Liquid cargo management system for ultra-large oil tanker

Abstract

The invention relates to a liquid cargo management system for an ultra-large oil tanker. Two network exchange boxes and a management type network switch arranged in the data processing cabinet form aredundant Ethernet ring network; and the two workstations are connected to the Ethernet ring network and are in a hot backup state. Two redundant data processing units and a plurality of gateway servers are arranged in the data processing cabinet, the gateway servers are connected with the liquid cargo subsystems respectively, the real-time signals of the liquid cargo subsystems are uniformly converted to MODBUS-TCP signals, the MODBUS-TCP signals are transmitted to the data processing unit, the data processing unit receives a workstation command to control liquid cargo subsystem equipment inreal time, and the functions of cargo oil loading and unloading monitoring and equipment protection can be achieved. A safety router is arranged in the data processing cabinet at the same time and used for receiving the loading scheme sent by a loading computer, and meanwhile, real-time data of the liquid cargo system can be published to the outside through the safety router. The liquid cargo management system can ensure high real-time performance, high stability and high safety of a VLCC liquid cargo system.

Description

technical field [0001] The invention relates to a data management system, in particular to a liquid cargo management system for super-large oil tankers. Background technique [0002] VLCC is the abbreviation of Very Large Crude Carrier. The liquid cargo system in VLCC is a complex and huge system consisting of many subsystems, such as cargo oil pump and ballast pump system, liquid level monitoring system, valve remote control system, and combustible gas monitoring system. , ballast water system, inert gas system, oil gas recovery system, oil discharge monitoring system, etc. Currently, each subsystem in the cargo control room of the VLCC is independent of each other, and there is no data interaction between the subsystems, lacking a comprehensive data processing capability The intelligent management system is used to handle the complex logical relationship between various subsystems. Moreover, the communication interface forms and protocols of each subsystem are diverse, an...

AI Technical Summary

Problems solved by technology

The crude oil loaded by VLCC is flammable and explosive. During loading and unloading, a single point of equipment failure may cause cargo oil to escape, leak and drip, which will not only cause environmental pollution but also cause fire and explosion, threatening the safety of the ship.
