Prototype crane being constructed for 20 MW offshore wind turbines

The Netherlands-based Tetrahedron, together with its consortium members Jack-Up Barge BV, TNO, Shell, and GE, has unveiled plans to construct a 130-metre tall prototype crane for next-generation offshore wind turbines.

This comes after the consortium received a grant from the Dutch Government in the form of a loan and an investment.

By building the prototype, Tetrahedron plans “to measure the crane’s structural behaviour in order to confirm the design and test its resistance against current phenomena such as crane deflection and a sudden loss of load,” the company said.

Additionally, the full-scale prototype will serve as proof to the wind industry that Tetrahedron’s crane has the ability to lift wind turbines higher than those that can be lifted by standard cranes without the need to build a completely new jack-up vessel, according to the Dutch firm.
