Belgium/China – Jan De Nul’s Offshore Installation Vessel Les Alizés has been launched at the CMHI Haimen shipyard in China.
This vessel will be Jan De Nul’s largest Heavy Lift Vessel, capable of installing XXL offshore wind components in floating conditions with ultra-low emissions.
The final phase of the vessel’s construction, including sea trials, can now begin. Les Alizés is scheduled for delivery in H2 2022, just in time for its first assignment in Germany, transporting and installing 107 monopile foundations for Orsted’s Gode Wind 3 and Borkum Riffgrund 3 Offshore Wind Farms.
Les Alizés’ hybrid setup
The power plant on board is a hybrid setup, which helps to reduce CO2 emissions. To optimize engine loading and recover the potential energy returned from the heavy lift crane, the arrangement combines diesel-driven generators with battery and drive technology. The ultra-low emission vessel can run on second-generation biodiesel, which reduces the fuel carbon footprint by up to 90%, further reducing the carbon footprint of installation activities.
Les Alizés is an ultra-low emission vessel with a cutting-edge dual exhaust filter system that removes up to 99 percent of nanoparticles from emissions using a diesel particulate filter (DPF) and reduces NOx emissions and other pollutants using a selective catalytic reduction system (SCR) to EU Stage V standards. Les Alizés and Voltaire will be the world’s first two seaworthy installation ships with ultra-low emissions.
