Project critical path and deriving requirements for Engineering

Baron, Herve Large complex projects entail a high number of highly inter-related activities. One must be able to stand back, identify the priorities and attend to them. Even though each project has unique features there are repeating patterns. The critical path and show stoppers are always the same, in particular Information from Equipment vendors and…

Pipe Supports. Functionality, selection requirements and importance of high quality pipe support elements

Bittorf, Frank In order to allow thermal movement of a piping system and save the piping system from unplanned movements, different types of flexible pipe supports and safety elements are needed, mainly Constant supports, variable supports as well as rigid struts and shock absorbers. This seminar will explain in detail the different working principles, technical…

Impellers arrangement analysis and related design impacts on double stage centrifugal fan for Oil & Gas applications.

Graziano, Vimercati In recent Oil & Gas mega projects we experienced increasing requests for centrifugal fans operating in severe duty conditions with constraints related to limited installation areas, being the plant layouts already decided and frozen at project early stage. Therefore, the selection of the most adequate rotating machine became more and more sensitive in…

How can one know whether stub-in/stub-out or fitting connection is required or not for branch connection & in fitting type whether one should go with Tee or o’let?

Stub-out is not a correct term, this should be stub-on. Functionally if you are the piping layout designer doing piping layout then you use the information supplied on the “Branch Selection Tables” provided by the Piping Material Engineer (PME) in the Line Class specs. Functionally if you are the PME developing the “Branch Selection Table”…

Reducing Space in Offshore applications for Centrifugal compressors

Banchi, Nicola High Pressure Ratio Compressor (HPRC), it is a new type of compressor architecture that aims to increase the compression station compactness by reducing the number of compressor bodies, in particular for offshore markets provides a great benefits reducing weight, minimizing footprint and installation time. GE’s HPRC technology is based on an innovative architecture…

Nozzle Design, the weak point in every Pressure Vessel

Tirenti, Javier To attach a nozzle in a pressure vessel, it is necessary to make a hole in the shell or head body in question. When making this hole, an area of the vessel is being “taken away”, therefore stress paths are going to divert tangentially to the hole. Thus, we must “substitute” the removed…
