CTV (Crew Transfer Vessel) Fuel & CO₂
Offshore-wind Crew Transfer Vessels - fast cats that ferry technicians from shore to turbines. Outside CII scope; operators benchmark per technician-transfer.
Operational year

Annual CO₂

Daily fuel

CO₂ per transfer
320.600kg / transfer
Formula, assumptions, and limits
$$\text{CO}_2^\text{year} = \sum_j F_j \cdot C_{f,j}$$
$$\text{Intensity} = \frac{\text{CO}_2 \cdot 1000}{N_\text{transfers}}$$
Diesel CTVs emit ~ 120–200 kg CO₂ per transfer. Hybrid and fully-electric CTVs entering service (Damen, Chartwell) target < 50 kg per transfer on short legs (< 25 nm round-trip).
