Detailed Engineering Services

ImageGrafix can perform analysis for the hydraulic system to be more optimized to its purpose, to improve its safety and to cost less money. Typically the services include: – Determining the maximum flow capacity of a system (e.g. ship/ shore cargo transfer). – Advising on pipeline routing and elevation profile. – Optimizing the pipe diameter by calculating flow, pressure and velocity of fluid in the pipeline. – Optimizing the Pump Size by calculating pumping costs vs. Pipeline diameter for typical pipe materials. – Specifying surge suppression equipment to improve both the peak pressures and the overall operability of the pipeline. For example, determining the check valve size, type and dynamic performance needed to prevent check valve slam. Or specifying the best location for air valves and their sizing.

ImageGrafix is a regional leader in surge analysis and dynamic simulation. Have performed services for all the major oil companies and consultants in the Middle East region. Every study provides the simulation results with our observations, scenarios recommendations and conclusions, thus our recommendations are of an independent company who offers unbiased advice on design and equipment selection. Simulation and surge analysis give a wide range of benefits during design and operation. Once the computer models are built they can be used throughout a project’s life.
