Satellite ocean current tracking to cut fuel bill, tests suggest
BY merging measurements from satellites, the European Space Agency (ESA) is providing ocean current information that can mean cost savings to shipping, according to Isle of Man-based Phys.Org, an international scientific news portal.
Shipping companies forecast ocean currents down to a depth of 15 metres to route their vessels to avoid currents that would slow them down, said the report.
Ocean scientists have now teamed up with French shipping giant CGM-CMA to optimise routing using Globcurrent data, said the report.
Combining satellite measurements such as sea-surface height and temperature, surface winds and gravity, along with measurements, can yield a view of current circulation, it said.
ESA's Globcurrent project has merged measurements to build a picture of daily global ocean surface currents over the last 24 years.
Shipping companies can use this information to understand general circulation characteristics of particular regions.
Building on Globcurrent, a near-realtime product would then allow them to choose the most reliable forecast for a given time and location.
Said CGM CMA official Patrice Bara: "Using existing ocean forecast products gives us a 0.4 per cent cost saving. However, Globcurrent could help us achieve savings of up to 1.2 per cent on fuel."
