DNV GL Develops Digital Turbine Monitoring Tool

DNV GL has launched WindGEMINI, its first online digital twin tool said to enable better informed wind operation decisions by giving wind farm owners and operators insights into turbine condition and performance.

The WindGEMINI, as DNV GL said, is built on the company’s 25 years of wind turbine design experience and on the analysis of more than 50GW of global offshore and onshore wind farms.

The framework gives owners and operators 24/7 access to key metrics and advanced analysis to understand the performance, condition and remaining life of a turbine and its components, which can be used to optimise servicing, inspections and plan repairs or replacements, thus minimising downtime and lost revenue, as well as informing financial modelling and strategic decision-making processes, DNV GL said.

According to the company, the WindGEMINI is based on digital twin technology, equipping users with digital copies of their wind turbines which are continuously updated in real-time, making use of the stream of information received from turbines and wind farm sensors, to reflect the real conditions the turbines experience on site.

In addition, DNV GL said that the tool is compatible with any turbine model and can be utilised across the entire portfolio.

Prajeev Rasiah, Executive Vice President for DNV GL’s energy business in Northern Europe, Middle East & Africa, said: “As the wind industry matures, there is constant pressure to reduce costs and increase revenue, and grid operators no longer tolerate downtime and under performance. WindGEMINI is part of DNV GL’s drive towards a more digital future and, as a leading independent advisor to the renewables industry, builds on our expertise of leveraging technology to drive down cost of energy.”
