Fuel and compliance costs for offshore workboat in North Sea
Operating an offshore workboat in the North Sea area until 2050 will impose significant financial and operational pressure due to tightening environmental regulations and mounting compliance obligations. Modelling of compliance costs shows a clear tipping point in 2040, with FuelEU Maritime becoming the dominant driver, although FuelEU currently applies to vessels above 5,000 GT only. Results for a large offshore workboat operating year-round in the North Sea show that the maximum projected cost exposure could reach up to $250 million between now and 2050.
