Periodic Reporting for period 2 - i4Offshore (Integrated Implementation of Industrial Innovations for Offshore Wind Cost Reduction)
Periodo di rendicontazione: 2020-05-01 al 2021-04-30
The project was also intending to become more than just a technology demonstration as the project would also have combined the technological advances with deep and targeted study of holistic concepts for leaner manufacturing, onshore and offshore transport of components for full scale operation and innovative strategies for operation and maintenance as well as for offshore logistics and installation.
The project intended to provide special attention to the mitigation of bottlenecks in the value chain as reduction of cost is the paramount concern across all stages of the offshore wind manufacturing, construction, installation, operation, maintenance and decommissioning process.
Enabled by the innovative concepts for manufacturing, logistics, installation, and O&M, actual data from the installed and operated wind turbine system would have validated the commercial viability of implementing a GW-sized offshore wind farm based on the i4Offshore field-proven solution.
The new offshore solution would have provided new, modularized components allowing leaner, faster, more reliable and more cost-efficient logistics-solutions in the transportation, handling, installation and O&M phases of future commercial project development.
The i4Offshore project would have delivered innovative, reliable and robust offshore wind power solutions reducing the LCoE for the entire wind farm to 80 €/MWh (or lower) before 2025.
During the 18 months period the project was running, we managed to accomplish the following work:
• Preliminary structural design of the steel jacket
• Preliminary design of the concrete TP
• Geotechnical design of the suction bucket
• Integrated load analyses (two load iterations)
• Development work on the foundation load-reducing features: Concentrated Winding Topology and Trimstall Technology
• Further refining of a modularized jacket assembly process
• Design of a new unarmoured 66 kV 3-Core Aluminium cable with a separate Fiber Optic pipe.
• Developing of a cable hang-off system for the 3-Core cable
The project was presented to several Danish political stakeholders. More than 20 dissemination activities took place including conference and event participation, press-releases and publications, with scientific policy makers and industrial audience reached.
Furthermore, a project website, press-releases and infographics have been made.
We are convinced that the completion of the detailed engineering and fabrication phase would have proven the project a success in its ambition to deliver innovative, reliable and robust offshore wind power solutions reducing the LCoE for the entire wind farm to 80€/MWh - or even lower.
