Offshore floating facility

Abstract

An offshore floating facility (10) comprises a boat hull (12) and an intermediate medium carburetor (16). The intermediate medium carburetor (16) has a pump (34) that draws in seawater, an intermediate medium evaporator (E1) in which an intermediate medium is evaporated by the seawater drawn in by the pump (34), an LNG evaporator (E2) in which LNG is gasified by the intermediate medium evaporatedin the intermediate medium evaporator (E1), a gas pipeline (21) that guides the intermediate medium evaporated in the intermediate medium evaporator (E1) to the LNG evaporator (E2), and a liquid pipeline (22) that guides the intermediate medium condensed in the LNG evaporator (E2) to the intermediate medium evaporator (E1). The LNG evaporator (E2) is disposed on a deck (12a) of the boat hull (12),the intermediate medium evaporator (E1) is disposed below the deck (12a), and the intermediate medium naturally circulates between the intermediate medium evaporator (E1) and the LNG evaporator (E2).

Description

technical field [0001] The present invention relates to an offshore floating facility, in particular to an offshore floating facility equipped with an intermediate medium gasifier. Background technique [0002] Conventionally, there is known a gasification device that vaporizes low-temperature liquefied gas such as liquefied natural gas (LNG). As such a gasification device, there is an intermediate medium type gasifier using an intermediate medium (for example, refer to the following patent document 1 and 2). Such as Figure 16 As shown, for example, the intermediate medium type vaporizer 80 disclosed in the following patent document 2 includes: an intermediate medium evaporator 81 for evaporating the intermediate medium stored in the casing 83 by using seawater flowing in the heat transfer tube 84; The LNG vaporizer 82 vaporizes LNG using the gaseous intermediate medium evaporated in the intermediate medium evaporator 81 . In the LNG vaporizer 82 , the gaseous intermediat...

AI Technical Summary

Problems solved by technology

However, since the deck of the hull is located at a high position (for example, 10 m or more) from the sea surface, the power of the pump for pumping sea water becomes large.

Therefore, in an offshore floating facility using an intermediate-medium gasifier, when seawater is used as a heat source medium, there is a problem of high operating costs.
