Havyard is using digital modelling to optimise its battery-powered ferries' energy consumption in line with real-life operational conditions.

Fosnavaag-based Havyard on Tuesday delivered its third battery-run ferry to transport company Fjord1, which will operate the vessel across the Sulafjord on the Hareid–Sulesund route in Norway.

The shape of the ferry's hull and other features were optimised by testing a digital model of the vessel in a "virtual test tank" of the Sulafjord, built using data on local conditions.
