Why slower sailing does not always mean lower fuel consumption

In maritime operations, it is commonly assumed that reducing vessel speed lowers fuel consumption. While true in stable conditions, real-world voyages are shaped by evolving weather and sea state, and the relationship between speed and fuel use is not always what it seems.

Maritime route optimisation: how small adjustments can deliver up to 10-15% fuel savings

Weather routing is not just about avoiding storms, it is about finding the optimal balance between speed, sea state, and fuel burn across the full passage. Small course and speed adjustments, made at the right moment, compound into significant savings.

MWI: the first company to map weather fronts in the maritime sector

Marine Weather Intelligence has developed a methodology to detect and map weather fronts at sea, zones of sudden wind shifts, cross seas, and gusts that many maritime charts no longer represent. The approach was tested during the Vendée Globe 2024.
