Deme's New WTIV Extends 124-Meter Long Base Prior to Fourth Quarter 2025 Delivery
The offshore wind industry is set to receive a significant boost with the upcoming delivery of DEME's next-generation wind turbine installation vessels (WTIVs), Norse Wind and Norse Energi. These NG20000X-class vessels, designed by GustoMSC, are engineered to handle wind turbines with rotor diameters over 300 meters and XXL monopiles weighing up to 3,000 tons, operating effectively in water depths of up to 70 meters[1][2][3].
Specifications:
The vessels boast impressive specifications. With a vessel leg length of 124 meters (approximately 91 meters above seabed during jacking), they are well-equipped to install turbines of substantial size. They are also capable of handling XXL monopiles and are designed to operate effectively in depths of up to 70 meters[1][2][3][4][5].
Construction Timeline:
The construction of Norse Wind is well underway, with the shipyard starting its build in the fourth quarter of 2022. Norse Wind is scheduled for delivery to DEME in the fourth quarter of this year, while Norse Energi is expected for delivery in early 2026[1][2][3]. Recently, Norse Wind successfully completed its full-height jacking test, extending legs to full length and validating structural integrity and safety systems, marking a significant milestone in commissioning[1][2][3][5].
Carbon Emission Reduction Features:
Although the specific carbon emission reduction technologies are not detailed, the vessels' high installation efficiency for large-scale offshore wind turbines supports the global clean energy transition. By enabling the deployment of more powerful wind turbines and large monopiles faster and potentially with fewer trips offshore, they contribute indirectly to carbon reduction by facilitating renewable energy infrastructure with modern, efficient vessels[1][2][3].
In addition, the vessels are equipped with the latest battery hybrid drive train technology, designed to reduce carbon emissions per MW installed by over 70% compared to previous vessel models[1][2][3]. Once operational, Norse Wind and Norse Energi will be the most modern WTIVs in the industry, according to DEME.
