In 1977, Saudi Arabia proposed towing massive Antarctic icebergs to the Arabian Peninsula to solve chronic water shortages.
The Logistics of Towing Icebergs
The proposal, championed by Prince Mohammed Al Faisal, envisioned using heavy-duty tugboats to haul icebergs across thousands of miles of ocean. The goal was to create a floating reservoir that would provide a sustainable source of fresh water for the desert nation, while potentially altering the microclimate of coastal regions.

To prove the concept, scientists transported a two-ton chunk of the Portage Glacier in Alaska to an Iowa university using a combination of helicopters, aircraft, and refrigerated trucks.
Technical Barriers and Environmental Concerns
Engineering experts identified significant hurdles that ultimately rendered the project economically and technically unfeasible. Army Cold Regions Research and Engineering Laboratory noted that once a vessel crosses the equator, the risk of the iceberg melting away to nothing but a “seawater-soaked rope” becomes extreme. Beyond the mechanics of towing, researchers raised alarms regarding the potential for massive environmental disruption. Tethering an iceberg near a coastline would likely cause significant fluctuations in ocean temperatures and damage local marine ecosystems.
Why Water Scarcity Projects Remain Relevant
Saudi Arabia’s interest in the 1970s was driven by the high cost of existing desalination technology. While the iceberg project was abandoned due to prohibitive costs and technical uncertainty, the search for creative water solutions persists. Modern water management relies heavily on advanced desalination, but as climate change intensifies, the concept of harvesting glacial runoff or moving ice continues to surface in scientific discourse. However, no large-scale project of this nature has been successfully implemented to date.
Frequently Asked Questions
- Why did Saudi Arabia want to move icebergs?
The country sought a cost-effective alternative to expensive desalination processes to address severe fresh water shortages. - Was the project ever attempted on a large scale?
No. While a small test was conducted to demonstrate the viability of transporting ice, the full-scale project was deemed too costly and technically risky. - What are the main risks of moving icebergs?
The primary risks include rapid melting during transit, the need for immense towing power, and potential environmental damage to coastal ecosystems.
