Design and implementation of a 2.500m offshore seawater pumping system for high-tech aquaculture in Ba Ria - Vung Tau, Vietnam

Tóm tắt

This study focuses on the design and implementation of an offshore seawater pumping system to support high-tech aquaculture in Dat Do District, Ba Ria - Vung Tau Province. This is the first application in Vietnam of a seawater pumping system that draws clean water directly from a 2.500m offshore distance without an intermediate reservoir, providing stable salinity levels and minimizing pollution risks. The system uses a dual-suction centrifugal pump made of SUS316 stainless steel, paired with a large-diameter (1.200mm) HDPE pipeline of significant length, meeting requirements for pressure loss, pressure, and corrosion resistance in seawater environments. Experimental results show that the system reliably supplies 110.000 m³ of seawater per day to a 300-hectare farming area. The results confirm the feasibility and high efficiency of the pumping system, meeting water supply requirements with suitable head and flow rate under real-world conditions.
