Sarens has successfully completed the replacement of a wind turbine blade at the Theparak Wind Farm in Thailand, supporting the continued operation of a facility that offsets approximately 150.000 tonnes of CO₂ per year.

Commissioned by GE Renewable Energy Thailand, the operation took place at the Theparak Wind Farm in Nakhon Ratchasima, a key renewable energy asset that has been contributing to Thailand’s clean energy transition since its commissioning in 2018. The wind farm supplies electricity to more than 30.000 households and plays an important role in the country’s objective of achieving Net Zero by 2050. Prior to execution, Sarens conducted a detailed site study to determine the optimal lifting solution, assessing crane access, ground bearing capacity, and lifting sequences to ensure maximum safety and efficiency. Based on this analysis, Sarens selected its SCC8000A crawler crane, configured with a main boom and wind jib, offering a lifting capacity of 800 tonnes—well suited for operations on turbines exceeding 150 metres in height.

Sarens’ scope of work involved the replacement of a blade measuring 67,2 metres in length and weighing 17,5 tonnes, installed on a tower with a hub height of 157 metres. The operation included the removal of the damaged blade, slewing and lowering it to the ground, followed by the lifting and installation of the new blade. The total lifted load during the operation amounted to 41,5 tonnes.

The project presented several challenges, including limited working space, restricted access routes, and strong wind conditions typical of the region. These factors required meticulous planning, strict traffic control, and precise crane positioning. Lifting operations were carried out exclusively within permitted wind limits, with continuous monitoring to ensure full control and safety throughout the lift.

The SCC8000A was transported from the Sarens yard to site in five days, requiring 44 transport movements, followed by a five-day assembly period. Despite the confined site layout, assembly and commissioning were completed within the planned schedule.

Located in Huaybong, Theparak is the most significant wind farm in Nakhon Ratchasima province and a strategic asset within Thailand’s renewable energy mix, contributing to the national target of reaching 20% renewable energy generation by 2030, as outlined in the country’s Power Development Plan.

This project further reinforces Sarens’ extensive experience in wind energy worldwide, having supported wind farm developments across Europe, Asia, Australia, and beyond through the installation, maintenance, and replacement of turbine components in complex and demanding environments.
