The Study For Centrifugal Pump Selection In Designing And Building Offshore Units

The reasonable selection of centrifugal pump is a very significant topic in basic and detail design for offshore projects and vessels. Experienced shipyards and engineering company would always emphasize on this topic. In case of any mistake or fault, the selected pump would often has to be selected once more, with the former abandoned, which will make significant waste of money and project building schedule. Because the offshore unit is a high assembly of various equipments, complicated configurations and complete functions, the parameters of centrifugal pump would often be in close connection with the whole unit. So the requirements of selecting proper pumps would be highly significant for the engineer's experience and designing background. This article would emphasize on this topic, taking the actual practice in shipyard, based on proper theory, trying to find out a series of proper methods or theories to make a scientific guide for shipyard and engineering companies.This article would take centrifugal pump's basic configuration and working philosophy as beginning, deeply study the selecting method of various key parameters while selecting this equipment and analyze the actual condition of pump connection piping stress in association with the relative applicable software. Finally three actual offshore projects would be taken as examples to verify the rationality of the mentioned theories, with the target to find out one set of reasonable methods while facing this topic and fulfill this article's study intent ultimately.
