How is America's Biggest Dredge Saving $100 Billion in Trade?

Something beneath the surface of the Houston Ship Channel threatens to shut down one of America’s most important waterways.

It’s not a storm. It’s not pirates. It’s mud.

Every year, millions of cubic yards of sediment settle into the channel, threatening to block the cargo ships carrying nearly $100 billion worth of goods, oil, gas, and materials through Houston. And if shipping stops… the modern world feels it.

Enter the DB Catalina — the largest mechanical dredge in the Western Hemisphere.

In this video, we go onboard this floating monster to see how it keeps the channel open 24/7. With a 100 cubic yard bucket weighing up to 360,000 pounds when full, the Catalina removes thousands of yards of mud every shift while massive cargo ships pass only feet away.

Along the way, we break down:

• How dredging keeps global shipping moving
• How the Catalina “walks” across the channel floor using massive spuds
• The enormous dredge and power systems that run the operation
• How crews work and live onboard for weeks at a time
• And what it takes to remove over 8 million cubic yards of material from one of America’s busiest waterways

This isn’t just a crane on a barge. It’s one of the most important machines in American commerce.

A huge thanks to Curtin Maritime for giving us access to this incredible operation.
