Wind Energy – T&I
Jan de Nul launched its Offshore Installation Vessel Les Alizés at the CMHI Haimen shipyard in China.

This vessel will be the largest Heavy Lift Vessel in Jan de Nul’s fleet, able to install XXL offshore wind components, in floating conditions and with ultra-low emissions.
The launch started on 2nd January by flooding the dry dock in which Les Alizés was built. Once afloat, Les Alizés was moored alongside the adjacent quay wall. Yesterday, the official launching ceremony took place at the CMHI Haimen shipyard, in the presence of the shipyard management and Jan De Nul Group representatives.
The final phase of the vessel’s construction can now begin, including sea trials. Les Alizés is due for delivery in H2 2022 in good time for her first assignment in Germany for the construction of Gode Wind 3 and Borkum Riffgrund 3 Offshore Wind Farms, transporting and installing 107 monopile foundations for the offshore wind major Ørsted.
Philippe Hutse, Director Offshore Division at Jan de Nul Group: “The construction of our offshore floating installation vessel Les Alizés is well on track. We can look forward to delivery later this year, so that we can continue to build the future of offshore renewable energy. Together with our Offshore Jack-Up Installation Vessel Voltaire, which is also under construction in China, we will have the perfect set of offshore installation vessels that will be able to install current and future generations of offshore wind farms. This is how we offer our customers the most efficient installation solutions and results.”
