Saitec Offshore Technologies has installed a series of Nature Inclusive Design (NID) systems at its DemoSATH floating wind platform off Spain as part of the Aquasath project. Through DemoSATH Lab, the operating demonstrator is being used as a full-scale test site to study environmental interactions, improve monitoring methods and evaluate ways to support marine biodiversity alongside floating offshore wind.
The installation includes NID elements attached to DemoSATH's underwater columns and filled with shells and mussels to create new surfaces and microhabitats. The structures are intended to provide feeding, shelter and growth areas for marine species around the floating foundation.
The project also includes a multi-trophic aquaculture pilot integrated with the platform. Using a mother rope fitted with lantern nets, mussel ropes and collector ropes, the trial will assess the feasibility of cultivating European flat oysters (Ostrea edulis), pullet carpet shell clams (Venerupis corrugata), mussels and Ulva algae alongside floating offshore wind infrastructure.
During the first stage of the project, live material was collected and the NID elements were temporarily installed on a mussel raft before being transferred to DemoSATH. Each element was assigned a unique identification number and colour code to ensure traceability throughout the installation process.
In the second stage, the elements were transported offshore and installed on the floating platform. Mar Ceibe supplied the live material, while Instituto Kardala provided the mussel raft and technical support. Kotazero carried out the underwater installation, and Amarradores de Santander provided the installation vessel, mooring services and operational support.
