Worldwide the need for seaweeds is growing and will keep on growing. This opens unique opportunities for sustainable growth of the aquaculture sector in the North Sea region.

Over the past years several small/medium-scale seaweed cultivation projects took place at nearshore locations along the North Sea. Large scale seaweed cultivation at an offshore location however was not realized yet.

The WIER & WIND project targets mechanized seaweed cultivation at the hectare scale in an offshore wind park in the Belgian part of the North Sea. Apart from the technological challenges, WIER & WIND also promotes multi-use of space in offshore wind parks. An experienced and multi-disciplinary team of partners, being AtSeaNova (project coordinator), Seaweed Harvest Nordsea, Murre Technologies and GeoXYZ, Foundation North Sea Farm, University of Ghent and HZ University of Applied Science will design, deploy and operate the 1-2 ha seaweed farm at the offshore location during this 3 year project (July 2019 – June 2022).


-Dutch Summary-


De wereldwijde vraag naar zeewier is groot en zal de komende jaren verder groeien. Dit biedt een unieke kans voor duurzame groei van de aquacultuursector in de Noordzee regio.

In de afgelopen jaren zijn er meerdere kleinschalige zeewierinitiatieven opgestart in het Europese kustgebied, met name dichtbij de kustlijn. Grootschalige teelt van zeewier is echter nog niet mogelijk met de huidige stand van teelttechnieken.

In dit project willen bedrijven Seaweed Harvest Nordsea, AtSeaNova, Murre Technologies en GEOxyz de productie van zeewier significant verhogen. Het zeewiercollectief Stichting Noordzeeboerderij en kennisinstellingen Ugent en HZ University of Applied Science zullen hen hierin ondersteunen. Gezamenlijk zullen de partners een grootschalig en geautomatiseerd zeewierteeltsysteem ontwikkelen dat betrouwbaar is op zee, en dat kan worden ingezet binnen de vele windmolenparken die de Noordzee rijk is. Het project draagt hiermee bij aan meervoudig ruimtegebruik van de windmolenparken. WIER & WIND is een 3-jarig project dat loop van juli 2019 tot juni 2022.

A new stage has begun

December 11, 2018

From now, AtSea Technologies is part of HoldiNova group, a business holding company specialized in the marine system protection and collection of algae, and changes its name to AtSeaNova.

On 2018 AtSeaNova focused on the development of new devices and boats allowing to work on industrial seaweed farms of large scale on several hectares.

Three directions for AtSeaNova devices

December 10, 2018

On 2018 AtSeaNova focused on the development of new devices and boats allowing to work on industrial seaweed farms of large scale on several hectares.

NovHarvest 501 a barge of 12×8,5m equipped with hydraulic systems for seeding, harvesting seaweed and cleaning the substrate on the field. This machine moves on the row with hydraulic driven wheels.

Seaweed farming working boat

NovaPusher 501 a working boat 8m length with a crane to install mooring systems and to work as supply for the NovHarvest 501.


NovaPlatform 501 a working platform of 12x7m to make the assembly of the PE structure at sea on the field.

We join new EU project BioSea

March 27, 2017

In June 2017 the new EU project BioSea started with a kick-off meeting in Spain. BioSea targets the cultivation and biorefinery of 4 micro- and macro-algae into various value-added products. AtSeaNova will be responsible for the cultivation of selected species using its latest generation of AlgaeTex substrates.

AtSeaNova harvests at Solund (Norway)

March 20, 2017

In May 2017 AtSeaNova harvested the seaweeds that had been seeded in November 2016 at its test farm in Solund (Norway). Among the cultivation substrates were newly developed AlgaeNets, AlgaeSheets, AlgaeGrids, AlgaeRibbons and AlgaeRopes. Besides the traditional horizontal positioning, we also tested vertical substrates. Results, videos and photos of the successful cultivation season are available upon request.
