For years, the offshore industry faced a hard truth: Existing marine screens and silt curtains could not survive extreme offshore conditions. High energy waves, strong currents and long-term exposure pushed conventional systems beyond their limits.
Nowhere was this more evident than in the open ocean.
Between 2015 and 2017, The Ocean Cleanup tested multiple screen and barrier prototypes in some of the harshest marine environments on the planet. These included the North Sea, the Pacific Ocean and the Great Pacific Garbage Patch. Every solution tested failed. Internally, these setbacks were referred to as Unscheduled Learning Opportunities.
At the time, many industry experts believed a solution simply wasn’t possible.
At the end of 2017, Ecocoast partnered with The Ocean Cleanup to take on that challenge.
Within a period of 6 months, we had successfully designed and manufactured a screen that:
✅ Passed the rigorous tests in the North Sea;
✅ Withstood the Pacific trials;
✅ Performed in the extreme conditions in the Great Pacific Garbage Patch.
This had never been done before. And industry experts thought it was impossible. It marked the first time a flexible marine barrier system had successfully passed all three environments.
The partnership was recognized by The National and Gulf News among others, highlighting the innovation and engineering behind the project.
This experience became the foundation for our strongest, most advanced turbidity mitigation solution to date:
Type V Ecobarrier® Silt Curtain (ESC-750)
Engineered for long-term and permanent deployment offshore in the most challenging conditions.
✅ High-energy offshore environments;
✅ Strong currents and wave action;
✅ Large-scale dredging, subsea and offshore construction projects;
✅ Situations where standard silt curtains repeatedly fail.
We are proud to add another first to our list of marine innovations with this newly engineered type of silt curtain. Type V is not an incremental improvement. It represents a new class of offshore silt curtain, developed using the same engineering principles proven in open-ocean conditions.
The timing of the introduction of our Type V coincides with the boost in offshore and subsea construction projects, the shift towards sustainability in the dredging industry (see CEDA’s report). At the same time, the increase in government policies is driving the need for high-strength, durable offshore marine protection barriers.
Projects are getting bigger. Conditions are getting tougher. And expectations for environmental performance are higher than ever.
This means an exciting time for us at Ecocoast. Type V Ecobarrier Silt Curtain is another step forward in designing entirely new marine solutions that were thought impossible. It allows us to support and protect the ever more ambitious marine projects around the world.
By utilizing the latest technology during the design and production process, from our Marineforce software to our automated manufacturing equipment, we are geared up for advanced engineering. This allows us to continue designing high-strength, engineered marine barriers to perform in the most extreme marine environments.
Type V represents another industry first for Ecocoast. And a clear statement of what’s possible when engineering, manufacturing and environmental responsibility come together.

Type V Ecobarrier Silt Curtain (ESC-750) is widely considered the strongest marine barrier globally. Unlike Type III or IV curtains, the Type V was specifically engineered by Ecocoast to withstand the high-energy conditions of the Great Pacific Garbage Patch and the North Sea. It is designed specifically using proprietary Marineforce design software to handle extreme wave heights and currents that typically cause generic barriers to fail.
After multiple "Unscheduled Learning Opportunities" (prototype failures), The Ocean Cleanup partnered with Ecocoast in 2017. Ecocoast successfully designed and manufactured a high-strength screen that survived the most rigorous offshore trials in history. This partnership validated the Type V technology as the only solution capable of 100% containment in deep-sea, long-term deployments.
Ecocoast offers a full range of engineered silt curtains, designed for extreme offshore environments. Our barriers can be deployed for long-term or permanent use, and are customized to turbidity mitigation, dredging and coastal protection projects worldwide.
Yes. Our team provides end-to-end solutions, from design and manufacturing to installation, relocation and maintenance of silt curtains for both coastal and offshore projects. We have experience with high-energy environments, ensuring your project complies with environmental regulations and sustainability standards.
