Turnover increased at DEME’s offshore energy division increased 11% year-to-date, according to the contractor’s third-quarter trading update.
The company said the growth to almost €1.7bn reflected sustained vessel utilisation and activity across its global portfolio.
Management reiterated that full-year turnover will be at least in line with 2024 and forecast a strong improvement in EBITDA, with the margin expected to land between 20% and 22%.
The offshore energy order book rose to €4.2bn from €3.8bn a year earlier, supported by follow-on work and new awards including Formosa 4 in Taiwan and Nordseecluster B in Germany.
DEME also took delivery of the new offshore installation vessel Norse Wind in October, which is scheduled to start operations in the first half of 2026 on European wind projects. Its sister vessel Norse Energi is due early next year.
