Enhancing cable protection systems for offshore wind: Insights from the QUADRE CPS JIP initiative
As the world increasingly shifts towards renewable energy, offshore wind energy emerges as a crucial component. This transition, however, presents unique challenges, particularly with subsea power cables used in offshore wind farms. The QUADRE CPS joint industry project (JIP) aims to refine the qualification and design of these cable protection systems (CPS), crucial for ensuring the integrity and functionality of subsea power cables.
The challenge with current CPS designs
The offshore wind industry faces significant challenges with the existing CPS designs applied at wind farm foundations. These challenges include inadequate protection and failure to account for hydrodynamic loads near foundation structures, which are often underestimated in current design practices. These issues can lead to premature cable failure, posing substantial risks and costs to wind farm operations.
Objectives and scope of the QUADRE CPS JIP
The main goal of the QUADRE CPS JIP is to develop and standardize a robust design philosophy for CPS used in offshore wind applications. This involves a comprehensive review of current design codes and the development of new guidelines that address the unique conditions of offshore wind farms. The project will focus on understanding failure modes, refining design methodologies, and incorporating hydrodynamic loading considerations into CPS designs.
Why is the focus on CPS crucial?
CPS plays a pivotal role in safeguarding subsea cables from physical damage and environmental wear, which are critical to the reliable operation of offshore wind farms. By improving CPS designs, the industry can achieve better durability and reliability of these systems, ultimately reducing downtime and maintenance costs.
Collaborative efforts and expertise
Led by DNV and in collaboration with Deltares, the QUADRE CPS JIP leverages expert knowledge and past experiences in CPS failures to enhance design standards. The initiative is a response to the urgent need for clearer, more comprehensive guidelines that reflect the specific requirements of offshore wind setups.
Invitation to join QUADRE CPS JIP
Industry stakeholders, including CPS suppliers, cable manufacturers, wind farm developers, and operators, are invited to participate in this initiative. By joining the QUADRE CPS JIP, participants will have the opportunity to directly influence CPS design standards, gain early insights into CPS performance, and network with industry experts.
For further involvement
The project is set to run over a year, with multiple workshops and feedback sessions scheduled to maximize participant engagement and input. For more information or to express interest in the QUADRE CPS JIP, stakeholders are encouraged to reach out and participate in the upcoming webinars and sessions planned for 2024-2025.
This initiative not only aims to address the immediate technical challenges but also contributes to the long-term sustainability and efficiency of offshore wind energy, marking a significant step towards a more renewable energy-dependent world.
