Sarens has successfully completed critical maintenance operations at the Theparak Wind Farm in Huaypong, located in Thailand’s Nakhon Ratchasima province. Acting on behalf of GE Renewable Energy, Sarens was responsible for the safe and efficient replacement of turbine blades and structural repairs on site.

The Theparak Wind Farm, operational since 2018, is one of the most important wind energy assets in the country. With 30 turbines generating a combined capacity of 90 MW, it produces over 277 000 MWh of clean energy annually—enough to supply power to more than 30 000 households. Its contribution helps reduce CO₂ emissions by approximately 120.000 tonnes per year and supports Thailand’s goal of achieving 20 percent renewable energy in the national grid by 2030, as set out in the Power Development Plan (PDP).

Sarens was tasked with the replacement of blades on the NK-38 turbine, requiring precision engineering and careful site preparation. Each blade measured 67,2 metres in length and weighed 17,5 tonnes. Prior to the lifting operation, Sarens engineers conducted a detailed site study to assess the terrain and ensure the ground met all safety requirements.

To execute the lifts, Sarens deployed its powerful Sany SCC8000A crawler crane, selected for its 800-tonne capacity and optimal performance in confined and challenging environments. The crane’s advanced hydraulics and flexibility were instrumental in safely handling the oversized turbine components at a height of 157 metres.

Working within a limited 2.962 m² area, the team faced additional complexity due to restricted space and lifting radii of up to 36 metres. The load had to be slewed 90 degrees mid-air before being precisely positioned on the blade support—a manoeuvre that demanded both skill and technical coordination.

With this successful intervention, Sarens continues to support Thailand’s renewable energy infrastructure, reaffirming its position as a global leader in heavy lifting and engineered transport. The Theparak project adds to Sarens’ extensive portfolio of wind energy operations around the world, including installations in Belgium, Belarus, Australia, Germany and many more countries.
