A Report by Cornelia Borrmann Polar researchers in Europe are planning a new vessel that will be able to overcome thick sea ice and stormy seas. Designed under the auspices of the Alfred Wegener Institute, the "Aurora Borealis" may be the world’s strongest icebreaker, a research ship which will be able to drill 1,000 meters into the ocean floor. The ship is due to be completed in 2014. The Aurora Borealis will be an icebreaker, research ship and deep-sea drilling platform in one. It's designed to take sediment samples from the polar seabed - even in thick drift ice. Designing the icebreaker was a challenge for the engineers. It's new kind of boat - and innovations had to be made, from the hull up.   A model about seven meters long is being used to see if the design is seaworthy. The first tests show that at slow speed, the boat can plow through ice three metres thick. And the underside remains ice-free. A ship able to survive thick ice and on a stormy sea The next trial for the model is in ice-free waters. This time, it's a simulation of a voyage over the equator - along the African coast. There the boat would have to surmout waves ten meters high. Eberhard Wagner gives a positive summary: "Even with the heavy seas that we saw today, we discovered that the deck area for the drilling rig stays nearly 100 percent free of water. That means conditions for the scientists are optimal." Against disruptive forces - Aurora Borealis will be cruising mainly through ice-covered waters The researchers aboard the Aurora Borealis will be cruising mainly through ice-covered waters. To meet this challenge, a system of weights is used to make the model roll and list in a controlled fashion. This ability to sway will enable the icebreaker to overcome the thickest of obstacles. The Aurora Borealis is later expected to master ice ridges up to 15 meters high. But the icebreaker can only drill in the ice if it can maintain its position, meaning it has to break ice w...
