This wind farm, which became operational in 2018, has 30 wind turbines with a rated capacity of 3MW, with which it is capable of producing more than 277,000 MWh of clean energy per year.
Sarens has worked on behalf of GE Renewable Energy in the renovation and maintenance of the wind farm, providing its expertise and advanced machinery for the replacement of the blades and repair of the wind turbines.
Theparak wind farm, in the province of Nakhon Ratchasima, has established itself as one of the main energy references for Thailand since its inauguration in 2018, thanks to its contribution of renewable electricity to more than 30,000 homes in the region and thus contributing to the reduction of 120,000 tons of CO2 in the country. To maintain this production, various maintenance tasks, both preventive and corrective, are currently being carried out on the 30 wind turbines of which it is composed.
Sarens, world leader in heavy lifting, engineered transport and crane rental services, has worked on these tasks on behalf of GE Renewable Energy - the concession holder for the maintenance and repair tasks during the first 15 years of the wind farm's operation-. The Sarens engineering team carried out an important preliminary study to analyse the terrain where the work to renovate the blades of one of the turbines would be carried out to ensure the safety of the operation and that the necessary conditions were met for the work of one of its cranes.
Sarens brought a Sany SCC8000A-800T crane unit to Huaypong because of its high load capacity and ease of movement in all types of environments. Its flexibility and advanced hydraulics proved to be key to the precise handling of the wind turbine components to be lifted. The Sarens team was responsible for replacing the NK-38 turbine blades at a height of 157 metres, each weighing 17.5 tons and measuring 67.2 metres in length.
To carry out these tasks with the utmost safety measures, the Sarens team set aside 2,962 m2, in an area with very limited working space. The load had to be lifted to a radius of 26 m and 36 m, and then placed on the ground. To do this, the crane had to slew the load 90 degrees before positioning it onto the blade support.
Theparak wind farm, located in Huaypong, is the most important wind farm in the province of Nakhon Ratchasima, with a higher production than other wind farms such as Lam Takhong (with a capacity of 24 MW). It is also one of the most important in Thailand, although behind parks such as Khao Yai Thiang (100MW), which is why it is considered strategic to achieve the country's objectives of achieving 20% renewable energy in its grid by 2030, according to the country's Power Development Plan (PDP).
Sarens has extensive experience in the lifting, transportation and installation of turbines for windfarms around the world. Also in Belgium, Sarens installed six new wind turbines at the Siemens Gamesa facilities located in the municipalities of Gesves and Ohey. In Belarus, in sub-zero temperatures, Sarens installed the tallest Vestas wind turbines in Asmolovichi. At the Glenn Innes wind farm in New South Wales, Sarens installed the tallest wind turbine towers in Australia.
