14. 14 Pipeline Monitoring – Dumbarton to Piper Bravo Talisman Energy A complex gas export and allocation problem solved with a very inexpensive solution XPLORE Experience Project scope >Originally MacCulloch dense phase gas exported to Piper B platform >Limited liquids handling facilities on Piper B >New Dumbarton export gas tied into MacCulloch line subsea >Dumbarton gas changes the composition of the gas fed to Piper B, hence less headroom before two phase region is reached >XPLORE system scope is to monitor entire gas export systems from Dumbarton and MacCulloch, subsea pipelines and Piper B arrival system >Model the system and predict the arrival composition at Piper B and hence the volume of liquid handling required >Alert operations to any potential problems and recommend operational changes >Provide allocation of gas to determine MacCulloch and Dumbarton gas sales Key features >System modelled entirely in HYSYS >XPLORE connected to three different control systems / data historians >Multiflash thermo package used to improve accuracy >Predicative mode enabled to show operator future composition arriving at Piper B >Very accurate gas allocation as a full mass balance is completed every time step

15. 15 Pipeline Monitoring – Shell FLAGS system Shell The challenges of modelling a large multiphase system and predicting arrival conditions accurately overcome XPLORE Experience Project scope >Shell FLAGS 36” trunkline takes gas from a number of North Sea platforms and routes it to the St. Fergus gas plant for processing >Pipeline operates in the two phase region >New gas tying into the trunkline from the Norwegian sector (Tampen and Vega) >New gas is more dense, hence higher liquid rates and liquid holdups to be processed at St. Fergus >St. Fergus gas plant process and process control system not capable of handling large liquid slugs >XPLORE system to provide the operator with an overview of the entire system and a prediction of MW and liquid rate arriving at St. Fergus (line is >400km therefore operator can get 12+ hours of notice) >Alert operations to any potential problems and recommend operational changes Key features >System modelled dynamically in UniSim and Compas >XPLORE takes data from >20 control systems, data historians and SCADA systems >XPLORE centred on the onshore central control system (ACCC) >XPLORE has become the central dashboard view of the entire FLAGS system

16. 16 Compressor Monitoring – Alwyn Export Compression Total Multi-stage, multi-train compression export system with variable suction conditions due to multiple tiebacks XPLORE Experience Project scope >Monitor two parallel, variable speed centrifugal compressors and associated gas turbine >Give users access to powerful operating data not available through the DCS (Distributed Control System) Key features >System provides real-time visualisation of compressor operating maps, increasing ability to optimise process >Translates CCC anti-surge control lines enabling troubleshooting and a quick reference for spare capacity identification >Turbine monitoring presents key process information and enables calculation of environmental emissions >System also provides crucial information for optimisation of new load sharing control system
