Abstract The design of seawater intake pumping station in a marine infrastructure project in Saudi Arabia and the purchase of the seawater intake pumps for the station should comply with the standard API 610 of centrifugal pumps for petroleum, petrochemical and natural gas Industries. In bid documents of the project owner, the seawater intake pumps are subject to 55 000 m3/h capacity and 16.1 m head at the duty point. However, the transformer capacity is insufficient for the power required by the pumps; meanwhile the quoted price for the pumps is slightly lower, presenting a business risk for potential contractors based on a thorough analysis of the documents. To avoid this risk, the variation of seawater level in the intake is analyzed and the intake is optimized, further the capacity is altered to 50 000 m3/h for pump selection. After the selection is optimized, the selected mixed-flow pumps with diffuser can operate in a range of flow rate of 50 000 to 59 100 m3/h at a higher efficiency of 85% to 87%, showing the transformer capacity is satisfactory. At the same time, the optimized pump should be in integrated structure rather than in pull-out one.
