Minesto Advances Technology for Hestfjord Dragon Farm
With great anticipation, Minesto has recently achieved a significant milestone in the development of its Hestfjord Dragon Farm. Following the successful commissioning and extensive grid-connected operation of its Dragon 12 technology, the company has directed its focus towards evaluating the overall performance of its power plants.
Performance Assessment and Technical Specifications
Over the past months, Minesto has performed a comprehensive analysis including performance evaluations and critical systems checks. An independent third-party technology review by DNV has greatly contributed to this process. Alongside this work, the company has also progressed in site development, confirming optimal tidal conditions for the intended operations.
The design and technical specifications for the upgraded Dragon 12 system align closely with the initial plans for the first Dragon farm in Hestfjord, with a targeted output of Phase 1 at 10MW.
Key Enhancements to the Dragon 12 System
As part of the upgrade initiative, several promising enhancements have been confirmed to optimize the Dragon 12 systems specifically for the Hestfjord site:
- The tidal resource assessment has been continuously refined, allowing for a tailored design of the Dragon 12 power plants.
- While most hardware configurations will remain consistent, there will be a notable increase in generator capacity, which will enhance overall efficiency.
- The modification of the wing profile and an extended tether have been planned to further boost production yields.
- A robust service and maintenance strategy has been established to minimize operating costs both on-shore and off-shore.
- Minesto has confirmed the use of existing, proven technologies for subsea cables, which simplifies their electrical infrastructure.
- The foundation technology utilized in Vestmanna has been validated and will be similarly applied in Hestfjord.
Dr. Martin Edlund, CEO of Minesto, declared, "Our recent efforts have led to two key conclusions: first, we can already provide the lowest cost of ocean energy with our first array, and second, we’ve identified an ideal tidal site for our advancements. Although launching a small-scale project comes with some energy cost disadvantages, we are well-positioned to reduce LCOE, where many marine energy technologies are seeking to end their journeys."
Ongoing Development and Testing Initiatives
Minesto continues to enhance its operations in Vestmanna, particularly focusing on developing commercial offerings tied to Hestfjord. A recent two-week campaign with the Dragon 12 has led to improved procedures for launching and recovering the kites. This enhancement is crucial for managing larger operational campaigns effectively.
Additionally, the company is making preparations for the deployment of new small-scale systems, which will cater to microgrid customers across multiple sites. This strategy includes the D4 systems at various sites and improving seabed infrastructure for a more effective Dragon system.
Longer Tether and Critical Subsystems Focus
As operations move forward, the water depth at the Vestmanna location permits a 15% extension of the tether, which is currently under production. Alongside this development, Minesto is committed to verifying the reliability of critical subsystems and operational procedures.
The production performance during the Spring campaign reinforces the importance of these improvements as Minesto gears up for commercial scale operations in Hestfjord. As the company transitions from R&D activities to expansive commercial operations, it understands the need for enhanced operational methodologies, training, and documentation.
As Dr. Edlund aptly summarized, "Our technical and commercial development focuses on the next significant step—the array build-out." This optimistic viewpoint showcases Minesto's dedication to leading within the marine energy sector.
