Interactive map and drone video: TTÜ scientists developing better method of navigating sea ice
The result of work done by marine scientists at the Tallinn University of Technology, it is now possible to monitor and predict navigation conditions on ice covered seas in real time.
Developed at the Marine Systems Institute of the Tallinn University of Technology’s (TTÜ), the specially engineered measurement system, designed to attach directly to the ship itself, records ice conditions and reports them to users in real time (view site in English).
The forecasting model, which is based on a mathematical system referred to as fuzzy logic, makes it possible to predict changes in ice conditions up to 48 hours in advance; this can also be tracked on its web application. The level of resistance to the ship caused by the ice can fluctuate a great deal, and this forecast can help both save fuel, possibly up to 30-40%, and make ship traffic in ice smoother and safer, reported TTÜ.
“While this winter has been mild, there is still ice on the sea, and TTÜ's marine scientists can study the effects of ice conditions on ship traffic,” noted the Marine Systems Institute’s senior researcher Tarmo Kõuts. “We have been able to conduct studies for nearly two months in Pärnu Bay, where we have charted the extent and different types of sea ice.”
Under Kõuts’ direction, researchers at TTÜ's Marine Systems Institute also use satellites, radar information as well as drones to gather and analyze data. You can see drone video of the Estonian Maritime Administration’s icebreaker at work in Pärnu Bay on February 18, 2016 by clicking here.
