Abstract

The invention relates to the technical field of water refueling, in particular to an LNG fuel water refueling control system. The LNG fuel water refueling control system comprises a refueling controller, an electric control cabinet of a central control room, a signal collecting junction box, an electromagnetic valve control box, a field equipment branch control cabinet and a field signal transmitter junction box, wherein the refueling controller and the electric control cabinet of the central control room are arranged in the central control room; the signal collecting junction box, the electromagnetic valve control box, the field equipment branch control cabinet and the field signal transmitter junction box are arranged in an operating field; relevant parameters of the LNG fuel device arepressure P and temperature T. The control units in the field equipment branch control cabinet are independent, and the field equipment branch control cabinet can be flexibly arranged according to different control demands of the LNG refueling device, so that the LNG fuel water refueling control system can be suitable for ships of more specifications.

Description

technical field [0001] The invention relates to the technical field of overwater filling, in particular to a control system for overwater filling of LNG fuel. Background technique [0002] Based on environmental protection and water resources protection, driven by relevant national policies and measures, the use of LNG fuel for inland ships has gradually formed a large scale, and LNG fuel replenishment (filling) for transport ships is a bottleneck problem that needs to be solved urgently. [0003] The construction of bunkering pontoons is restricted by many factors such as hydrology, channel, wharf, supply, and service requirements. The specifications, structures, and processes of the bunkering system vary greatly. Most of them can only be built on a single ship or in small batches. It is easy to disassemble, and each part can be controlled independently to adapt to the use of more types of ships. [0004] At present, inland river LNG refueling devices (ships) are mostly bu...
