Ship-shore connection system for FSRU and cargo emergency cut-off method of ship-shore connection system

Abstract

The invention discloses a ship-shore connection system for an FSRU and a cargo emergency cut-off method of the ship-shore connection system. The connection system comprises the FSRU, a terminal, a mooring load monitoring system located at the terminal, a mooring load monitoring double-vision system located on the FSRU, an optical fiber connection module, a first electrical connection module and asecond electrical connection module. The first electrical connection module adopts a Pyle-National system, and the second electrical connection module adopts an ITT-Cannon telephone connection system;communication between the FSRU and the terminal takes the optical fiber connection module as a main connection mode, the first electrical connection module serves as an auxiliary connection mode, andthe second electrical connection module determines whether the terminal needs to be connected or not according to the type of the berthed terminal. According to the ship-shore connection system, LNGand CNG can be transmitted between the FSRU and the terminal, and the ship-shore connection system has an electrical connection mode suitable for ship-shore communication in the global market.

Description

technical field [0001] The invention relates to a FSRU communication system, in particular to a ship-shore connection system for the FSRU and a cargo emergency cut-off method thereof. Background technique [0002] FSRU is the abbreviation of Liquefied Natural Gas Floating Storage and Regasification Unit. Usually, the FSRU berthing terminal gasifies the low-temperature LNG in the cabin into normal temperature and high-pressure natural gas through the regasification device on the ship, and transports it to the terminal pipeline network. In case of emergency, FSRU can also directly transfer LNG to the terminal pipeline network. The early FSRU was transformed from an LNG carrier, so the early FSRU was essentially an LNG carrier. When it berthed at the terminal, it used the ship-to-shore connection system of the carrier model, that is, the LNG transmission monitoring mode, and did not introduce Gas transmission monitoring mode. At present, the existing ship-to-shore connection...

AI Technical Summary

Problems solved by technology

[0003] The existing FSRU adopts the ship-to-shore connection mode of the LNG carrier, and there is no case where the FSRU transmits LNG and CNG to the terminal at the same time

Moreover, the electrical connection form of the existing FSRU generally adopts one of the Pyle-National system, ITT-Cannon telephone connection system, Miyaki electrical connection system, and SIGTTO electrical connection system, and there is no engineering case where the two electrical connection systems are used at the same time

For the FSRU whose market application is not clear and has the possibility of global use, an electrical connection system cannot meet the use requirements
