Live testing conditions make Solvang an attractive technology partner across several fields of maritime development. In 2023, projects in and outside of dry docking demonstrated a high outcome in terms of energy efficiency. The results span from propulsion drivetrain optimization, to friction-limitation by hull improvement, through to exhaust cleaning and last – but not least – part load optimization and operational improvement. Solvang’s Fleet Director Tor Øyvind Ask offers and account of which measures really make a difference in deep-sea green technology.
