INTEGRATED WEB-BASED IOMS SYSTEM FOR OPERATING AND MANAGING MOVEMENTS IN TANK FARMS

摘要

The iOMS (intelligent Oil Movement and Storage) application is used to monitor and control thernmovement of raw materials, intermediate products, and final products within a tank farm orrnsimilar facility. It automates blends, transfers, water drainage, shipments and receipts. It alsornsupports advanced features like dynamic path searches for new tanks at the beginning of tasksrnand for swing tanks during the execution of tasks. Additionally, the product supports thernexecution of perpetual tasks for both the continuous receipt of feeds and the continuous shipmentrnof products with automated tank swings requiring minimal operator actions.rnThe server engine is based on ABB’s object oriented AiEM? engineering platform. AiEM? isrnbased on Gensym’s G2 software product that inter-operates in a client-server relationship. Thernserver can interface with any DCS/SCADA system that has an OPC server available. This DCSrnplatform independence is one of the major advantages of the application. The application gets allrntank related data as well as equipment status information using OPC subscriptions. Additionally,rnthe engine supports the ability to subscribe to COM events which provides the capability torninterface with standard Refinery/Tankfarm Databases such as LIMS and TIMS.rnThe iOMS client operator station is the tool used by plant operators for creating and managingrntasks for material movements. The operator interface is web-based. Operators use Microsoft?’srnInternet Explorer to access operator displays. Operator stations communicate with the server viarnan ActiveX Bridge. This software design architecture of the system (i.e. web-based clientrnapplication) provides the capability for any user, with proper security authorization, tornmonitor/control the operation of a tank farm via an engineering and/or operator station from anyrnremote location. The sequences generated for the executing tasks are downloaded to thernDCS/SCADA system for execution using an OPC/COM based Sequence Table Processor (STP).rnAdditionally, the server is linked to a relational database (e.g. ORACLE~?) for hot and coldrnsystem restarts as well as for providing data to a variety of reports. This data can easily be sharedrnby other plant applications like a Data Reconciliation System if required.rnThe iOMS application has been installed in two existing crude oil terminal facilities and isrncurrently being installed in a 120-tank refinery tank farm.
