Formula, assumptions, and limits
$$\text{CO}_2^\text{year} = \sum_j F_j \cdot C_{f,j}$$
$$\text{Intensity} = \frac{\text{CO}_2 \cdot 1000}{N_\text{tech-days}}$$
Modern SOVs (Edda Wind, Esvagt, Ulstein) use diesel-electric with battery peak-shaving and walk-to-work gangways. Best-in-class ~ 80 kg CO₂/technician-day; industry median 120–180.
