Abstract

This presentation outlines enabling and advancing maritime Multi-Use Installation (MUI) technologies to enhance offshore wind farm development.
Firstly, the risks and opportunities of MUI scenarios have been introduced. The selected scenarios consist of: i) high commercial potential cross-sectoral projects recommended by EU-funded consortia, and ii) six commercial projects from the offshore project developers' portfolio (both EU and non-EU).
Secondly, the joint technology development for MUI commercial applications is comprised of both integrated automation and remote monitoring systems and synergies for sharing logistics and infrastructure. To reduce the risks for operators, the technology verification includes both MUI operational compatibility tests in Laboratory conditions and integrated MUI system and module operability tests at real operational sites. To increase the investors' confidence, the project implementation aims at unlocking MUI market potential by overcoming both technological and non-technological barriers.
Thirdly, the impacts on the offshore wind farm development by MUI will be addressed. The study cases show the great potential of MUI commercial applications with regards to economic feasibility and environmental sustainability. The cases of adding MUI to existing offshore wind farms and the joint development of new wind farm with MUI confirm that the MUI approach turns any potential conflicts into maximizing joint benefits. Furthermore, the cases of reliable, flexible, green and cost effective electrical power for offshore users (e.g. oil/gas installation, aquaculture farm, vessels, desalination, tourist industry and ocean cleaning) will improve offshore wind farm economics whilst also effectively promoting Blue Growth and minimizing the potential impacts to the marine environment.

Method

This study capitalizes on both the scenarios by EU-funded consortia and the commercial projects from the offshore project developers' portfolio. The joint technology development for MUI commercial applications focuses on both the integration and enabling technologies. The MUI development has been integrated with wind farm developers' asset management, including both optimizing operation and maintenance, creating both new business opportunities and life time extension of the wind farm infrastructure.

To reduce risks for operators, the technology verification program goes one-step further than the design and modelling. This includes both MUI operational compatibility tests in Laboratory conditions and MUI system and module adoption at real operational sites. To increase investors' confidence, the deployment plans combine the required non-technological and technological actions to bring MUI towards commercial application.

 

Results

This study results in a set of MUI case studies which increases the offshore wind farms asset value. Firstly, adding MUI to an existing offshore wind farm generates cost-effective cross-sectoral solutions (e.g. bio-fouling removing and utilizing), creates new business opportunities (power charging for vessels and fresh water supply by adding desalination systems) and the life time extension of the wind farm infrastructure through re-using by other sectors.

Secondly, the joint development of two new MUI provides new opportunities to implement difficult offshore wind farm projects by maximizing the joint benefits. The two development plans for offshore wind farms at far offshore and at deep water sites show the economic improvements through the increased yield from the aquaculture production and MUI synergies during the life cycle.

 

Conclusions

This study firstly proposed MUI technology development to reduce risks for both MUI operators and investors.
Secondly, a set of MUI cases for adding MUI to an existing offshore wind farm and the joint development of new MUI shows that MUI has the potential to turn the conflicts with other sectors into the joint benefits which accelerates the realization of the EU offshore wind power development target.
Thirdly, the offshore wind farm with MUI has potential to provide reliable, flexible, green and cost effective electrical power for offshore users which promotes Blue Growth while minimizing the marine environmental impacts.
Fourthly, MUI accelerates the movement of aquaculture farming to offshore sites. It increases aquaculture food production to meet both increased consumption and quality requirements.

Objectives

1. Enabling and advancing maritime Multi-Use Installation (MUI) technologies to enhance offshore wind farm development.
2. Adding multi-use to an existing offshore wind farm generating cost-effective cross-sectoral solutions.
3. The joint development of new wind farm together with Multi-use turns the potential conflicts into joint benefits.
4. Co-use of offshore wind space for aquaculture farming accelerates the movement of aquaculture farming to offshore sites.
