Expanding our presence in that market with this VRA aligns with our global business strategy. With our first state-of-the-art newbuild received, and six additional newbuilds being delivered over the coming years, we will be able to handle the largest and most complex next-generation offshore wind installation projects, further building our backlog and ensuring that our customers and partners can look to Cadeler as offering the strongest choice of flexibility and supply-chain certainty”.
