Abstract

The liquefied gas (2), in cargo tank(2) (1) at about atmospheric pressure, supplies (4) naturally evaporating gas (3) to a compressor (5). Further supplies are obtained by pumping (8) liquefied gas through an evaporator (9). The gas passes to the prime mover (7), a diesel engine or gas turbine driving the screw (10) through a clutch (11). For high-speed diesel, or turbine, drive, a reduction gear (12) is included. Opt., quadruple diesel-electric drives are installed. For environmental reasons, gas cannot be vented, and burning must continue when the ship is stationary. Pumping (8) stops, and the prime mover, disconnected (11) from the screw, is connected by another clutch (13) to a Froude hydraulic brake (14). Opt., this is permanently connected, but normally run dry.

Description

Installation de propulsion sur un navire de transport de aaz liquéfié.Propulsion installation on a liquefied az transport vessel.

La présente invention concerne une installation de propulsion sur un navire de transport de gaz liquéfié. The present invention relates to a propulsion installation on a liquefied gas transport ship.

L'invention s'applique en particulier aux navires méthaniers. The invention applies in particular to LNG carriers.

Actuellement la propulsion des navires méthaniers est effectuée par le moyen d'une turbine à vapeur. LNG ships are currently propelled by a steam turbine.

Le combustible de la chaudière alimentant la turbine en vapeur est au moins en partie constitué par du gaz provenant de l'évaporation naturelle du méthane transporté. The fuel of the boiler supplying the steam turbine is at least partly constituted by gas coming from the natural evaporation of the transported methane.

En effet, celui-ci est transporté liquide, à pression ambiante, dans des cuves isolées. I1 en résulte une évaporation naturelle significative. Le gaz provenant de cette évaporation naturelle est donc utilisé comme combustible pour la propulsion.Indeed, it is transported liquid, at ambient pressure, in insulated tanks. This results in significant natural evaporation. The gas from this natural evaporation is therefore used as fuel for propulsion.

Lorsque le navire est stoppé, il est donc nécessaire de dissiper l'énergie produite par la combustion du gaz d'évaporation des cuves car il est interdit de rejeter directement à l'atmosphère le gaz provenant des cuves et on ne peut pas non plus laisser monter la pression au-dessus d'un certain seuil. On continue donc à alimenter la chaudière par les gaz d'évaporation des cuves et la vapeur produite, au lieu d'être détendue dans la turbine, est directement envoyée au condenseur en court-circuitant la turbine. When the ship is stopped, it is therefore necessary to dissipate the energy produced by the combustion of the evaporation gas from the tanks because it is forbidden to discharge directly to the atmosphere the gas coming from the tanks and one cannot either leave increase the pressure above a certain threshold. We therefore continue to supply the boiler with the evaporation gases from the tanks and the steam produced, instead of being expanded in the turbine, is directly sent to the condenser by short-circuiting the turbine.

La présente invention a pour but de proposer un système de propulsion plus économique ne faisant pas appel à la vapeur comme moyen intermédiaire moteur et ne comportant donc pas de condenseur, mais incluant un moyen adapté au système pour résoudre le problème posé par l'évaporation naturelle du gaz liquéfié et sa consommation lorsque le navire est à l'arrêt. The object of the present invention is to propose a more economical propulsion system which does not use steam as an intermediate motor means and therefore does not include a condenser, but which includes means adapted to the system for solving the problem posed by natural evaporation. liquefied gas and its consumption when the ship is stationary.

L'invention a ainsi pour objet une installation de propulsion pour un navire de transport de gaz liquéfié comportant au-moins une cuve de gaz liquéfié, caractérisée en ce qu'elle comprend au moins un moteur alimenté au-moins en partie par les gaz provenant de l'évaporation naturelle dudit gaz liquéfié dans ladite cuve, ledit moteur entraînant directement, ou par l'intermédiaire d'une chaîne de transformation de l'énergie, au-moins une hélice de propulsion, un accouplement embrayable permettant en outre d'accoupler ou de désaccoupler l'hélice de la partie motrice et en ce qu'elle comporte en outre un organe de dégradation de l'énergie mécanique en énergie calorifique, ledit organe étant relié à une sortie mécanique de l'installation. The subject of the invention is therefore a propulsion installation for a liquefied gas transport vessel comprising at least one tank of liquefied gas, characterized in that it comprises at least one engine supplied at least in part by the gases originating natural evaporation of said liquefied gas in said tank, said motor driving directly, or via an energy transformation chain, at least one propeller, a clutch coupling allowing in addition to couple or uncoupling the propeller from the driving part and in that it further comprises a member for degrading mechanical energy into heat energy, said member being connected to a mechanical outlet of the installation.

Avantageusement ledit organe de dégradation de l'énergie mécanique est un frein hydraulique. Advantageously, said mechanical energy degradation member is a hydraulic brake.

Selon une réalisation particulière, ledit moteur est un moteur diésel qui entraîne ladite hélice par l'intermédiaire d'un chaîne de transmission comprenant un générateur électrique entraîné par ledit moteur diésel, le générateur alimentant un moteur électrique entraînant l'hélice par l'intermédiaire d'un réducteur et d'un embrayage. According to a particular embodiment, said engine is a diesel engine which drives said propeller via a transmission chain comprising an electric generator driven by said diesel engine, the generator supplying an electric motor driving the propeller via 'a reducer and a clutch.

Dans cette configuration, l'organe de dégradation de l'énergie mécanique, qui est avantageusement un frein hydraulique est avantageusement entraîné par le moteur électrique par l'intermédiaire d'un embrayage. In this configuration, the mechanical energy degradation member, which is advantageously a hydraulic brake, is advantageously driven by the electric motor via a clutch.

Selon d'autres réalisations, ledit moteur est un moteur diésel entraînant directement ou par l'intermédiaire d'un réducteur, et à travers un embrayage, l'hélice de propulsion. I1 peut s'agir également d'une turbine à gaz. According to other embodiments, said engine is a diesel engine driving directly or via a reduction gear, and through a clutch, the propeller. It can also be a gas turbine.

L'invention va maintenant être décrite en se référant au dessin annexé dans lequel
La figure 1 est une vue schématique illustrant le principe de l'invention.The invention will now be described with reference to the accompanying drawing in which
Figure 1 is a schematic view illustrating the principle of the invention.

La figure 2 est une vue illustrant un mode de réalisation préféré de l'invention. Figure 2 is a view illustrating a preferred embodiment of the invention.

La figure 1 montre ainsi schématiquement une installation de propulsion d'un navire de transport de gaz liquéfié. I1 s'agit par exemple d'un méthanier.  Figure 1 thus schematically shows a propulsion installation of a liquefied gas transport ship. It is, for example, an LNG carrier.

En 1 on a figuré une cuve du navire contenant le méthane liquide 2. La cuve 1 est isolée et le méthane liquide 2 est transporté pratiquement à la pression atmosphérique ambiante. I1 en résulte une évaporation naturelle importante utilisée pour la propulsion du navire. In 1 there is shown a vessel of the vessel containing the liquid methane 2. The vessel 1 is insulated and the liquid methane 2 is transported practically at ambient atmospheric pressure. This results in significant natural evaporation used for the propulsion of the ship.

Le gaz d'évaporation naturelle 3 est envoyée par une conduite 4 vers un compresseur 5 entraîné par un moteur d'entraînement 6.The natural evaporation gas 3 is sent via a line 4 to a compressor 5 driven by a drive motor 6.

A la sortie du compresseur 5, le gaz est envoyé vers un moteur de propulsion 7. At the outlet of the compressor 5, the gas is sent to a propulsion engine 7.

L'appoint nécessaire de combustible est fourni soit par du méthane liquide pompé dans la cuve 7 par une pompe 8, envoyé vers un évaporateur 9 puis vers le compresseur 5, soit par du combustible liquide tel que du fuel oil ou du diesel oil. The necessary fuel supply is provided either by liquid methane pumped into the tank 7 by a pump 8, sent to an evaporator 9 then to the compressor 5, or by liquid fuel such as fuel oil or diesel oil.

Le moteur 7 est par exemple un moteur diésel qui entraîne une hélice 10 par l'intermédiaire d'un embrayage 11, directement s'il s'agit d'un moteur diésel lent ou à travers un réducteur 12 dans le cas contraire. The engine 7 is for example a diesel engine which drives a propeller 10 via a clutch 11, directly if it is a slow diesel engine or through a reduction gear 12 otherwise.

Le moteur 7 peut également être une turbine à gaz qui entraîne alors l'hélice 10 par l'intermédiaire d'un réducteur 12 et de l'embrayage 11. The engine 7 can also be a gas turbine which then drives the propeller 10 via a reduction gear 12 and the clutch 11.

Le moteur 7, diésel ou turbine est en outre relié, par un embrayage 13 à un organe 14 de dégradation de l'énergie mécanique en énergie calorifique. I1 s'agit d'un dispositif mécanique quelconque mettant en action un agitateur rotatif ou non se déplaçant dans un fluide visqueux : liquide, gazeux ou un mélange des deux. I1 s'agit par exemple d'un frein hydraulique tel qu'un frein de Froude. The engine 7, diesel or turbine is further connected, by a clutch 13 to a member 14 for degrading mechanical energy into heat energy. I1 is any mechanical device activating a rotary agitator or not moving in a viscous fluid: liquid, gaseous or a mixture of both. I1 is for example a hydraulic brake such as a Froude brake.

Cet organe 14, au lieu d'être relié directement à l'arbre du moteur 7 peut également, dans le cas où on utilise un réducteur 12, être relié à une sortie intermédiaire du réducteur. This member 14, instead of being connected directly to the motor shaft 7 can also, in the case where a reduction gear 12 is used, be connected to an intermediate output of the reduction gear.

Ainsi, en cas d'arrêt du navire, l'installation permet facilement grâce à l'utilisation de l'organe 14 de dissiper en calories l'énergie mécanique du moteur 7 produite par la combustion du gaz provenant de l'évaporation naturelle du méthane 2 dans la cuve 1. Dans cette occurrence, on arrête la pompe 8, on débraye l'embrayage 11 et on embraye l'embrayage 13. Thus, in the event of the vessel stopping, the installation makes it easy, thanks to the use of the member 14, to dissipate in calories the mechanical energy of the engine 7 produced by the combustion of the gas originating from the natural evaporation of methane 2 in the tank 1. In this occurrence, the pump 8 is stopped, the clutch 11 is disengaged and the clutch 13 is engaged.

L'organe 14 peut fonctionner soit à des vitesses différentes en fonction de l'énergie à dégrader, soit en remplissant l'organe 14 d'une quantité appropriée de fluide. The member 14 can operate either at different speeds depending on the energy to be degraded, or by filling the member 14 with an appropriate quantity of fluid.

L'organe 14 peut, comme on l'a représenté sur la figure, être entraîné par l'intermédiaire d'un embrayage 13 mais il peut aussi être relié directement sans embrayage à une sortie mécanique de l'installation et donc être entraîné en permanence. Dans ce dernier cas, il est entraîné à vide sans fluide. The member 14 can, as shown in the figure, be driven by means of a clutch 13 but it can also be connected directly without a clutch to a mechanical outlet of the installation and therefore be permanently driven . In the latter case, it is vacuum driven without fluid.

En se référant maintenant à la figure 2, on va décrire une application particulière, non limitative relative à une propulsion diésel-électrique. Referring now to Figure 2, we will describe a particular, non-limiting application relating to diesel-electric propulsion.

Dans cette figure, le gaz, à la sortie du compresseur 5 alimente quatre moteurs diésels 15 qui entraînent chacun un alternateur 16. Ceux-ci alimentent en parallèle deux convertisseurs de fréquence 17 alimentant chacun un moteur électrique 18. In this figure, the gas, at the outlet of the compressor 5 feeds four diesel engines 15 which each drive an alternator 16. These feed in parallel two frequency converters 17 each feeding an electric motor 18.

Les moteurs 18 attaquent un réducteur 19 par l'intermédiaire de deux embrayages 20. The motors 18 drive a reduction gear 19 by means of two clutches 20.

Le réducteur 19 entraîne l'hélice 10. The reduction gear 19 drives the propeller 10.

Chaque moteur électrique 18 entraîne un frein hydraulique 21 du type FROUDE par l'intermédiaire d'un embrayage 22. Each electric motor 18 drives a hydraulic brake 21 of the FROUDE type by means of a clutch 22.

Un circuit d'eau de mer 23 permet d'évacuer les calories. A seawater circuit 23 allows the calories to be removed.

Ici, les freins hydrauliques 21 sont embrayés sur les moteurs électriques 18. Here, the hydraulic brakes 21 are engaged on the electric motors 18.

On pourrait bien entendu les embrayer sur le réducteur 19 ou sur l'un de ses pignons ou sur la ligne d'arbre du navire.  One could of course engage them on the reduction gear 19 or on one of its pinions or on the shaft line of the ship.
