Envision Energy Unveils the EN-252/16.7 Offshore Wind Turbine

Envision Energy, a reputable leader in green technology, has introduced its latest offshore wind turbine, the EN-252/16.7, designed specifically for high-wind environments. This innovative turbine aims to set new standards in energy production and operational reliability, catering to the increasingly demanding requirements of global offshore wind markets.

Key Features and Performance

The EN-252/16.7 turbine boasts a nominal power of 16.7 MW, featuring a high-performance rotor tailored for optimized efficiency. Its propulsion system is integrated effectively, allowing for increased energy output while promising significant reliability and superior project returns. Envision's commitment to precision engineering and technological advancement underpins the design of this turbine, ensuring it can harness the power of high-intensity marine wind resources.

Drawing from the proven Model Z platform, which has been operational since 2023, the EN-252/16.7 reflects over ten years of experience and continuous improvement in the offshore wind sector. The development of this new model included rigorous validation processes at both the component and system levels, assuring prospective buyers of its robustness and efficiency in real-world conditions.

Enhanced Energy Production

Envision’s latest turbine is engineered for enhanced energy generation, achieving approximately 2.99 square meters per kilowatt in its sweeping area to capacity ratio. In large-scale offshore wind farms, this turbine is estimated to provide an annual energy output increase of 1% to 2%, alongside a reduction in the turbine count by nearly 10%. This reduction plays a significant role in decreasing the levelized cost of energy (LCOE) by approximately 2% to 4%, depending on site-specific conditions and project configurations.

The inherent adaptability of the EN-252/16.7 allows for potential boosts in turbine power for specific locales, further driving down required capital expenditures (CAPEX) and enhancing energy yield.

Proven Reliability

The reliability of the EN-252/16.7 is fortified through comprehensive validation protocols established by Envision. Testing has included extensive load trials on the transmission system and over 600 hours of accelerated life testing, ensuring that both the components and system interactions can withstand demanding operational environments.

Their unique vertical integration approach has proven beneficial, with extensive experience accrued from approximately 12,000 gearboxes, 12,000 main bearing sets, 25,000 blade sets, 23,000 generators, and 28,000 converters. By controlling critical components of the turbine's design and manufacturing, Envision ensures consistent quality and reliability.

Safety and Resilience in Extreme Conditions

Designed to endure extreme marine conditions, the EN-252/16.7 can withstand sustained wind speeds of up to 58.5 m/s, with gusts reaching as high as 82 m/s over a brief three-second burst, reflecting a design lifecycle durability of fifty years. Enhancements in safety are incorporated through the ability to integrate energy storage systems, enabling backup power during outages from external grids, particularly during critical phases like pre-commissioning or severe weather incidents.

The turbine's integrated network-forming control capabilities and black start functions exhibit its adeptness in maintaining stable operation even in variable grid conditions, further emphasizing its resilience in tempestuous weather scenarios.

Lifecycle Optimization through AI

To enhance operational reliability, the EN-252/16.7 is equipped with Envision's Galileo AI system, which promotes early fault detection and proactivity in maintenance practices throughout its lifecycle. This robust monitoring framework serves over 20,000 turbines since its commercial launch in 2020 and utilizes advanced algorithms to monitor key components, providing predictive alerts that can anticipate potential failures one to six months in advance, thus minimizing unplanned downtime and operational costs (OPEX).

In conclusion, Envision Energy's EN-252/16.7 turbine represents a significant leap forward in offshore wind technology, prioritizing efficiency and economic viability while responding adeptly to the challenges posed by maritime environments. The turbine not only promises increased energy production and reliability but also assures a commendable return on investment for its users in the long term.
