System Rornet has a very strong and proven calculation engine which ensures quick, accurate and stable calculations. The System Rornet program suite has been developed over a period of more than 35 years and has proven its worth in a significant number of well-performing networks.
One of the key functionalities of System Rornet is water hammer analysis to predict problems and design safety measures. With this analysis it is possible to protect the network against major and expensive damage related to for example pump failure or sudden closing of valves in future operations.
System Rornet modules
System Rornet is module based, which enables the users to perform advanced analyses at maximum efficiency.
The hydraulics module determines the steady state pressure and flow fields for any network containing a liquid. The module is certified by Det Norske Veritas (DNV).
The heat flow module determines the steady state heat balance and the temperatures in the network.
The gas flow module determines the steady state pressure and flow fields for any network containing a gas.
The steam flow module determines the steady state pressure, temperature and flow fields for any network containing saturated and overheated steam with pressures and temperatures below 20 bara and 300°C respectively.
The design module is used for design of new networks as well as extension or refurbishment of existing networks. Combined with either the hydraulics module or the gas flow module, the optimum dimensions of the pipes in the network are determined.
The water hammer module performs transient hydraulic analysis. Water hammering is caused by any change in the supply pattern, e.g. pump failure or valve closure. Control of valves and pumps is taken into account. The module is certified by Det Norske Veritas (DNV).
The heat hammer module performs dynamic analysis of temperature fields. The heat storage capacity of the network is taken into account, and the effect of varying fluid temperatures is simulated with respect to the physical and economic consequences.
The production simulation module calculates how the production is distributed among the production units. The calculations are based on the properties of production units and networks (e.g. heat demand variation hour by hour, hydraulic bonds, minimum and maximum load on production units, revision and breakdown of production units).
