?? Today, we share insights from two papers: "Design and Analysis of Shared Anchor Layouts for Floating Wind Farms in Deep Waters," and "Comparison of Coupled and Uncoupled Modeling of Floating Wind Farms with Shared Anchors." The first research explores taut mooring systems and shared anchor layouts in the Humboldt Bay area, utilizing the International Energy Agency (IEA) 15 MW reference turbine. The latter, highlights how modeling methods and assumptions, such as those using OpenFAST and FASTFarm software, can impact shared anchor loading. Both benefit from the exceptional expertise and dedication of Bruce Martin, Principal R&D Engineer at Principle Power. Bruce’s deep understanding of the field and innovative approach have significantly advanced the research, which will be published in upcoming editions of the journals Ocean Engineering and Journal of Marine Science & Engineering. Our collaboration leverages insights from the DeepFarm project, Principle Power’s R&D initiative dedicated to developing optimal mooring designs for deep-water, utility-scale floating offshore wind farms, funded by NYSERDA & National Offshore Wind Research & Development Consortium. Key findings from the research suggest that shared anchor solutions could achieve significant cost savings, even when considering the complexities of installation. These results highlight the potential of shared anchor systems to improve efficiency and significantly reduce costs for floating wind farms, as well as the importance of industry collaborations, such as ours with the University of Massachusetts Amherst and the National Renewable Energy Laboratory to strengthen technology maturity and advance a step further in lowering the levelized cost of energy.

?? Floating wind project development teams are under high pressure from their stakeholders to deliver competitive business cases and deliverable execution plans. These often-competing pressures can incentivize developers to front-load contracting decisions to demonstrate maturity. Decisions about contracting strategy are highly consequential. These set the rules of engagement for the engineering and procurement phase and directly affect the owner’s ability to control the project and shape equity returns. These decisions may even mean the difference between success and failure for the first wave of commercial scale projects. Aaron Smith joined the latest WORLD FORUM OFFSHORE WIND (WFO)’s subcommittee on interface risk management to share Principle Power’s experience working under different contract structures and provide actionable recommendations for the successful implementation of two main contracting strategies applied in the industry today: Engineer then Procure and Platform EPC(I). You can access a set of recommendations for getting contract structures right by logging in to the WFO member area, where the recording is exclusively available to members, or please reach out to us directly for a copy of the slides. We thank the WFO for the opportunity, and Louise Efthimiou for moderating the insightful discussions.

??Floating wind platforms connect to the grid using dynamic power cables that must withstand motions within the water column. These cables are typically laid out in a radial network and gather power from individual units for export to the shore.? Some types of wind turbine major component replacements (MCRs) require towing the platform to shore to replace major components using an onshore crane at port. By disconnecting units from their position, these large corrective operations can interrupt the grid connection for both the affected unit and other units on the same array cable, amplifying related production losses. In a normal scenario, the disconnection and reconnection operations are complex because the dynamic array cable sections, which have ancillary equipment (e.g., buoyancy modules) that cannot be uninstalled, must be cut, sealed, and wet-stored on the seabed. A section of the cable may need to be cut following retrieval to assure the integrity of the cable against water ingress.? To address these challenges, Principle Power developed the patented I-tube, a plug-n-play connector solution that simplifies cable connection, disconnection and deployment, and re-connection. In the event of a MCR, jumper cables are disconnected from the wind turbine and the interarray cables joined within the I-Tube housing using a T-connector.? The system is then sealed and deployed into the water where the I-tube acts as a spar buoy, floating on the surface and maintaining electrical connection between the wind turbines. There is no need to adjust ancillary equipment or cut cables.? The I-Tube deployment and recovery process leverages our WindFloat? smart Hull Trim System (HTS), which uses the ballast system to tilt the platform for seamless and simple deployment and recovery of the I-tube. The approach dramatically reduces the operational complexity, costs, and risks associated with tow-to-shore MCRs operations. The I-tube has been installed at the WindFloat Atlantic Project and is currently being deployed at the LES EOLIENNES FLOTTANTES DU GOLFE DU LION project, which is set for installation later this year.

?? Mitigating environmental impact such as Greenhouse Gas Emissions (GHG) involves the entire supply chain, and some governments now include auction criteria requiring commitments to reduce overall project emissions and maximize end-of-life component recycling. Materials and fabrication are the main sources of project emissions for floating wind projects, but the high recyclability of assets helps to mitigate overall impact at the project end-of-life stage. Principle Power has developed a framework to calculate GHG emissions for current and future projects drawing on 105 MW of project experience. We use this GHG emissions tool during the preFEED and FEED studies to help our customers?assess baseline impacts for their specific project and explore levers available to?reduce lifecycle emissions. At the latest WFO ECB – Floating Offshore Wind Committee meeting, David Silva presented an overview of WindFloat?’s emissions breakdown by material before and after its end-of-life stage Based on a case study of representative 500 MW commercial project in South Korea. We thank the WORLD FORUM OFFSHORE WIND (WFO) for the opportunity and invitation to present our framework, and Agni Argyri for moderating the insightful discussions.

?? “The world urgently needs innovative solutions for large-scale clean energy generation. In 2009, as a young Naval Architect fresh out of University of California, Berkeley, I took a leap into uncharted waters by joining Principle Power to pioneer floating offshore wind technology. I was eager to be part of the solution. ? Our small, tight-knit team wore many hats and shared an unshakable belief in the potential of floating wind. Every challenge was a first-of-its-kind, and every moment felt like history in the making. ? I’ll never forget the night we were loading out our WindFloat 1 prototype - the world’s first full-scale floating wind turbine on a semi-submersible platform. I was unexpectedly appointed “ballasting engineer” and worked through the night, filling ballast compartments and sleeping in the turbine tower with just a sleeping bag to meet the schedule. Despite the exhaustion, we pushed forward, knowing the significance of what we were building. ? Fast forward to 2025, Principle Power has become a global leader in floating wind technology, demonstrating the feasibility, bankability, and scalability of our solutions through multiple small commercial projects. Now, we’re focused on deploying the first large-scale utility floating wind projects. ? Over the past two decades, I've been fortunate to work on projects that stretch boundaries. But what truly inspires me is the dedication of our engineers at Principle Power. Thanks to their creativity and determination, floating wind has transitioned from a futuristic concept to a practical reality with the potential to transform the global energy landscape.
