PowerBuoy® Wind Wave and Solar
The PowerBuoy® Wind, Wave and Solar is the ultimate ocean pioneer. Combining wave, wind, and solar energy, it delivers unmatched power and autonomy for the most demanding missions. From supporting complex offshore infrastructure to enabling advanced scientific research, the PowerBuoy® Wind, Wave and Solar is built to lead the way.

Continuous Power, Real-Time Data Transfer
The PowerBuoy® stands out as a continuous power source for on-board payloads or seabed-located equipment. It also excels in providing real-time data transfer and communication to remote shore facilities. Designed to store ample electric energy, the PowerBuoy® ensures reliable “ride through” power even during extended periods of calm seas.
Designed for Operational Efficiency
OPT has meticulously designed the PowerBuoy® to streamline operational costs (OPEX). Its deployment and recovery processes are simplified, compatible with vessels commonly used in offshore marine operations. The PowerBuoy® is engineered for infrequent maintenance, with designed intervals every three years, and features a comprehensive control and management system for proactive maintenance strategies, enhancing both availability and operational effectiveness.
Reliability in the Most Demanding Conditions
Proven in rigorous sea trials, including deployment off the New Jersey coast during Hurricane Irene, the PowerBuoy® technology has demonstrated its resilience and reliability, even in challenging conditions. Originally tested for a US Navy project to power coastal security networks, it has shown exceptional performance and durability.
Ready for Deployment with Minimal On-Site Preparation
The PowerBuoy® is designed with compatibility in mind, anticipating that exterior payloads will be shipped in standard ISO shipping containers. This approach minimizes on-site preparation requirements, making it easy to mount payloads on the buoy prior to deployment.
One Platform, Infinite Possibilities
OPT’s technology presents a paradigm shift in how offshore energy operations are powered and managed. By offering safe, reliable, and persistent power and communication platforms, OPT not only drives down operational and capital costs but also enhances asset utilization and overall production performance. Our solutions provide an economical alternative to traditional, cost-intensive power delivery systems, making even low-yield projects viable.
