North Kyle Wind Farm is a 49-turbine site situated on a former open cast mine in East Ayrshire, Scotland. During the ground investigation works preparing for the project, ground gas was discovered. Roxtec cable seals were installed within the turbine foundations to protect future site users from potentially harmful ground gases.
The North Kyle Wind Farm project is being completed by civil engineering company Jones Bros on behalf of multi-technology, renewable energy business, Brockwell Energy Ltd. The wind farm will produce over 200MW of clean renewable energy and power around 160,000 homes per year.
Recommended by designer
“Due to the ground gas being discovered, we required a cable sealing solution to prevent potential gases,” says Sub Agent Paul McLaughlin of Jones Bros. “We chose Roxtec seals because Roxtec was recommended to Jones Bros by our designer, Tony Gee.”
Jones Bros has a forward-thinking approach, and their engineers often develop innovative solutions for energy, renewables and coastal infrastructure for demanding environments and ecologically sensitive areas.
Protecting life and assets
In this case, ducts in the turbine foundations on the old mine had to be protected from gas. There was a risk that the basement of the turbine would be filled with gas once the turbines were erected. This was a serious risk to operatives building, servicing and maintaining the wind turbines.
“Finding the right sealing solution meant there would be no immediate risk to operatives in the turbine when we were in the construction or operational phase,” says Paul McLaughlin.
Roxtec seals are easily adaptable and could therefore be used for cables from 185mm2 to 630mm2.
Prepared for future needs
Not all ducting in the turbine base foundation was going to have a cable installed. Some ducting was installed as spare capacity in case it would be required in the future.
“Due to this the knock-out sleeves from Roxtec were brilliant to use as this meant we were not required to install a seal and therefore kept the cost down,” says Paul McLaughlin.
Roxtec knock-out sleeves for seals and conduits ensure tightness prior to cable routing. They provide spare capacity for future expansion thanks to the pre-sealing knock-out plate feature.
We chose Roxtec gastight cable seals.
Why use Roxtec?
- Certified protection
- Adaptability to cables of different sizes
- Knock-out sleeves for pre-sealing of site
