Process compressors, both reciprocating and centrifugal, are supplied in a packaged configuration, whenever their size allows it. Machine preassembling with its accessories on one or more skids, depending on the size is the preferred arrangement solution. Compressor packaging requires a deep analysis of some special aspects, some of them being in conflict each other, create a real challenge. Pulsation/vibration control, safe lifting, transportation, machinery alignment and ergonomics for maintainability.
CST compressor package design carefully considers all aspects above through a dedicated study of piping support, skid structure, lifting devices, mode shapes, a.s.o.
The supporting skid is of paramount importance for a good package performance in the field. Skid optimization is therefore one fundamental step within CST’s package design process. The best weight/stiffness compromise is done by a combination of the following tools:
