamenten.From the FR-A-2710310 Was already a device for storage of a biloben tank for liquefied gas including LNG in a ship known in which saddles are attached directly to the tank and each having a flat bottom, which rest on equally flat tops of foundations and can slide on this. However, in this apparatus, with respect to a cross-section through the tank, each tank half has its own foundation, whose top to that of the adjacent foundation on the other tank half, seen in cross section, is V-shaped inclined. This causes thermal stresses to arise in the same way as in the device described above with common saddles for both tank halves in the form of two adjoining circular sections. In addition, no thermal insulation of the foundations provided with respect to the tank and nothing is disclosed on the formation of any fuses for holding the tank on the foundations.

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 preferably consist 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 used in a conventional manner compressed wood 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, preference is given to the first alternative, in which each insulating layer is firmly attached to the top of its foundation so that the relative movement between the saddle and the foundation takes place on the underside 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.In this embodiment, the holder of the tank in the ship to avoid shifts is generally best done with the means of claim 4, wherein the webs prevent sliding movements between the underside of the saddles and the insulating layer held on the foundation each transverse to their longitudinal extent. Of course, the choice and arrangement of the webs should be chosen so that the degradation of thermal stresses is not restricted. A preferred arrangement in this respect is apparent from the claims 5 and 6. The at least one web extending in tank transverse direction on a saddle, prevents the movement of the tank on this saddle in the longitudinal direction. On the other saddles or on the other hand, there is no transverse web, so that there the necessary relative movement to reduce the tension in the longitudinal direction is possible. In the transverse direction, the tank secure the longitudinal webs according to claim 6, but allow symmetrical to its two sides, the relative movements in the transverse direction, which are necessary here to reduce the thermal stresses. If the tank with its longitudinal axis is parallel to the ship's longitudinal direction, the usual and preferred arrangement, the longitudinal webs should be exactly in the middle of the vessel, with respect to its transverse direction, so that the tank centers in the event of any stretching or shrinkage in relation to the ship remains 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, which prevent the lifting of the tank from the foundations in rough seas, are preferably designed according to claim 7. They are also located in the transverse center of the ship. This has over a conceivable arrangement on both sides of the tank the advantage that it at The discharge of the tank does not lead to jamming between the tank and the hull due to a slight concave curvature of the ship's bottom, which actually occurs during unloading.

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, several tanks can be stored in each case by means of a device according to the invention in a ship. The design of the ship in this respect depends on customary, known criteria. Likewise, it is of course possible, if necessary, a tank according to the invention also with other liquid media, e.g. To fill chemicals to ensure the economic exploitation of the ship.

Im Folgenden ist die Erfindung mit weiteren vorteilhaften Einzelheiten an Hand eines schematisch dargestellten Ausführungsbeispiels näher erläutert.In the following, the invention is explained in more detail with further advantageous details with reference to a schematically illustrated embodiment.

Fig. 1 zeigt einen vereinfachten Querschnitt durch einen Schiffsrumpf 1 mit einer erfindungsgemäßen Vorrichtung zur Lagerung eines biloben Tanks 3. Die dargestellte Schnittebene ist senkrecht zur Schiffslängsachse. Fig. 1 shows a simplified cross-section through a ship's hull 1 with an inventive device for supporting a biloben tank 3. The illustrated section plane is perpendicular to the ship's longitudinal axis.

Der bilobe Tank 3 weist einen Querschnitt auf, der aus zwei Kreisbogensegmenten besteht. Der Tank 3 ruht auf zwei oder mehr Sätteln 6, von denen in Fig. 1 einer dargestellt ist. Der Sattel 6 ist mit dem Tank 3 fest verbunden, vorzugsweise verschweißt. Ein Fundament 4 ist im Schiffsrumpf 1 angeordnet und mit diesem fest verbunden. Zwischen einer ebenen Oberseite 5 des Fundaments 4 und einer ebenen Unterseite 7 des Sattels 6 ist eine Isolierschicht 8 angeordnet. Die Isolierschicht 8 überträgt die Gewichtskraft des Tanks 3 und seines Inhalts auf das Fundament 4. Die Isolierschicht 8 besteht vorzugsweise mindestens zum Teil aus Pressholz. Sie ist mit der ebenen Unterseite 7 des Sattels 6 fest verbunden und gleitet auf der ebenen Oberseite 5 des Fundaments 4. Alternativ ist die Isolierschicht 8 mit der ebenen Oberseite 5 des Fundaments 4 fest verbunden und gleitet auf der ebenen Unterseite 7 des Sattels 6. Gemäß einer weiteren Alternative besteht die Isolierschicht 8 aus zwei oder mehr Schichten, von denen die unterste mit der ebenen Oberseite 5 des Fundaments 4 und die oberste mit der ebenen Unterseite 7 des Sattels 6 fest verbunden sind.The bilobe tank 3 has a cross-section consisting of two circular arc segments. The tank 3 rests on two or more saddles 6, of which in Fig. 1 one is shown. The saddle 6 is fixedly connected to the tank 3, preferably welded. A foundation 4 is arranged in the hull 1 and firmly connected with this. Between a flat top 5 of the foundation 4 and a flat bottom 7 of the saddle 6, an insulating layer 8 is arranged. The insulating layer 8 transmits the weight of the tank 3 and its contents to the foundation 4. The insulating layer 8 preferably consists at least in part of compressed wood. It is firmly connected to the flat bottom 7 of the saddle 6 and slides on the flat top 5 of the foundation 4. Alternatively, the insulating layer 8 is fixedly connected to the flat top 5 of the foundation 4 and slides on the flat bottom 7 of the saddle 6. According In a further alternative, the insulating layer 8 consists of two or more layers, of which the lowermost with the flat top 5 of the foundation 4 and the top with the flat bottom 7 of the saddle 6 are firmly connected.

In Fig. 1 und in den nachfolgenden Figuren nicht dargestellt ist eine Isolierhülle des Tanks 3. Diese umgibt den Tank 3 und den Sattel 6 allseitig mit Ausnahme der ebenen Unterseite 7 des Sattels 6, der von der in Fig. 1 dargestellten Isolierschicht 8 bedeckt ist. Die nicht dargestellte Isolierhülle und die Isolierschicht 8 minimieren den Kälteverlust des Tanks 3 bzw. den Übergang von Wärme vom Schiffsrumpf 1 auf den Tank 3.In Fig. 1 and in the following figures is not shown an insulating shell of the tank 3. This surrounds the tank 3 and the saddle 6 on all sides except the flat bottom 7 of the saddle 6, of the in Fig. 1 illustrated insulating layer 8 is covered. The insulation, not shown, and the insulating layer 8 minimize the loss of cold of the tank 3 and the transition of heat from the hull 1 to the tank. 3

Parallel zur Isolierschicht 8 wirkenden Quer- oder Längskräfte treten unter Anderem statisch bei Krängung des Schiffes und dynamisch beim Rollen, Nicken oder Gieren des Schiffes auf. Diese parallel zur ebenen Oberseite 5 des Fundaments 4 und zur ebenen Unterseite 7 des Sattels 6 werden durch Einrichtungen übertragen, die unten anhand der weiteren Fig. 2 bis 8 näher beschrieben werden. Von diesen Einrichtungen sind in Fig. 1 eine Konsole 14 und eine Abstützung 15 erkennbar.Transverse or longitudinal forces acting parallel to the insulating layer 8, inter alia, occur statically when the ship is slung and dynamically when the ship rolls, nods or yaws on. These parallel to the flat top 5 of the foundation 4 and the flat bottom 7 of the saddle 6 are transmitted by means of the below with reference to the other Fig. 2 to 8 be described in more detail. Of these facilities are in Fig. 1 a console 14 and a support 15 recognizable.

Fig. 2 zeigt in schematischer Weise eine Seitenansicht des Tanks 3 mit seiner erfindungsgemäßen Lagerung. Vorzugsweise ist die in Fig. 2 dargestellte Lagerung die in Fahrtrichtung hintere oder hinterste von zwei oder mehr Lagerungen. An dem Tank 3 ist der Sattel 6 angebracht. Zwischen der ebenen Unterseite 7 des Sattels 6 und der ebenen Oberseite 5 des Fundaments 4 ist die Isolierschicht 8 angeordnet. In Längsrichtung des Schiffes vor und hinter dem Sattel 6 sind Abstützungen 15 mit dem Fundament 4 fest verbunden. Diese umschließen, wie unten mit Bezug auf die Fig. 6 und 7 näher erläutert wird, die mit dem Sattel 6 fest verbundenen Konsolen 14. Die Konsolen 14 sind vorzugsweise Fortsetzungen der die ebene Unterseite 7 des Sattels 6 bildenden Platte. Fig. 2 shows in a schematic way a side view of the tank 3 with its storage according to the invention. Preferably, the in Fig. 2 illustrated storage in the direction of travel rear or rearmost of two or more bearings. At the tank 3, the saddle 6 is attached. Between the flat bottom 7 of the saddle 6 and the flat top 5 of the foundation 4, the insulating layer 8 is arranged. In the longitudinal direction of the ship in front of and behind the saddle 6 supports 15 are fixedly connected to the foundation 4. These enclose as below with respect to the 6 and 7 The brackets 14 are preferably continuations of the flat bottom 7 of the saddle 6 forming plate.

Ein Steg 10 ist senkrecht zur ebenen Unterseite 7 des Sattels 6 angeordnet und mit diesem fest verbunden. Der Steg 10 ist quer zur Längsachse des Schiffes angeordnet und greift in eine entsprechende Ausnehmung 11 der Isolierschicht 8, die mit der ebenen Oberseite 5 des Fundaments 4 fest verbunden ist. Über den Steg 10 und die Isolierschicht 8 bzw. die Ausnehmung darin, werden durch Formschluss Kräfte parallel zur Schiffslängsachse zwischen dem Fundament 4 und dem Sattel 6 übertragen.A web 10 is perpendicular to the flat bottom 7 of the saddle 6 and fixedly connected thereto. The web 10 is arranged transversely to the longitudinal axis of the ship and engages in a corresponding recess 11 of the insulating layer 8, which is firmly connected to the flat top 5 of the foundation 4. Over the web 10 and the insulating layer 8 and the recess therein, forces are transmitted parallel to the ship's longitudinal axis between the foundation 4 and the saddle 6 by positive engagement.

Fig. 3 zeigt schematisch eine Seitenansicht einer weiteren Lagerung des Tanks 3 im Schiffsrumpf 1. Vorzugsweise sind die in Fig. 2 dargestellte Lagerung in Fahrtrichtung des Schiffes hinten am Tank 3 und die in Fig. 3 dargestellte Lagerung in Fahrtrichtung des Schiffes vorne am Tank 3 angeordnet. Die in Fig. 3 dargestellte Lagerung unterscheidet sich von der in Fig. 2 dargestellten Lagerung dadurch, dass kein Steg 10 an der ebenen Unterseite 7 des Sattels 6 vorgesehen ist. Eine Übertragung von Kräften in Längsrichtung des Schiffes zwischen dem Tank 3 und dem Sattel 6 einerseits und dem Fundament 4 andererseits erfolgt somit nicht. Aus Temperaturänderungen resultierende Änderungen der Länge des Tanks 3 und insbesondere des Abstandes der Sättel 6 haben deshalb keine Spannungen zwischen dem Sattel 6 und dem Fundament 4 zur Folge. Fig. 3 schematically shows a side view of a further storage of the tank 3 in the hull 1. Preferably, the in Fig. 2 illustrated storage in the direction of travel of the ship at the rear of the tank 3 and in Fig. 3 shown storage in the direction of travel of the ship front of the tank 3 arranged. In the Fig. 3 shown storage is different from the one in Fig. 2 shown storage by the fact that no web 10 is provided on the flat bottom 7 of the saddle 6. A Transmission of forces in the longitudinal direction of the vessel between the tank 3 and the saddle 6 on the one hand and the foundation 4 on the other hand is thus not. Changes in the length of the tank 3 and in particular the spacing of the saddles 6 resulting from temperature changes therefore do not result in any stresses between the saddle 6 and the foundation 4.

Fig. 4 zeigt in schematischer Weise einen Ausschnitt der in Fig. 2 gezeigten Lagerung in vergrößerter Darstellung. Die Isolierschicht 8 ist durch eine trogförmige Ausgestaltung des Fundaments 4 oder auch durch andere Maßnahmen gegen eine Verschiebung relativ zum Fundament 4 in Quer- oder Längsrichtung des Schiffes 10 gesichert. Der Steg 10 an der ebenen Unterseite 7 des Sattels 6 greift in die entsprechende Ausnehmung 11 in der Isolierschicht 8. In Längsrichtung des Schiffes vor und hinter dem Sattel 6 schließt sich die in den Fig. 1 bis 3 nicht dargestellte Isolierhülle des Tanks 3 an den Sattel 6 an. Fig. 4 schematically shows a section of the in Fig. 2 shown storage in an enlarged view. The insulating layer 8 is secured by a trough-shaped configuration of the foundation 4 or by other measures against displacement relative to the foundation 4 in the transverse or longitudinal direction of the vessel 10. The web 10 on the flat bottom 7 of the saddle 6 engages in the corresponding recess 11 in the insulating layer 8. In the longitudinal direction of the ship in front of and behind the saddle 6 closes in the Fig. 1 to 3 Not shown insulating shell of the tank 3 to the saddle 6.

Fig. 5 zeigt in schematischer Weise einen Ausschnitt der in Fig. 3 gezeigten Lagerung in vergrößerter Darstellung. Im Unterschied zu der in den Fig. 2 und 4 dargestellten Lagerung ist bei der in den Fig. 3 und 5 gezeigten Lagerung kein Steg 10 an der ebenen Unterseite 7 des Sattels 6 angeordnet. Die ebene Unterseite 7 des Sattels 6 kann deshalb auf der Isolierschicht 8 gleiten. Zwischen dem Sattel 6 und dem Fundament 4 werden keine oder zumindest keine die Reibungskraft zwischen Sattel 6 und Isolierschicht 8 übersteigende Kräfte parallel zur Unterseite 7 des Sattels bzw. zur Oberseite 5 des Fundaments 4 übertragen. Fig. 5 schematically shows a section of the in Fig. 3 shown storage in an enlarged view. Unlike in the Fig. 2 and 4 shown storage is in the in the Fig. 3 and 5 shown storage no web 10 on the flat bottom 7 of the saddle 6 is arranged. The flat bottom 7 of the saddle 6 can therefore slide on the insulating layer 8. Between the saddle 6 and the foundation 4, no or at least no forces exceeding the frictional force between the saddle 6 and the insulating layer 8 are transmitted parallel to the underside 7 of the saddle or to the upper side 5 of the foundation 4.

Fig. 6 zeigt einen Teilquerschnitt durch die oben in den Fig. 2 und 3 gezeigte Konsole 14 und Abstützungen 15. Die dargestellte Schnittebene liegt senkrecht zur Längsachse des Schiffes. Die Abstützung 15 umschließt die Konsole 14 in Form eines umgekehrten "U". Anders ausgedrückt bilden Abstützung 15 und Fundament 4 zusammen einen Tunnel oder Kanal, in dem die Konsole 14 angeordnet ist. Zwischen der Oberseite 5 des Fundaments 4 und der Konsole 14 ist eine Isolierschicht 8 angeordnet, und zwischen der Konsole 14 und der Abstützung 15 ist eine Isolierschicht 16 angeordnet. Durch trogförmige Ausgestaltung des Fundaments 4 ist die Isolierschicht 8 gegen Verschiebung gegenüber dem Fundament 4 gesichert. An der Unterseite der Konsole 14 und senkrecht zu derselben ist ein Steg 12 parallel zur Schiffslängsachse angeordnet, der in eine entsprechende Ausnehmung in der Isolierschicht 8 greift. Durch Formschluss werden horizontale Kräfte quer zur Schiffslängsachse zwischen der Konsole 14 und dem Steg 12 einerseits und der Isolierschicht 8 und dem Fundament 4 andererseits übertragen und eine Verschiebung der Konsole 14 und damit auch des Tanks quer zur Schiffslängsachse verhindert. Die Abstützung 15 verhindert überdies ein Abheben der Konsole 14 und damit des mit ihr verbundenen Sattels 6 von der Isolierschicht 8 und dem Fundament 4. Fig. 6 shows a partial cross section through the top in the FIGS. 2 and 3 shown console 14 and supports 15. The illustrated section plane is perpendicular to the longitudinal axis of the vessel. The support 15 encloses the console 14 in the form of an inverted "U". In other words, support 15 and foundation 4 together form a tunnel or channel in which the console 14 is arranged. Between the top 5 of the foundation 4 and the console 14, an insulating layer 8 is arranged, and between the bracket 14 and the support 15, an insulating layer 16 is arranged. By trough-shaped design of the foundation 4, the insulating layer 8 is secured against displacement relative to the foundation 4. At the bottom of the console 14 and perpendicular to the same, a web 12 is arranged parallel to the ship's longitudinal axis, which engages in a corresponding recess in the insulating layer 8. By positive engagement horizontal forces are transmitted transversely to the ship's longitudinal axis between the bracket 14 and the web 12 on the one hand and the insulating layer 8 and the foundation 4 on the other hand and prevents displacement of the console 14 and thus the tank transversely to the ship's longitudinal axis. The support 15 also prevents lifting of the console 14 and thus the associated saddle 6 of the insulating layer 8 and the foundation. 4

Fig. 7 zeigt schematisch einen Schnitt nach der Linie A-A in Fig. 6. Es ist erkennbar, dass die Konsole 14 an den Sattel 6 bzw. dessen ebenen Unterseite 7 oder die die ebene Unterseite 7 des Sattels 6 bildende Platte angeformt oder mit dieser einstückig ausgeführt ist. Die Isolierschicht 16 ist rechteckig und durch eine trogförmige Ausgestaltung der Oberseite der Konsole 14 gegenüber dieser gegen Verrutschen gesichert. Seitlich verbleibt zwischen der Konsole 14 und der Abstützung 15 ein Spalt. Eine Führung in Richtung quer zur Schiffslängsachse erfolgt ausschließlich durch den in Fig. 6 gezeigten Steg 12 in Wechselwirkung mit der Ausnehmung 13 in der Isolierschicht 8. Fig. 7 schematically shows a section along the line AA in Fig. 6 , It can be seen that the console 14 is formed on the saddle 6 or its flat bottom 7 or the flat bottom 7 of the saddle 6 forming plate or designed in one piece with it. The insulating layer 16 is rectangular and secured by a trough-shaped configuration of the top of the console 14 against this against slipping. The side remains between the bracket 14 and the support 15, a gap. A guide in the direction transverse to the ship's longitudinal axis is made exclusively by the in Fig. 6 shown web 12 in interaction with the recess 13 in the insulating layer. 8

Fig. 8 ist eine schematische Darstellung der ebenen Unterseiten 7 der Sättel 6 eines in Fig. 8 nicht gezeigten Tanks. Die ebenen Unterseiten 7 der Sättel weisen ihre größte Ausdehnung in Richtung quer zur Schiffslängsachse 2 auf. Wie bereits in Fig. 1 erkennbar ist, weisen die ebenen Unterseiten 7 der Sättel 6 in dieser Richtung annähernd die Breite des Tanks auf. Angeformt an die die ebenen Unterseiten 7 der Sättel bildenden Platten sind die Konsolen 14 nahe der Schiffslängsachse 2 vor und hinter jedem Sattel angeordnet. An den Konsolen 14 sind jeweils auf der Schiffslängsachse 2 die auch in Fig. 6 gezeigten Stege 12 angeordnet. Bei der in Fahrtrichtung des Schiffes hinteren Lagerung 21 ist ferner der auch in den Fig. 2 und 4 gezeigte Steg 10 quer zur Schiffslängsachse 2 an der ebenen Unterseite 7 des Sattels angeordnet. Der Steg 10 nimmt Kräfte parallel zur Schiffslängsachse 2 auf und verhindert eine Verschiebung des Tanks gegenüber dem Schiffsrumpf in Richtung der Schiffslängsachse 2. Die Stege 12 nehmen Kräfte quer zur Schiffslängsachse auf und verhindern eine Verschiebung des Tanks gegenüber dem Schiffsrumpf quer zur Schiffslängsachse 2. Fig. 8 is a schematic representation of the flat bottom sides 7 of the saddles 6 of a Fig. 8 not shown tanks. The flat undersides 7 of the saddles have their greatest extent in the direction transverse to the ship's longitudinal axis 2. As already in Fig. 1 can be seen, the flat undersides 7 of the saddles 6 in this direction approximately the width of the tank. Shaped to the flat undersides 7 of the saddles forming plates, the brackets 14 are arranged near the ship's longitudinal axis 2 in front of and behind each saddle. At the consoles 14 are each on the ship's longitudinal axis 2 in Fig. 6 shown webs 12 arranged. When the rear in the direction of travel of the ship 21 is also in the Fig. 2 and 4 shown web 10 is arranged transversely to the ship's longitudinal axis 2 on the flat bottom 7 of the saddle. The web 10 receives forces parallel to the ship's longitudinal axis 2 and prevents displacement of the tank relative to the ship's hull in the direction of the ship's longitudinal axis 2. The webs 12 absorb forces transverse to the ship's longitudinal axis and prevent displacement of the tank relative to the ship's hull transverse to the ship's longitudinal axis. 2

Alternativ ist der Steg 10 nicht an der in Fahrtrichtung des Schiffes hinteren Lagerung 21, sondern an der in Fahrtrichtung des Schiffes vorderen Lagerung 22 angeordnet. Abweichend von den Darstellungen in den Figuren können ferner die ebenen Unterseiten 7 der Sättel 6 mehrteilig sein und/oder von der Rechteckform abweichen. Ferner können die Stege 12 in separaten Abschnitten der Sättel 6 und/oder in anderer Anzahl vorgesehen sein.Alternatively, the web 10 is not arranged on the rear in the direction of travel of the ship 21 storage, but on the front in the direction of travel of the ship 22 storage. Notwithstanding the illustrations in the figures, furthermore, the flat undersides 7 of the saddles 6 can be multi-part and / or deviate from the rectangular shape. Furthermore, the webs 12 may be provided in separate sections of the saddles 6 and / or in other numbers.
