DEME Group has named its new jack-up offshore transport and installation vessel, Norse Energi, at the company’s Flushing base in the Netherlands, strengthening its offshore wind installation fleet.
The ceremony followed the recent naming of sister vessel Norse Wind in Oslo. The two vessels are designed as a high-capacity installation pair for larger offshore wind turbines and XXL monopiles in European waters.
Norse Energi is scheduled to begin work in June 2026 at the Windanker offshore wind farm in the German Baltic Sea for Iberdrola. The vessel is then expected to move to Ørsted’s Hornsea 3 offshore wind project in the United Kingdom during the third quarter of 2026.
The vessel is built to transport and install next-generation wind turbine components and XXL monopiles in water depths of up to 70 m. Like Norse Wind, it is equipped with a 3,200 t crane and can carry several large turbine components in a single voyage, helping improve offshore installation efficiency.
DEME Group said both vessels feature hybrid power systems with a 4.2 MWh battery installation. The system is designed to absorb energy peaks during offshore work, reduce engine load, improve fuel efficiency and lower emissions.
Luc Vandenbulcke, chief executive officer of DEME Group, said Norse Energi and Norse Wind support the company’s plan to expand offshore wind installation capacity as turbines and foundations become larger. The vessel was officially named by Fabienne Ackermans, a descendant of DEME Group’s founding family.
The vessel is entering service as European offshore wind projects require installation assets capable of handling heavier and larger components in markets including the North Sea and Baltic Sea. DEME Group reported turnover of EUR 4.2 billion and EBITDA of EUR 931 million in 2025, supported by around 6,000 employees across offshore energy, dredging, marine infrastructure and environmental remediation.
