The aim is to utilise technologies that enable particularly low-noise and low-emission research at sea and in the polar regions. CEO Oliver Burkhard emphasised the importance for TKMS: \"By selecting the complex propulsion system for the new Polarstern, we are ensuring that we meet the high customer requirements for reliability, environmental protection and sustainability.\"<\/p>\n<p>Drive technology for sustainable and emission-free research Four generator sets from W\u00e4rtsil\u00e4 were selected for power generation. Two of the engines are dual-fuel-capable, meaning that they can run on methanol as well as conventional diesel. In addition to a sustainable energy supply, a complex battery system will be integrated into the new Polarstern to enable completely emission-free research operations. A highly effective diesel particulate filter cleans the exhaust gases produced during diesel operation before they are treated in an SCR catalytic converter from W\u00e4rtsil\u00e4. Two rudder propellers from Finnish company Steerprop and a fixed centre propulsion system from Finnish manufacturer Aker Arctic are used for propulsion. The entire propulsion system is designed to fulfil the highest climate and environmental protection requirements. The Polarstern is scheduled to be handed over to the Alfred Wegener Institute research community in 2030.<\/p>\n<p data-start=\"132\" data-end=\"173\"><strong>Technical data on the drive system<\/strong><\/p>\n<ul data-start=\"175\" data-end=\"585\">\n<li data-start=\"175\" data-end=\"239\">\n<p data-start=\"177\" data-end=\"239\"><strong data-start=\"177\" data-end=\"196\">Overall performance:<\/strong> W31 four-stroke generator sets - 33.1 MWe<\/p>\n<\/li>\n<li data-start=\"240\" data-end=\"294\">\n<p data-start=\"242\" data-end=\"294\"><strong data-start=\"242\" data-end=\"279\">Storage capacity battery system<\/strong> (correction): An approx. 17,800 kWh battery system enables emission-free measurements without fuel consumption for 2 - 3 hours<\/p>\n<\/li>\n<li data-start=\"295\" data-end=\"459\">\n<p data-start=\"297\" data-end=\"459\"><strong data-start=\"297\" data-end=\"352\">SCR catalytic converter (selective catalytic reduction):<\/strong> Conversion of up to 90 % of climate-damaging nitrogen oxide emissions into elemental nitrogen and water<\/p>\n<\/li>\n<li data-start=\"460\" data-end=\"541\">\n<p data-start=\"462\" data-end=\"541\"><strong data-start=\"462\" data-end=\"533\">Diameter rudder propeller (azimuth propulsors SP 160 PULL ARC LM):<\/strong> 4,8 m<\/p>\n<\/li>\n<li data-start=\"542\" data-end=\"585\">\n<p data-start=\"544\" data-end=\"585\"><strong data-start=\"544\" data-end=\"577\">Centre propeller diameter:<\/strong> 5,4 m<\/p>\n<\/li>\n<\/ul>","protected":false},"excerpt":{"rendered":"<p>Das Auftragsvolumen umfasst Generatorens\u00e4tze, Propulsionsaggregate und\u00a0Systeme wie Methanolaufbereitung und Abgasnachbehandlung.
