Dynamic simulation is a proven tool for successful engineering services from design validation during Front End Engineering Design (FEED) all the way through to decommissioning of full process plants.
Our simulators use full multi-component thermodynamic mathematical modelling with a high level of precision. Typical independently verified results compared between the calculated and measured values for a thermodynamically active gas and oil systems are within better than 2% of values for all flow, level, pressure, temperature instantaneous values around a significantly large plant.
This level of accuracy has allowed us to verify systems that include over half the UK National Gas Transmission major compressor stations, and to verify the plant operations and control systems around the £600m high-activity liquor evaporator for British Nuclear Fuels at Sellafield.
With a loop speed of under 20 milliseconds for most models, the response time of our dynamic simulators allows their use in extremely dynamic studies, including for pressure relief and blowdown systems verification, and in compressor surge prevention studies.
TSC Simulation provides a complete model build and analysis service through planning and design phase to provide operability validation studies.
Our first set of dynamic simulation and operability validation studies was in 1999, for three UK National Gas Transmission Stations on behalf of AMEC Capital. The project involved validating the control and safety systems of each compressor station.
TSC have since supplied the dynamic models and carried out the performance studies for 18 of the compressor station upgrades and gas storage solutions on the UK Gas National Transmission System (NTS).
Our simulators use full multi-component thermodynamic mathematical modelling with a high level of precision.
Optimisation of vessel sizes, valve sizes and heat exchanger capability is often based on the dynamic peaks and minimums of flow and level, for which precise dynamic simulation will find the optimum solution. The dynamic peaks and minimums of flows and levels are often defined by the individual components of the fluids as their phases change with temperature and pressure through the plant. Pressure safety items are especially dependent on the dynamic response of the fluid components.
The optimum and safe running of process plant is defined by the capability of the Instrumentation and Control philosophy.
Complex and advanced control loops may be modelled and may be tested with an accurate dynamic simulation of the process, with huge savings in commissioning time.
Especially with plant items such as compressors, the anti-surge protection system may be modelled using algorithms from major suppliers such as CCC. We have years of experience and a multitude of examples where such systems have been tested, optimised and verified even prior to final designs being fabricated.
Our simulators are used for start-up and shutdown procedure optimisation in some of the largest process systems in the world, based on accurate modelling of the instrumentation and control systems in addition to that of the process.
With this cross fertilisation of capability between engineering and training, the TSC system is perfectly geared to the provision of Life cycle, Multi-Purpose Dynamic Simulators
This capability has been used across several sectors. Not just in the Oil & Gas industries, but as one example an engineering design study conducted for a major nuclear facility for Sellafield in the UK found a potential dynamic operability weakness that was then optimised out before final commissioning, saving huge costs for the project.
This project concluded with the use of the simulator to create the optimum operator GUI screens and later used as the training system for the operatives.
