Green shipping corridors alone may not deliver maritime decarbonisation at the required scale. This research proposes regional alliances of ports that aggregate demand for renewable energy and zero-emission fuels, accelerate infrastructure investment, and reduce competitive risks. The findings outline a collaborative pathway for faster, more resilient industry-wide emissions reduction today.

Vessel efficiency extends far beyond maximum speed. By combining detailed route analysis with tailored waterjet selection and design, engineers can optimise performance across an asset’s entire operating profile. The approach reveals new methods for balancing competing demands, unlocking fuel savings, operational efficiency and smarter propulsion decisions in practice today onwards.
