Abstract: The present invention relates to shallow water subsea desalination system with a subsea desalination template (20) located on a seabed. A retrievable subsea RO-module (4) is located in a subsea RO-module zone (23) of the subsea desalination template (20) and is connected to a RO-module connection. A seawater booster pump assembly (1) includes a seawater inlet (7) and an outlet in fluid connection with a seawater inlet side of the RO-cartridge assembly. A retrievable subsea booster module (2) includes the seawater booster pump assembly (1). A pressure regulator (11) is in fluid connection with a retentate side of the least one retrievable subsea RO-module (4).

Abstract: A subsea desalination template includes subsea desalination module zones and module fluid couplings. A desalinated water outlet is in fluid connection with the module fluid coupling in the subsea desalination module zone. Subsea desalination modules with reverse osmosis cartridges are in fluid connection with a subsea template fluid coupling, a seawater inlet section, and a concentrated seawater outlet section. A transport pump assembly for desalinated water in a pump module is in fluid connection with the subsea desalination template and the desalination modules. A seawater circulation pump is in fluid connection with a seawater side of the at least one reverse osmosis cartridge. A desalinated water pipeline conveys fluid from the desalinated water transport pump assembly to a location above sea level.
