Introducing Tension Buoy
Designed to cope with large water-level variations, Tension Buoy removes one of the main barriers for deployment, providing safe, reliable, and efficient anchor mooring systems. By integrating a smart, automatic winch, the buoy continuously adjusts the mooring line length in response to changing water levels.
A Design Rooted in Simplicity and Reliability
At the core of Fred. Olsen 1848’s Tension Buoy is a smartly integrated winch perched atop the structure, designed to deliver dynamic tension control with elegant efficiency. As water levels change, this winch automatically adjusts the mooring chain length, consistently maintaining the optimal tension in the mooring line. Whether deployed temporarily for precise tensioning during installation, or installed permanently to adapt continuously throughout FPV operations, it’s a solution built to meet the real-world needs of changing water levels.
The mooring chain is thoughtfully routed through the buoy’s center: rising from below, gliding over the gypsy, and then descending again, while any surplus chain hangs freely, ready to adapt to shifting sea states. This buoy exemplifies the company’s philosophy of intelligent simplicity: high reliability without unnecessary complexity, and cost-efficient design without compromise.
Unlocking New Potential Across Hydro Dams and Reservoirs
Hydro dams are dynamic, with levels rising and falling by many meters in short periods of time. Where fixed mooring systems struggle with lines being either too short or too long when water level changes, the company’s Tension Buoy adapts the lines to ideal lengths and tension without manual handling. This keeps floating solar arrays stable and secure through every cycle. By making hybridization straightforward, it enables operators to unlock new renewable potential and deliver reliable clean energy.
A Step Towards Sustainable Innovation
Fred. Olsen 1848’s Tension Buoy represents a bold step forward in unlocking the latent potential of reservoirs behind hydropower dams. Its self-adjusting anchoring system ensures floating solar and hybrid installations remain secure in all conditions. In doing so, it transforms challenging water bodies into productive assets, bringing clean energy to surfaces once considered impractical.
When paired with existing hydro infrastructure, the Tension Buoy becomes a bridge to hybrid energy systems that offer greater stability and flexibility. Solar power can supplement hydropower during bright hours or dry periods, while dams continue supplying baseload where needed. Together, they forge a more resilient, efficient energy ecosystem, one that revitalizes existing assets and supports the global shift towards sustainable power.
