Propulsion in a Seaway

  • The ocean environment reduces vessel speed and increases the propulsion power required to maintain course and velocity.
  • Kongsberg Maritime researches the added hull resistance and propulsion effects caused by waves and other environmental forces, using model tests, full‑scale measurements and advanced computational modelling.
  • Our prediction tools are continuously developed to account for wave influence when estimating power–speed performance and propulsion‑related energy consumption.
  • The time histories shown on the right illustrate a full‑scale case study of how propulsion power and vessel speed vary for a 130‑metre ship when sailing from a sheltered fjord on the Norwegian coast into the open ocean, before entering another sheltered area.
