Abstract

1. Устройство для подачи топлива в энергетическую установку судна для перевозки сжиженного газа, по меньшей мере, из одного резервуара (2) для сжиженного газа упомянутого судна, включающее насос (20), расположенный на дне резервуара, и емкость (23), расположенную в резервуаре вокруг насоса и рассчитанную на поддержание приема насоса в погруженном состоянии, отличающееся тем, что оно имеет расположенный в резервуаре жидкостный эжектор (12), позволяющий всасывать сжиженный газ на дне резервуара, и жидкостную линию (21, 22, 24, 250), соединяющую выходное отверстие насоса с входным отверстием инжектора, с одной стороны, и выходное отверстие инжектора с емкостью, с другой стороны. ! 2. Устройство для подачи по п.1, в котором емкость расположена на удалении от эжектора. ! 3. Устройство для подачи по п.1, в котором эжектор соприкасается с емкостью или расположен в емкости. ! 4. Устройство для подачи по одному из предшествующих пунктов, в котором емкость имеет профиль, способствующий наполнению за счет жидкости, поступающей из полного резервуара или за счет волны сжиженного газа. ! 5. Устройство для подачи по одному из пп.1-4, в котором упомянутая емкость имеет объем менее 1 м3. ! 6. Устройство для подачи по одному из пп.1-5, в котором упомянутый эжектор имеет всасывающий патрубок (14), входное отверстие которого расположено на меньшей высоте, чем прием насоса. ! 7. Устройство для подачи по одному из пп.1-6, включающее подающий трубопровод (28), соединяющий жидкостную линию с энергетической установкой. ! 8. Устройство для подачи по п.7, в котором подающий трубопровод (28) соединен с жидкостной линией между выходным отверстием инжектора и емкостью. ! 9. Устро 1. A device for supplying fuel to a ship’s power plant for transporting liquefied gas from at least one liquefied gas tank (2) of said vessel, comprising a pump (20) located at the bottom of the tank and a container (23) located in reservoir around the pump and designed to maintain the intake of the pump in a submerged state, characterized in that it has a liquid ejector (12) located in the reservoir, allowing suction of liquefied gas at the bottom of the reservoir, and a fluid line (21, 22, 24, 250) connecting day off about the bore of the pump with the inlet of the injector, on the one hand, and the outlet of the injector with a container, on the other hand. ! 2. The feed device according to claim 1, in which the container is located at a distance from the ejector. ! 3. The feeding device according to claim 1, wherein the ejector is in contact with the container or located in the container. ! 4. A device for supplying according to one of the preceding paragraphs, in which the container has a profile that facilitates filling due to liquid coming from a full tank or due to a wave of liquefied gas. ! 5. A feeding device according to one of claims 1 to 4, wherein said container has a volume of less than 1 m3. ! 6. A feed device according to one of claims 1 to 5, in which said ejector has a suction pipe (14), the inlet of which is located at a lower height than the pump intake. ! 7. A device for supplying according to one of claims 1 to 6, including a supply pipe (28) connecting the liquid line to the power plant. ! 8. The supply device according to claim 7, in which the supply pipe (28) is connected to the liquid line between the outlet of the injector and the container. ! 9. Arranging

Claims

1. A device for supplying fuel to a ship’s power plant for transporting liquefied gas from at least one liquefied gas tank (2) of said vessel, comprising a pump (20) located at the bottom of the tank and a container (23) located in reservoir around the pump and designed to maintain the intake of the pump in a submerged state, characterized in that it has a liquid ejector (12) located in the reservoir, allowing suction of liquefied gas at the bottom of the reservoir, and a fluid line (21, 22, 24, 250) connecting day off about the bore of the pump with the inlet of the injector, on the one hand, and the outlet of the injector with a container, on the other hand.

2. The feed device according to claim 1, in which the container is located at a distance from the ejector.

3. The feeding device according to claim 1, wherein the ejector is in contact with the container or located in the container.

4. A device for supplying according to one of the preceding paragraphs, in which the container has a profile that facilitates filling due to liquid coming from a full tank or due to a wave of liquefied gas.

5. A device for feeding according to one of claims 1 to ⁴ , in which said container has a volume of less than 1 m ³ .

6. A feed device according to one of claims 1 to 5, in which said ejector has a suction pipe (14), the inlet of which is located at a lower height than the pump intake.

7. A device for supplying according to one of claims 1 to 6, including a supply pipe (28) connecting the liquid line to the power plant.

8. The supply device according to claim 7, in which the supply pipe (28) is connected to the liquid line between the outlet of the injector and the container.

9. A device for supplying according to one of claims 1 to 8, including an exhaust pump (54) or any other pump of the vessel, by means of a pipeline (55) connected to said liquid line upstream of the ejector.

10.
