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.
FuelEU & EU ETS compliance costs for a 3,000 TEU Panamax containership
This case study determines the costs of compliance for a 3,000 TEU Panamax containership with respect to FuelEU and EU ETS. Estimated annual compliance costs for business as usual range from $2.5M in 2025 to $23M in 2050. Two different pathways are evaluated to determine mitigation options and OPEX costs: shore power and wind-assisted propulsion. Savings for shore power are approx. $400k per year in 2025, savings for wind-assisted propulsion are approx. $600k in 2025.
