Objetivo The operation of facilities for transportation and processing of hydrocarbon products is complicated, costly and implies potential risks to man and environment. Thus safe and cost effective operation of these facilities is of key importance for the feasibility of a hydrocarbon production scheme. The goal is to develop and test a real-time computer based system which will improve the techniques for supervision, control, operation and optimization for transportation and processing of hydrocarbon products.The key innovative aspect in the project is the development and application of an integrated dynamic simulator of the entire process and transportation facilities.The project has resulted in the development of a software system which fulfils the overall requirements of improved techniques for on-line supervision, control and optimization of the operation of hydrocarbon facilities based on process simulation.The software system comprises a basic system, denominated LICISS, including a database structure with associated utility programs and a set of I/0 handlers. Furthermore, the system comprises a colour graphics man-machine interface developed on basis of a standard software package, DV-Tools/DV-Draw. Finally, the system comprises dynamic simulators for all relevant components of the facilities for hydrocarbon product transportation and processing.The structure of LICISS facilitates the establishment of a dynamic simulator for the entire hydrocarbon facility and of the specific applications, e.g. supervision, optimization of operation etc., with a minimum of software changes.The software system has been demonstrated by setting up specific applications for three widely different hydrocarbon facilities:- The Tyra East offshore oil/gas processing platform in the Danish North Sea Sector.- The L1. Thorup Gas Cavern Storage Station in Nothern Jutland, Denmark.- A prototype natural gas distribution network.For each of the above demonstration systems, documentation has been prepared in accordance with the Company's standard procedures.The following conclusions have been drawn regarding the main technical achievements of the project:- The project has demonstrated the possibility of improving techniques for on-line supervision, control and optimization of the operation of hydrocarbon facilities with only a minimum of software changes.- The testing of the system using process data from real facilities has been carried out.The central element in the system is the application of a dynamic simulator as basis for the supervision and control of the operations. The simulator can run in on-line mode as well as off-line mode. In on-line mode, the simulator will be driven by real time process data and system state data. In this mode the simulator forms basis for optimization of the operation by calculating current optimum values of set points for the local controls.This is based on real time calculations of the actual fluid dynamic and process dynamic conditions throughout the entire transportation/processing facility. Further, the simulator provides for continuous leak detection and location of leaks, as well as continuous supervision of instruments, equipment and critical points in the facility.In off-line look-ahead mode, the simulator is used for the prediction of consequences of alternative operating strategies. Specifications of the alternative future operating strategies are entered into the simulator by the operator. The simulator then predicts the consequential conditions throughout the facility.In off-line training mode, the simulator will normally work based on a fictive set of initial conditions stored on a dedicated data base.The total system will comprise the following main modules:- Communication Interface: for real-time acquisition of plant data from the conventional Supervisory Control and Data acquisition System (SCADA).- Data Preprocessor: providing a complete and valid set of process data to the simulator.- Simulator: containing a library of physically based mathematical models, e.g. pipelines, separators, heaters/coolers, pumps, regulators, valves.- Applications: handling the results of simulation and providing the dedicated user functions such as planning of operating strategies, optimization, monitoring of "Critical Points", etc.The project has comprised the following main activities in five phases:- Preparation of System Requirement Specifications.This includes definition of the generalized simulator structure, a real-time data base and of the individual element models.- Development and testing of element models.- Design, development and testing of flexible program structure which allows a generalized and easy configuration of the integrated simulator for a wide range of applications using the individual element models.- Development and testing of communication interface module, data preprocessing module and application modules.- Set-up and demonstration of prototype systems for typical transportation/processing facilities. This has comprised well production, subsea flowlines, risers, processing equipment (separators, valves, heat exchangers, compressors, pumps etc.) and related control equipment.
