- FIG. 3 is the Fig. 1 corresponding situation with waves, wind and flow shown from the same direction, now a tanker 20 is moored to the loading platform 2.
- the loading platform 2 system and tanker 20 moored thereto have an asymmetry that results in torque being applied to the deck 2 and tanker 20 system, the torque being the longitudinal side of the docking platform 2 facing away from the tanker the incoming waves, wind and the ocean current turns.
- the state of lowest total resistance of loading platform 2 with the tanker 20 moored to it is thus achieved in a position in which the tanker 20 lies on that longitudinal side of the loading platform 2, which is slightly opposite to incoming swell, wind and current.
- Fig. 4 a corresponding situation is presented in which waves, wind and ocean currents come from different directions.

Description
Die vorliegende Erfindung betrifft eine schwimmfähige LNG - und/oder LPG-Verladeplattform zum Sammeln, Prozessieren und Speichern von zugeführtem Erdgas und zur Verladung von verflüssigtem Erdgas in Form von LNG (Liquefied Natural Gas) und/oder LPG (Liquefied Petrol Gas) auf Tankschiffe, mit: einem länglichen Rumpf mit Verankerungseinrichtungen an dessen einem Ende, die so ausgestaltet sind, dass der Rumpf frei drehbar relativ zu einem Verankerungspunkt am Meeresgrund verankerbar ist, Vertäuungseinrichtungen zum Vertäuen eines Tankschiffs Seite an Seite an dem Rumpf, einem Flüssiggastransfersystem mit einer Mehrzahl von Leitungen, die in Leitungskupplungen münden, die zum Anschluss an standardmäßige Lade/Entlade-Stutzen an Tankschiffen ausgelegt sind.The present invention relates to a buoyant LNG and / or LPG loading platform for collecting, processing and storing supplied natural gas and for loading liquefied natural gas in the form of liquified natural gas (LNG) and / or LPG (liquefied petroleum gas) on tankers, comprising: an elongated hull having anchoring means at one end thereof adapted to anchor the hull freely rotatable relative to an anchoring point at the seabed, mooring means for mooring a tanker side by side on the hull, a liquefied gas transfer system having a plurality of conduits leading to line couplings designed for connection to standard loading / unloading nozzles on tankers.
Eine derartige Verladeplattform wurde von Shell unter dem Projektnamen "Prelude FLNG" (Floating Liquefied Natural Gas Facility) vorgestellt. Die Prelude-Plattform hat einen länglichen Rumpf, der eine Länge von 488 m und eine Breite von 74 m hat. Es sind Verankerungseinrichtungen an einem Ende des Rumpfes vorgesehen, die so ausgestaltet sind, dass der Rumpf frei drehbar relativ zu einem Verankerungspunkt am Meeresgrund verankerbar ist; solche Verankerungseinrichtungen werden auch als "Turret Mooring Systems" bezeichnet. Die Verladeplattform ist ferner mit Leitungen versehen, die zu verschiedenen in der Umgebung am Meeresgrund befindlichen Förderanlagen für Erdgas führen. Das zugeleitete Erdgas wird auf der Verladeplattform verfahrenstechnisch prozessiert und anschließend in verflüssigtem Zustand in Form von LNG und/oder LPG lieferfertig in Speichern auf der Verladeplattform gelagert. Das so prozessierte LNG und/oder LPG wird auf Tankschiffe für Flüssiggas verladen und zu den Verbrauchsorten transportiert. Zum Andocken der Tankschiffe Seite an Seite sind am Rumpf der Verladeplattform Vertäuungseinrichtungen vorgesehen. Ferner ist auf der Verladeplattform ein Flüssiggastransfersystem mit einer Mehrzahl von voneinander unabhängig gehandhabten Leitungen vorgesehen, die jeweils in eine mit der Leitung verbundene Leitungskupplung münden. Diese Leitungskupplungen sind zum Anschluss an standardmäßige Lade/Entlade-Stutzen an Tankschiffen ausgelegt. Das Flüssiggastransfersystem besitzt jeweils einzeln zu handhabende Hebevorrichtungen, mit denen die Leitungsenden so positioniert werden können, dass die Leitungskupplungen des Flüssiggastransfersystems unmittelbar vor den standardmäßigen Lade/Entlade-Stutzen an dem Tankschiff liegen und jeweils einzeln miteinander gekoppelt werden können, um LNG und/oder LPG aus den Speichern der Verladeplattform in ein angedocktes Tankschiff fördern zu können. Die Leitungen des Flüssiggastransfersystems werden durch feste Rohre gebildet, die über Drehgelenke miteinander verbunden sind und sich damit beweglich an die Position der Lade/Entlade-Stutzen anpassen bzw. ihnen folgen können. Das Flüssiggastransfersystem ist in Längsrichtung der Verladeplattform an einem festgelegten Ort fest montiert. Das Tankschiff muss daher so an der Verladeplattform festgemacht werden, dass die in Längsrichtung des Tankschiffes ebenfalls an einem festen Ort liegenden Lade/Entlade-Stutzen und die Leitungskupplungen in engen Grenzen in Ausrichtung zueinander sind, so dass die Leitungskupplungen des Flüssiggastransfersystems mit den Lade/Entlade-Stutzen des Tankschiffs gekoppelt werden können.Such a loading platform was introduced by Shell under the project name "Prelude FLNG" (Floating Liquefied Natural Gas Facility). The Prelude platform has an elongated hull that is 488 meters long and 74 meters wide. There are anchoring means provided at one end of the hull, which are designed so that the hull is freely rotatable relative to an anchoring point anchored to the seabed; such anchoring devices are also referred to as "turret mooring systems". The loading platform is further provided with lines leading to various natural gas production facilities located at the bottom of the sea. The natural gas fed in is process-technically processed on the loading platform and then stored in the liquefied state in the form of LNG and / or LPG ready to be stored in stores on the loading platform. The LNG and / or LPG processed in this way is loaded onto tankers for LPG and transported to the consumption locations. To dock the tankers side by side mooring facilities are provided on the hull of the loading platform. Further, on the Verladeplattform a Flüssiggastransfersystem provided with a plurality of independently handled lines, each of which opens into a line coupling connected to the line. These line couplings are designed for connection to standard charging / discharging ports on tankers. The liquefied natural gas transfer system has individually operable jacks that can be used to position the conduit ends such that the liquid gas transfer system conduit couplings are immediately prior to the standard charge / discharge port on the tanker and individually coupled to one another to supply LNG and / or LPG to be able to extract from the storages of the loading platform into a docked tanker. The lines of the Flüssiggastransfersystems are formed by solid tubes, which are interconnected via hinges and thus can be adapted to move to the position of the charge / discharge nozzle or follow them. The liquid gas transfer system is fixedly mounted in the longitudinal direction of the loading platform at a fixed location. The tanker must therefore be moored to the loading platform such that the loading / unloading spigots also located at a fixed location in the longitudinal direction of the tanker and the line couplings are in close alignment with each other, so that the line couplings of the LPG transport system with the loading / unloading Socket of the tanker can be coupled.
Der Drehbarkeit der Verankerung der Verladeplattform am Meeresboden liegt folgende Überlegung zugrunde. Eine solche Verankerung erlaubt es, dass sich die Verladeplattform ohne aktives Zutun zu den anlaufenden Wellen, zum Wind und zur Meeresströmung derart ausrichtet, dass sie den geringsten Widerstand bietet. Dies ist schematisch in
In
Tatsächlich ist diese Verdrehung der Verladeplattform 2 auch erwünscht, denn es ergibt sich dadurch der Effekt, dass das Tankschiff 20 in gewissem Umfang im "Wellenschatten" der Verladeplattform 2 liegt, d.h. die dem Tankschiff 20 zugewandte Seite der Verladeplattform 2 ist leicht von der Richtung des Wellengangs abgewandt. Unter typischen Bedingungen von Wellengang, Wind und Strömung neigt sich die Verladeplattform 2 um bis zu 30° zu dem eingehenden Wellengang. Dadurch wird ein geschützter Bereich im "Wellenschatten" der Verladeplattform geschaffen, in dem das Tankschiff liegt. Durch die Lage im Wellenschatten werden Relativbewegungen zwischen Verladeplattform 2 und daran verankertem Tankschiff 20 verringert. Dies ist von großer Bedeutung, um die Belastung auf die Vertäuung und die Bewegung und Belastung auf das angekoppelte Flüssiggastransfersystem in tolerierbaren Grenzen zu halten.In fact, this twisting of the
Es ist Aufgabe der vorliegenden Erfindung, eine Verladeplattform der oben beschriebenen Art so zu verbessern, dass sie an den Typ des zu vertäuenden und zu befüllenden Tankschiffs anpassbar ist, so dass die Relativbewegungen zwischen Tankschiff und Verladeplattform aufgrund von Wellen, Wind und Strömung abhängig vom Tankschifftyp möglichst gering sein können. Insbesondere soll die Vertäuung und Befüllung des Tankschiffs an der Verladeplattform in einer solchen Weise möglich sein, dass das Tankschiff abhängig vom Typ des Tankschiffes in möglichst großem Maße im Wellenschatten der Verladeplattform liegt, um so eine Konstellation von Verladeplattform und daran vertäutem Tankschiff zu schaffen, in der die Relativbewegungen zwischen Verladeplattform und Tankschiff verringert sind.It is an object of the present invention to improve a loading platform of the type described above so that it is adaptable to the type of tanker to be moored and filled, so that the relative movements between tanker and loading platform due to waves, wind and flow depending on the tanker type can be as low as possible. In particular, the mooring and filling of the tanker at the loading platform should be possible in such a way that the tanker depends on the type of tanker in the maximum extent in the wave shadow of the loading platform, so as to create a constellation of loading platform and moored tanker, in the relative movements between loading platform and tanker are reduced.
Zur Lösung dieser Aufgabe dienen die kennzeichnenden Merkmale des Anspruchs 1. Vorteilhafte Ausführungsformen der erfindungsgemäßen Verladeplattform sind in den Unteransprüchen aufgeführt.To achieve this object, the characterizing features of
Erfindungsgemäß ist vorgesehen, dass das Flüssiggastransfersystem in Längsrichtung des Rumpfes verfahrbar auf der Verladeplattform gelagert ist, so dass die Positionierung der Leitungskupplungen des Flüssiggastransfersystems und damit die der Leitungskupplungen an eine gewünschte Vertäuungsposition eines Tankschiffs in Längsrichtung des Rumpfs der Verladeplattform anpassbar ist. Mit der gewünschten Vertäuungsposition des Tankschiffs ergibt sich auch die Lage der Lade/Entlade-Stutzen in Längsrichtung des Rumpfes der Verladeplattform, auf die die Lage des Flüssiggastransfersystems einstellbar ist, so dass sich Lade/Entlade-Stutzen und Leitungskupplungen gegenüberliegen, wenn sich das betroffene Tankschiff in der optimalen Längsposition an der Verladeplattform befindet.According to the invention, it is provided that the liquefied gas transfer system is mounted movably on the loading platform in the longitudinal direction of the fuselage so that the positioning of the line couplings of the liquefied gas transfer system and thus of the line couplings can be adapted to a desired mooring position of a tanker in the longitudinal direction of the hull of the loading platform. With the desired mooring position of the tanker also results in the location of the loading / unloading nozzle in the longitudinal direction of the hull of the loading platform to which the position of the Flüssiggastransfersystems is adjustable so that charge / discharge nozzle and line couplings face each other when the affected tanker is in the optimal longitudinal position on the loading platform.
Im Zusammenhang mit der vorliegenden Erfindung hat sich herausgestellt, dass die durch die Schrägstellung der Verladeplattform gegenüber der Richtung des eingehenden Wellengangs und die dadurch bewirkte Abschirmung des an der Verladeplattform vertäuten Tankschiffs sich abhängig vom Typ des Tankschiffs, zum Beispiel abhängig von dessen Länge, Breite, Tiefgang etc., in der Weise optimieren lässt, dass Relativbewegungen zwischen Tankschiff und Verladeplattform möglichst gering sind, indem das Tankschiff in einer danach gut geeigneten Längsposition in Längsrichtung der Verladeplattform daran vertäut wird. Da die Lage der Lade/Entlade-Stutzen an den Tankschiffen in deren Längsrichtung für ein gegebenes Tankschiff fest vorgegeben und nicht variabel ist, ist erfindungsgemäß vorgesehen, dass das Flüssiggastransfersystem in Längsrichtung des Rumpfes der Verladeplattform verfahrbar darauf gelagert ist, so dass jedes Tankschiff eines gegebenen Typs in gewünschter Lage in Längsrichtung an der Verladeplattform daran vertäut werden kann, um Relativbewegungen zwischen Tankschiff und Verladeplattform möglichst gering zu halten, und das Flüssiggastransfersystem auf die sich daraus ergebende Stellung der Lade/Entlade-Stutzen an dem Tankschiff eingestellt werden kann.In the context of the present invention, it has been found that the tank vessel moored by the inclination of the docking platform with respect to the direction of the incoming swell and the shielding of the tanker moored thereby depends on the type of tanker, for example, depending on its length, width, Draft etc., can be optimized in such a way that relative movements between the tanker and loading platform are as small as possible by the tanker is moored in a then well suited longitudinal position in the longitudinal direction of the loading platform. Since the location of the loading / unloading nozzles on the tankers in the longitudinal direction for a given tanker is fixed and not variable, the invention provides that the Flüssiggastransfersystem is mounted in the longitudinal direction of the hull of the loading platform movable thereon, so that each tanker of a given Type in the desired position in the longitudinal direction of the loading platform can be moored thereto to minimize relative movements between tanker and loading platform, and the Flüssiggastransfersystem can be adjusted to the resulting position of the loading / unloading nozzles on the tanker.
In einer vorteilhaften Ausführungsform weist das Flüssiggastransfersystem eine verfahrbar auf der Verladeplattform gelagerte Basis auf, an der eine Trägerstruktur montiert ist. Die Trägerstruktur hält einen quer verlaufenden Querträgerrahmen, an dem die Mehrzahl von Leitungen mit den Leitungskupplungen reihenförmig nebeneinander angeordnet aufgehängt sind.In an advantageous embodiment, the LPG transport system has a base movably mounted on the loading platform, on which a support structure is mounted. The support structure holds a transverse transverse support frame on which the plurality of ducts with the line couplings are suspended in rows arranged side by side.
In einer vorteilhaften Ausführungsform weisen die Leitungen des Flüssiggastransfersystems flexible Leitungen in Form von flexiblen Wellrohren oder Schläuchen für tiefgekühlte Flüssigkeiten auf. Durch die Flexibilität der Leitungen kann sich das Flüssiggastransfersystem an die sich im Seegang ständig ändernde Lage der Lade/Entlade-Stutzen eines Tankschiffs anpassen. In einer insoweit weiter bevorzugten Ausführungsform weist die Trägerstruktur des Flüssiggastransfersystems eine Hebeeinrichtung auf einer verfahrbar auf der Verladeplattform gelagerten Basis auf. Der Querträgerrahmen wird von der Hebeeinrichtung gehalten, so dass die vertikale Stellung des Querträgerrahmens und damit die der Leitungskupplungen relativ zur Verladeplattform eingestellt werden kann.In an advantageous embodiment, the lines of the liquefied natural gas transfer system have flexible lines in the form of flexible corrugated tubes or hoses for frozen liquids. Due to the flexibility of the pipes, the liquid gas transfer system can adapt to the constantly changing sea state of the loading / unloading ports of a tanker. In a further preferred embodiment, the support structure of the liquefied gas transfer system has a lifting device on a base movably mounted on the loading platform. The cross member frame is held by the lifting device, so that the vertical position of the cross member frame and thus the line couplings can be adjusted relative to the loading platform.
In einer bevorzugten Ausführungsform ist der Querträgerrahmen des Flüssiggastransfersystems in seiner Querausdehnung verstellbar ausgestaltet. Dadurch kann in der von dem Querträgerrahmen gehaltenen reihenförmigen Anordnung von Leitungskupplungen deren Abstand voneinander individuell eingestellt werden. Auf diese Weise können die Leitungskupplungen des Flüssiggastransfersystems in ihren Abständen an die der Lade/Entlade-Stutzen des Tankschiffs angepasst werden. Dazu kann in einer bevorzugten Ausführungsform der Querträgerrahmen eine Mehrzahl von gegeneinander verschiebbar gelagerten Querträgerrahmenelementen aufweisen, wobei die Leitungskupplungen mit unterschiedlichen Querträgerrahmenelementen verbunden sind, so dass durch Auseinanderstellen oder Zusammenziehen der Querträgerrahmenelemente die Abstände der Leitungskupplungen einstellbar sind.In a preferred embodiment, the crossbeam frame of the liquefied gas transfer system is designed to be adjustable in its transverse extent. As a result, in the row-shaped arrangement of line couplings held by the cross-member frame, their spacing from one another can be set individually. In this way, the line couplings of the Flüssiggastransfersystems can be adjusted in their distances to the loading / unloading nozzles of the tanker. For this purpose, in a preferred embodiment, the cross member frame having a plurality of mutually displaceably mounted cross member frame elements, wherein the line couplings are connected to different cross member frame elements, so that by spacing or contraction of the cross member frame elements, the distances of the line couplings are adjustable.
