NSF'S OFFSHORE TEST SITE: Igniting Innovation for a Sustainable Tomorrow 


Why the OTS? Fueling Change Through Action 

In our pursuit of a positive climate impact through seaweed, we realized the crucial need for Multi Use in the seas and a dedicated space to trial groundbreaking innovations to do so. The result? The OTS – potentially 'your' testing ground for transformative ideas amidst the challenging reality of offshore conditions. 

Better yet.. Why the OTS for you?  

Instead of investing your most valuable resource, time, into many things like permitting and what not, we will make sure those distractions are taken away from you, so you can focus on your core business, if it's seaweed or our testing floating solar panels.  

What is the OTS? 

Imagine a space 12 km off the Scheveningen coast, a vast 6 km² expanse dedicated to incubating start-ups and scale-ups. This is the OTS, an innovation hub challenging the boundaries of what's possible, perfectly suited to validate your innovations in the real-world, pushed by the limits of the offshore environment from the North Sea. 

What does the OTS Offer? 

The OTS is not merely a location; it's a licensed testing ground in the North Sea, safeguarded 24/7 by Royal Dirkzwager. Dive into possibilities with on-site diving and underwater investigation capabilities. Collaborate seamlessly with North Sea Farmers, bringing over seven years of OTS experience. Enjoy a fishing-free zone for safe testing, cost-sharing options for logistics, essential vessels for material transport, and access to Svasek's weather forecasting model. As OTS member we aid you in knowledge sharing, helping the multi-use offshore sector in utilizing the lessons learned more efficiently. Furthermore, as member and integral part of the North Sea Farmers network, your innovation receives unparalleled exposure.  

How to Utilize the OTS? Your Exclusive Canvas for Creativity 

The OTS is exclusively designed for our community of innovators. It's not just a space; it's a secure 6 km² environment where the largest plots are 1km² and can be tailored for piloting new solutions. Can we answer the how to use the OTS in a concrete way? The short answer, No, because every multi-use project we host is unique so we need your input. Help us, help you. This should be nuanced though, some things are standardized, but are better to be discussed in our onboarding procedure. Furthermore, we have experience with an array of vessels, anchoring methods, you name it. We will guide you onto the OTS.

Your ideas, nurtured by the vastness of the North Sea with our support, ready to reshape the future. Get in touch! 

Interested in Testing Your Solutions?

With our Waterwet permit valid until December 31, 2028, we offer a field lab specifically designed to accelerate sustainable multi-use projects. For inquiries contact Lennard, the OTS manager. Together, let's shape the future! 



Meet Lennard, our OTS-manager and our expert when it comes to innovation in an offshore environment. He manages the activities at the OTS on a daily basis.

Lennard underlines the necessity of testing in offshore conditions:


Lennard elaborates on the great possibilities the OTS has: 

"We need a combination of leaving nature alone and innovating how to use the ocean in a sustainable way. The Offshore Test Site is where this comes together and where I can bring the right parties together to make the necessary changes."

Lennard will be your point of contact when running a pilot at the OTS. He will guide you through the process from beginning to end. Not only will she provide technical support, but she has a great portion of positivity, helping you through the sometimes challenging days!

Our Offshore Test Site is situated 12 km away from the Scheveningen coastline. While the location may intrigue you, it's worth noting that the majority of the infrastructure is submerged, with only a handful of buoys visible on the surface. Therefore, while the idea of a visit might seem appealing, there's currently not much to visually experience at the site.
