Submersible Vessels House a Desalination System

Tiabzu merges proven subsea technologies of offshore oil & gas and Ocean exploration with desalination by reverse osmosis.  

Modular, Scalable, Globally Accessible

Each module desalinates >1 million gallons of fresh water or 100 cubic meters per day. Fresh water for more than 3,000 households.

Hydrostatic pressure powers reverse osmosis. Hydrostatic pressure” is the difference between surrounding deep ocean pressure and atmospheric pressure maintained using proprietary methods. 40% less energy required as compared to coastal desalination.

Globally Accessible: Patented methods of buoyancy control for deployment and removal facilitate launch using low-cost and common shore-based cranes and launch ramps and small tow-vessels. Also patented are methods for mineralizing at depth for direct delivery of potable water or to create deep ocean water of specified chemistry.

Mobile Operations: Submersible vessels deploy from Purified Water Collection Vessel (Ship or Barge) to supply fresh water to forward operating bases, multiple island, or coastal communities with seasonal, scheduled, intermittent or peak supply, or quick response to emergency or humanitarian needs.


Subsea installation of multiple modules for unlimited volume of fresh water from deep ocean seawater for high population, water constrained regions with coastal drop off to suitable depth, continental shelves, such as California, Mediterranean, Japan, Mideast, and many remote islands.

Out of Site from all Coastal views. Out of Range of All Shipping Traffic.

Awarded US Patent Numbers 10,737,955 and 11,097,962 B2, Bahamas Pat No 2858, Israel Pat No 272545, with other applications pending. Patents address the lifecycle cost and complexities of deployment and module recovery from depth, subsea operation, collection, storage, extraction, and purified water delivery. Claimed is use of naturally occurring ~3% differential in relative density between fresh water produced and ambient saline water as a safe and stable means of buoyancy control. An innovation that lowers cost and risk associated with subsea deployment and removal for maintenance, with applications across multiple offshore sectors, such as lifting equipment or lowering the cost and risk of removal during offshore oil and gas platform decommissioning.
