Siemens Gamesa has awarded Cadeler a $90m (€76m) contract to transport and install its SG 14-22 DD turbines.
The contract also contains another $30m in options.
The 14MW turbines will be among the largest in the world and have a 25-year lifetime.
Cadeler’s vessels will be able to install the wind turbines standing 252 metres in height from sea level to the tip on the rotor blade, which measure 108 metres in length.
Chief excutive of the Oslo-listed supplier Mikkel Gleerup said: “We are extremely please that Siemens Gamesa has chosen us to help them release another of their projects in the world of renewable energy.
“At the same time, Cadeler achieves yet another important milestone, delivering on our commitments from our listing last year.
“This is naturally also very reassuring to me and the entire team at Cadeler.”
