Power Generation Turbine Repairs On-Site

The worlds ever increasing demand for power in all its forms is growing year after year. Nuclear and Fossil fuelled Steam Turbines, Gas Turbines, Wind Turbines, Tidal Turbines, Hydro Turbines they all have to run efficiently at maximum output to meet that demand. Maintaining these turbines and their associated plant is a big job.

The whole aim is to increase running times between planned outages and minimise potential breakdowns situations and that’s where we can help!

Location:
Gothenburg, Sweden

Mission:
Wind Turbines, Worldwide

Challenge:
To remove the weight of a medium-sized car from a solid material by turning on lathe, while maintaining high quality standards.

Solution:
Metalock has developed special machines to handle rings that weigh up to 4 tonnes and measure 2.5 metres in diameter, which are capable of turning at a cutting depth of 8mm.

Each ring is checked with ultrasound to ensure that the rings are completely free of defects.

Result:
3,000 rings per year makes it possible to build 1,500 wind turbines, which gives the world cleaner energy without emissions.
