Monopile cost reduction and demonstration by joint
applied research
Primary goal:
The primary project goal is to enable more cost effective offshore wind systems. The mean to reach the goal is by reducing the costs of production, installation and maintenance of monopile foundations.
Short description:
The vast majority of all offshore wind turbines are installed on monopiles. Yet there is little integration between, respectively, the design of the wind turbine and the design of the monopile. This lead to non-optimal conservative designs and consequently too expensive wind systems.
Three value drivers are identified and targeted to achieve the primary goal of cost reduction:
- Production cost reduction is achieved by adopting a design strategy that takes the entire wind system into account (design integration) and by improved design basis of welded joints.
- Installation cost reduction is achieved by thorough rework of outdated and conservative pile-soil interacting models.
- Maintenance cost reduction is achieved by wave load management by design of new appurtenances, respectively.
