Netherlands-based Tetrahedron and its alliance members jackup Bar GE BV, TNO, Shell and GE have unveiled plans to build a 130-metre-high prototype crane for next-generation offshore wind turbines.
Tetrahedron said that by building the prototype crane, the company plans to measure the crane's structural performance to confirm the design and test its ability to cope with current problems such as crane deflection and sudden loss of load.
In addition, according to the Dutch company, the full-scale prototype will prove to the wind power industry that Tetrahedron’s cranes are capable of installing higher wind turbines than current standard cranes, and can be installed on the original installation vessel to achieve upgrades and upgrades. There is no need to build a new self-elevating wind power installation vessel.
The prototype is scheduled to be completed in the Netherlands in 2024.
Tetrahedron has developed a patented new crane. Compared with traditional lifting cranes, the new crane has a stronger lifting capacity on the same basis. It also stated that the crane can make existing jack-up ships suitable for installing next-generation offshore wind turbines at sea, and its design is suitable for units up to 20 MW.
