Profile: CEDCS Ltd. is a chemical engineering service provider. We focus on chemical process industry and related applications. We specialize in issues like hazard studies, water hammer and safety integrity level. Our services include research, design, development and the operation of plants. Water hammer is a shock wave sent through a pipeline caused by a sudden or rapid change of flow rate. This shock can have catastrophic results from ruptured pipes, damaged supporting structures to loss of material. We carry out water hammer analysis work by using highly effective modeling software typically Flowmaster for more complicated systems and HiTrans for simpler systems. We develop software to deal with some of the external data processing required to set up water hammer models and to understand the results. We have developed safety integrity levels or process industries.
