Title:
LIQUEFIED GAS FUEL SUPPLY MECHANISM FOR VESSEL
Document Type and Number:
Japanese Patent JP2017078448
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a liquefied gas fuel supply mechanism for a vessel capable of curving wasteful consumption of liquefied gas fuel while controlling fluctuation of inner pressure due to boil-off gas in a storage container.SOLUTION: A liquefied gas fuel supply mechanism for a vessel comprises: a storage container 1 which stores liquefied gas fuel; a boil-off gas derivation pipe 2 which derives boil-off gas of the liquefied gas fuel from the storage container 1; a liquefied gas fuel derivation pipe 4 which derives the liquefied gas fuel from the storage container 1; and a confluence 7 where the boil-off gas derivation pipe 2 joins the liquefied gas fuel derivation pipe 4. The confluence 7 is adapted to make the boil-off gas derived through the boil-off gas derivation pipe 2 join the liquefied gas fuel derived through the liquefied gas fuel derivation pipe 4 at a position not lower than a liquid level of the liquefied gas fuel stored in the storage container 1. The liquefied gas fuel supply mechanism allows the liquefied gas fuel to be applied to a small vessel such as a tag boat without requiring the same to have a re-liquefaction mechanism.SELECTED DRAWING: Figure 1
