ILF was requested to design a pump station which should be optimized for its intended purpose within the transport system and at the same time suitable for standardisation / repetition.
Standardizing the design does not only reduce engineering and (potentially) construction costs but also maintenance cost and capital spares.
The solution is a modular concept in terms of process design and construction approach. Through a truly construction driven design, it was possible to find a solution where the benefits increase with the number of times the design is repeated.
The design of the piping is such that adding additional pumps does not impact the design of the header for the other pumps. The electrical system and cabling concept is such that its position in the station plot can be easily swapped. The design of the pump suction and discharge areas are made such that it can be grouped in pre-fabricated skids, where all components (piping, valves, instruments, wiring and cables, steel structures, lights, etc.) are assembled and shipped to site where it is almost literally just put in place on the foundations. Last but not least, the pump and driver are placed on pre-cast foundations and transported to site fully assembled.
The benefits of the skid concept are higher in areas with bad weather (complicated site construction activities) and high labour costs. Further, it is better the bigger the skid is (more components can be placed on it). Although the size is limited by transportability, the approach is applicable almost everywhere. One must keep in mind the example of pump and driver, which are also normally mounted on a skid and transported to site.
The described solution is currently in development and will be applied in the near future.
