The main objective of the project is to develop an integrated offshore wind power generation system. The added value resides in the use of a special concrete, as well as the energy accumulator.
Both the infrastructure, a maritime concrete base, and the tank will be designed for manufacture with ultra-high performance concrete (UHPC); these types of platforms are currently constructed from steel, with the consequent durability issues caused by chloride corrosion in marine environments.
Furthermore, wind turbine-infrastructure integration will be a key aspect to ensure the success of the proposed system. In addition, the project proposes an innovative methodology for carrying out the seabed analysis, as a first step towards selecting the location of the proposed system and ensuring its proper functioning.
The activities to be carried out are as follows:
- New methodologies for the seabed survey: approach, development and assessment of the seabed through a combination of the geophysical techniques ERT and GPR .
- Design of marine concrete infrastructure for wind turbine foundations: assessment of the possibility of a floating platform or gravity based foundations; taking into account the integration with the storage tank and its regulation system in the design and calculation of the structure.
- Design and integration of the storage tank in the concrete infrastructure: setting out the bases for the calculation and modelling of the UHPC storage tank, sectional stress and justification of reinforcement needs and the definitions of the sections used.
- Wind turbine-platform integration and operation of the overall system: establishing the bases for the design, taking into account applicable regulations, integration and different structural calculations and efforts.
- Port-Marine analysis: valuation of the multiple options for the installation of the wind turbine-platform ensemble in the port-marine space.
The project is headed up by Rover Maritime, with the participation of other entities from the Valencian Community.
