Project Overview
This oil depot is a strategic repository of Ghana.The supervisory party is the Indian International Supervision Company.The reserve has a total of 12 oil storage tanks.Five are inner floating roof tanks and seven ordinary vault tanks,The total capacity is: 119,000 cubic meters.There are three intermediate tanks for unloading transition.Each tank has a capacity of 100 cubic meters.There are 6 groups of unloading cargo platforms.There are 12 loading arms.
System structure Introduction
The entire system uses an open, distributed system architecture.Do "distributed control, centralized management, information sharing",The monitoring management system specifically includes:
Tank capacity measurement subsystem
Using EMERSON's high-precision radar level gauge,High static pressure transmitter,Multi-point thermometer and TANKMASTER tank capacity calculation software.
Data acquisition and monitoring management subsystem
Using the GE PAC 3i controller and its process I/O set,2 sets of upper computer system,Use GE CIMPLICITY HMI industrial configuration software.
Process control instrument
Adopting domestic top electric cut-off ball valve,3051 transmitter,E+H tuning fork level switch,French FM spiral wheel flowmeter and so on.
Fire alarm subsystem
The fire system adopts Beijing Lida fire alarm button and controller,The flammable gas alarm system adopts Shenzhen Tean Company ES2000 series products.
Transceiver monitoring and management subsystem
Adopting Hongyi AWZC series loading management system and its software,On-site equipment includes:French FM loading flowmeter,EMERSON 788 electro-hydraulic CNC valve,Overfill Grounding protector.etc
Network and remote service sharing system
Data monitoring data transmission to the production management office and customs.
System screenshot
The system is closely integrated with the automatic control of the tank area.And can display the liquid level, temperature and even pressure changes of the tank in real time in the form of a graphical interface:
Tank map
The tank zone partition map can display the corresponding parameters of the zoned tank in real time.And the corresponding production operations can be performed on the partition:
