Offshore wind farms with fixed bottom at 90 meters depth? Offshoretronic says yes
Barcelona-based Offshoretronic SL and its new Asian partner unveiled a new fixed-bottom foundation design that would be fully scalable and scalable for wind turbines with a capacity of over 20 MW installed in water depths of up to 90 meters away.
The newly developed TRIPOD “PLUS ©” foundation would be adaptable to all different types of marine soils and would have no size limitations or restrictions for manufacturing and logistics on land.
The new foundation consists of two parts: a tripod and a monopile insert which, according to Offshoretronic, are easy to set up and transport in two separate parts.
The foundation can be attached to the seabed with pre-stack, post-stack, suction buckets or a new combination of a small-sized suction bucket and post piles, which would allow for quick installation and the use of larger wind turbines in deeper water.
The monopile insert has a fixed-bottom suction cup to transfer and distribute the loads of larger wind turbines and requires a single lift during installation without the need to install an additional transition piece, Offshoretronic said. .
The foundations also feature connection rings with integrated fiber optic force sensors for real-time monitoring of lateral forces.
The company said its durable installation crane vessel will be able to transport and install four 20 MW “PLUS ©” fixed-bottom TRIPODS in a single trip.
“With our new partner in Asia, we will be able to facilitate FAST and profitable global project executions and meet the expected ceiling in the XXL foundation supply chain by 2025. The new TRIPOD“ PLUS © ”foundation has several new innovations based on combinations of proven concepts eliminating any risk of installation and / or operation and maintenance ”, said the project director Jeroen berkhout.
