Description
Technical Field
The invention relates to an FSRU communication system, in particular to a ship-shore and ship-ship connection system for an FSRU and a cargo emergency cutting method thereof.
Background
FSRU is a short term for lng floating storage and regasification units. In general, the FSRU berthing terminal gasifies the low-temperature LNG in the cabin into normal-temperature and high-pressure natural gas by a regasification device on the ship, and transmits the natural gas to the terminal pipe network. In emergency, the FSRU may also directly transfer LNG to the terminal network. Early FSRU was modified from LNG ship, so early FSRU is essentially LNG ship, when it is berthed to terminal, the ship-shore connection system of transport ship mode, i.e. LNG transfer monitoring mode, is adopted, and gas transfer monitoring mode is not introduced. Currently, existing ship-shore connection systems mainly include three modes of optical fiber, electrical and pneumatic connection, i.e., at least two of the ship-shore connection modes are generally selected. The pneumatic connection system is a shore connection system on an LNG ship at early stage, is directly connected to an air safety system of the ship through an air hose, and is mainly used as a standby mode of optical fiber connection and electrical connection at present. The electrical connection is divided into Pyle-National system, ITT-Cannon telephone connection system, miyaki electrical connection system and SIGTTO electrical connection system, currently Pyle-National system occupies the main market, has perfect functions and can simultaneously transmit voice, cargo emergency cut-off system (ESD) signals and mooring (MLM) data; the other three electrical connection modes can not transmit mooring data; whereas ITT-Cannon telephone connection systems are mainly used in japan, taiwan, where only voice can be transmitted. Current shore connection designs typically employ one of the electrical connections.
When the conventional FSRU performs three-party linkage operation of the ship and the ship, two sets of connecting systems, namely a ship-to-shore connection system and a ship-to-ship connection system, are adopted, the two sets of systems independently operate, the systems are complex and redundant, a unified control center is not provided, information exchange and processing of the three-party linkage operation are inconvenient, and the management difficulty on the FSRU ship is increased. At present, no clear regulations are made on the signal types and contents of FSRU shore and ship connection systems in the case of three-party linkage operation in international organizations such as sigto and IGC.
The prior FSRU adopts a ship-shore connection mode of an LNG ship, the LNG mode and the CNG mode of the FSRU are not considered at the same time, and the prior ship-shore connection design cannot play a role in communication very normally under the condition that the FSRU transmits LNG and CNG to a terminal at the same time. The existing FSRU generally adopts one of Pyle-National system, ITT-Cannon telephone connection system, miyaki electric connection system and SIGTTO electric connection system, and no engineering case that two electric connection systems are used simultaneously exists. For a FSRU with ambiguous market application, there is a global possibility of use, and an electrical connection system does not meet the use requirement.
Therefore, there is a need for an electrical connection method that can realize three-way linkage operation communication between the FSRU and the LNG ship and the terminal, and that can transfer LNG and CNG between the FSRU and the terminal, and that is suitable for the shore communication of the global market.

As shown in fig. 7, the third electrical connection module employs a Pyle-National system, which includes a fifth electrical port 430 located on the FSRU110, a sixth electrical port 440 located on the LNG ship 150, and 37 channels (37 channels are not shown in the figure), and both ends of each of the channels are connected to the fifth electrical port 430 and the sixth electrical port 440, respectively. The third electrical connection module does not transfer CNG information between the FSRU110 and the LNG ship 130.
Fig. 8 shows a communication schematic diagram of the fourth electrical connection module, which is the same as the second electrical connection module, and thus will not be described again.
