Green Energy, Green Piles: Spun Foundations for Offshore Wind Turbines

Green Energy, Green Piles: Spun Foundations for Offshore Wind Turbines

In Kuala Terengganu, a new 20 kW offshore wind turbine is taking shape and it’s showing how spun piles are used in more than just buildings. This project is led by a Public University and piling started back in July 2024.

Why ICP Piles Were Selected

Steel pipes are more expensive and need frequent maintenance on sacrificial anode in order to prevent corrosion, which raises long-term costs. Bored pile on sea requires construction of cofferdam, which is very time consuming and poses a challenge in rough sea. This process takes longer and increases overall expenses.

In contrast, ICP spun piles  give a right balance in providing required bending capacity versus cost. It offers lower installation cost, quicker construction, and excellent durability. Made from high-strength prestressed concrete, they resist corrosion and need very little maintenance, making them a reliable and cost-effective choice.

Application and Green Advantage

ICP supplied 800 mm diameter spun piles for the foundation, installed using a 15 ton hammer from a marine barge. These piles were picked because they are strong and perform well in seawater. The more important part is the Green Pile. It’s a hollow spun pile that uses less concrete, which means less material and a lower carbon footprint. The spinning process makes the pile very dense and high durability even though it consumes less raw materials — a great match for a renewable energy project.

Class C Marine Piles – The Perfect Fit

The project went with Class C marine piles because they are made for offshore use. They handle seawater well and cater for both axial and lateral load, which makes them ideal for projects out at sea. ICP’s Class C piles can take heavy loads and stay stable even over time. For a wind turbine sitting in the ocean, this kind of pile just makes sense, so it was the most practical choice.

Building Stronger, Greener Outcomes

The results have been good: solid foundation, smoother installation, and a smaller environmental footprint. Compared to other foundation systems, ICP’s Green Pile saved time, cost, materials, and created less waste. This project is a reminder that piling isn’t just for towers or bridges – it’s also helping build the foundations of clean energy. We are glad to be part of a future where piles support wind turbines and other green structures.
