Weather Routing Services

Weather Routing Service aims to find the optimum route between 2 positions at sea. Many times, the shortest distance is not the quickest route, due to the presence of wind, currents and waves which can seriously affect the speed of a ship, and have to be forecasted in advance, in order to construct an optimum route that saves time and bunkers. The calculation of the optimum route should integrate various data:

  • Type of Vessel and Condition (Ballast or Laden)
  • Wind forecast and generated Wind Waves
  • Swell forecast
  • Expected Tide and Ocean Surface Currents

The objectives of weather routing are generally the following:

  • Avoid sailing in too strong winds and gusts
  • Avoid Tropical Cyclones or Developments
  • Avoid navigational areas with strong adverse currents
  • Avoid where sea state is difficult, e.g. strong effect of adverse and long swells
  • Maintain an optimum ETA at destination
  • Minimize fuel consumption
